Evaluation of a Spline-Based Parameterization Scheme for Phase-Only Antenna Pattern Synthesis (2022)

Phased Array Radars (PAR) are rapidly becoming the future for weather observations. The National Oceanic and Atmospheric Administration (NOAA) has identified PARs as a promising technology for polarimetric weather radar measurements. In particular, the ability of PARs to synthesize imaging beams with minimal sensitivity losses is becoming increasingly crucial for achieving the high-temporal resolution requirements. This paper introduces a novel phase-only beam pattern synthesis method using the Non-Uniform Rational B-Spline (NURBS) parameterization scheme. Based on a genetic algorithm optimization, it generates a phase distribution to excite the array and produce a desired beam shape. The proposed NURBS scheme is compared to previously used Bézier parameterization scheme. An S-band, 64-element uniform linear array (ULA) PAR was constructed to evaluate the performance of the NURBS scheme. Preliminary results show that the NURBS phase parameterization scheme can be used to synthesize phase weights for real-world PARs. Multiple metrics are used to evaluate the performance of the suggested parameterization scheme, such as half-power beamwidth and peak sidelobe levels. Results suggest that the NURBS scheme performs better than the Bézier scheme for synthesizing phase-only antenna patterns.
Effects of culture on PAMPS/PDMAAm double-network gel on chondrogenic differentiation of mouse C3H10T1/2 cells: in vitro experimental study (2014)

The present study showed that PAMPS/PDMAAm DN gel enhanced chondrogenesis of C3H10T1/2 cells, which are functionally similar to mesenchymal stem cells. This suggests that mesenchymal stem cells from the bone marrow contribute to spontaneous hyaline cartilage regeneration in vivo in large osteochondral defects after implantation of PAMPS/PDMAAm DN gels.

Incorporating Semantic Knowledge for Sentiment Analysis (2008)

We report work on using knowledge of sentiment-bearing words in statistical approaches to automatic sentiment analysis and opinion mining (SA &amp;amp; OM). Our main contribution lies in constructing document feature vectors that are sentiment-sensitive and use word knowledge. This is achieved by incorporating sentiment-bearing words as features in document vectors, extracted with the help of SentiWordNet which is essentially the wordnet with sentiment scores attached to the synsets. Support Vector Machines (SVM) have been used to classify documents into positive and negative polarity (i.e., sentiment) classes. Experiments
National Depressive and Manic-Depressive Association Consensus Statement on the Use of Placebo in Clinical Trials of Mood Disorders (2002)

A consensus conference on the use of placebo in mood disorder studies consisted of expert presentations on bioethics, biostatistics, unipolar depression, and bipolar disorder. Work groups considered evidence and presented statements to the group. Although it was not possible to write a document for which there was complete agreement on all issues, the final document incorporated input from all authors. There was consensus that placebo has a definite role in mood disorder studies. Findings of equivalence between a new drug and standard treatment in active control studies is not evidence of efficacy unless the new drug is also significantly more effective than placebo. Add-on studies in which patients are randomized to standard therapy plus the investigational drug or standard therapy plus placebo are especially indicated for high-risk patients. Mood disorders in elderly and pediatric patients are understudied, and properly designed trials are urgently needed. Research is needed on the ethical conduct of studies to limit risks of medication-free intervals and facilitate poststudy treatment. Patients must fully understand the risks and lack of individualized treatment involved in research.

A Series of Redox Active, Tetrathiafulvalene‐Based Amidopyridines and Bipyridines Ligands: Syntheses, Crystal Structures, a Radical Cation Salt and Group 10 Transition‐Metal Complexes (2004)

Amidopyridine and -2,2'-bipyridine derivatives of EDT-TTF and BTM-TTF (EDT=ethylenedithio, BTM=bis(thiomethyl), TTF=tetrathiafulvalene) have been synthesized and crystallographically characterized. In the solid state, the different supramolecular organization of all these donors results from the competition between the intermolecular interactions, that is, van der Waals, hydrogen-bonding, pi-pi stacking, and donor-acceptor interactions. The electron-donating properties of the new donors have been investigated by cyclic voltammetry measurements. A radical cation salt, formulated [EDT-TTF-CONH-m-Py](.) (+)[PF(6)](-), has been prepared by electrocrystallization and its crystal structure determined by X-ray analysis. Square planar dicationic complexes with the same donor and M(II)L(2) fragments (M=Pd, Pt, L(2)=bis(diphenylphosphino)propane (dppp) or bis(diphenylphosphino)ethane (dppe)) have been synthesized and one of them, containing the Pd(dppp) unit, has been structurally characterized. The conformation of the complex in the crystalline state is anti, with the coexistence of the dl racemic pair of enantiomers.
Bubble motion in a Hele–Shaw cell (1988)

The shapes and motion of immiscible bubbles in a Hele–Shaw cell driven by the motion of the surrounding fluid were studied. Six classes of steady shapes, some of which are remarkable, were observed. Multiple steady states exist over some ranges of parameters and the shape as a function of speed may slow hysteresis. The observed translational velocities do not agree with available theory, but some of the shapes are in qualitative agreement with those computed by Tanveer [Phys. Fluids 29, 3537 (1986)].
Electrochemically grown single-nanowire sensors (2004)

We report a fabrication technique that is potentially capable of producing arrays of individually addressable nanowire sensors with controlled dimensions, positions, alignments, and chemical compositions. The concept has been demonstrated with electrodeposition of palladium wires with 75 nm to 350 nm widths. We have also fabricated single and double conducting polymer nanowires (polyaniline and polypyrrole) with 100nm and 200nm widths using electrochemical direct growth. Using single Pd nanowires, we have also demonstrated hydrogen sensing. It is envisioned that these are the first steps towards nanowire sensor arrays capable of simultaneously detecting multiple chemical species.
Eigenvector Lookup Position Detection Method for Wireless Power Transfer of Electric Vehicles (2019)

To ensure alignment during wireless power transfer (WPT) of electric vehicles (EVs), position detection (PD) during parking is needed. In this paper, a low frequency (LF) positioning method based on eigenvector lookup is proposed, which is suitable for complex environment and easy to implement with simple algorithm. To reduce the calibration work and data storage, this paper proposes a simple method to decoupling the position and the rotation angle of vehicles by finding an eigenvector only corresponding to the position, independent of the angle. The real-time position is determined by comparing the similarity between the target vector formed by current induced voltages on sense coils and the eigenvector. A simple method of calculating rotation angle is also proposed. The feasibility of the proposed methods has been verified by simulation and experiments. The accuracy of detected position is less than 5% and the angle deviation is less than 10 degrees.
Thick-film Piezoceramic Microgenerators (2008)

Piezoelectric materials have many desirable characteristics for use in vibration energy harvesting applications. They can produce relatively high output voltages (from a few to several tens of volts) for modest levels of vibration. Many piezoelectric-based generators use piezoceramic materials such as bulk lead zirconate titanate (PZT), which are attached to an elastic element (spring/beam) by using an adhesive. Thick-film technology can offer an advantage over this approach by providing the ability to integrate fully the piezoelectric element onto the beam. This paper provides an overview of the use of piezoelectric materials in energy harvesters and discusses a novel approach to developing freestanding, thick-film piezoelectric devices
Profiling of Estrogen Up- and Down-Regulated Gene Expression in Human Breast Cancer Cells: Insights into Gene Networks and Pathways Underlying Estrogenic Control of Proliferation and Cell Phenotype (2003)

Estrogens are known to regulate the proliferation of breast cancer cells and to alter their cytoarchitectural and phenotypic properties, but the gene networks and pathways by which estrogenic hormones regulate these events are only partially understood. We used global gene expression profiling by Affymetrix GeneChip microarray analysis, with quantitative PCR verification in many cases, to identify patterns and time courses of genes that are either stimulated or inhibited by estradiol (E2) in estrogen receptor (ER)-positive MCF-7 human breast cancer cells. Of the >12,000 genes queried, over 400 showed a robust pattern of regulation, and, notably, the majority (70%) were down-regulated. We observed a general up-regulation of positive proliferation regulators, including survivin, multiple growth factors, genes involved in cell cycle progression, and regulatory factor-receptor loops, and the down-regulation of transcriptional repressors, such as Mad4 and JunB, and of antiproliferative and proapoptotic genes, including B cell translocation gene-1 and -2, cyclin G2, BCL-2 antagonist/killer 1, BCL 2-interacting killer, caspase 9, and TGFbeta family growth inhibitory factors. These together likely contribute to the stimulation of proliferation and the suppression of apoptosis by E2 in these cells. Of interest, E2 appeared to modulate its own activity through the enhanced expression of genes involved in prostaglandin E production and signaling, which could lead to an increase in aromatase expression and E2 production, as well as the decreased expression of several nuclear receptor coactivators that could impact ER activity. Our studies highlight the diverse gene networks and metabolic and cell regulatory pathways through which this hormone operates to achieve its widespread effects on breast cancer cells.
Frequency of Werner helicase 1367 polymorphism and age-related morbidity in an elderly Brazilian population (2005)

Werner syndrome (WS) is a premature aging disease caused by a mutation in the WRN gene. The gene was identified in 1996 and its product acts as a DNA helicase and exonuclease. Some specific WRN polymorphic variants were associated with increased risk for cardiovascular diseases. The identification of genetic polymorphisms as risk factors for complex diseases affecting older people can improve their prevention, diagnosis and prognosis. We investigated WRN codon 1367 polymorphism in 383 residents in a district of the city of São Paulo, who were enrolled in an Elderly Brazilian Longitudinal Study. Their mean age was 79.70 +/- 5.32 years, ranging from 67 to 97. This population was composed of 262 females (68.4%) and 121 males (31.6%) of European (89.2%), Japanese (3.3%), Middle Eastern (1.81%), and mixed and/or other origins (5.7%). There are no studies concerning this polymorphism in Brazilian population. These subjects were evaluated clinically every two years. The major health problems and morbidities affecting this cohort were cardiovascular diseases (21.7%), hypertension (83.7%), diabetes (63.3%), obesity (41.23%), dementia (8.0%), depression (20.0%), and neoplasia (10.8%). Their prevalence is similar to some urban elderly Brazilian samples. DNA was isolated from blood cells, amplified by PCR and digested with PmaCI. Allele frequencies were 0.788 for the cysteine and 0.211 for the arginine. Genotype distributions were within that expected for the Hardy-Weinberg equilibrium. Female gender was associated with hypertension and obesity. Logistic regression analysis did not detect significant association between the polymorphism and morbidity. These findings confirm those from Europeans and differ from Japanese population.
Isolation and characterization of human epicardial adipocytes: potential role in vascular inflammation (2006)

Adipose tissue is an important endocrine and secretory organ. There is growing evidence that adipocytes from different fat depots have distinct functional properties. Epicardial adipose tissue has been shown to produce inflammatory mediators, but the functional properties of isolated epicardial adipocytes (EA) have not been studied. We characterized human EA isolated from freshly harvested hearts, along with subcutaneous and perirenal adipocytes from the same donors. Differentiation from preadipocytes was associated with greatly increased adipokine and proinflammatory cytokine expression; of note, the proinflammatory mediator CD14 was expressed at 50‐fold higher levels by EA compared to preadipocytes. EA have substantial cyclooxygenase and epoxide hydrolase activity. The major COX metabolite is PGE2, which plays an important role in angiogenesis and inflammation. LPS caused increased expression of adiponectin, VEGF, and CD14 in both epicardial adipose tissue explants and cultured EA. Conditioned medium from EA (but not control medium or medium from epicardial preadipocytes or subcutaneous adipocytes) strongly promoted growth and tubule formation by human coronary artery endothelial cells. These findings suggest that EA may play an important role in promoting coronary artery inflammation and growth of vasa vasorum and collateral coronary vessels in ischemia.

Activation of an energy providing response in human keratinocytes after γ irradiation (2005)

We performed a microarray study on human differentiated HaCaT keratinocytes exposed to ionizing radiation (2 or 10 Gy). At 3 h after exposure, more than 150 known and unknown genes were found regulated in irradiated HaCaT keratinocytes. Among the genes regulated at 3 h, those involved in cell energy metabolism appeared to be the most abundant and the most responsive. Two mitochondrial ATP-synthases and several other genes involved in energy producing pathways, such as glucose metabolism, were induced, whereas many genes from energy requiring pathways were shut down. These changes in energy metabolism were confirmed both in normal primary keratinocytes and in HaCaT keratinocytes by RT-PCR and proteins studies. Moreover, measures of intracellular ATP revealed a 50% increase in keratinocytes immediately after irradiation, supporting an energy procurement response. The overall results indicate that irradiation induces an immediate burst of ATP that seems to be a general response of human differentiated keratinocytes to the radiation stress.

High field behavior of artificially engineered boundaries in melt-processed YBa2Cu3O7−δ (1998)

Artificial bulk “zero-angle” boundaries parallel to the c axis have been engineered between large melt-processed YBa2Cu3O7−δ (YBCO) grains and observed to carry a transport supercurrent at fields up to at least 5 T at 77 K. The temperature and angular dependencies of the boundary resistance have exactly the same form as those of the grains, which is evidence that the grains are intimately coupled. The limiting mechanism for current transfer across these boundaries is, therefore, not a simple weak link or Josephson effect. This joining technique is extremely promising for production of macroscopic engineering artifacts.

Incidence of reoperation and wound dehiscence in patients treated for peroneal tendon dislocations: comparison between osteotomy versus soft tissue procedures (2016)

III.
Erratum (2007)

TO THE EDITOR: We appreciate recent correspondence from Dr. Tada et al. (the Kyoto group) regarding our recent article on endoscopic management of biliary complications after living donor liver transplantation (LDLT). Our initial success rate of endoscopic management of biliary strictures after LDLT (71%, 12 of 17 patients) seems to be comparable to that by the Kyoto group (68%, 54 of 80 patients) (1). As stated in their correspondence, however, there is a considerable difference in the strategy for endoscopic management of biliary strictures between the two institutions.
Does GH replacement therapy in adult GH-deficient patients result in recurrence or increase in size of pituitary tumours? (2002)

Using a representative cohort of hypopituitary patients attending an endocrine clinic, GH replacement was not associated with an increased pituitary tumour recurrence rate. Although the results are not conclusive, in the period of observation GH had little adverse effect but longer studies are required to be certain.
A Phase-Dependent Effect That Enables Multi-Scale Moisture Measurements in Heterogeneous Substrates Using Tubular RH Sensors (2022)

A knowledge of the moisture in soils/soil litter allows for the estimation of irrigation needs or the risk of forest fire. A membrane-based humidity sensor (MHS) can measure the relative humidity (RH) as an average value in such heterogeneous substrates via its sensitive tubular silicone membrane. This RH corresponds to the moisture-dependent water potential of the substrate. For humid conditions in soil, however, the RH is already larger than 98% and hence is insensitively correlated with the water potential. For such conditions, a step-like response of the MHS was found, which occurs if the silicone membrane is wetted with water. This appears to correspond to oversaturated water vapor and must be attributed to a phase-dependent sorption mechanism of the membrane. This effect allows the expansion of the range of applications of the MHS in the detection of liquid water, such as in dew point detection. Based on this, the dependency of the measurement signal on the mean water saturation in a substrate along the tubular membrane is demonstrated. A comparison of the measurement signal with an internal reference signal according to the MHS measurement principle makes it possible to distinguish this new, saturation-dependent measurement scale from the one used for RH measurement.
Molecular profiling of innate immune response mechanisms in ventilator-associated pneumonia (2020)

Abstract Ventilator-associated pneumonia (VAP) is a common hospital-acquired infection, leading to high morbidity and mortality. Currently, bronchoalveolar lavage (BAL) is utilized in hospitals for VAP diagnosis and guiding treatment options. While BAL collection procedures are invasive, alternatives such as endotracheal aspirates (ETA) may be of diagnostic value, however, their utility has not been thoroughly explored. Longitudinal ETA and BAL were collected from 16 intubated patients up to 15 days, of which 11 developed VAP. We conducted a comprehensive LC-MS/MS based proteome and metabolome characterization of longitudinal ETA and BAL to detect host and pathogen responses to VAP infection. We discovered a diverse ETA proteome of the upper airways reflective of a rich and dynamic host-microbe interface. Prior to VAP diagnosis by microbial cultures from BAL, patient ETA presented characteristic signatures of reactive oxygen species and neutrophil degranulation, indicative of neutrophil mediated pathogen processing as a key host response to the VAP infection. Along with an increase in amino acids, this is suggestive of extracellular membrane degradation resulting from proteolytic activity of neutrophil proteases. Days prior to VAP diagnosis, detection of pathogen peptides with species level specificity in ETA may increase specificity over culture-based diagnosis. Our findings suggest that ETA may provide early mechanistic insights into host-pathogen interactions associated with VAP infection and therefore facilitate its diagnosis and treatment.
