Detecting Urgency Status of Crisis Tweets: A Transfer Learning Approach for Low Resource Languages (2020)

We release an urgency dataset that consists of English tweets relating to natural crises. The set is annotated along with annotations of their corresponding urgency status. Additionally, we release evaluation datasets for two low-resource languages, i.e. Sinhala and Odia, and demonstrate an effective zero-shot transfer from English to these two languages by training cross-lingual classifiers. We adopt cross-lingual embeddings constructed using different methods to extract features of the tweets, including a few state-of-the-art contextual embeddings such as BERT, RoBERTa and XLM-R. We train a variety of classifier architectures, supervised and semi supervised, on the extracted features. We also further experiment with ensembling the various classifiers. With very limited amounts of labeled data in English and zero data in the low resource languages, we show a successful framework of training monolingual and cross-lingual classifiers using deep learning methods which are known to be data hungry. Specifically, we show that the recent deep contextual embeddings are also helpful when dealing with very small-scale datasets. Classifiers that incorporate RoBERTa yield the best performance for the English urgency detection task, with 25% F1 score absolute improvement over the baselines. For the zero-shot transfer to low resource languages, classifiers that use LASER features perform the best for Sinhala transfer while XLM-R features benefit the Odia transfer the most.
The Hilbert Generator, a Filter-Free Upconverter for 6G Communications (2020)

This paper presents a new type of architecture for the conversion of wide frequency bands to high frequencies beyond 100GHz in order to overcome technological obstacles for 6G. It is proposed to consider the Hilbert transform as a mathematical tool for the design of a system natively rejecting the image frequencies in order to save on blocks like filters and mixers. It is shown that an appropriate conversion makes it possible to reject images of the order of several tens of dB, in simulation with CW, modulated (64-QAM) and multi-carrier signals. An experiment is carried out, at low frequencies, to demonstrate the concept.
A Tutorial Introduction to Research on Analog and MixedSignal Circuit Testing (2009)

<P>Traditionally, work on analog testing has focused on diagnosing faults in board designs. Recently, with increasing levels of integration, not just diagnosing faults, but distinguishing between faulty and good circuits has become a problem. Analog blocks embedded in digital systems may not easily be separately testable. Consequently, many papers have been recently written proposing techniques to reduce the burden of testing analog and mixed-signal circuits. This survey attempts to outline some of this recent work, ranging from tools for simulation-based test set development and optimization to built-in self-test (BIST) circuitry.</P>
Tolerance in Staphylococcus aureus: Evidence for Bacteriophage Role (1980)

The conversion of nontolerant Staphylococcus aureus to a tolerant organism is reported. It had been shown previously that a nontolerant strain produces tolerant progeny when it is incubated in media that contain a bacteria-free filtrate derived from cultures of each of the three tolerant stains of S. aureus. The tolerant progeny retain the characteristic tolerance upon serial subculture, and cell-free filtrates prepared from such subcultures are capable of converting nontolerant organisms to tolerant bacteria. A study of filtrates made from one of the tolerant strains revealed that all of the converting activity was sedimented by ultracentrifugation. DNase I and RNase A did not reduce the activity of the sediment, but Proteinase K completely diminished it. Equilibrium centrifugation of filtrates in cesium chloride showed that the conversion activity was maximal in the fraction with a density of approximately 1.445 +/- 0.015 g/ml. When a portion of this fraction was examined with the electron microscope, hexagonal bacteriophages (20 nm in diameter) were seen at this density. This observation seems to be evidence that a bacteriophage is involved in conversion of S. aureus from a nontolerant to a tolerant organism.
Abstract B37: Analysis of non-small cell lung cancer (NSCLC) circulating biomarkers for monitoring early response to radiation therapy (2020)

Abstract Approximately 20% of non-small cell lung cancer (NSCLC) patients will be diagnosed with stage 3 cancer, with a predicted survival rate between 20-30%. Stage 3 NSCLC patients commonly undergo chemoradiation treatment, with imaging scans being the standard of care for determining tumor control or progression both during and after radiation treatment. Imaging technologies can only show progression after it has occurred, making treatment challenging. We suggest that the molecular characterization of biomarkers found in the bloodstream can identify or predict radiation treatment efficacy before progression becomes visible on a scan. In this study, patients undergo a response-driven adaptive radiation therapy (RDART) protocol: four weeks of chemoradiation followed by a set of imaging scans before an additional 2 weeks of adapted, personalized radiation with chemotherapy. In this work, we provide combined analysis of both circulating tumor cells (CTCs), a rare cell found in a patient’s peripheral blood, and exosomes, nanovesicles excreted from cells, for use in assessing radiation efficacy. Our initial cohort is 30 patients, and we aimed to collect six timepoints: one pretreatment, two during radiation treatment, and three after radiation treatment. In this study, we look at the changes in several characteristics: CTC counts, PD-L1 expression on CTCs, as well as gene expression changes of both CTCs and exosomes using Affymetrix microarrays. CTCs were isolated using a graphene oxide (GO)-based microfluidic device and were found to be present in all pretreatment samples and most following samples. Initial transcriptome profiling of 5 patients using microarrays highlighted clustered gene expression differences for both CTCs and exosomes when comparing pretreatment samples with those collected during radiation.

FAST MOTION IMAGING USING REDUCED FIELD OF VIEW PARTIAL FOURIER MRI (2007)

Fast MR imaging techniques often exploit the redundancy present in an underlying MR image time series to compensate for k-space undersampling. When imaging motion using techniques like HARP, DENSE, and phase contrast (PC), it is the phase in static regions that is constant and therefore redundant. In this paper, we present a technique that first estimates the phase in the static portion of an undersampled MR image time series and then uses a partial Fourier reconstruction technique to combine phase in the static portion and undersampled data to reconstruct the full image time series. The technique is illustrated using a computational phantom undergoing simulated cardiac motion and imaged using the HARP protocol. Results demonstrate a gradual degradation of accuracy with loss of data due to undersampling, indicating that a 25% speedup in imaging time is possible for an image time series in which 50% of the pixels correspond to the object that do not move over time.
Efficacy and Safety of Vilobelimab (IFX-1), a Novel Monoclonal Anti-C5a Antibody, in Patients With Early Severe Sepsis or Septic Shock—A Randomized, Placebo-Controlled, Double-Blind, Multicenter, Phase IIa Trial (SCIENS Study) (2021)

Administration of vilobelimab in patients with severe sepsis and septic shock selectively neutralizes C5a in a dose-dependent manner without blocking formation of the membrane attack complex and without resulting in detected safety issues. The data warrant further investigation of C5a inhibition in sepsis.
HyperDense-Net: A Hyper-Densely Connected CNN for Multi-Modal Image Segmentation (2018)

Recently, dense connections have attracted substantial attention in computer vision because they facilitate gradient flow and implicit deep supervision during training. Particularly, DenseNet that connects each layer to every other layer in a feed-forward fashion and has shown impressive performances in natural image classification tasks. We propose HyperDenseNet, a 3-D fully convolutional neural network that extends the definition of dense connectivity to multi-modal segmentation problems. Each imaging modality has a path, and dense connections occur not only between the pairs of layers within the same path but also between those across different paths. This contrasts with the existing multi-modal CNN approaches, in which modeling several modalities relies entirely on a single joint layer (or level of abstraction) for fusion, typically either at the input or at the output of the network. Therefore, the proposed network has total freedom to learn more complex combinations between the modalities, within and in-between all the levels of abstraction, which increases significantly the learning representation. We report extensive evaluations over two different and highly competitive multi-modal brain tissue segmentation challenges, iSEG 2017 and MRBrainS 2013, with the former focusing on six month infant data and the latter on adult images. HyperDenseNet yielded significant improvements over many state-of-the-art segmentation networks, ranking at the top on both benchmarks. We further provide a comprehensive experimental analysis of features re-use, which confirms the importance of hyper-dense connections in multi-modal representation learning. Our code is publicly available.
Hand-eye calibration of a robot - UltraSound probe system without any 3D localizers (2015)

3D UltraSound (US) probes are used in clinical applications for their ease of use and ability to obtain intra-operative volumes. In surgical navigation applications a calibration step is needed to localize the probe in a general coordinate system. This paper presents a new hand-eye calibration method using directly the kinematic model of a robot and US volume registration data that does not require any 3D localizers. First results show a targeting error of 2.34 mm on an experimental setup using manual segmentation of five beads in ten US volumes.
Endotoxin removal therapy with Polymyxin B immobilized fiber column as a COVID-19-bedside strategy protocol for endotoxic shock (2022)

Endotoxin -induced sepsis is a leading cause of ICU mortality. From 1994 to the present, PMX-HP has been available as an adjuvant therapy for endotoxin removal and immunomodulation. The efficacy and usefulness of this therapy have been demonstrated for more than a quarter of a century and are partially supported by clinical studies. However, it appears that selected subgroups of patients with endotoxic shock and with appropriate timing could benefit. Endotoxemia may be involved in the pathophysiology of COVID-19, based on enterocyte dysfunction and malabsorptive syndrome. Due to the characteristics of the microbiota, Gram-negative bacteria or their fragments (i.e., endotoxin) may translocate into the systemic circulation leading to inflammatory activation, immune dysfunction, and sepsis. In addition, patients with severe forms of COVID-19 are at risk of superimposed infections. Endotoxemia can arise due to the translocation of Gram-negative bacteria or their fragments from the gut barrier. According to the most updated evidence available from large randomized trials, septic shock patients with MODS > 9 and EA levels ranging from 0.6 to 0.9 are those who may benefit the most from PMX-HP treatment in terms of improvement of survival. As shown in a previous publication, we believe that similarly to the source control, microbiological cultures, and antibiotics administration, EA evaluation at regular intervals, and the targeted use of PMX-HP could be lifesaving and adequate within the golden hour for the diagnosis and treatment of endotoxic shock. In our center, we applied a diagnostic-clinical flowchart also for endotoxic shock related to COVID-19.

A Review of the Genus Orchestomerus Dietz (Coleoptera: Curculionidae: Ceutorhynchinae: Cnemogonini) of the USA (2015)

The genus Orchestomerus Dietz contains four species in the USA: O. wickhami Dietz, O. eisemani Yoshitake and Anderson, new species, O. marionis (Fall), resurrected species and new combination, and O. whiteheadi Colonnelli. Orchestomerus ulkei Dietz, previously considered the valid name for O. marionis, is a new junior subjective synonym of Auleutes epilobii (Paykull), which in turn makes Platymeristes Dietz a new junior synonym of Auleutes Dietz. Diagnostic features of Orchestomerus, illustrations of the four species, and a key to separate them are presented. Orchestomerus species are associated with Vitaceae: Cissus trifoliata (l.) L. for O. wickhami in Texas; Parthenocissus quinquefolia (L.) Planch. for O. eisemani in Indiana, Maryland, Massachusetts, and North Carolina, Vitis sp. for O. marionis in Georgia and Missouri, and Vitis arizonica Engelm. for O. whiteheadi in Arizona.

Effect of material geometry on cartilagenous tissue formationin vitro (2001)

The effect of material geometry, as defined by average pore size, on chondrocyte phenotype and cartilagenous tissue formation in vitro was examined. Bovine articular chondrocytes were plated on porous titanium alloy (Ti6Al4V) discs of different average pore sizes (13, 43, and 68 microm) and grown in culture for 4 weeks. Chondrocyte phenotype was maintained as indicated by the synthesis of large proteoglycans (Kav +/- SD: 13 microm = 0.28 +/- 0.01; 43 microm = 0.29 +/- 0.01; 68 microm = 0.27 +/- 0.02) and type II collagen. Light microscopical examination of histological sections of the composites showed that cartilagenous tissue had formed on all discs. The cartilagenous tissue on the discs of the smallest average pore size (13 microm) was significantly thicker than the tissue on the discs of larger average pore sizes and also had greater amounts of proteoglycan [mean glycosaminoglycan content +/- SD microg/disc): 13 microm = 246.9 +/- 7.8; 43 microm = 190.4 +/- 10.2; 68 microm = 156.6 +/- 25.8, p = 0.002] and DNA [mean DNA content +/- SD microg/disc): 13 microm = 12.5 +/- 0.6; 43 microm = 8.3 +/- 0.2; 68 microm = 9.3 +/- 0.9, p = 0.0008]. However, the amount of proteoglycan accumulated per cell was similar in the tissues generated on the discs of different average pore sizes. In contrast, the amount of collagen in the cartilagenous tissues showed no significant differences between the different pore sizes, but the amount of collagen accumulated per cell was less in the tissue formed on the smallest pore size disc (13 microm) as compared with the tissue formed on the discs of the larger pore sizes [mean hydroxyproline content/DNA (microg/microg) +/- SD: 13 microm = 1.56 +/- 0.2; 43 microm = 2.19 +/- 0.2; 68 microm = 2.3 +/- 0.3]. These results suggest that material geometry, as defined by pore size, can affect the amount and composition of the cartilagenous tissue that forms.
Rapid, Low-Technology MIC Determination with Clinical <i>Mycobacterium tuberculosis</i> Isolates by Using the Microplate Alamar Blue Assay (1998)

A colorimetric, microplate-based Alamar Blue assay (MABA) method was used to determine the MICs of isoniazid (INH), rifampin, streptomycin (SM), and ethambutol (EMB) for 34 Peruvian Mycobacterium tuberculosis isolates (including both pansensitive and multidrug-resistant strains) and the H37Rv strain by using bacterial suspensions prepared directly from solid media. Results for all isolates were available within 8 days. Discordant results were observed on initial tests for 3 of 16 INH-susceptible isolates, 5 of 31 EMB-susceptible isolates, and 2 of 4 SM-resistant isolates (by the BACTEC 460 system). The overall agreements between the MICs obtained by MABA and the results obtained with the BACTEC 460 system were 87.9% for initial results and 93.6% after retesting 12 of 17 samples with discrepant results. Interpretation of MABA endpoints improved with technical experience. The MABA is a simple, rapid, low-cost, appropriate technology which does not require expensive instrumentation and which makes use of a nontoxic, temperature-stable reagent.
Fractionation of Lactoperoxidase and Lactoferrin from Bovine Whey Using a Cation Exchange Membrane (1997)

ABSTRACT A microporous membrane containing immobilized sulfonic acid moieties was used for the rapid fractionation of the cations lactoperoxidase (LP) and lactoferrin (LF) from whey. The breakthrough curves of LP and LF, the LP activity and LF concentration in the elution peaks for different whey loading volumes, and the stability of membrane performance over repeated cycles of loading and elution were measured. Recovery was unaffected by an 8‐fold scale‐up exercise and repeated cycling, and was 73–6% for LP and 50–5% for LF. The membrane system was more rapid, smaller in size, and used a higher flow rate than traditional bead‐based systems.

&lt;title&gt;Time-resolved x-ray diffraction with subpicosecond x-ray pulses&lt;/title&gt; (2001)

The emission from plasmas created with fs-lasers provides sub-picosecond x-ray pulses in the keV-range. Intense emission of K(alpha) lines as well as quasi continuum x-rays can be used for time-resolved diffraction and spectroscopy, i.e. to study lattice or atomic dynamics with sub-picosecond resolution by using a laser pump x-ray probe technique. The x-ray yield and x-ray pulse duration of the laser plasma source depend on the laser parameters and the target design, such as intensity, laser wavelength, pulse duration and prepulse level. To accumulate as many photons as possible of the isotropic source an efficient large aperture optic has to be used to select an x-ray line or a wavelength range and focus the radiation onto the sample. It is shown that the use of toroidally bent crystals provides the possibility to refocus 10<SUP>-4</SUP> of the photons emitted in the whole solid angel to spot size of around 80 micrometers with a temporal broadening below 100 fs. Combinations of bent focusing crystals with a flat sample crystal for fast x-ray diffraction application are discussed. Experiments showing the temporal response of laser heated crystals are presented and compared with theoretical simulations based on Takagi-Taupin theory.
Management of genetic diversity in small farm animal populations (2011)

Many local breeds of farm animals have small populations and, consequently, are highly endangered. The correct genetic management of such populations is crucial for their survival. Managing an animal population involves two steps: first, the individuals who will be permitted to leave descendants are to be chosen and the number offspring they will be permitted to produce has to be determined; second, the mating scheme has to be identified. Strategies dealing with the first step are directed towards the maximisation of effective population size and, therefore, act jointly on the reduction in the loss of genetic variation and in the increase of inbreeding. In this paper, the most relevant methods are summarised, including the so-called 'Optimum Contribution' methodology (contributions are proportional to the coancestry of each individual with the rest), which has been shown to be the best. Typically, this method is applied to pedigree information, but molecular marker data can be used to complete or replace the genealogy. When the population is subjected to explicit selection on any trait, the above methodology can be used by balancing the response to selection and the increase in coancestry/inbreeding. Different mating strategies also exist. Some of the mating schemes try to reduce the level of inbreeding in the short term by preventing mating between relatives. Others involve regular (circular) schemes that imply higher levels of inbreeding within populations in the short term, but demonstrate better performance in the long term. In addition, other tools such as cryopreservation and reproductive techniques aid in the management of small populations. In the future, genomic marker panels may replace the pedigree information in measuring the coancestry. The paper also includes the results of several experiments and field studies on the effectiveness and on the consequences of the use of the different strategies.
