Reversible Cerebral Arteriopathy Associated with the Administration of Ergot Derivatives (1984)

Three cases of intracranial arteriopathy associated with the administration of ergot derivatives are reported. In the first case, excessive doses of dihydroergotamine and of ergotamine tartrate seemed to be the cause, but simultaneous treatment with an antibiotic and the existence of a cytomegalovirus infection could have favoured the arteriopathic process. The second patient also received excessive doses of these two drugs, but in addition she was taking oestrogen and progesteron containing contraceptives. In the third case, an intravenous injection of methylergometrine in a dose of 0.2 mg seemed to have initiated the arteriopathy. Arteriograms were comparable in all three cases, with segmental stenosis of several cerebral arteries, whereas internal carotid and vertebral arteries remained normal. In the first case a control cerebral arteriography was normal one month later. These findings suggest that widespread cerebral arteriopathy can appear in subjects who chronically abuse ergotamine tartrate.

The paper provides a clear 3GPP state of the art, including when the 3GPP work on D2D and public safety communications started. Finally, it presents important conclusions with respect to further 3GPP work on this topic.
CD4 modulation and inhibition of HIV-1 infectivity induced by monosialoganglioside GM1 in vitro (1989)

The addition of monosialoganglioside GM1 to serum-free culture medium efficiently and specifically inhibited CD4 antigen expression on normal T lymphocytes from peripheral blood or thymus as well as on cells from H9 and Molt-3 lines; other molecules such as CD3, CD2 and CD8 were not affected. Subsequent addition of fetal calf serum or bovine and human serum albumin blocked GM1 action on CD4 expression, most likely through the formation of ganglioside-albumin complexes. Removal of GM1 from the medium was followed by the prompt reappearance of CD4 on the cell surface. GM1 treatment of H9 and Molt-3 cells greatly reduced HIV-1 infectivity, which was evaluated by reverse transcriptase activity levels in culture supernatants and p24 detection on target cells. GM1 also inhibited syncytial formation in Molt-3 cells even when treatment was initiated 24h after infection. The GM1 effect on HIV-1 infectivity, however, was not long-lasting since removal of the compound was followed by a rapid increase in viral replication, probably due to CD4 re-expression and HIV-1 propagation from a few initially infected cells.
High-Accuracy Settling Time Measurements (1983)

Methods are described for measuring the settling times and other dynamic characteristics of voltage and current output D/A converters (DAC's), operational amplifiers, and precision voltage step generators. Circuits are described for measuring voltage-output device settling times as short as 1μs to within a settling error of ±2 ppm, and current-output device settling times as short as 40 ns to within a settling error of ±0.012 percent.
TRANSIENT DROPLET SIZE SPECTRA FROM TRIGGER SPRAYERS DISPENSING AQUEOUS SOLUTIONS (2005)

Disposable trigger sprayers are commonly used to dispense ready-to-use pesticides formulated for consumer andhomeowner application. Generation of aerosol-sized, mobile droplets from the sprayers can result in potential inhalationexposure for the user and movement of spray to non-target areas. This study measured the droplet size spectra produced byconventional and foamer-type trigger sprayers during 75 to 200 ms bursts of 0.9 mL spray volume. Water was used as thecarrier, and test formulations were prepared by adding combinations of a surfactant (Silwet L-77) and a long-chain polymer(polyethylene oxide). The Dv0.1, Dv0.5, and Dv0.9 statistics of the droplet size spectra were found to vary over the duration ofspray emission; significantly larger droplet size spectra were produced during 15 to 50 ms initiation and conclusion periodsof the pulse. Typical Dv0.5 values of the spray varied from 100 to 600 .m for spray pulses from a conventional trigger sprayerdispensing a water + surfactant solution and a foamer-type trigger sprayer dispensing a water + polymer solution,respectively. Addition of the polymer significantly increased the droplet size spectra, particularly with the conventionalnozzle. A second-order model was found to describe the temporal relationship between the droplet size spectral statistics andthe time since initiation of the spray pulse.
Automatic Detection and Language Identification of Multilingual Documents (2014)

Language identification is the task of automatically detecting the language(s) present in a document based on the content of the document. In this work, we address the problem of detecting documents that contain text from more than one language ( multilingual documents). We introduce a method that is able to detect that a document is multilingual, identify the languages present, and estimate their relative proportions. We demonstrate the effectiveness of our method over synthetic data, as well as real-world multilingual documents collected from the web.
Streaming media caching algorithms for transcoding proxies (2003)

Streaming media is expected to become one of the most popular types of Web content in the future. Due to increasing variety of client devices and the range of access speeds to the Internet, multimedia contents may be required to be transcoded to match the client's capability. With transcoding, both the network and the proxy CPU are potential bottlenecks for streaming media delivery. This paper discusses and compares various caching algorithms designed for transcoding proxies. In particular we propose a new adaptive algorithm that dynamically selects an appropriate metric for adjusting the management policy. Experimental results show that the proposed algorithm significantly outperforms those that cache only untranscoded or only transcoded objects. Moreover motivated by the characteristics of many video compression algorithms, we investigate partitioning a video object into sections based on frame type and handling them individually for proxy caching. It is found that partitioning improves performance when CPU power rather than network bandwidth is the limiting resource, particularly when the reference pattern is not highly skewed.
Effects of cation contaminants in conductive TiO2 ceramics (1982)

Ten cation contaminants, namely Al, Ga, Co, Fe, Mg, Zn, Zr, Ca, Sr, and Ba were investigated for their effects on the electrical properties, microstructures, and discoloration of conductive TiO2 ceramics. It was found that Al, Ga, Co, Fe, and Mg cause discoloration and increase the electrical resistivity by a factor of 104 to 106 in Nb-doped TiO2 ceramics. The other dopants do not introduce such changes in TiO2. The electrical properties, microstructures, and discoloration were measured in specimens of AlxNb0.007Ti0.993−xO2 with 0≤x≤0.01. When the Al content exceeds a critical value, ranging from 0.48% at 1400 °C to 0.25% at 1200 °C, the electrical resistivities and grain size increase rapidly, and the specimen is discolored from the original black to an ivory white color. Color boundary migration induced by Al diffusion in Nb-doped TiO2 was quantitatively measured. From the kinetics of the boundary migration, the Al diffusivity (D) was calculated to be D=2.67 exp(−53.3 kcal/mole/RT) cm2/s in the temperature range of 1200 to 1400 °C. The rapid diffusion of the small cations, namely Al, Ga, Co, Fe, and Mg, results from an interstitial diffusion mechanism. However, other cations, having a radius larger than the interstitial channel (∼0.77 Å radius), cannot diffuse by this mechanism. Defect reactions are proposed to explain the increase in the electrical resistivity and microstructural changes due to Al diffusion. These defect reactions also show that the problem of acceptor contamination cannot be avoided by adding an excess quantity of donor dopant if the solubility of the donor is much less than that of the acceptor contaminant.
The value of investigation for genetic counselling in tuberous sclerosis. (1990)

Forty sets of parents and 24 sibs of patients with tuberous sclerosis were investigated by an extensive protocol, including clinical examination of skin, hair, and oral cavity, direct and indirect ophthalmoscopy, cranial CT scan, renal ultrasound, and a radiological skeletal survey. None of the clinical examinations provided evidence that any of the subjects was affected. Similarly, the cranial CT scan, renal ultrasound, and skeletal survey failed to identify any occult gene carriers. All of these investigations showed abnormalities in some parents but none was diagnostic. This study shows the difficulties in interpretation that these investigations may produce with consequent problems for genetic counselling. The study does not support the routine use of these tests. There are published reports where the diagnosis of tuberous sclerosis has been made in adults exclusively on a CT scan and an argument can be made for including this investigation. There is no indication for performing renal ultrasound nor skeletal x rays in parents who have normal clinical examinations.
Automated ingest of digital records from electronic records management systems (2010)

The amount of vital electronic records created at the agencies grows constantly, as does the need for efficient methods and tools which help to transfer records into trusted long-term repositories. This paper describes a tool called the Universal Archiving Module (UAM) which simplifies and automates the process of preparing records and their metadata for transfers into long-term repositories. Developed by the National Archives of Estonia the tool speeds up the transfer process by reusing already available records management metadata and by automating technical validation and normalisation processes.
Digital image translational and rotational motion stabilization using optical flow technique (2002)

This paper proposes a new digital image stabilization (DIS) system based on optical flow technique. Unlike previous DIS systems developed mainly for removing the translational motion disturbance, the proposed system removes not only the translational but also the rotational motion disturbances. A computational scheme that facilitates the local motion vector field to estimate the global disturbing translational and rotational motions is developed. First, the optical flow technique is used to estimate the local motion vector field of the image, yielding the velocity of each pixel in the current image frame. Then, the global translational and rotational motion parameters are determined in terms of the least squares estimation. Finally, these motion vectors are used to generate the counterbalance signals for removing the disturbance motion. Owing to the additional ability of the rotational motion removal, the new DIS system suppresses the undesirable translational and rotational disturbances effectively and thus enhances the DIS performance significantly.
Targeting Prolactin Receptor (PRLR) Signaling in PRLR-Positive Breast and Prostate Cancer (2016)

In this issue of The Oncologist, Agarwal et al. report negative results from a phase I trial of LFA102. Although “negative” in terms of antitumor activity, the study provides useful pharmacokinetic and pharmacodynamic information. Future trials evaluating PRLR blockers alone and in combination with other agents may still be warranted in patients with breast and prostate cancer.
A wide-band microwave photonic phase and frequency shifter (1997)

Advanced radar deception systems require wide-band devices which perform microwave processing of frequency and phase information. A wide-band microwave photonic phase shifter was constructed which is capable of imposing greater than 2/spl pi/ phase shift to microwave signals in the 2-18-GHz frequency range. The maximum standard deviation from the phase setting was 10/spl deg/ (7/spl deg/ typical). The phase shifter was then incorporated into a frequency translation architecture. The carrier suppression obtained was 50 dB with a spurious harmonic suppression of 23 dB.
Automated energy model creation for conceptual design (2011)

Architects today rarely use whole building energy analysis to inform their early design process. During this stage of design, the team is responsible for macro-level decisions (such as basic form and orientation) that can have the most significant effects on energy use. So why are so few architects using energy analysis tools at this stage? In many cases, this is because the tools available to perform energy analysis are too complex and time-consuming to learn and use during the fast-paced conceptual design phase because of the time needed to model and analyze the design. Often energy analysis tools are separate, standalone applications that require a separate thermal model to be authored. This adds more time and complexity and limits the number of professionals experienced with these tools. Understanding the results and using them in presentations is also quite difficult in current tools.This paper describes a system that can alleviate these problems by automatically generating an energy model from an architect's basic massing model. Our approach allows an architect to focus on modeling the building form, rather than the thermal zones that are the focal point for most energy modeling software on the market today. The architect's massing model can then be modified and the energy model stays in sync, allowing comparative analyses to be made quickly and easily.
Intraepidermal Accumulation of Polymorphonuclear Leukocytes in Chronic Stable Plaque Psoriasis (1987)

The intraepidermal penetration of polymorphonuclear leukocytes is an early event in the pathogenesis of psoriasis. In the present study we quantified these cells in biopsies from lesional epidermis of chronic stable plaque psoriasis. In this phase intraepidermal penetration of polymorphonuclear leukocytes was shown in 41% of the lesions. Micropustules of Kogoj were seen in 10% of the lesions. Pronounced parakeratosis was associated with the presence of polymorphonuclear leukocytes. Microabscesses of Munro were located exclusively within areas of parakeratosis. The absence of polymorphonuclear leukocytes in the majority of skin biopsies from chronic stable plaque psoriasis is compatible with the cyclic pattern of the exocytosis of these cells.
A novel low resistance gate fill for extreme gate length scaling at 20nm and beyond for gate-last high-k/metal gate CMOS technology (2012)

Replacement metal gate (RMG) process requires gate fill with low resistance materials on top of work function tuning metals. Conventional titanium (Ti)-aluminum (Al) based RMG metal fill scheme for low resistance gate formation becomes challenging with further gate length scaling for 20nm node and beyond. In this work, we have demonstrated competitive low resistance gate formation at smaller than 25nm L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">gate</sub> using a novel cobalt (Co)-aluminum based metal fill scheme for extreme gate length scaling. Challenges in CMP for the implementation as well as assessment on resistance and device characteristics of this new low resistance fill scheme are also discussed.
<i>In situ</i> bioventing of a diesel fuel spill (1993)

Abstract An estimated 50 000 1 of diesel fuel contaminated soil over a depth of 1.5 to 3.5 m (approximately 1.5% by weight in the soil) following fuel recovery operations at the site of a diesel spill. Laboratory treatability identified oxygen supply treatment as having significant potential to enhance bioremediation of the soil in situ. A bioventing system was designed and tested on a quarter of the site. Venting alone over a period of six months reduced total hydrocarbon concentrations by 10 to 30% to a depth of 3 m. Venting with nutrient addition resulted in a further reduction of 30% over a subsequent 6 month period to the full depth of 3.5 m.
Studies on the pharmacology of the novel histamine H3 receptor agonist Sch 50971. (1998)

Experiments were performed to characterize the pharmacology of Sch 50971 ((+)-trans-4-(4(R)-methyl-3(R)-pyrolidinyl)-1H-imidazole dihydrochloride, CAS 167610-28-8), a novel histamine H3 receptor agonist. The activity of Sch 50971 was compared with that of (R)-alpha-methylhistamine (CAS 75614-87-8), a potent and moderately selective agonist of histamine H3 receptors, in a series of in vitro and in vivo assays. Sch 50971 is a high affinity, selective H3 receptor agonist in vitro and in vivo. Sch 50971 inhibits [3H]-N-alpha-methylhistamine (CAS 673-50-7) binding to the histamine H3 receptor in human brain (Ki = 5.0 nmol/l) and guinea pig brain (Ki = 2.5 nmol/l). Sch 50971 also inhibits electric field stimulated guinea pig ileum contractions (pD2 = 7.47) and decreases [3H]-norepinephrine (CAS 51-41-2) release (pD2 = 7.48) from guinea pig pulmonary artery by activation of presynaptic inhibitory H3 receptors. The in vitro effects of Sch 50971 are antagonized by low concentrations of a selective H3 antagonist, thioperamide (CAS 106243-16-7). Sch 50971 has low affinity (IC50's > 10 mumol/l) for histamine H1, dopamine D1 and D2, serotonin 5-HT2 and muscarinic cholinergic receptors. It also does not exhibit histamine H2-antagonist activity. In guinea pigs and cats, Sch 50971 exhibits in vivo H3 agonist activity. Sch 50971 inhibits sympathetic hypertension evoked by stimulation of the medulla oblongata in anesthetized guinea pigs (ED30 = 0.3 mg/kg i.v., ED30 = 1.0 mg/kg i.d.). Sch 50971 also inhibits the effects of sympathetic nerve stimulation on nasal resistance in cats. In these assays, Sch 50971 exhibits an efficacy and potency comparable to H3-agonist (R)-alpha-methylhistamine. However, under in vivo conditions, Sch 50971 does not exhibit histamine H1-mediated responses that are seen with (R)-alpha-methylhistamine at doses close to those that produce H3 effects. Therefore, Sch 50971 is a novel, potent and selective agonist of histamine H3 receptors with an improved in vitro and in vivo receptor profile selectivity compared with (R)-alpha-methylhistamine.

Dynamic Bit-Width Adaptation in DCT: An Approach to Trade Off Image Quality and Computation Energy (2009)

This paper presents a dynamic bit-width adaptation scheme for applications using discrete cosine transform (DCT). The technique can efficiently trade off image quality and computation energy. Based on sensitivity differences of 64 DCT coefficients, separate operand bit-widths are used for different frequency components to reduce computation energy. To select the appropriate operand bit-widths that achieve significant reduction of power consumption with minimum image quality degradation, we also propose a bit-width selection algorithm. The proposed variable bit precision DCT algorithm can be efficiently implemented using carry save adder trees. The reconfigurable DCT architecture can achieve power savings ranging from 36% to 75% compared to normal operation at the expense of minor image quality degradation.
Language Matters In Twitter: A Large Scale Study (2021)

Despite the widespread adoption of Twitter internationally, little research has investigated the differences among users of different languages. In prior research, the natural tendency has been to assume that the behaviors of English users generalize to other language users. We studied 62 million tweets collected over a four-week period and found that more than 100 languages were used. Only half of the tweets were in English (51%). Other popular languages including Japanese, Portuguese, Indonesian, and Spanish together accounted for 39% of the tweets. Examining users of the top 10 languages, we discovered cross-language differences in adoption of features such as URLs, hashtags, mentions, replies, and retweets. We discuss our work’s implications for research on large-scale social systems and design of cross-cultural communication tools.
Leveraging Weakly Annotated Data for Fashion Image Retrieval and Label Prediction (2017)

In this paper, we present a method to learn a visual representation adapted for e-commerce products. Based on weakly supervised learning, our model learns from noisy datasets crawled on e-commerce website catalogs and does not require any manual labeling. We show that our representation can be used for downward classification tasks over clothing categories with different levels of granularity. We also demonstrate that the learnt representation is suitable for image retrieval. We achieve nearly state-of-art results on the DeepFashion In-Shop Clothes Retrieval and Categories Attributes Prediction [12] tasks, without using the provided training set.
Asymmetric WDM all-optical packet switched routers (2002)

It is shown that asymmetric WDM all-optical routers architectures are the best candidates to reduce hardware volume and cost of all-optical networks. We show that due to the non-uniform network traffic behavior, routers require asymmetric wavelength conversion capabilities and also asymmetric buffering capacity to solve contention. This paper shows that due to the topology, packets may generate traffic bottlenecks produced by a tendency of the routing scheme to send packets with different destinations through preferred paths.
