Small circularly polarized patch antenna (2011)

This paper presents a novel size reduced circularly polarized (CP) patch antenna by introducing a substrate integrated metallic wall structure to provide capacitive and inductive loading to the patch. Pairs of metallic walls are formed by conducting vias and assigned at four corners underneath the patch. To generate circular polarization, a square patch with unbalanced tails is applied. The antenna works at 3.24 GHz. With the presents of the proposed metallic wall structure, the antenna has a considerable size reduction by the capacitive and inductive loading effect. Comparing with a traditional half-wavelength square patch antenna, the proposed CP antenna has achieved 86% size reduction experimentally.
A phase I trial of SD-9427 (progenipoietin) with a multipeptide vaccine for resected metastatic melanoma. (2003)

SD-9427 with a multipeptide vaccine was generally well tolerated, although one patient developed reversible antibody-mediated neutropenia. These data suggest that the majority of patients with resected melanoma mount an antigen-specific immune response against a multipeptide vaccine administered with SD-9427.
Perpendicular magnetic anisotropy of Mn4N films on MgO(001) and SrTiO3(001) substrates (2014)

We grew Mn4N epitaxial thin films capped with Au layers on MgO(001) and SrTiO3(001) substrates by molecular beam epitaxy. Perpendicular magnetic anisotropy (PMA) was confirmed in all the samples at room temperature from the magnetization versus magnetic field curves using superconducting quantum interference device magnetometer. From the ω-2θ x-ray diffraction (XRD) and ϕ-2θχ XRD patterns, the ratios of perpendicular lattice constant c to in-plane lattice constant a, c/a, were found to be about 0.99 for all the samples. These results imply that PMA is attributed to the in-plane tensile strain in the Mn4N films.

Teaching Neuro Images : Apathetic variant of frontotemporal dementia (2011)

A 68-year-old man displayed 3 years of progressive deterioration in behavior/personality. Previously gregarious, he developed reduced social and empathic interactions, diminished (though fluent) spontaneous speech, and indifference to personal hygiene. He denied depression, lacked insight into his predicament, and was not disinhibited, impulsive, or socially inappropriate. Cognitive examination showed reduced vigilance on a continuous-performance task, perseveration on alternating-sequences testing, impaired phonemic greater than semantic fluency, and poor planning and organization. MRI and fluorodeoxyglucose PET revealed bilateral frontal atrophy and prefrontal, insular, and anterior-temporal hypometabolism, respectively (figure). 1 Frontotemporal dementia, apathetic variant, may result from anterior cingulate and dorsolateral prefrontal hypofunction.
Characterization of the Positioning Accuracy and Precision of MEMS Die Servoing Using Model-Based Visual Tracking (2014)

This work deals with an automated micro-assembly of MEMS die holders using a 3D visual servoing approach. Visual positioning which was used is based on eye-to-hand tracking principle. The 3D poses of the MEMS are supplied in a real-time by a 3D (CAD) model-based tracking algorithm. Having executed the visual servoing the accuracy and repeatability of this method was examined. The micro-assembly process was performed and the accuracy calculated according to ISO 9283. The achieved accuracy was 0.345 μm and repeatability was 4.3 μm. The rotation accuracy was less than 0.13°.
Internet of Birds (IoB): Song Based Bird Sensing via Machine Learning in the Cloud : How to sense, identify, classify birds based on their songs? (2020)

How to sense a bird? How to recognize, identify, classify birds? When to involve a "virtual" bird of prey to protect agricultural goods from real birds (game damage)? A machine learning / deep learning (ML/DL), two-level cloud-based sensor network has been implemented to protect agricultural goods from certain bird attacks or attacks by other animals with specific sounds/songs/noises. The background noise will be neglected via the teaching process. The accuracy (lower ratio of both false negative and false positive cases) will be drastically decreased via our two phase - network agile - solution. In the first phase, the sensor module placed in the field decides whether there is any likelihood of a critical bird being there, or there is certainty about no bird being around the sensor. This phase relies on a rather simple pre-filtering that is compatible with the limited resources of the sensor module. Then, if there is a certain likelihood of the sought bird, the song - or at least some sound snippets of it - is sent via a radio link, a gateway, and the Internet to a cloud based software unit that performs ML based reliable recognition. This is the second, much more accurate, much more reliable, however, much more computationally intense phase. Once the bird is detected, some actions can be triggered (e.g., playing a bid of prey song, or firing an alarm) remotely from the cloud.
Polypeptide‐synthetic polymer hybrids, 1. Miscibility of poly(vinyl alcohol) with poly(sodium α,β‐D,L‐aspartate) (1997)

Abstract The present paper describes materials of polypeptide‐commodity polymer hybrids from poly(vinyl alcohol) (PVA) and poly(sodium α,β‐ D , L ‐aspartate) ( 1 ). Miscible blend films of polypeptide 1 and PVA were prepared by the solvent‐cast method from a homogeneous aqueous solution. Differential scanning calorimetry. Fourier transform infrared, and scanning electron microscopy combined with energy dispersive X‐ray spectroscopy (EDX) were used to investigate the blends. It was revealed that 1 and PVA are miscible in a wide range of compositions.
1D Cu(OH)2 Nanomaterial Synthesis Templated in Water Microdroplets (2010)

For many applications, micro- and nanostructured materials show a strong correlation between their geometry and their function. We report here the interfacial precipitation of a copper/alkylamine complex to form Cu(OH)(2) nanofibers in a two-phase system (H(2)O/CH(2)Cl(2)). Their aggregation results in porous microbeads. This mesoscale aggregation is due to the formation of a water-in-oil (W/O) emulsion. The fibers formed at the H(2)O/CH(2)Cl(2) interface adsorb on the water droplet surface leading to spherical networks of Cu(OH)(2) fibers. Our preparation technique is rapid (less than 1 h) and benefits from the simplicity and the tunability of emulsions.To our knowledge, this is the first demonstration of the in situ synthesis of 1D nanostructures that self-assemble at both the surface and the inside of emulsion droplets. We report the successful control over the chemical nature of the synthesized material, its size, and morphology at both the mesoscale (completely hollow versus porous) and the nanoscale (nanoribbons versus nanofibers) by the addition of a short chain alcohol. The transformation of these materials into porous CuO spheres has several potential applications, including a demonstrated sensitive response to visible light (measured photocurrent/dark current ratio of 2.22).
Carrier separation analysis for clarifying leakage mechanism in unstressed and stressed HfAlO/sub x//SiO/sub 2/ stack dielectric layers (2004)

The carrier type involved in the leakage current through HfAlO/sub X//SiO/sub 2/ dielectric layers has been investigated for unstressed and stressed MOSFETs, using the carrier separation method. It is found that the hole current dominates the leakage current in the unstressed HfAlO/sub X//SiO/sub 2/. The dominant carrier in stress-induced leakage current (SILC) is hole, while the electron current is predominant after the soft breakdown (SBD) of the dielectric film. For the SILC condition, the trap generation in the high-k stack occurs both near the conduction band edge of n/sup +/poly-Si and the valence band edge of Si substrate. The defect sites generated in the high-k stack after SBD are located at energies near the conduction band edge of n/sup +/poly-Si.
Prognostic Value of Ishak Fibrosis Stage: Findings From the Hepatitis C Antiviral Long-Term Treatment Against Cirrhosis Trial (2009)

Diabetes and oral disease: implications for health professionals (2012)

"Diabetes and Oral Disease: Implications for Health Professionals" was a one-day conference convened by the Columbia University College of Dental Medicine, the Columbia University College of Physicians and Surgeons, and the New York Academy of Sciences on May 4, 2011 in New York City. The program included an examination of the bidirectional relationship between oral disease and diabetes and the interprofessional working relationships for the care of people who have diabetes. The overall goal of the conference was to promote discussion among the healthcare professions who treat people with diabetes, encourage improved communication and collaboration among them, and, ultimately, improve patient management of the oral and overall effects of diabetes. Attracting over 150 members of the medical and dental professions from eight different countries, the conference included speakers from academia and government and was divided into four sessions. This report summarizes the scientific presentations of the event.

Organic steer production based on dairy breed bull calves - a farm study in Denmark (2003)

The objective of this study was to describe organic steer production on farm level. Six Danish organic farms were part of the registration program including 3 dairy farmers and 3 crop farmers buying dairy breed bull calves from organic dairy farmers. All farmers had a steer production, some of them were recently started and some had an established steer production. The experiment endured 2 years from January 2000 to April 2002. Registrations included liveweight, feed consumption, welfare and slaughter results with special emphasis on the fattening period. Welfare registrations were based on a scheme describing the system as well as the animal during winter when stabled in the barn and during summer on pasture. Registrations were measured on the system as well on the animals. Daily gain on pasture varied from 533 to 823 g and covers grazing on ryegrass/clover pastures as well as marginal grazing areas. On most of the farms steers grazed both kind of pastures. Gains during the stable period varied from 562 to 867 g/day between the farms. Feed consumption per steer per year was 1770 SFU ± 186 based on 4 farms. Feed consumption in summer accounted 0.47 to 0.57 of total feed consumption (DM) per year. Pasture accounts for 0.22 to 0.56 and concentrates for 0.16 to 0.37 of the total dry matter (DM) consumption per year. Management strategies concerning the fattening of steers were different between the 6 farms, as liveweight (458-595 kg) and age (20-25 months) at start of fattening and at slaughter (565-667 kg and 23-28 months) and length of fattening period (2.3-3.4 months) varied. Feeding during the fattening period was based on 1.3 to 4.7 Scandinavian Feed Units (SFU) concentrates per steer per day and silage ad libitum. The total amount of cereals consumed in the fattening period was 100-357 kg/steer. Only few steers were fattened on pasture. It seemed that whole crop silage is preferred to grass silage in the fattening period. Slaughter results show a variation between farms in slaughter percentage from 49.4 to 53.8, carcass conformation from 3.5 to 4.9 and fatness from 2.5 to 3.2. Liveweight at slaughter was the only variable with general effect on carcass conformation on 5 farms (0.6 point on the EUROP-scale with increase in 100 kg liveweight at slaughter). The welfare registration scheme indicates good conditions both in the barn and on pasture, low disease rate and minor problems concerning welfare aspects in organic steer production. It is concluded that great variation between farms concerning management strategies shows the possibilities for improving the production system. Fattening strategy should focus on liveweight at slaughter. Length of fattening period as well as daily gain during the fattening period in the range practiced on the farms seemed to be of minor importance with regard to carcass conformation.
有機塩素剤農薬中毒に関する研究 第1編 血中有機塩素剤農薬の簡易検出法およびその応用 (1973)

According to the statistics by the Ministry of Health on toxications due to drugs for agricultural uses, we have had incidents by organic chloride compounds for many years. In future, there is also a possibility to encounter chronic intoxications by the above compounds. We have relied on solely a close observation on clinical manifestations for its diagnosis. Understandably, there has been no proper treatments established up to now. Therefore, it is a very urgent demand in our community to establish the most reliable method detecting organic chloride substance. The author have tried to devise a simplified method to detect organic chloride substance, as quick as possible in peripheral blood, using an electron capture detector. Its principle was based on gas-chromatography. Results 1) It takes approximately one hour with petroleum-ether to extract organic chlorides in peripheral blood. This is a simplified and speedy method as compared to a conventional way which needs a complicated clean-up. 2) A minimal concentration of organic chlorides to be detected is 0.008ppm for Dieldrin, 0.003ppm Aldrin, 0.02ppm p,p'-DDT and 0.003ppm γ-BHC, indicating a significantly sensitive method. 3) It is feasible to extract various organic chlorides separately by combining several columns in a gas-chromatograph, i.e., 1.5% SE-30, 10% DC-200+15% QF-1 and 1.5% OV-17. The author, thus, has been able to produce an evidence that the above method is extremely useful for diagnosing the intoxication by organic chlorides. Using this method, a part of the dynamics in the intoxicated patients has been also clearified.
Counter-flow Ion Mobility Analysis: Design, Instrumentation, and Characterization (2007)

The quest to achieve high resolution in ion mobility spectrometry (IMS) has continued to challenge scientist and engineers in the field of separation science. The low resolution presently attainable in IMS has continued to negatively impact its utility and acceptance. Until now, efforts to improve the resolution have mainly focused on better instrumentation and detection methods. However, since the resolution of IMS is diffusion limited, it makes sense to address this limitation in order to attain high resolution. This dissertation presents a new IMS technique, which utilizes a high electric field and opposing high gas flow velocity with the aim to improve resolution. This approach essentially reduces the residence time of ions in the analyzer. This new technique is called "counter-flow ion mobility analysis" (CIMA). Theoretical modeling of this new technique predicted that a resolution of over 1000 is possible, which is over one order of magnitude better than that of conventional IMS techniques currently used. A wind tunnel was designed and constructed to produce a plug gas flow profile that is needed for CIMA. The test region of the wind tunnel was used as the CIMA analyzer region and was constructed from power circuit boards, PCBs, (top and bottom walls) and conductive plastic side walls. An inclined electric field was created by applying suitable voltages to multiple electrode traces on the PCBs. This inclined field, when resolved into its x- and y-components, was used to oppose the counter-gas flow and transport the ions to the detector, respectively. The results obtained did not show an improvement over conventional IMS techniques because of a limitation in the voltage that could be applied to the analyzer region. However, the results predict that high resolution is possible if (1) the ratio of the electric fields in the horizontal (x direction) to the vertical (y direction) is within the range of 2--0.5, (2) very high electric field and high gas flow velocities are applied, and (3) wall effects in the counter-flow gas profile are eliminated. While the resolution obtained using the present instrumentation is far from what was predicted, the foundation for ultimately achieving high resolution has been laid. The use of a wind tunnel has made the instrumentation possible. As far as the author knows, this is the first time a wind tunnel has been used in chemical measurement instrumentation. Chapter 5 of this dissertation, reports a method developed for predicting the reduced mobility constants, of chemical compounds. This method uses a purely statistical regression analysis for a wide range of compounds which is different from similar methods that use a neural network. The calculated value for this method was 87.4% when calculated values were plotted against experimental K0 values, which was close to the value for the neural network method (i.e., 88.7%).
A flexible structure for fully scalable motion-compensated 3-D DWT with emphasis on the impact of spatial scalability (2006)

We investigate the implications of the conventional "t+2-D" motion-compensated (MC) three-dimensional (3-D) discrete wavelet/subband transform structure for spatial scalability and propose a novel flexible structure for fully scalable video compression. In this structure, any number of levels of "pretemporal" spatial wavelet decomposition are performed on the original full resolution frames, followed by MC temporal decomposition of the subbands within each spatial resolution level. Further levels of "posttemporal" spatial decomposition may be performed on the spatiotemporal subbands to provide additional levels of spatial scalability and energy compaction. This structure allows us to trade energy compaction against the potential for artifacts at reduced spatial resolutions. More importantly, the structure permits extensive study of the interaction between spatial aliasing, scalability and energy compaction. We show that where the motion model fails, the "t+2-D" structure inevitably produces misaligned spatial aliasing artifacts in reduced resolution sequences. These artifacts can be removed by using pretemporal spatial decomposition. On the other hand, we also show that the "t+2-D" structure necessarily maximizes compression efficiency. We propose different schemes to minimize the loss of compression efficiency associated with pretemporal spatial decomposition.
Magneto-optical Kerr effects of ferromagnetic Ni-gratings (2000)

We report measurements of the magneto-optical Kerr effect (MOKE) on an optical grating of Ni-stripes on Si(111) and a grating of Al-stripes on a Ni thin film. The analysis of the MOKE signal at different orders of diffraction n reveals a change of the Kerr signal amplitude, which is periodic in n having the same periodicity as the total intensity of the diffracted light. For the grating of Ni-stripes we observe a definite change of the shape of the magnetic hysteresis loops also varying systematically with the order of diffraction n.
Computation identifies structural features that govern neuronal firing properties in slowly adapting touch receptors (2014)

Touch is encoded by cutaneous sensory neurons with diverse morphologies and physiological outputs. How neuronal architecture influences response properties is unknown. To elucidate the origin of firing patterns in branched mechanoreceptors, we combined neuroanatomy, electrophysiology and computation to analyze mouse slowly adapting type I (SAI) afferents. These vertebrate touch receptors, which innervate Merkel cells, encode shape and texture. SAI afferents displayed a high degree of variability in touch-evoked firing and peripheral anatomy. The functional consequence of differences in anatomical architecture was tested by constructing network models representing sequential steps of mechanosensory encoding: skin displacement at touch receptors, mechanotransduction and action-potential initiation. A systematic survey of arbor configurations predicted that the arrangement of mechanotransduction sites at heminodes is a key structural feature that accounts in part for an afferent's firing properties. These findings identify an anatomical correlate and plausible mechanism to explain the driver effect first described by Adrian and Zotterman. DOI: http://dx.doi.org/10.7554/eLife.01488.001.
