Electrical and magnetic properties of hole-dopedSr1+xLa1−xFeO4 (1994)

Hole-doped ${\mathrm{Sr}}_{1+\mathit{x}}$${\mathrm{La}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{FeO}}_{4}$ (0\ensuremath{\le}x\ensuremath{\le}0.3) samples were prepared, and electrical transport, magnetic properties and $^{57}\mathrm{Fe}$ M\"ossbauer spectra of the resulting materials were measured. The results were compared with those of hole-doped charge-transfer (CT) insulators. The antiferromagnetic N\'eel temperature decreased from \ensuremath{\sim} 350 to \ensuremath{\sim}150 K on going from x=0 to 0.3, and dc electrical resistivity at room temperature decreased from \ensuremath{\sim}${10}^{3}$ \ensuremath{\Omega} cm for x=0 to \ensuremath{\sim}${10}^{0}$ \ensuremath{\Omega} cm for x=0.3. The heavily doped samples showed semiconducting behavior even for x=0.3. Seebeck voltage measurements demonstrated that all the samples were p-type semiconductors. Although the changes in the magnetic properties upon doping were qualitatively similar to the CT insulators such as (La,Sr${)}_{2}$${\mathrm{CuO}}_{4}$ and (La,Sr${)}_{2}$${\mathrm{NiO}}_{4}$, the changes in the electrical-transport properties upon doping differed from those in the CT insulators. The origin of these differences is discussed with reference to the changes in the electronic structure upon doping.
Accelerated formation of multicellular 3‐D structures by cell‐to‐cell cross‐linking (2007)

The three-dimensional (3-D) arrangement of cells within tissues is integral to their development and function. Advances in stem cell science and regenerative medicine have stimulated interest in the replication of this architecture in vitro. We have developed a versatile method for controlling short-term cell-cell and cell-matrix interactions via a facile cell surface engineering process that enables the rapid formation of specific 3-D interactions for a range of cell types. We demonstrate that chemical modification of cell surfaces and matrix proteins can artificially accelerate the cell adhesion process and confirm the ability to control the formation of multicellular aggregates with defined architectures and heterotypic cell types. Direct comparison with a natural aggregation process seen during differentiation of embryonic stem (ES) cells revealed increased expression of developmental regulatory proteins and a concomitant enhancement of ES cell differentiation. Furthermore, this new methodology has numerous applications in generating layered structures. For example, we demonstrate improved transfer of therapeutic human keratinocytes onto a dermal layer in a skin repair model.
66.3: Invited Paper: Image Quality Improvements in Large‐Screen LC‐TV (2005)

Abstract The image quality improvement on large screen LC‐TV is described. LC‐TV that is achieving a larger screen than CRT has the advantage that 100% brightness for entire screen can be achieved, even by a size that reaches 60 inches. On the other hand, due to its high luminance and large screen size, image quality problems become more visible and thus they should be compensated. As an example of these problems, visible contouring, motion blur, and image compression degradation due to MPEG compression and their compensation algorisms are described in this paper.

Forms2Dialog: Automatic dialog generation for Web tasks (2014)

Today, many common tasks (e.g. booking flights, ordering food) can be done by filling out web forms. Automatic processing of Web forms to support interactive speech input is useful for numerous reasons, including ease of use for mobile device users and accessibility for people with visual or print disabilities. In this paper, we propose an automated method to process web forms and convert them into dialog flows for spoken interaction. First we identify relevant information for each form element (including element type, label, values and help messages) and key relationships between form elements (including ordering and dependencies). We then generate two types of dialog flow for each Web form. Experimental results show that the method generates efficient and informative dialog flows for web tasks, a key step for building virtual assistants. An Android application has been realized as a use case of the generated dialog flows.
One Dimensional Photonic Crystals Using Ultrahigh Refractive Index Chalcogenide Hybrid Inorganic/Organic Polymers (2018)

We report on the fabrication of wholly polymeric one-dimensional (1-D) photonic crystals (i.e., Bragg reflectors, Bragg mirrors) via solution processing for use in the near (NIR) and the short wave (SWIR) infrared spectrum (1-2 μm) with very high reflectance (<i>R</i> ∼ 90-97%). Facile fabrication of these highly reflective films was enabled by direct access to solution processable, ultrahigh refractive index polymers, termed, Chalcogenide Hybrid Inorganic/Organic Polymers (CHIPs). The high refractive index (<i>n</i>) of CHIPs materials (<i>n</i> = 1.75-2.10) allowed for the production of narrow band IR Bragg reflectors with high refractive index contrast (Δ<i>n</i> ∼ 0.5) when fabricated with low <i>n</i> polymers, such as cellulose acetate (<i>n</i> = 1.47). This is the highest refractive index contrast (Δ<i>n</i> ∼ 0.5) demonstrated for an all-polymeric Bragg mirror which directly enabled high reflectivity from films with 22 layers or less. Facile access to modular, thin, highly reflective films from inexpensive CHIPs materials offers a new route to IR Bragg reflectors and other reflective coatings with potential applications for IR photonics, commercial sensing, and LIDAR applications.
Accelerating light with metasurfaces (2018)

It has been recently shown that especially engineered light beams have the remarkable ability to propagate along curved trajectories in vacuum. Current methods for generating accelerating beams use phase modulators and lenses leading to length scales on the order of tens of centimeters or larger. This poses constraints and severely limits their applicability inside materials. Here, we accelerate light inside glass using a metasurface consisting of plasmonic nanoantennas. Highly-bending beams with radii of curvature on the order of a hundred microns were generated, and the imaged intensities agree well with theory. Our approach for generating accelerating beams allows for their integration into on-chip photonic systems.
Induction of apoptosis (2013)

Apoptosis, or programmed cell death, is an evolutionary conserved genetic process of cellular suicide, which plays a crucial role in sculpting the developing organism and in “pruning” billions of unwanted, unneeded, or damaged cells every day during adult life (1). Aberrations of apoptosis leading to abnormal cell viability or excess cell death contribute to the pathogenesis of human diseases (2). However, these alterations are particularly important in cancer, where they impact virtually every facet of the disease, from onset to progression to treatment (3). As our knowledge of apoptotic pathways has dramatically increased over the past decade, so have the opportunities to harness this powerful cellular suicidal program for novel molecular cancer therapeutics (4).
Poly[aquahexabenzimidazoleocta-μ-cyanido-octacyanidotricopper(II)ditungstate(V)] (2010)

In the polymeric title compound, [Cu(3)W(2)(CN)(16)(C(7)H(6)N(2))(6)(H(2)O)](n), the coordination geometry of the W(V) atom is eight-coordinate dodeca-hedral, where four CN groups of [W(CN)(8)] are bridged to Cu(II) ions, and the other four CN groups are not bridged. The coordination geometries of the Cu(II) ions are five-coordinate pseudo-square-based pyramidal. There are two distinct Cu sites, which build and link the cyanido-bridged Cu-W ladder chains. Successive connections lead to the formation of a two-dimensional network. The H atoms of a coordinated water molecule and the imino groups form hydrogen bonds to the N atoms of non-bridged CN groups.
Distribution and diversity of root-lesion nematodes (Pratylenchus spp.) associated with Ammophila arenaria in coastal dunes of Western Europe (2007)

Abstract The distribution and diversity of Pratylenchus species associated with Ammophila arenaria was investigated in its natural range of distribution. Twelve localities with vigorous stands of A. arenaria along the European Atlantic and Mediterranean coasts were sampled. The populations were identified based on morphology and morphometrics, and further characterised based on sequences of the rDNA D2D3 region. Pratylenchus spp. were present in all of the sampled sites. A total of 19 populations were detected belonging to Pratylenchus dunensis, P. brzeskii, P. pratensis or P. penetrans. Pratylenchus dunensis was widely distributed from Blakeney Point (UK) to Comporta (Portugal). Pratylenchus brzeskii was found in South European localities along the Atlantic coast and also in the Mediterranean region. Pratylenchus pratensis was found associated with A. arenaria for the first time and occurred at different locations along the Atlantic coast. Pratylenchus penetrans was only detected in Biarritz (France). The P. dunensis populations from the south west Iberian Peninsula differed from the original P. dunensis description and showed two incisures on the lip region instead of one. Pratylenchus brzeskii populations did not vary morphologically from the original descriptions; however, the range of their morphometrical characters was wider than that of the type population. The D2D3 rDNA region revealed large interspecific and low intraspecific variation, supporting the morphological identification. The phylogenetic relationships of the populations with respect to other species of the genus were inferred from partial sequences of the rDNA and positioned P. dunensis within the same group as P. convallariae, P. penetrans and P. fallax.

Poly(Aryl ether‐phenylquinoxaline)s: Self‐polymerization of an A—B monomer via quinoxaline‐activated ether synthesis (1992)

Abstract A new A—B monomer, 2‐(4‐hydroxyphenyl)‐3‐phenyl‐6‐fluoroquinoxaline ( 1 ), which contains both a quinoxaline‐activated fluoro group and a phenol group was prepared and it's self‐polymerization studied. Compound 1 was prepared either by condensation of 3,4‐diaminofluorobenzene with 4‐hydroxybenzil, or condensation/demethylation with 4‐methoxybenzil in a one pot procedure. The polymerization of 1 was carried out in NMP in the presence of potassium carbonate at 180–190°C, analogous to previous examples of quinoxaline‐activated polyether synthesis. A new poly(aryl ether‐phenylquinoxaline) ( 2 ) was synthesized by this procedure, which was processable from N ‐methylpyrrolidone, displayed a T g of 255°C and a polymer decomposition temperature of 450°C. The mechanistic implications of quinoxaline activated fluoro‐displacement using an A—B monomer are discussed.
Opportunities in Multimaterial Fibers From nanofabrication to chemical reactions to novel device architectures (2013)

Multimaterial fiber devices share the basic functional attributes of their traditional electronic counterparts, yet are fabricated from metals, insulators and semiconductors using scalable preform-to-fiber processing methods, yielding kilometers of functional fibers. New discoveries extend the field of opportunities to nanofabrication and chemistry.
Physiological Profiles of Episodic Progesterone Release During the Midluteal Phase of the Human Menstrual Cycle: Analysis of Circadian and Ultradian Rhythms, Discrete Pulse Properties, and Correlations With Simultaneous Luteinizing Hormone Release* (1988)

To define the physiological relationships between episodic progesterone and LH release, we measured serum progesterone and LH concentrations in blood sampled at 10-min intervals for 24 h in seven young women in the midluteal phase of the menstrual cycle. The resultant time series were assessed further by Fourier transformation, Cluster analysis, and cross-correlation analysis with autoregressive modeling. These techniques permitted an examination of circadian rhythms, discrete (ultradian) pulse properties, and simultaneous or lagged correlations between progesterone and LH release. We found the following. 1) Both serum LH and progesterone concentrations had significant circadian periodicities, with similar acrophases (times of maximal nyctohemeral values). LH and progesterone also manifested multiple ultradian rhythms of similar periodicities (range, 48-241 min). 2) Discrete serum progesterone peaks occurred at a mean interpulse interval of 118 +/- 12 (+/- SE) min, had durations of 92 +/- 12 min, and had incremental amplitudes of 4.3 +/- 0.9 ng/mL (14 +/- 3 nmol/L). The frequency and duration characteristics of the progesterone and LH peaks were not significantly different, but progesterone fractional peak amplitudes were one quarter those of LH pulses. 3) Fractional progesterone peak amplitudes in the seven women correlated inversely (r = -0.811) with 24-h mean LH concentrations, suggesting a negative feedback relationship between progesterone and LH release. 4) LH and progesterone interpulse intervals both exhibited significant nyctohemeral variations, with diurnal amplitudes of 73 +/- 12 min for LH and 43 +/- 8.9 min for progesterone (P less than 0.01). 5) Significant positive cross-correlations existed in all seven women between serum LH and progesterone concentrations considered simultaneously and at progesterone time lags of 10-50 min. By autoregressive modeling, the later (20-50 min) cross-correlations could be accounted for by sustained autocorrelations in the individual progesterone and LH time series and significant cross-correlations between LH and simultaneous progesterone concentrations and between LH and 10-min lagged progesterone concentrations. We conclude that progesterone release occurs in a periodic (circadian and ultradian) fashion as well as in a discrete (episodic or pulsatile) mode. Moreover, both positive and negative feedback relationships operate to coordinate LH and progesterone secretion in the midluteal phase of the human menstrual cycle.
MIL-100(Fe)를 함유한 혼합기질막(mixed-matrix membranes, MMMs)의제조 및 기체 투과 특성 연구 (2013)

본 연구에서는 metal organic frameworks (MOFs)의 한 종류인 MIL-100(Fe)을 이용하여 혼합기질막(mixed matrix membranes, MMMs)을 제조하였다. MIL-100(Fe)의 함량을 고분자 대비 0~30 wt%까지 변화시키면서 첨가된 MOF의 함량에 따른 기체의 투과 특성을 살펴보았다. $H_2$ , $CO_2$ , $O_2$ , $N_2$ , $CH_4$ 의 기체 투과도는 MIL-100(Fe) 첨가량이 증가함에 따라 투과도가 증가하는 경향을 보여주었으며, 상대적으로 큰 입자크기를 가진 $SF_6$ 의 투과도는 MIL-100(Fe)의 첨가량이 증가함에 따라 투과도가 감소하였다. 이상 선택도는 $N_2/SF_6$ 의 경우 폴리이미드막 대비 약 40% 증가하였으며, 이를 통해 $N_2/SF_6$ 분리에 적합한 분리막임을 확인할 수 있었다. 【Mixed-matrix membranes (MMMs) containing MIL-100(Fe), a MOF type, were fabricated in this study. MMMs up to 30 wt% MOF loading were prepared, and their gas permeabilities were tested. $H_2$ , $CO_2$ , $O_2$ , $N_2$ , and $CH_4$ gas permeabilities increased with the MOF loading, while $SF_6$ , the largest kinetic diameter in this study, exhibited reduction of gas permeability with the loading. Ideal gas selectivity of $N_2/SF_6$ improved by 40% as compared with pure polyimide membrane, suggesting the proposed MMMs were suitable for $N_2/SF_6$ separation.】
Stage and size using magnetic resonance imaging and endosonography in neoadjuvantly-treated rectal cancer (2013)

AIM: To assess the stage and size of rectal tumours using 1.5 Tesla (1.5T) magnetic resonance imaging (MRI) and three-dimensional (3D) endosonography (ERUS). METHODS: In this study, patients were recruited in a phaseⅠ/Ⅱ trial of neoadjuvant chemotherapy for biopsy-proven rectal cancer planned for surgical resection with or without preoperative radiotherapy. The feasibility and accuracy of 1.5T MRI and 3D ERUS were compared with the histopathology of the fixed surgical specimen (pathology) to determine the stage and size of the rectal cancer before and after neoadjuvant chemotherapy. A Philips Intera 1.5T with a cardiac 5-channel synergy surface coil was used for the MRI, and a B-K Medical Falcon 2101 EXL 3D-Probe was used at 13 MHz for the ERUS. Our hypothesis was that the staging accuracy would be the same when using MRI, ERUS and a combination of MRI and ERUS. For the combination, MRI was chosen for the assessment of the lymph nodes, and ERUS was chosen for the assessment of perirectal tissue penetration. The stage was dichotomised into stageⅠ and stage Ⅱ or greater. The size was measured as the supero-inferior length and the maximal transaxial area of the tumour. RESULTS: The staging feasibility was 37 of 37 for the MRI and 29 of 36 for the ERUS, with stenosis as a limiting factor. Complete sets of investigations were available in 18 patients for size and 23 patients for stage. The stage accuracy by MRI, ERUS and the combination of MRI and ERUS was 0.65, 0.70 and 0.74, respectively, before chemotherapy and 0.65, 0.78 and 0.83, respectively, after chemotherapy. The improvement of the post-chemotherapy staging using the combination of MRI and ERUS compared with the staging using MRI alone was significant (P = 0.046). The post-chemotherapy understaging frequency by MRI, ERUS and the combination of MRI and ERUS was 0.18, 0.14 and 0.045, respectively, and these differences were non-significant. The measurements of the supero-inferior length by ERUS compared with MRI were within 1.96 standard deviations of
Description and Test Results from a Supercritical CO2 Brayton Cycle Development Program (2009)

The Supercritical CO2 Brayton cycle (S-CO2) can potentially offer more efficient and compact power conversion systems for advanced nuclear reactors, solar, or fossil fuel systems. The DOE Office of Nuclear Energy, Knolls Atomic Power Laboratory, and Sandia National Labs are investigating this cycle in a phased development program because it has the potential for high efficiency (in the temperature range from 400 °C to 750 °C), is very compact making it transportable, and may reduce capital costs due to the very compact turbomachinery. This paper describes resent test results from a supercritical CO2 closed Brayton cycle test loop. Sandia manufactured the loop through its contractor Barber Nichols Inc. The paper describes experimental test measurements of the main compressor performance map, the operational behavior of the supercritical loop at the critical point and below the critical point, and it illustrates the approach to break-even power production at very low turbine inlet temperatures (60 °C / 140 °F) using 78 kW of heater power.
Worst-case Throughput Analysis for Parametric Rate and Parametric Actor Execution Time Scenario-Aware Dataflow Graphs (2014)

Scenario-aware dataflow (SADF) is a prominent tool for modeling and analysis of dynamic embedded dataflow applications. In SADF the application is represented as a finite collection of synchronous dataflow (SDF) graphs, each of which represents one possible application behaviour or scenario. A finite state machine (FSM) specifies the possible orders of scenario occurrences. The SADF model renders the tightest possible performance guarantees, but is limited by its finiteness. This means that from a practical point of view, it can only handle dynamic dataflow applications that are characterized by a reasonably sized set of possible behaviours or scenarios. In this paper we remove this limitation for a class of SADF graphs by means of SADF model parametrization in terms of graph port rates and actor execution times. First, we formally define the semantics of the model relevant for throughput analysis based on (max,+) linear system theory and (max,+) automata. Second, by generalizing some of the existing results, we give the algorithms for worst-case throughput analysis of parametric rate and parametric actor execution time acyclic SADF graphs with a fully connected, possibly infinite state transition system. Third, we demonstrate our approach on a few realistic applications from digital signal processing (DSP) domain mapped onto an embedded multi-processor architecture.

Cabergoline in the Treatment of Hyperprolactinemia: A Study in 455 Patients (2000)

Many hyperprolactinemic patients do not tolerate bromocriptine or other dopamine agonists and, even if they do, often must take them two or three times each day. Cabergoline is a long-lasting dopamine agonist whose action lasts up to 2 weeks after a single dose so that it may be taken once or twice a week. This study evaluated cabergoline in 353 women and 102 men with pathologic hyperprolactinemia. Roughly 40 percent of the group had a microadenoma, and the same proportion had a macroadenoma. No cause was evident in 16 percent of cases. Of 292 patients who previously had received bromocriptine, 140 were intolerant and 58 were resistant to the drug. The median baseline serum prolactin was 124 μg/liter. Cabergoline therapy usually began at a dose of 0.25 or 0.5 mg twice weekly, and the dose was adjusted at 2- to 3-month intervals as needed to consistently reduce the prolactin level. Patients then were followed up every 4 to 6 months. Menstrual function became normal during cabergoline therapy in 89 percent of the women evaluated, several of whom became pregnant and delivered healthy children. The visual fields became normal in 70 percent of 47 patients. Migraine symptoms lessened significantly in 72 percent of 71 patients. Prolactin levels became normal in 86 percent of all patients and decreased by 75 percent or more in more than half of the others. The median lowest serum prolactin level, achieved in 8 months on average, was 5.6 μg/liter. The tumor shrank to some degree in two thirds of patients. At the end of follow-up, the median dose of cabergoline was 0.5 mg/week. Minor side effects were reported by 8.5 percent of patients, and major or persistent symptoms were reported by 4 percent. Headache and postural hypotension were the most common adverse effects. Of the 14 patients who withdrew because of intolerance, 12 had also failed to tolerate bromocriptine. Only 9 percent of bromocriptine-intolerant patients were also intolerant of cabergoline. Patients harboring a microprolactinoma required lower doses and were more likely than those with macroadenomas to achieve a normal serum prolactin level. The baseline and lowest serum prolactin levels correlated weakly but significantly. In more than two thirds of patients who had been resistant to bromocriptine, control was achieved with cabergoline. This large-scale study affirms the effectiveness and tolerance of cabergoline when used to treat pathologic hyperprolactinemia. J Clin Endocrinol Metab 1999;84:2518–2522
