Discovering Urban Functional Zones Using Latent Activity Trajectories (2014)

The step of urbanization and modern civilization fosters different functional zones in a city, such as residential areas, business districts, and educational areas. In a metropolis, people commute between these functional zones every day to engage in different socioeconomic activities, e.g., working, shopping, and entertaining. In this paper, we propose a data-driven framework to discover functional zones in a city. Specifically, we introduce the concept of latent activity trajectory (LAT), which captures socioeconomic activities conducted by citizens at different locations in a chronological order. Later, we segment an urban area into disjointed regions according to major roads, such as highways and urban expressways. We have developed a topic-modeling-based approach to cluster the segmented regions into functional zones leveraging mobility and location semantics mined from LAT. Furthermore, we identify the intensity of each functional zone using Kernel Density Estimation. Extensive experiments are conducted with several urban scale datasets to show that the proposed framework offers a powerful ability to capture city dynamics and provides valuable calibrations to urban planners in terms of functional zones.
Carbon-13 kinetic isotope effects. III. Temperature dependence of <i>k</i><sub>12</sub>/<i>k</i><sub>13</sub> for 1-bromo-1-phenylethane alcoholysis (1968)

The temperature dependence of k 12 /k 13 for methanolysis and ethanolysis at the α-carbon of 1-bromo-1-phenylethane has been determined over the ranges 25° and 45° respectively. It is found that the kinetic isotope effect increases with increasing temperature for these systems. This result offers support for earlier interpretations on the 13 C fractionations measured previously and the data are considered in terms of the original Bigeleisen equation. The results indicate that primary kinetic 13 C isotope effects may be useful for distinguishing between bimolecular and unimolecular substitution mechanisms.
On the Absorption of Acetylene and Di-Deutero-Acetylene in the Photographic Infrared (1935)

Using an absorbing column 9 meters long of over 90 percent pure ${\mathrm{C}}_{2}$${\mathrm{D}}_{2}$ at a pressure of 85 cm, we observed no absorption bands in the region 7000 to 11,500A. This lack of absorption is discussed. A new absorption band of ${\mathrm{C}}_{2}$${\mathrm{H}}_{2}$ is found with origin at 7859A when an absorbing column 7.5 meters long at 90 cm pressure is used. The possible vibrational transitions giving rise to this band are discussed.

Physical and Chemical Properties of Soil Aggregates in a Brunizem Soil (1958)

Abstract A surface sample of Sharpsburg silty clay loam was separated into aggregate fractions of diameters 4760 to 2380µ, 2380 to 1190µ, + … +, 37 to 18.5µ by means of rotary sieves and elutriators. A similar separation was made for primary particles. Each fraction of aggregates was analyzed for chemical and physical properties. The physical properties of aggregates were compared with those of primary particles. Data on water stability of aggregates show that as the diameter of aggregates decreased the stability increased. Particularly, aggregates of diameter 74 to 37µ and 37 to 18.5µ were different from the other fractions. Some of the differences in properties were: higher degree of aggregation, percentage of primary particles, available phosphorus, and exchangeable Ca ++ ; lower moisture retention, percentage of organic matter, total nitrogen content, and exchangeable H + . At complete water saturation, aggregates and particles wetted under partial vacuum held greater amounts of water on a volume basis than did aggregates and particles wetted under atmospheric pressure. However, as tension was applied, more water was released from the aggregates and particles wetted under partial vacuum than under atmospheric pressure. At increased tensions, the differences between the two methods of wetting were less marked. At tensions of 0.33 atm. and higher, the moisture contents were nearly identical. Aggregates treated with VAMA soil additive, under both vacuum‐wetting and atmospheric‐wetting, released more water at successive tensions than did those without the additive.
An in vitro method to study the effects of hematopoietic regulators during immune and blood cell development. (2007)

In adults, hematopoiesis occurs in bone marrow (BM) through a complex process with differentiation of hematopoietic stem cells (HSCs) to immune and blood cells. Human HSCs and their progenitors express CD34. Methods on hematopoietic regulation are presented to show the effects of the chemokine, stromal-derived growth factor (SDF)-1I and the neuropeptide, substance P (SP). SDF-1I production in BM stroma causes interactions with HSCs, thereby retaining the HSCs in regions close to the endosteum, at low oxygen. Small changes in SDF-1I levels stimulate HSC functions through direct and indirect mechanisms. The indirect method occurs by SP production, which stimulates CD34+ cells, supported by ligand-binding studies, long-term culture-initiating cell assays for HSC functions, and clonogenic assays for myeloid progenitors. These methods can be applied to study other hematopoietic regulators.
Fabrication of magic-mirror with magnetic polishing and end-milling on machining center (2014)

Recently, with the fabrication of the magic-mirror having the micro C2-continuous surface, it is difficult to hand down magic-mirror fabrication technology, due to downsizing of veteran engineers or even their successors. Therefore, the purpose of this study is to digitalize the magic-mirror fabrication technology using a CNC technology. The novel method which integrate a ball end-milling and magnetic polishing on a conventional machining center is proposed, and a workpiece that was machined by this method is groove cut with straight end-mill from opposite side of its. The micro deformation is occurred by residual stress during the groove cutting. And, in order to evaluate a surface integrity of machined workpiece, a magic-mirror testing which use an artificial sunlight is carried out. In this report, as the results, we signified an optimum ball end-milling condition and a requisite polishing amount, to generate a mirror surface efficiency with the magnetic polishing.

Casual Chocolate Consumption and Inhibition of Platelet Function (2007)

Observational studies have associated reduced cardiovascular mortality with chocolate consumption. Feeding studies of high-dose, flavanol-rich chocolate show antiplatelet effects, but the effect of casual chocolate consumption on platelet function is unknown. Healthy adults (N=1535) were proscribed from consuming foods affecting platelet function, including chocolate, for 48 hours and completed a 24-hour dietary recall before ex vivo platelet testing with the Platelet Function Analyzer (PFA)-100 (Dade Behring, Inc, Deerfield, IL) test and in vivo testing with urinary 11-dehydro thromboxane B2 (Tx-M) measurements. Some participants (n=141) reported ignoring the prohibition of consuming chocolate before platelet testing. Despite having similar baseline characteristics, chocolate consumers had longer PFA closure times (130 vs 123 seconds, P=.005) and decreased Tx-M levels (175 vs 290 ng/mol creatinine, P=.03). Chocolate remained a significant independent predictor of both ex vivo and in vivo platelet function testing after adjusting for confounders. The authors concluded that even consuming modest amounts of commercial chocolate has important antiplatelet effects.

UBV Light Curves of AR Lacertae During 1980-81 and 1981~82 (1982)

The UBV observations of the brightest RE CVn-type eclipsing binary star AR Lac were made at four observatories, two in Korea and two in the U.S. in the 1980-81 and 1981-82 seasons. As a result of the cooperation, two light curves in the yellow and in the blue were completed for each observing seasons. Ultraviolet observations were also made at three of the four observatories. The orbital period of AR Lac apparantly decreased around 1977. An analysis of our yellow light curves together with five other yellow curves available in the literature since 1975 shows that there seems no periodicity in the migration of the distortion waves. There is a gradual decrease of at least 0.m1 between 1976 and 1982 in the brightness of the cooler component if one assumes that the hotter component is constant.

Classification of epitaxy in reciprocal and real space: rigid versus flexible lattices (2017)

Early investigations of epitaxy focused on inorganic adsorbates consisting of atoms or few-atom molecules, where commensurate registries are predominantly encountered. Expanding such studies to larger (organic) molecules has revealed hitherto unknown types of epitaxy with coherence between adlayer and substrate lattices in just one direction. Here we review recent contributions to the fundamental understanding and modeling of epitaxy. By sorting the ideas brought forward in the literature and amending some basic algebraic considerations a universal scheme for the classification of lattice epitaxy is presented. Ultimately, the occurrence of the different types of epitaxy is made plausible by easy-to-grasp energetic arguments.
Nucleotide sequence of a fragment of SV40 DNA that contains the origin of DNA replication and specifies the 5' ends of "early" and "late" viral RNA. IV. Localization of the SV40 DNA complementary to the 5' ends of viral mRNA. (1977)

Cytoplasmic mRNA isolated from cells infected with SV40 was isolated by passage over oligo(dT)-cellulose columns. This RNA was annealed to SV40 DNA fragments produced by cleavage with EcoRII endonuclease. The RNA resistant to RNase digestion was analyzed by digestion with ribonucleases and oligonucleotide mapping. The results were compared with oligonucleotides from in vitro transcripts of the fragments and with whole genome SV40 cRNA which had been fractionated by hybridization to the fragments. The 5' ends of "early" and the large "late" SV40 mRNA, transcribed from opposite DNA strands, overlap for a region of 60 to 100 nucleotides. The region of overlap includes a portion of the segment of DNA containing the origin of DNA replication.
The effects of labor on infant mortality among small-for-gestational-age infants in the USA (2002)

Exposure to labor is associated with an increased risk of early neonatal death among SGA infants, especially at gestational ages below 32 weeks. Future randomized trials are warranted to determine the optimal obstetric management of these high-risk infants.
Effect of bite plane on electromyographic activity of masticatory muscles. Part 1. Muscle activity during tapping movement. (1989)

The purpose of this study is to examine the influence of the insertion of bite plane on masticatory muscle activity during tapping movement, and find out useful parameters for examination and diagnosis of stomatognathic dysfunction. The subjects in this study were twenty normal subjects with intact dentition and no signs of mandibular dysfunction as the control group, and twelve subjects with unilateral temporomandibular joint pain during jaw opening or closing movement as the patient group. Electromyographic activity in the bilateral anterior temporal and masseter muscles and mandibular movement using the Mandibular Kinesiograph were recorded simultaneously during tapping movement. The usefulness of the 61 items used in this study was evaluated. The results were summarized as follows: 1. In the patient group, a significant correlation between the jaw opening degree during tapping movement and the maximal jaw opening one without pain was recognized. 2. The total muscle activity in the patient group decreased significantly by the insertion of the bite plane. 3. Many subjects of the patient group showed a significant difference between the right and left activity of each muscle. 4. A significant difference between the two groups was found in the duration of muscle activity before and after Silent period, those coefficients of variation and the difference between those durations of the right and left muscle activity. This study suggests that the above factors are very useful parameters for examination and diagnosis of temporomandibular joint dysfunction.
The opaline silica-rich sedimentary rocks of Milos Island, Greece and their behaviour as pozzolanas in the manufacture of cement (2010)

In the Pliocene–Pleistocene succession of Milos Island, Greece, siliceous rocks of biogenic origin (diatomites) occur interbedded with volcanic tuffs. Locally lava sills penetrate the diatomaceous rocks causing their diagenesis. In order to identify the nature of lava and related tuffites and the influence that lava intrusion had on the diatomaceous rocks, X-ray diffraction, scanning electrom microscopy, X-ray fluorescence and light microscopy analyses were performed on representative samples. The original diatomaceous rocks are mainly composed of opal-A in the form of broken diatom frustules and well preserved silicoflagellate skeletons. The affected diatomite beds are characterised as porcelanites containing neoformed opal-CT lepispheres, in expense of opal-A. To utilise the diatomites and porcelanite as pozzolanas, measurements on the Blaine, water demand and compressive strength of cements were carried out. Slightly lower strength was measured in porcelanite cement, due to the higher crystallinity of opal-CT compared to opal-A. However, both rocks improve the pozzolanic cement properties compared to that currently produced, using glassy tuffs.
Low-Cost NOx Reduction Retrofit for Pump Scavenged Compressor Engines (1995)

The Clean Air Act Amendments of 1990 and the resulting individual State Implementation Plans will require many natural gas pipeline operators to install NOx reduction equipment on existing compressor station engines. A program was undertaken to develop lower cost NOx control options for these engines as compared to traditional techniques. The initial work, described in this paper, focused on the development of a low-cost retrofit package for Cooper-Bessemer GMV and GMV-TF pump scavenged integral compressor engines. The retrofit concept relied on highly dilute combustion to achieve low engine-out NOx emission rates. A significant portion of the effort concentrated on low-cost methods for delivering the required air charge and ignition enhancements to achieve reliable and robust combustion. The prototype retrofit kit has been installed on a GMV-6 in gas compressor service. Performance results showed a 70 percent reduction in NOx emission rates without a corresponding increase in HC emission rates.
Magi‐1 scaffolds Na <sub>v</sub> 1‐8 and Slack K <sub>Na</sub> channels in dorsal root ganglion neurons regulating excitability and pain (2019)

Voltage-dependent sodium (Na<sub>V</sub>) 1.8 channels regulate action potential generation in nociceptive neurons, identifying them as putative analgesic targets. Here, we show that Na<sub>V</sub>1.8 channel plasma membrane localization, retention, and stability occur through a direct interaction with the postsynaptic density-95/discs large/zonula occludens-1-and WW domain-containing scaffold protein called membrane-associated guanylate kinase with inverted orientation (Magi)-1. The neurophysiological roles of Magi-1 are largely unknown, but we found that dorsal root ganglion (DRG)-specific knockdown of Magi-1 attenuated thermal nociception and acute inflammatory pain and produced deficits in Na<sub>V</sub>1.8 protein expression. A competing cell-penetrating peptide mimetic derived from the Na<sub>V</sub>1.8 WW binding motif decreased sodium currents, reduced Na<sub>V</sub>1.8 protein expression, and produced hypoexcitability. Remarkably, a phosphorylated variant of the very same peptide caused an opposing increase in Na<sub>V</sub>1.8 surface expression and repetitive firing. Likewise, <i>in vivo</i>, the peptides produced diverging effects on nocifensive behavior. Additionally, we found that Magi-1 bound to sequence like a calcium-activated potassium channel sodium-activated (Slack) potassium channels, demonstrating macrocomplexing with Na<sub>V</sub>1.8 channels. Taken together, these findings emphasize Magi-1 as an essential scaffold for ion transport in DRG neurons and a central player in pain.-Pryce, K. D., Powell, R., Agwa, D., Evely, K. M., Sheehan, G.

Spinal intra-operative three-dimensional navigation with infra-red tool tracking: correlation between clinical and absolute engineering accuracy (2017)

Computer-assisted navigation (CAN) may guide spinal surgeries, reliably reducing screw breach rates. Definitions of screw breach, if reported, vary widely across studies. Absolute quantitative error is theoretically a more precise and generalizable metric of navigation accuracy, but has been computed variably and reported in fewer than 25% of clinical studies of CAN-guided pedicle screw accuracy. We reviewed a prospectively-collected series of 209 pedicle screws placed with CAN guidance to characterize the correlation between clinical pedicle screw accuracy, based on postoperative imaging, and absolute quantitative navigation accuracy. We found that acceptable screw accuracy was achieved for significantly fewer screws based on 2mm grade vs. Heary grade, particularly in the lumbar spine. Inter-rater agreement was good for the Heary classification and moderate for the 2mm grade, significantly greater among radiologists than surgeon raters. Mean absolute translational/angular accuracies were 1.75mm/3.13° and 1.20mm/3.64° in the axial and sagittal planes, respectively. There was no correlation between clinical and absolute navigation accuracy, in part because surgeons appear to compensate for perceived translational navigation error by adjusting screw medialization angle. Future studies of navigation accuracy should therefore report absolute translational and angular errors. Clinical screw grades based on post-operative imaging, if reported, may be more reliable if performed in multiple by radiologist raters.
Peroxidase‐modified carbon paste microelectrode as amperometric FI‐detector for peroxides in partial aqueous media (1996)

Abstract Biosensor characteristics of peroxidase‐lactitol‐modified carbon paste microclectrodes have been evaluated in aqueous and partial aqueous media (H 2 O–10% v./v. CH 3 OH and H 2 O–10% v./v. CH 3 CN), for hydrogen peroxide and 2‐butanone peroxide amperometric detection, using a flow injection system. The activity of the investigated peroxidases (horseradish and fungal peroxidase from Arthromyces ramosus ) was higher for hydrogen peroxide than for 2‐butanone peroxide, irrespective of the solvent composition. For both peroxidases, the microelectrodes' sensitivity, estimated from the slopes of the linear domains as well as calculated from the Eddie‐Hofstee plots decreased in the sequence: H 2 O > H 2 O–10% v./v. CH 3 CN > H 2 O–10% v./v. CH 3 OH. It is suggested that this behavior was due to the difference between the polarity and other physical properties, such as kinematic viscosity and dielectric constant of the nonaqueous solvents.
Morphology of a Cytochrome c-Adsorbed Stearic Acid Monolayer on Brewster Angle Microscopy (1995)

The morphologies of stearic acid and cytochrome c (cyt.c)-adsorbed stearic acid monolayers were investigated by Brewster angle microscopy (BAM) with various molecular areas of stearic acid. With an area of more than 0.38 nm2/molecule, many blight island domains and some bright circles were observed in the BAM image of the stearic acid monolayer. The blight site part became to occupy all the surface with compression, and then became more closely packed with an area of 0.22 nm2/molecule. On the other hand, a different BAM image was obtained for the cyt.c-adsorbed stearic acid monolayer, as follows: (i) a striped pattern was only observed in the presence of cyt.c; (ii) the number of bright circles in the presence of cyt.c was less than that in its absence. Furthermore, when a uniform BAM image was observed for the stearic acid monolayer with cyt.c, the intensity of the absorbance at 409 nm of cyt.c was the highest. By calculating the amount of cyt.c adsorbed on a stearic acid monolayer from the absorbance value, it was shown that cyt.c was most closely packed when an uniform BAM image was observed. These results suggest that the use of BAM and visible absorption spectroscopy together is useful for studying the morphology of a monolayer.
