On behalf of the organizing committee, it is our great pleasure to welcome you to Seoul, South Korea and the 17th ACM International Conference on Mobile Systems, Applications, and Services (MobiSys 2019). MobiSys has been the premier venue for cutting-edge research in mobile systems and applications since its inception in 2003. We are delighted that the steering committee, led by Victor Bahl, has decided to bring the conference to Seoul this year. We are proud that the program committee, led by the co-chairs, Rajesh K. Balan and Nicholas D. Lane, has compiled an excellent technical program. The committee has done a fabulous job in selecting 39 excellent papers from 172 submissions. We would like to acknowledge the tremendous efforts of these individuals for making the outstanding program. In addition to the regular sessions of the main conference, we host a number of exciting adjunct programs. First, we have significantly enhanced poster as well as demo and video sessions, featuring 72 posters, 24 demos, and 7 video presentations. We expect that these sessions will serve as a valuable venue for open discussion and communication among the presenters and audience on interesting on-going works and future research directions. We are thankful to the poster chairs, Karthik Dantu, Dongsu Han, and Inseok Hwang, and the demo and video chairs, Chulhong Min and Mi Zhang, for their enormous efforts to compose and organize these sessions. We continue the tradition of having multiple workshops on emerging and evolving topics, which bring the MobiSys community to discuss potential new directions for future mobile systems. The workshop chairs, Z. Morley Mao and Seungwoo Kang, have done an excellent work and deserve a special acknowledgment for coordinating five interesting workshops. We also thank all the individual workshop chairs for their efforts in organizing their workshops. We are proud to feature the Rising Stars Forum, a venue for young scholars, including Ph.D. students as well as fresh Ph.D.'s, to present their recent works and get useful advices for their early career. This special forum has come true by the dedication of the two rising stars forum chairs, Hsin-Mu Tsai and Chenren Xu. MobiSys 2019 hosts three impressive keynote speakers: Professor Kang G. Shin from the University of Michigan will give a talk titled "Marriage of Smart Phones with Smart Cars", and Professor Gregory D. Abowd from Georgia Institute of Technology will speak on "The Material of the 21st Century: Moving beyond Moore and Weiser," and Roy Want from Google, the winner of the SIGMOBILE Outstanding Contribution Award (OCA), will share his valuable experiences and vision in his OCA talk.
Precise UE positioning in UMTS using cumulative virtual blanking (2002)

The current Observed Time Difference of Arrival technique for finding the position of a mobile in a UMTS network suffers from a severe near-far problem when the UE is close to a Node B. We describe a new technique, called Cumulative Virtual Blanking, for overcoming this problem efficiently, without disrupting the normal operation of the network. Early results from a network-based trial indicate positioning accuracy of the order of 20 m in a rural environment.
Surface deformations as a necessary requirement for resistance switching at the surface of SrTiO3:N (2013)

Atomic force microscopy (AFM), conductive AFM and electrochemical strain microscopy were used to study the topography change at the defect surface of SrTiO3:N, breakdown in the electrical conduction of the tip/sample/electrode system and ionic motion. The IV curves show resistance switching behavior in a voltage range ±6 V < U <± 10 V and a current of maximum ±10 nA. A series of sweeping IV curves resulted in an increase in ionically polarized states (surface charging), electrochemical volume (surface deformations) and sequential formations of stable surface protrusions. The surface deformations are reversible (U <± 5 V) without IV pinched hysteresis and remained stable during the resistance switching (U >± 6 V), revealing the additional necessity (albeit insufficient due to 50% yield of working cells) of surface protrusion formation for resistance switching memory.
Immersive Meeting Point An Approach Towards Immersive Media Portals (2004)

Natural and realistic video communication and collaboration across long distances is an essential, requirement in the context of globalization. Against this background this paper presents a next generation system - the immersive meeting point - which bridges the gap between cutting-edge technology available from research laboratories and advanced prototype systems beeing close th the market. The aim is to provide immversive tele-presence and natural representation of all participants in a shared virtual meeting space to enhance quality of humancentred communication. This system is based on the principle of a sharedvirtual table environment, which guarantees correct eye contact and gesture reproduction. The current system design and details of the algorithms als well as the software concept are resented.
Forecasting in multivariate irregularly sampled time series with missing values (2020)

Sparse and irregularly sampled multivariate time series are common in clinical, climate, financial and many other domains. Most recent approaches focus on classification, regression or forecasting tasks on such data. In forecasting, it is necessary to not only forecast the right value but also to forecast when that value will occur in the irregular time series. In this work, we present an approach to forecast not only the values but also the time at which they are expected to occur.

Impedance Resonance in Narrow Confinement (2018)

The article explores the ion flux response of a capacitor configuration to an alternating voltage. The model system comprises a symmetric binary electrolyte confined between plan-parallel capacitor plates. The alternating current response is investigated for the sparsely studied albeit practically important case of a large amplitude voltage applied across a narrow capacitive device, with the distance between the two plates amounting to a few ion diameters. Dynamic density functional theory is employed to solve for the spatiotemporal ion density distribution as well as the transient ion flux and complex impedance of the system. The analysis of these properties reveals a hitherto hidden impedance resonance. A single ion analogue of the capacitor, which is equivalent to neglecting all interactions between the ions, is employed for a physical interpretation of this phenomenon. It explains the resonance as a consequence of field-induced ion condensation at the capacitor plates and coherent motion of condensed ions in response to the field variation.
ANTNets: Mobile Convolutional Neural Networks for Resource Efficient Image Classification (2019)

Deep convolutional neural networks have achieved remarkable success in computer vision. However, deep neural networks require large computing resources to achieve high performance. Although depthwise separable convolution can be an efficient module to approximate a standard convolution, it often leads to reduced representational power of networks. In this paper, under budget constraints such as computational cost (MAdds) and the parameter count, we propose a novel basic architectural block, ANTBlock. It boosts the representational power by modeling, in a high dimensional space, interdependency of channels between a depthwise convolution layer and a projection layer in the ANTBlocks. Our experiments show that ANTNet built by a sequence of ANTBlocks, consistently outperforms state-of-the-art low-cost mobile convolutional neural networks across multiple datasets. On CIFAR100, our model achieves 75.7% top-1 accuracy, which is 1.5% higher than MobileNetV2 with 8.3% fewer parameters and 19.6% less computational cost. On ImageNet, our model achieves 72.8% top-1 accuracy, which is 0.8% improvement, with 157.7ms (20% faster) on iPhone 5s over MobileNetV2.
Fatigue Crack Propagation Behavior of 316L Stainless Steel and Frequency Characteristics of its Acoustic Emission (2000)

We investigated the fatigue crack propagation of base metal, weld metal and heat attected zone in 316L stainless steel. And we analysed acoustic emission signals during the fatigue test by time-frequency analysis method. The specimens of weld metal and HAZ had longer fatigue life and slower rate of crack propagation better than base metal. And as a result of time-frequency was 200-300 kHz was obtained by fatigue crack propagation and 500 kHz was obtained by dimple and separate of inclusion.
Spatiotemporal assignment of energy harvesters on a self-sustaining medical shoe (2012)

We present a new method for spatiotemporal assignment and scheduling of energy harvesters on a medical shoe tasked with measuring gait diagnostics. While prior work exists on the application of dielectric elastomers (DEs) for energy scavenging on shoes, current literature does not address the issues of placement and timing of these harvesters, nor does it address integration into existing sensing systems. We solve these issues and present a self-sustaining medical shoe that harvests energy from human ambulation while simultaneously measuring gait characteristics most relevant to medical diagnosis.
Impact of sand content on filter cake and invert emulsion drilling fluid properties in extended reach horizontal wells (2018)

In this paper, we evaluated the effect of sand content on the properties of the drilling fluid and filter cake during drilling a long horizontal section in sandstone reservoirs. Sixteen drilling fluid samples were collected and the initial properties were measured such as density and rheological parameters. HPHT tests were performed at 500 psi (the back pressure was 200 psi) to build the filter cake. The obtained results showed that the presence of sand caused significant change in the properties of mud and filter cake. The thickness of the filter cake increased about 35% to 40% of its original thickness. The mud yield point and 10 min gel strength increased by 40% due to the increase in sand content in the mud. Based on the real field data, empirical correlations were developed to predict the sand content in the filter cake using the drilling fluid properties measurements during drilling.

<title>Design and verification of the Far Ultraviolet Spectrographic Imager (FUV-SI) for the IMAGE mission</title> (1998)

The IMAGE FUV-SI is simultaneously imaging auroras at 121.8 nm and 135.8 nm. The spectrograph design challenge is the efficient rejection of the intense Lyman-alpha emission at 121.6 nm while passing its Doppler-shifted component at 121.8 nm. The FUV-SI opto-mechanical design, analysis integration, and verification of performances against environment are discussed in this paper. In absence of STM environmental constraints at subsystem levels are derived analytically from F.E.M. and used for pre-qualifying optical subsystems.
Ring Transformations of Heterocycles 2. Ring Contraction of 5,6-Dihydro-4H-1,2,4,5-oxatriazines into 1H-1,2,4-Triazoles (1993)

6-Monosubstituted 5.6-dihydro-4H-1.2.4.5-oxatriazines (3) undergo ring contraction, via elimination of HzO.to yield the respective 1H-1,2,4-triazoles ( 4 ) .This transformation is envisaged to proceed via the ring-opened (E)-hydrazonoxime (5) which then suffers dehydrative cyclization.The process is acid-catalyzed and is thermally induced.Apparently, the driving force for this transformation is linked to the aromaticity of the triazole product.Recently, we have reported2 on the synthesis of 5.6-dihydro-4H-1,2.4,5oxatriazines(3) via direct interaction between methylhydrazones (2) and nitrile oxides, generated in situ from the appropriate arylhydroxamoyl chloride precursors (1) by the action of triethylamine.The chemistry of these heterocycles remains, however, unexplored.The present work aims at investigating the thermal stability of model dihydro-oxatriazines 13).For this purpose we have prepared an additional set of these heterocycles following the above-mentioned route (Scheme 1).'
ChemInform Abstract: Steric and Electronic Factors Influencing the Amounts of μ‐Alkylidyne and μ‐Alkenyl Products Obtained from Reaction of Diiron Methylidyne Complexes with Alkenes. (1987)

Abstract The reaction of (I) with monosubstituted alkenes gives μ‐alkylidyne products (II), which are characterized by deprotonation to give the μ‐alkenylidene complexes (III).
Vacuum Filtration of Metal Hydroxide Sludges (1980)

The characterization of metal hydroxide sludges was approached from the viewpoint of developing a fundamental understanding of the mechanisms that define the response of these sludges to vacuum dewatering. Both individual metal and mixed-metal sludges were characterized by standard dewatering test procedures. Of the sludge parameters investigated, the characteristic floc size distribution had the greatest effect on the observed sludge dewatering rate. An empirical equation was developed that allowed for the rapid prediction of sludge specific resistance based upon a measurement of particle size. Metal hydroxide sludges were found to be amenable to polymer conditioning for improved vacuum dewatering rates. The mechanism of polymer action was determined to be interparticle bridging. Optimum polymer conditioning doses were correlated to the available floc surface area present in a sludge sample.
Vascular remodeling of the mouse yolk sac requires hemodynamic force (2007)

The embryonic heart and vessels are dynamic and form and remodel while functional. Much has been learned about the genetic&#13;\nmechanisms underlying the development of the cardiovascular system, but we are just beginning to understand how changes in&#13;\nheart and vessel structure are influenced by hemodynamic forces such as shear stress. Recent work has shown that vessel&#13;\nremodeling in the mouse yolk sac is secondarily effected when cardiac function is reduced or absent. These findings indicate that&#13;\nproper circulation is required for vessel remodeling, but have not defined whether the role of circulation is to provide mechanical&#13;\ncues, to deliver oxygen or to circulate signaling molecules. Here, we used time-lapse confocal microscopy to determine the role of&#13;\nfluid-derived forces in vessel remodeling in the developing murine yolk sac. Novel methods were used to characterize flows in&#13;\nnormal embryos and in embryos with impaired contractility (Mlc2a^(–/–)). We found abnormal plasma and erythroblast circulation in&#13;\nthese embryos, which led us to hypothesize that the entry of erythroblasts into circulation is a key event in triggering vessel&#13;\nremodeling. We tested this by sequestering erythroblasts in the blood islands, thereby lowering the hematocrit and reducing shear&#13;\nstress, and found that vessel remodeling and the expression of eNOS (Nos3) depends on erythroblast flow. Further, we rescued&#13;\nremodeling defects and eNOS expression in low-hematocrit embryos by restoring the viscosity of the blood. These data show that&#13;\nhemodynamic force is necessary and sufficient to induce vessel remodeling in the mammalian yolk sac
Dual electro/piezo property functionally graded piezoceramics (2006)

Conventional piezoceramic actuators employ architectures which are designed to amplify the small displacements of the bulk material; however, these gains in deformation come at the cost of reduced reliability because of their bonded construction. The goal of this research was to invent a synergistic piezoceramic grading technique and the necessary theoretical foundation for its analysis and synthesis, which coupled with advanced fabrication processes, established a reliable monolithic distributed actuation technology. The novel Dual Electro/Piezo Property (DEPP) gradient was invented to simultaneously exploit variations in the piezoelectric properties and permittivity to create high performance, energy efficient piezoceramics that match the capabilities of other gradient techniques at half the driving electric potential. This grading technique was implemented via an adapted Micro-Fabrication by Co-eXtrusion (MFCX) process which can generate precise, finely controlled material gradients across multiple dimensions, and was used to create the first monolithic piezoceramic actuators that produce higher order, distributed deformations. To accurately predict the behavior of these advanced graded piezoceramic actuators, a versatile analytic modeling methodology, incorporating all the characteristics, behaviors, and effects of thickness and thickness/length graded piezoceramics, was derived to predict the performance capabilities of FGP actuators under a combination of electrical activation and external mechanical loading. The enhanced reliability of DEPP FGP was explored through extensive numeric and analytic stress modeling, displaying potential stress reductions of up to 86.2% with only a 32.5% cost in device deflection, allowing for the tailoring of FGP to the demands of individual applications. Initial experimental fatigue testing of DEPP FGP show a potential four order of magnitude improvement over conventional actuators, making graded actuation better suited for applications where reliability is a paramount concern. This dissertation lays the necessary foundation for the design, modeling, fabrication, and testing of DEPP FGP actuators, taking the first steps in bringing this exciting emerging actuation technology to maturity.
Encapsulation of Essential Oils in Zein Nanospherical Particles (2005)

Three essential oils, oregano, red thyme, and cassia (100% pure oil), were encapsulated by phase separation into zein nanospheres. Topographical images indicated that the powders were made up of irregularly shaped particles ( approximately 50 mum) containing close-packed nanospheres. Approximately 31% of the oregano encapsulated particles had mean diameters greater than 100 nm compared to 19% for the zein alone particles. In vitro digestion of zein particles with pepsin at a concentration ratio of 10:1 was complete after 52 h in phosphate-citrate buffer, pH 3.5, at 37 degrees C by spectroscopic analysis. Nonenzymatic, aqueous in vitro release of essential oils from encapsulated zein particles was carried out in phosphate buffered saline at pH 7.4 and 37 degrees C. Release occurred at varying rates over 20 h probably from different locations within the closely packed nanospheres of different sizes. Gel electrophoresis SDS-PAGE of zein incubated with freeze-dried swine manure solids at 37 degrees C indicated that preformed microbial enzymes capable of digesting zein within minutes were present in the manure. Except for differences in size of nanospheres, no structural differences were resolved by several microscopic methods, suggesting that the oil and proteins phases were blended during phase separation.
Mucosa-associated microbiota dysbiosis in colitis associated cancer (2017)

Gut microbiota dysbiosis has been associated with inflammatory bowel diseases (IBD). In colorectal cancer, the gut microbiota has also been recognized as potentially involved in aggravating or favoring the tumor development. However, very little is known on the structure and role of the microbiota in colitis associated cancer (CAC), an important complication of IBD in human. Here we analyzed the bacterial and fungal composition of the mucosa associated microbiota of patients suffering CAC, sporadic cancer (SC) and of healthy subjects (HS) by barcode sequences analysis on the following cohort: 7 CAC patients, 10 SC patients and 10 HS using 16S (MiSeq) and ITS2 (pyrosequencing) sequencing, for bacteria and fungi respectively. Mucosa-associated bacterial microbiota in CAC was significantly different from the ones in SC or in HS, while the fungal showed no differences. Comparison between mucosa-associated microbiota on the tumor site or in normal mucosa near the tumor showed very similar patterns. The global mucosa-associated bacterial microbiota in cancer patients was characterized by a restriction in biodiversity but no change for the fungal community. Compared to SC, CAC was characterized by an increase of Enterobacteriacae family and Sphingomonas genus and a decrease of Fusobacterium and Ruminococcus genus. Our study confirms the alteration of the mucosa-associated bacterial microbiota in IBD and SC. Although the cohort is limited in number, this is the first evidence of the existence of an altered bacterial microbiota in CAC clearly different from the one in SC patients.
Stereo Side-Looking Radar Experiments (1980)

The application of side-looking radar images in geoscience fields can be enhanced when using overlapping image strips that are viewed in stereo. A question concerns the quality of stereo radar. This quality is described evaluating stereo viewability and using the concept of vertical exaggeration with sets of actual radar images. A conclusion is that currently available stereo radar data are not optimized, that therefore a better quality can be achieved if data acquisition is appropriately arranged, and that the actual limitations of stereo radar are still unexplored.
Al-, Nb-, and Ta-Based Perfluoroaryloxide Anions as Cocatalysts for Metallocene-Mediated Ziegler−Natta Olefin Polymerization (2000)

Perfluoroaryloxide salts of the formula Ph3C+Al(OC6F5)4- and Ph3C+M(OC6F5)6- (M = Nb, Ta) have been synthesized and characterized. In combination with sterically encumbered zirconocene dimethyl complexes, they yield active ethylene polymerization catalysts.
Antenna‐coupled VOx thin‐film microbolometer array (2003)

Abstract Two‐dimensional arrays of log‐periodic antenna‐coupled microbolometers were fabricated using VOx and Nb thin films as bolometric materials, which have different temperature coefficients of resistance. Noise, response, and angular characteristics of both types of microbolometer arrays were measured and compared. VOx‐based devices presented a 4.5× better response and 5.5× better signal‐to‐noise ratio than Nb‐based devices. Radiation patterns show that a further increase in response can be obtained by better matching the VOx bolometer to the antenna elements. © 2003 Wiley Periodicals, Inc.

Laser-induced birefringence in fused silica from polarized lasers (2005)

Fused silica, when exposed to excimer laser light, exhibits permanent anisotropic birefringence and wavefront changes. These laser-induced changes depend on the silica composition and processing conditions. The optical anisotropy is most clearly observed in samples that are exposed with linear polarization. This polarization-induced effect has been known for several years, but has become much more important with the advent of immersion lithography and its associated very high numerical apertures. High numerical aperture optics require controlled polarization, notably linear polarization, in order to maintain phase contrast at the image. When birefringence and wavefront changes are induced by laser exposure, the image contrast at the wafer deteriorates. We interpret the changes in optical properties in terms of permanent anisotropic strain induced by laser damage, and the associated strain-induced optical effects. This is accomplished using the mathematics of tensors to account for anisotropic strain and optical anisotropy, and using finite element analysis to calculate the strain fields taking the sample and exposure geometries into account. We report the relations between underlying density and strain anisotropy changes and the induced birefringence and wavefront for a given experimental sample geometry. We also report some examples of the different degree of laser damage from silica with different compositions and processing conditions.
