Semi-Supervised Learning for Text Classification by Layer Partitioning (2020)

Most recent neural semi-supervised learning (SSL) algorithms rely on adding small perturbation to either the input vectors or their representations. These methods have been successful on computer vision tasks as the images form a continuous manifold, but are not appropriate for discrete input such as sentence. To adapt these methods to text input, we propose to decompose a neural network M into two components F and U so that M = U <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sub> F . The layers in F are then frozen and only the layers in U will be updated during most time of the training. In this way, F serves as a feature extractor that maps the input to high-level representation and adds systematical noise using dropout. We can then train U using any state-of-the-art SSL algorithms such as Π-model, temporal ensembling, mean teacher, etc. Furthermore, this gradually unfreezing schedule also prevents a pretrained model from catastrophic forgetting. The experimental results demonstrate that our approach provides improvements when compared to state of the art methods especially on short texts.
Crystal structure of Cd2V2O7 (1967)

Cadmium pyrovanadate crystallizes in the C2/m space group with lattice parameters a = 7.088(5) Å, b = 9.091(5) Å, c = 4.963(5) Å, β = 103°21(5)′, and z = 2. This crystal is an isostructure of the mineral thortveitite and thus the anion consists of a pair of centrosymmetrically related corner-sharing VO 4 tetrahedra while the cation resides within a distorted octahedron of oxygen atoms. The anion has a linear V—O—V group, but, as with the isostructural pyrophosphates, the central oxygen atom shows an anomalously high thermal activity. The V—O bond distances are 1.76 Å for the inner bond and 1.70 Å for the terminal bond. The bond angles about the anion and cation are similar to those found for the other analogues of thortveitite.
Effect of excluded volume on the force-extension of wormlike chains in slit confinement (2016)

We use pruned-enriched Rosenbluth method simulations to develop a quantitative phase diagram for the stretching of a real wormlike chain confined in a slit. Our simulations confirm the existence of a "confined Pincus" regime in slit confinement, analogous to the Pincus regime in free solution, where excluded volume effects are sensible. The lower bound for the confined Pincus regime in the force-molecular weight plane, as well as the scaling of the extension with force and slit size, agree with an existing scaling theory for this regime. The upper bound of the confined Pincus regime depends on the strength of the confinement. For strong confinement, the confined Pincus regime ends when the contour length in the Pincus blob is too short to have intrablob excluded volume. As a result, the chain statistics become ideal and the confined Pincus regime at low forces is connected directly to ideal chain stretching at large forces. In contrast, for weak confinement, the confined Pincus regime ends when the Pincus blobs no longer fit inside the slit, even though there is sufficient contour length to have excluded volume inside the Pincus blob. As a result, weak confinement leads to a free-solution Pincus regime intervening between the confined Pincus regime for weak forces and ideal chain stretching at strong forces. Our results highlight shortcomings in existing models for the stretching of wormlike chains in slits.
Reliability of the chin tuck neck flexion test for assessing endurance of short neck flexors in healthy individuals (2015)

Due to high reproducibility and discriminant validity, clinicians and researchers might want to consider using the CTNF test for the assessment of neck flexor endurance. However, they should seek alternative measurement tools when they want to avoid a large measurement error.
A signal processing view of strip-mapping synthetic aperture radar (1989)

The authors derive the fundamental strip-mapping SAR (synthetic aperture radar) imaging equations from first principles. They show that the resolution mechanism relies on the geometry of the imaging situation rather than on the Doppler effect. Both the airborne and spaceborne cases are considered. Range processing is discussed by presenting an analysis of pulse compression and formulating a mathematical model of he radar return signal. This formulation is used to obtain the airborne SAR model. The authors study the resolution mechanism and derive the signal processing relations needed to produce a high-resolution image. They introduce spotlight-mode SAR and briefly indicate how polar-format spotlight processing can be used in strip-mapping SAR. They discuss a number of current and future research directions in SAR imaging.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Use of a Molecular Genetic Platform Technology to Produce Human Wnt Proteins Reveals Distinct Local and Distal Signaling Abilities (2013)

Functional and mechanistic studies of Wnt signaling have been severely hindered by the inaccessibility of bioactive proteins. To overcome this long-standing barrier, we engineered and characterized a panel of Chinese hamster ovary (CHO) cell lines with inducible transgenes encoding tagged and un-tagged human WNT1, WNT3A, WNT5A, WNT7A, WNT11, WNT16 or the soluble Wnt antagonist Fzd8CRD, all integrated into an identical genomic locus. Using a quantitative real-time bioluminescence assay, we show that cells expressing WNT1, 3A and 7A stimulate Wnt/beta-catenin reporter activity, while the other WNT expressing cell lines interfere with this activation. Additionally, in contrast to WNT3A, WNT1 only exhibits activity when cell-associated, and thus only signals to neighboring cells. The reporter assay also revealed a rapid decline of Wnt activity at 37°C, indicating that Wnt activity is highly labile. These engineered cell lines will reduce the cost of making and purifying Wnt proteins and serve as a continuous, reliable and regulatable source of Wnts to research laboratories around the world.
Spirituality of Healing Touch Participants (2001)

Nurses and nonnurses involved in Healing Touch training were studied to determine if there was a difference in their perception of spirituality. There was no difference between the nurses and nonnurses on either the Spiritual Perspective Scale (F = .001, p = .970) or the Questionnaire on Spiritual and Religious Attitudes (F = .024, p = .878). There was a significant difference between the six levels of training in Healing Touch classes completed by the participants on the Spiritual Perspective Scale (F = 7.079, p = .000). The upper-level classes had higher scores than the lower levels. There was a difference on the Questionnaire on Spiritual and Religious Attitudes between levels of instruction completed (F = 3.326, p = .003). This suggests that there is a heightened sense of spiritual awareness in those in the higher levels of the program. It may be that involvement in an energy-based therapy is one way to develop spiritual awareness.
EPIDURAL ANESTHESIA RESTORES PANCREATIC MICROCIRCULATION AND DECREASES THE SEVERITY OF ACUTE PANCREATITIS. (2004)

Background and Aims: A decrease in pancreatic microcirculatory blood flow has been involved in the severity of acute pancreatitis. Because epidural anesthesia increases intestinal blood flow, we postulated that epidural anesthesia with bupivacaine might improve the pancreatic hypoperfusion induced by acute pancreatitis and concomitantly decrease the severity of the disease. Methods: In rats injected with taurocholic acid in the biliopancreatic duct, we measured the pancreatic microcirculatory blood flow (laser Doppler flowmetry) and the severity of the disease (amylasemia, metabolic acidosis, and acinar cell necrosis on histologic studies), in the presence or in the absence of epidural anesthesia. Results: Epidural anesthesia with bupivacaine, which had no effect in healthy rats, improved the pancreatic hypoperfusion induced by acute pancreatitis with a concomitant decrease in the severity of metabolic acidosis and a diminished tissue injury. Conclusions: Epidural anesthesia should therefore be considered as a new treatment to prevent the conversion of edematous to necrotizing acute pancreatitis.
Enhanced antifouling and flux performances of a composite membrane via incorporating TiO2 functionalized with hydrophilic groups of L‐cysteine for nanofiltration (2022)

Abstract A new TiO 2 nanoparticle modified via L‐cysteine is presented in this study. The L‐cysteine (cys) modified TiO 2 nanomaterials impact as membrane modifier was examined in terms of pure water flux, hydrophilicity, morphology, and resistance ability. The mixed matrix membranes morphology investigated by using scanning electron microscope (SEM), atomic force microscopy (AFM), water contact angle measurement, porosity and pore size and Fourier transform infrared spectroscopy analysis. Membrane hydrophilicity and permeation flux were notably improved by introducing TiO 2 ‐cys nanomaterials to the membrane matrix. The SEM image indicated the expanded finger‐like pores for the modified membranes comparing to the bare polyethersulfone (PES). The obtained AFM image exhibited lower surface roughness parameters for the modified membranes. In case of prepared membranes assessment, dye removal capability using the direct red‐16 and real liquorice wastewater were examined. The results confirmed that the modified membranes indicated high‐ranking dye rejection ability (more than 98% for direct red‐16 and 90% for real liquorice wastewater) comparing to the bare membrane (86 ± 2.58%). The antifouling tests were run based on milk powder (1000 mg/L) filtration and the best antifouling performance was obtained for 0.5 wt% of TiO 2 ‐cys membrane (flux recovery ratio = 90.57 ± 2.71%, R ir = 9.43 ± 0.28%). Also, the results showed high potential of TiO 2 ‐cys nanomaterials for membrane hydrophilicity enhancement.

Socio-demographic factors impact time to discharge following total knee arthroplasty (2018)

The cost of TKA is dependent upon LOS, which is affected by multiple factors. The clinical care team should acknowledge socio-demographic factors to optimize LOS.
Preparation and characterization of iminodiacetic acid-functionalized magnetic nanoparticles and its selective removal of bovine hemoglobin (2011)

In this study, a novel route for the preparation of magnetite (Fe(3)O(4)) nanoparticles (NPs) with immobilized metal affinity ligand iminodiacetic acid (IDA) charged with Cu(2+) was developed. First, magnetite nanoparticles were synthesized by a hydrothermal method. Charged with Cu(2+), the magnetic nanoparticles (MNPs) were applied to separate a model protein mixture of bovine hemoglobin (BHb) and bovine serum albumin (BSA). They could be separated completely and showed low non-specific adsorption. The morphology, structure and composition of the magnetite MNPs were characterized by transmission electron microscopy, power x-ray diffraction, x-ray photoelectron spectrometry and Fourier transform infrared spectroscopy. The resulting magnetite MNPs charged with Cu(2+) show not only a strong magnetic response to externally applied magnetic field, but are also highly specific to protein BHb. It is interesting that MNPs modified with metal ligands showed a property of magnetic colloid photonic crystals. Furthermore, they could efficiently remove the abundant protein bovine hemoglobin from bovine blood. They have potential application in removing abundant protein in proteomic analysis.
Functional consequences of an arginine180 to glutamine mutation in factor IX Hilo (1989)

Factor IX Hilo is a variant factor IX molecule that has no detectable coagulant activity. The defect in factor IX Hilo arises from a point mutation in the gene such that in the protein Arg180 is converted to a Gln. Activation of factor IX Hilo by factor Xla was monitored using the fluorescent active site probe p-aminobenzamidine. Normal factor IX showed complete activation in one hour as determined by measuring the increase in fluorescence when p-aminobenzamidine bound to activated factor IX. Factor IX Hilo showed no increase in fluorescence even after 24 hours, indicating that the active site was not exposed. Polyacrylamide gel electrophoresis showed that factor IX Hilo was cleaved to a light chain plus a larger peptide with a molecular weight equivalent to a heavy chain covalently linked to an activation peptide. Amino terminal amino acid sequencing of factor IX Hilo cleaved by factor Xla showed cleavage only at Arg145-Ala146, indicating that the Gln180-Val181 bond was not cleaved and that the active site was thus not exposed. The presence of factor IX Hilo in patient plasma was responsible for the patient having a very long ox brain prothrombin time characteristic of severe hemophilia Bm. Patient plasma had an ox brain prothrombin time of 100 seconds using a Thrombotest kit, significantly prolonged over the normal control value of 45 seconds. When factor IX Hilo was depleted from patient plasma using an immunoaffinity column, the ox brain prothrombin time decreased to 41 seconds. When factor IX Hilo was added back to depleted patient plasma, to normal plasma depleted of factor IX by the same affinity column, or to plasma from a CRM- hemophilia B patient, the ox brain prothrombin time was significantly prolonged. We conclude that the Arg180 to Gln mutation in factor IX Hilo results in a molecule that cannot be activated by factor Xla. Further, our data suggest that the mutation results in a molecule that interacts with components of the extrinsic pathway to give a prolonged ox brain prothrombin time.
High-content protein localization screening in vivo reveals novel regulators of multiciliated cell development and function (2017)

SUMMARY Multiciliated cells (MCCs) drive fluid flow in diverse tubular organs and are essential for development and homeostasis of the vertebrate central nervous system, airway, and reproductive tracts. These cells are characterized by dozens or hundreds of long, motile cilia that beat in a coordinated and polarized manner (Brooks and Wallingford, 2014). In recent years, genomic studies have not only elucidated the transcriptional hierarchy for MCC specification, but also identified myriad new proteins that govern MCC ciliogenesis, cilia beating, or cilia polarization (e.g. (Choksi et al., 2014b; Chung et al., 2014; Hoh et al., 2012; Ma et al., 2014; Treutlein et al., 2014)). Interestingly, this burst of genomic data has also highlighted the obvious importance of the “ignorome,” that large fraction of vertebrate genes that remain only poorly characterized (Pandey et al., 2014). Understanding the function of novel proteins with little prior history of study presents a special challenge, especially when faced with large numbers of such proteins. Here, we explored the MCC ignorome by defining the subcellular localization of 260 poorly defined proteins in vertebrate MCCs in vivo . Moreover, functional analyses that arose from results of the screen provide novel insights into the mechanisms by which the actin cytoskeleton simultaneously influences diverse aspects of MCC biology, including basal body docking, and ciliogenesis.
Simulating the structure and dynamics of human hair: Modelling, rendering and animation (1991)

Abstract We develop and present a new approach to modelling the characteristics of human hair, considering not only its structure, but also the control of its motion and a technique for rendering it in a realistic form. The approach includes a system for interactively defining the global positioning of the strands of hair on the head. Special attention is paid to the self shadowing of the hair. A mass/spring/hinge system is used to control a single strand's position and orientation. We demonstrate that this approach results in a believable rendition of the hair and its dynamics.
Synthesis of a Bulky and Electron-Rich Derivative of SEGPhos and Its Application in Ru-Catalyzed Enantioselective Hydrogenation of β-Ketoesters (2005)

The synthesis and resolution of a bulky and electron-rich derivative of SEGPhos and its application in Ru-catalyzed asymmetric hydrogenation reaction of beta-ketoesters are reported. Up to 99.5% ee was achieved. Under solvent-free reaction conditions, acetoacetates could be reduced with good enantioselectivity and high efficiency; a TON of 20 000 was obtained within 3.5 h. The results obtained were comparable to those when SEGPhos was applied.
The density matrix renormalization group in chemistry and molecular physics: Recent developments and new challenges (2020)

In the past two decades, the density matrix renormalization group (DMRG) has emerged as an innovative new method in quantum chemistry relying on a theoretical framework very different from that of traditional electronic structure approaches. The development of the quantum chemical DMRG has been remarkably fast: it has already become one of the reference approaches for large-scale multiconfigurational calculations. This perspective discusses the major features of DMRG, highlighting its strengths and weaknesses also in comparison with other novel approaches. The method is presented following its historical development, starting from its original formulation up to its most recent applications. Possible routes to recover dynamical correlation are discussed in detail. Emerging new fields of applications of DMRG are explored, such as its time-dependent formulation and the application to vibrational spectroscopy.
Using a claims database to investigate drug‐induced Stevens‐Johnson syndrome (1991)

In order to explore a priori hypotheses about drug-induced Stevens-Johnson Syndrome (SJS), a case-control study was initiated using data from COMPASS, a computerized data base consisting of Medicaid claims data. The records of 3.8 million patients in five U.S. states were searched to identify patients with an inpatient diagnosis of ICD-9-CM code 695.1 (erythema multiforme-EM). Out of the total of 367 cases that were identified, primary medical records for 249 were sought and 128 (51.4 per cent) of these were obtained. The remainder could not be obtained because: in 36 (29.8 per cent) the hospital refused to provide medical records; in 33 (27.3 per cent) there were transcription errors; in 20 (16.5 per cent) the state could not translate the identification number, primarily because the patients lost Medicaid eligibility too long before our request; in 27 (22.3 per cent) the hospital could not locate the patient's record; and in 5 (4.1 per cent) there were other reasons. Of those with a medical record, 121 (94.5 per cent) had a skin diagnosis and 109 (85.2 per cent) had a diagnosis compatible with ICD-9-CM code 695.1 specified on their discharge summary. However, in 35 (27.3 per cent) an expert reviewer felt that the discharge diagnosis was incorrect. In 50 (39 per cent) the computer diagnosis was incorrect. Only 19 (14.8 per cent) were judged by the expert reviewer to truly have Stevens-Johnson Syndrome, and an additional 37 (28.9 per cent) were judged to have erythema multiforme minor. Thus, the computerized diagnosis agreed very well with the diagnoses specified on the discharge summary. However, EM is frequently misdiagnosed, ICD-9-CM code 695.1 contains multiple other diagnoses which are not EM, and much of hospitalized EM is EM minor. Thus, studies of SJS cannot be performed except in patients whose medical records are available.
Aktive multistatische Nahbereichsabbildung mit ausgedünnten Gruppenantennen (2011)

Im Rahmen dieser Arbeit wurde ein Verfahren zur Nahbereichsabbildung im Frequenzbereich von f = 75-90 GHz analysiert und entwickelt. Das Verfahren bietet die Moglichkeit einer dreidimensionalen Rekonstruktion des untersuchten Messbereichs, bei einer nahezu echtzeitfahigen Datenaufnahme und einer moderaten Anzahl an Sende-/Empfangskanalen. Das Anwendungsgebiet ist die Untersuchung von Personen nach verborgenen Gegenstanden in sicherheitskritischen Bereichen, sowie die zerstorungsfreie Materialprufung (NDT) zur Detektion von Defekten oder Materialanomalien in dielektrischen Werkstoffen. Eine hoch aufgeloste Abbildung wird mit dem Verfahren der Apertursynthese erzielt. Dieses numerische Rekonstruktionsverfahren ermoglicht die optimale Fokussierung, eines raumlich ausgedehnten Messobjektes, fur jede Zielentfernung. Dies ist mit fokussierten Abbildungssystemen, welche lediglich am Fokusort eine hohe laterale Auflosung bieten, nicht moglich. Die entwickelten und implementierten Rekonstruktionsalgorithmen sind, bedingt durch die Anwendung, fur eine Nahbereichsabbildung optimiert. Die Moglichkeit der dreidimensionalen Objektrekonstruktion wird durch die Abtastung einer zweidimensionalen Apertur unter Verwendung eines breitbandigen Sende-/Empfangssignals ermoglicht. Hierfur wird eine lineare multistatische ausgedunnte Gruppenantenne verwendet, welche quer zur Anordnung der Antennenelemente mechanisch bewegt wird. Die Reduzierung der Gesamtanzahl an Sende- und Empfangsantennen wird nach dem Prinzip einer periodisch ausgedunnten Gruppenantenne erzielt. Da dieses Konzept lediglich im Fernfeld der Gruppenantenne gultig ist, wurde der Ansatz einer periodischen Ausdunnung, basierend auf theoretischen und simulativen Untersuchungen, fur Nahbereichsanwendungen erweitert. Das konzipierte mmW-System ermoglicht die Aufnahme eines 60 cm hohen Bildstreifens, wobei die Breite des rekonstruierten mmW-Bildes von der Lange des mechanischen Verfahrweges abhangt. Im Gegensatz zu einer vollelektronischen Abtastung der Abbildungsapertur, mit einer erheblichen Anzahl an Sende- und Empfangsantennen, ist bei diesem Konzept ein vergleichbar geringer technischer Aufwand notwendig. Bei dem untersuchten Abbildungsverfahren werden insgesamt 58 Sende- und Empfangsantennen benotigt. Im Fall eines zweidimensionalen vollelektronischen Arrays waren insgesamt 3364 Sende- und Empfangsantennen notwendig, um eine Abtastung der Apertur zu erreichen. Ein weiterer Vorteil des entwickelten Konzepts ist die flexible Wahl der Abbildungsapertur. Somit kann abhangig von dem zu untersuchenden Messobjekt eine planare oder zylindrische Abbildungsgeometrie realisiert werden. Dies gewahrleistet eine optimale Ausleuchtung des jeweiligen Messszenarios. Das entwickelte Abbildungskonzept sowie die implementierten Rekonstruktionsverfahren wurden an reprasentativen Messszenarien aus dem Sicherheitsbereich und dem Bereich der Materialprufung verifiziert.
MR head response from arrays of lithographically patterned perpendicular nickel columns (1997)

We report, for the first time, the MR head response from lithographically patterned perpendicular nickel columns. Electron-beam lithography is used to fabricate arrays of Ni columns, 400 nm tall and 150 nm in diameter spaced 2.1 /spl mu/m apart, embedded in SiO/sub 2/. The sample surface is planarized with a chemical mechanical polish. The technique of Scanning Magnetoresistance Microscopy (SMRM), in which a magnetoresistive (MR) head is raster-scanned in contact with a sample, is used to investigate the MR head response from the Ni columns. Single columns can be "read" with a 0-peak MR voltage of 60-70 /spl mu/V. Unexpectedly, we find that the magnetic field due to the bias current in the MR head is enough to switch the columns during scanning, which results in a "dibit-like" MR response, By scanning in the presence of a small (/spl sim/21 Oe) external magnetic bias field, the columns can be imaged in either their "up" or "down" magnetic states.
Tractament educatiu de les llengües a l'educació infantil (2013)

Conferència plenària i col.loqui al voltant del tractament educatiu del plurilingüisme a l'educació infantil. Producció: Facultat de Magisteri de la UV (www.uv.es/magisteri)
