NAREOR: The Narrative Reordering Problem (2022)

Many implicit inferences exist in text depending on how it is structured that can critically impact the text's interpretation and meaning. One such structural aspect present in text with chronology is the order of its presentation. For narratives or stories, this is known as the narrative order. Reordering a narrative can impact the temporal, causal, event-based, and other inferences readers draw from it, which in turn can have strong effects both on its interpretation and interestingness. In this paper, we propose and investigate the task of Narrative Reordering (NAREOR) which involves rewriting a given story in a different narrative order while preserving its plot. We present a dataset, NAREORC, with human rewritings of stories within ROCStories in non-linear orders, and conduct a detailed analysis of it. Further, we propose novel task-specific training methods with suitable evaluation metrics. We perform experiments on NAREORC using state-of-the-art models such as BART and T5 and conduct extensive automatic and human evaluations. We demonstrate that although our models can perform decently, NAREOR is a challenging task with potential for further exploration. We also investigate two applications of NAREOR: generation of more interesting variations of stories and serving as adversarial sets for temporal/event-related tasks, besides discussing other prospective ones, such as for pedagogical setups related to language skills like essay writing and applications to medicine involving clinical narratives.
A new germanium based linker for solid phase synthesis of aromatic compounds (1999)

An efficient three-step synthesis of germyl linker precursor 4 is described which enables a simple two step immobilisation of lithiated aromatics to Argogel™ polymer; cleavage from the polymer support via ipso-degermylation with TFA, ICl, Br2 and NCS provides protio-, iodo-, bromo- and chloro- aryls, respectively.
6.4: Photoemission images of cesium coated p- and n-type GaN (2010)

We report photoemission images of a GaN p-n junction patterned and etched to reveal both n-type and p-type regions. Immediately following Cs deposition at low temperature, the n-type areas produced more emission current than did the p-type areas and required only low energy (3 eV) photons to do so. After heating to 375°C the p-type areas became dominant when illuminated with high energy photons (4.8 eV), however the n-type areas continue to dominate when the specimen is illuminated with 3 eV photons. After further heating to 423°C portions of the Cs-coated n-type areas continue to produce emission from 3 eV photons. This behavior can be interpreted as the result of the formation of a surface state due to Cs interacting with the n-type areas, and photoemission directly from the Cs-induced state into vacuum. If this model is correct, it implies that the emission is relatively prompt, since there is no transport in the bulk material.
Towards Dynamic Master Determination in MEMS-based Micro-Scanning LiDAR Systems (2021)

Automated driving has been expected for decades. The first systems, which at least partially automate the vehicle, have been installed in higher priced vehicles for several years. In the near future, however, many more competencies are to be transferred to the systems and the vehicle will thus be fully automated. Such systems receive their data from various sensor systems such as Light Detection And Ranging (LiDAR). Therefore, it is essential that this information is transmitted correctly and reliably to the environmental perception system. In order to ensure this, redundancy of sensors is a key factor in addition to diversity. For example, multiple, independently controlled MEMS-based LiDAR systems can be operated synchronously. This requires the selection of a Master system which can be reliably followed by all Slave systems. In this publication, an architecture for MEMS-based Micro-Scanning LiDAR systems is proposed to determine the appropriate system as Master. The architecture has been implemented in an FPGA prototyping platform to demonstrate its feasibility and evaluate its performance.
Integrated circuits for a real-time large-vocabulary continuous speech recognition system (1991)

The architecture and implementation of a word processing subsystem for a real-time speech recognition system using hidden Markov models are described. The bottleneck of this system, which is the acquisition of data, is demonstrated, and an architecture that speeds up this bottleneck using on-chip dual-ported cache memories is presented. The architecture is described in a textual form, and the layout data were completely automatically generated. The chips have been fabricated through MOSIS using a 2- mu m CMOS n-well technology. The functionality of the processors was successfully tested using the scan-path test methodology. The clock rate for the scan-path test was 5 MHz to guarantee proper operation of the circuits for this clock rate. All the processors were first time working silicon.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Compositional and microstructural profiles across Nb/sub 3/Sn filaments produced by different fabrication methods (2001)

The next generation of high field magnets for fusion and accelerator applications requires the development of Nb/sub 3/Sn strands with significantly higher critical current densities. Our recent work has shown that when the specific pinning force is normalized to the grain boundary density (the primary pinning site in this material), a strong increase in pinning force is observed for high Sn content strand, suggesting a strong compositional dependency for pinning in this material. In this study we use advanced FESEM techniques to quantify the compositional and microstructural variations to a sub-100 nm level. A stepped compositional and microstructural variation was observed across bronze-processed Nb/sub 3/Sn filaments with sharp interfaces for both Cu(Sn)-Nb/sub 3/Sn and Nb/sub 3/Sn-Nb. Microstructural variation was observed on the scale of the original filaments in high Sn, MJR but not across the coalesced filament mass. A very high microstructural uniformity was observed in a PIT monofilament. Thus a major influence of Sn appears to be exerted through its influence on the composition gradient.
Suppressor cell activity in tumor-bearing mice. II. Inhibition of DNA synthesis and DNA polymerases by TBH splenic suppressor cells. (1978)

Spleen cells from fibrosarcoma-bearing mice elaborated a factor of 30 to 50,000 daltons in m.w. that was capable of inhibiting DNA synthesis and DNA polymerase activities of mitogen-stimulated lymphocytes plus unrelated cell types. The cells responsible for producing these factors were characterized as anti-Thy 1 serum- and hydrocortisone-sensitive mildly nylon wool adherent spleen cells (suggesting a suppressor T cell). Both DNA polymerases alpha (α) and beta (β) were significantly inhibited by prepared supernatants from cultures of tumor-bearing host (TBH) spleen cells. DNA polymerase polymerase (IDP). Basal levels of TBH lymphocyte DNA synthesis and polymerase α activity were always higher than their normal counterparts; however, upon mitogen stimulation this was reversed. Normal animal spleen cell DNA polymerase α activity exhibited a direct correlation with mitogen-induced DNA synthesis. In the presence of mitogen, normal spleen cells demonstrated a significant increase in DNA synthesis with a corresponding increase in DNA polymerase α activity, whereas TBH spleen cells upon mitogen stimulation resulted in a concomitant decrease in DNA synthesis and polymerase activity. Inhibition kinetics revealed that IDP was not a competitive inhibitor of DNA polymerase α and did not bind directly to the DNA template in the absence of polymerase. The kinetics imply the production of an enzyme-substrate-inhibitor complex which cannot undergo further reaction to yield a normal product. The data suggest that substances elaborated by tumor-induced suppressor cells operate at a molecular site of DNA polymerases resulting in inhibited cellular proliferation.
New S-Adenosyl-l-methionine Analogues: Synthesis and Reactivity Studies (2009)

Two new and complementary synthetic strategies for 5'-N-chloroethylamino-5'-deoxyadenosines are presented. Additionally, the reaction kinetics of their conversion into aziridines under typical enzyme assay conditions is reported using time-resolved NMR spectroscopy. A stable photocaged derivative of 5'-N-chloroethylamino-5'-deoxyadenosine has also been synthesized, and its stability and activation in aqueous solution at physiological pH have been examined.
Simulation of Smart Environments (2007)

Smart environments are pervasive systems that comprise integrable net-aware devices. This way, intelligent services can offer complex functionalities across multiple devices. Smart home environments, also called eHomes, constitute already an important research area. However, to build a real elome is associated with high effort and financial costs. In this paper, we describe our software tool eHomeSimulator that allows us to simulate different smart environments. Thus, we can abstract from creating buildings and developing or purchasing devices. Instead, we can use the eHomeSimulator to research on software engineering aspects of eHomes, such as service development, specification, composition, deployment, and personalization.
Comparison of Channel Catfish Age Estimates and Resulting Population Demographics Using Two Common Structures (2010)

Abstract Sagittal otoliths and the articulating process of the pectoral spine have both been validated as accurate techniques for estimating the age of channel catfish Ictalurus punctatus (≤age 4). However, there is limited information on the relative precision of estimates from these two structures. Thus, we analyzed the precision of age estimates derived from otoliths and the articulating process of the pectoral spine and compared the dynamic processes (recruitment, growth, and mortality) resulting from those estimates. Aging structures were removed from 110 channel catfish captured from the Wabash River (river kilometers 550–9.6) via day–time electrofishing. The age estimation methodologies were similar to those described in previous studies. Agreement between the ages derived from the two structures was high; the average percent error was 8.4%, the coefficient of variation was 11.4, and the slope of the age bias plots did not differ from 1, indicating similar age assignments between structures. The corresponding recruitment patterns, von Bertalanffy growth models, and mortality rates did not differ between the aging structures. We conclude that the articulating process of the pectoral spine provides age assignments similar to those of otoliths and that the dynamic processes do not differ between structures. Further, based on the results of this study, the articulating process of the pectoral spine provides a suitable alternative to otoliths and has the advantage that channel catfish do not have to be sacrificed.

Phosphorylation-regulated Inhibition of the Gz GTPase-activating Protein Activity of RGS Proteins by Synapsin I (2003)

Synapsins are neuronal proteins that bind and cluster synaptic vesicles in the presynaptic space, presumably by anchoring to actin filaments, but specific regulatory functions of the synapsins are unknown. We found that a sub-population of brain synapsin Ia, a splice variant of one of three synapsin isoforms, inhibits the GTPase-activating protein (GAP) activity of several RGS proteins. Inhibition is highly selective for Galphaz, a member of the Gi family that is found in neurons, platelets, adrenal chromaffin cells, and a few other neurosecretory cells. Gz has been indirectly implicated in the regulation of secretion. Synapsin Ia constitutes a major fraction of the total GAP-inhibitory activity in brain, and its inhibitory activity is absent from the brains of synapsin I(-/-)/II(-/-) mice. Inhibition depends on the cationic D/E domain of synapsin. Phosphorylation of synapsin Ia at serine 9 by either cyclic AMP-dependent protein kinase or p21-activated protein kinase (PAK1) attenuates its potency as a GAP inhibitor more than 7-fold. Synapsin can thus act as a phosphorylation-modulated mediator of feedback regulation of Gz signaling by the synaptic machinery.
Using approximate dynamic programming to optimize admission control in cloud computing environment (2011)

In this work, we optimize the admission policy of application deployment requests submitted to data centers. Data centers are typically comprised of many physical servers. However, their resources are limited, and occasionally demand can be higher than what the system can handle, resulting with lost opportunities. Since different requests typically have different revenue margins and resource requirements, the decision whether to admit a deployment, made on time of submission, is not trivial. We use the Markov Decision Process (MDP) framework to model this problem, and draw upon the Approximate Dynamic Programming (ADP) paradigm to devise optimized admission policies. We resort to approximate methods because typical data centers are too large to solve by standard methods. We show that our algorithms achieve substantial revenue improvements, and they are scalable to large centers.
Using Fourier Transform near Infrared Spectroscopy to Estimate the Nutritional Value in Whole and Milled Naked Oats (2014)

Naked oat is an important grain cereal that originated in, and is cultivated mostly in, China. Naked oat grain has a good processing performance because it is hulless. Its products are important sources of good nutritional protein, dietary fibre, unsaturated fatty acid and polyphenol, all of which have demonstrable benefits for human health. To select the appropriate industry material and develop genotypes with a high nutrient content more efficiently, a fast screening method is needed. In the present study, calibration models were developed from Fourier transform near infrared (FT-NIR) spectra of whole grain and milled grain samples for the estimation of protein, starch, lipid, β-glucan and avenanthramides content in naked oats from an initial set. The optimised models of protein, starch, lipid, β-glucan and avenanthramides in whole grain/milled samples indicated coefficients of determination ( R 2 ) of 0.98/0.98, 0.97/0.98, 0.97/0.97, 0.98/0.98 and 0.90/0.90 and root mean square errors of cross-validation of 0.40/0.35%, 0.59/0.52%, 0.27/0.24%, 0.09/0.06% and 60.4/59.2 mg kg −1 . Test validations yielded root mean square errors of prediction of 0.46/0.40%, 0.68/0.63%, 0.26/0.26%, 0.10/0.09% and 47.7/46.3 mg kg −1 with residual predictive deviations of 5.38/6.30, 5.07/5.15, 6.06/6.24, 5.13/6.17 and 3.37/3.56. These findings showed that FT-NIR could be used as a rapid and accurate method for selecting higher-quality naked oats in a breeding programme as well as for quality control by the food industry.
Suzaku Observation of the Metallicity in the Interstellar Medium of NGC 4258 (2009)

The Suzaku X-ray satellite observed the nearby spiral galaxy NGC 4258 for a total good exposure time of 100 ks. We present an analysis of the Suzaku XIS data, in which we confirm that the 0.5--2 keV spectra of the interstellar medium (ISM) are well-represented by a two-temperature model. The cool and hot ISM temperatures are 0.23+-0.02 and 0.59 +-0.01 keV, respectively. Suzaku's excellent spectral sensitivity enables us to measure the metal abundances of O, Ne, Mg, Si and Fe of the ISM for the first time. The resultant abundance pattern of O, Mg, Si, and Fe is consistent with that of the new solar abundance table of Lodders (2003), rather than Anders &amp; Grevesse (1989). This suggests that the metal enrichment processes of NGC 4258 and of our Galaxy are similar.
[Clinical and pharmacokinetic study of ceftriaxone in the treatment of 14 episodes of ascitic fluid infection]. (1988)

A clinical study and dosages of ceftriaxone were performed during the treatment of 14 ascitic fluid infections. Fourteen cases of ascitic fluid infection were treated with ceftriaxone at doses of 2 grams daily. The isolation of the causative organisms was obtained in 11 out of 14 cases by systematic culture of the ascitic fluid in hemoculture bottles with aerobic and anaerobic medium. Of 11 evaluable infectious episodes ten were cured. Ceftriaxone diffuses rapidly in the ascitic fluid because, within the first hour; mean concentrations were already of 18.6 micrograms/ml largely exceeding the usual MIC for these organisms. A good tolerance for the drug, the well spaced rythm of infections preventing unnecessary parenteral treatment in cirrhotic patients, and its effectiveness against Enterobacteriaceae justify its choice in the treatment of ascitic fluid infections with sensitive organism.
Generalised Viterbi algorithm for trellis codedsignals transmitted through broadband wireless channels (2000)

A receiver structure is proposed for trellis coded signals transmitted through broadband wireless channels based on the generalised Viterbi algorithm (GVA). Simulation results show that the proposed receiver structure is suitable for high bit rate wireless applications and gives close to optimal performances with reasonable complexity.
Changes in the expression of prostaglandin family members in bovine corpus luteum during the estrous cycle and pregnancy (2018)

The aim of this study was to characterize certain prostaglandin family members in the bovine corpus luteum (CL) during the estrous cycle and pregnancy. The CL tissue was assigned to the stages 1-2, 3-4, 5-7, 8-12, 13-16 and >18 days (after regression) of the estrous cycle and 1-2, 3-4, 6-7, and >8 months of pregnancy. In these samples, we investigated prostaglandin F2alpha (PTGF), prostaglandin E2 (PTGE), their receptors (PTGFR, PTGER2, and PTGER4), cyclooxygenase 2 (COX-2), PTGF synthase (PTGFS), and PTGE synthase (PTGES). The expression of messenger RNA (mRNA) was measured by reverse transcription quantitative polymerase chain reaction, hormones by enzyme immunoassay, and localization by immunohistochemistry. The mRNA expression of COX-2, PTGFS, and PTGES in CL during the early-luteal phase was high followed by a continuous and significant downregulation afterward, as well as during all phases of pregnancy. The concentration of PTGF in CL tissue was high during the early-luteal phase, decreased significantly in the mid-luteal phase, and increased again afterward. In contrast, the concentration of PTGE increased significantly during the late-luteal phase followed by a decrease during regression. The PTGE level increased again during late pregnancy. Immunohistochemically, the large granulose-luteal cells show strong staining for COX-2 and PTGES during the early-luteal stage followed by lower activity afterward. During pregnancy, most of the luteal cells were only weakly positive or negative. In conclusion, our results indicate that the examined prostaglandin family members are involved in the local mechanisms that regulate luteal function, specifically during CL formation, function, and regression and during pregnancy in the cow.

An Improved MDS Condition of Blaum-Bruck-Vardy Codes (2018)

Binary maximum distance separable (MDS) array codes play an important role in storage systems. The EVENODD code is a typical binary MDS array code with two parity columns and the Blaum-Bruck-Vardy (BBV) code with more parity columns is an extension of it. It has been shown that when the parameter p is large enough, the BBV code is always MDS. A sufficient MDS condition of the BBV code with more than eight parity columns was proposed before; however, the MDS condition is not tight. In this paper, we improve the MDS condition and present a tighter MDS condition.

Fiber design considerations for 40 Gb/s systems (2002)

In this paper, we review the fundamental advantages and drawbacks of 40-Gb/s systems from a fiber manufacturer's perspective. Based on modeling, experimental results, and fundamental understanding, we correlate the fiber design parameters with the expected performance of long-haul systems operating at 40 Gb/s. Nonlinear penalties, dispersion tolerances, modulation formats, polarization-mode dispersion, and Raman amplification are covered. We also present the fiber features required for both metro and submarine networks at this specific data rate.
Polarization preservation gate-a tool for optical mammography (1996)

Summary form only given. We demonstrate that light propagating through tissue, within a time gate, retains its polarization to a different degree depending on the type of tissue. This observation provides a way to improve optical imaging in turbid media. The polarization-preserving photons belong to the group of early arriving image-carrying photons.
MIL-M-38510/470 test vectors: Fault detection efficiency measurement via hardware fault simulation (1980)

The stuck fault detection efficiency of the test vectors developed for the MIL-M-38510/470 NASA was measured using a hardware stuck fault simulator for the 1802 microprocessor. Thirty-nine stuck faults were not detected out of a total of 874 injected into the combinatorial and sequential parts of the microprocessor. Since undetected faults can create catastrophic errors in equipment designed for high reliability applications, it is recommended that the MIL-M-38510/470 NASA be enhanced with additional test vectors so as to achieve 100% stuck fault detection efficiency.
