Local Structural Disorder and Relaxation in SnO2 Nanostructures Studied by 119Sn MAS NMR and 119Sn Mössbauer Spectroscopy (2011)

We studied the local structural disorder and relaxation in different nanostructures of SnO2 by using 119Sn MAS NMR in combination with 119Sn Mössbauer spectroscopy. We investigated nanocrystalline powders with an average crystallite size of 8 nm as well as hollow spheres with a wall thickness of 3 nm and a diameter of 14 nm, and compared the results to coarse-grained materials. Whereas the uniform SnO6 octahedra in the coarse-grained material show a well-known distortion and thus large electric field gradients, the nanocrystalline SnO2 exhibits a structural relaxation leading to a distribution of local environments and more symmetric octahedra. The SnO2 hollow spheres show strong local disorder in combination with highly asymmetric environments around the Sn atoms.
Does Coronary Artery Bypass Grafting Alone Correct Moderate Ischemic Mitral Regurgitation? (2001)

CABG alone for moderate ischemic MR leaves many patients with significant residual MR and may not be the optimal therapy for most patients. Intraoperative TEE may significantly underestimate the severity of ischemic MR. A preoperative diagnosis of moderate MR may warrant concomitant mitral annuloplasty.
Application of Computing Analysis to Real-Time Railroad Track Inspection (2006)

Prevention of failures in track has continued to be a major railroad need. The problem is worsening, due to technical/cost limitations in inspection technology coupled with continuing increase in track usage/stress. Typically, railroads use an ultrasonics, on-track, computer-based, regularly scheduled, real-time inspection. However, the system development emphasis has focused primarily on the ultrasonics, while incorporating more computer science based data analysis could help gain insight and reduce the testing errors. Based upon applied research at the University of Connecticut, together with local industry, this paper describes the pattern recognition needs, and proposes a specific solution approach.

Phase-Space Optics, One Photon at a Time (2015)

The relationship between the Wigner Distribution Function and the spectral photon radiance is discussed for both physical optics and quantum optics. Computational methods and applications are surveyed, and photon-by-photon phase-space imagers are introduced.
Combination immunotherapy with Survivin and luteinizing hormone-releasing hormone fusion protein in murine breast cancer model (2018)

Recombinant Survivin and MIP suppress tumor growth significantly. Combining LHRH fusion protein with Survivin and MIP enhances tumor suppressive effects marginally which provides evidence for recombinant Survivin and LHRH fusion protein as candidates for translating the combination cancer immunotherapy approaches.
Properties of junctional and extrajunctional acetylcholine‐receptor channels in organ cultured human muscle fibres (1982)

1. Current noise, obtained during steady ionophoretic application of acetylcholine (ACh) to voltage-clamped human fibres has been analysed to derive properties of end-plate channels and also extrajunctional ACh-activated channels which are present at the muscle-tendon junction of normal fibres. In addition, ACh-receptor channels present at the end-plate and tendon region in organ cultured muscles have been compared with those in fresh muscles.2. Extrajunctional channels in the tendon region of fresh fibres have a longer mean life-time, tau, and a smaller single channel conductance, gamma, than the junctional channels. tau was 1.71 +/-0.11 msec and gamma was 25.05 +/- 1.18 pS for junctional channels; tau was 3.16 +/- 0.33 msec and gamma was 12.76 +/- 1.29 pS for extrajunctional channels.3. Properties of channels in the end-plate and tendon region were unchanged during short-term (< 7 days) organ culture at 23 or 36 degrees C. The voltage sensitivity of the mean channel life-time was similar at junctional and extrajunctional sites.4. In muscles organ cultured for 7 days at 36 degrees C, double component noise spectra were obtained at some end-plates. The fast and slow time constants underlying the noise appeared to correspond to simultaneous activation of junctional and extrajunctional channels.5. After organ culture for 3-4 weeks at 23 degrees C the mean life-time of the end-plate channels was prolonged while their single channel conductance was unchanged, tau = 3.58 +/- 0.16 msec; gamma = 22.11 +/- 0.83 pS (V(m) = -80 mV, T = 21 degrees C).6. As end-plate channel properties were unchanged in short-term cultures it was possible to assess post-junctional sensitivity by comparing miniature end-plate current (m.e.p.c.) amplitudes in both normal and myasthenia gravis affected muscles. No evidence was found for a change in post-synaptic sensitivity during organ culture at 23 degrees C of normal or myasthenia gravis muscle fibres, which seems to rule out reversible block of receptors by anti-receptor antibody as playing an important role in myasthenia gravis.
Small forces that differ with prior motor experience can communicate movement goals during human-human physical interaction (2017)

Relatively small interaction forces may communicate movement goals (i.e. "what to do and when to do it") between human partners during cooperative physical interactions. Moreover, these small interactions forces vary with prior motor experience, and may act primarily as guiding cues that convey information about movement goals rather than providing physical assistance. This suggests that robots may be able to provide meaningful physical interactions for rehabilitation using relatively small force levels.
Adaptive Voltage Control With Distributed Energy Resources: Algorithm, Theoretical Analysis, Simulation, and Field Test Verification (2010)

Distributed energy resources (DE) or distributed generators (DG) with power electronics interfaces and logic control using local measurements are capable of providing reactive power related ancillary system services. In particular, local voltage regulation has drawn much attention in regards to power system reliability and voltage stability, especially from past major cascading outages. This paper addresses the challenges of controlling DEs to regulate local voltage in distribution systems. An adaptive voltage control method has been proposed to dynamically modify control parameters to respond to system changes. Theoretical analysis shows that there exists a corresponding formulation of the dynamic control parameters; hence the adaptive control method is theoretically solid. Both simulation and field experiment test results at the Distributed Energy Communications and Controls (DECC) Laboratory confirm that this method is capable of satisfying the fast response requirement for operational use without causing oscillation, inefficiency, or system equipment interference. Since this method has a high tolerance to real-time data shortage and is widely adaptive to variable power system operational situations, it is quite suitable for broad utility application.
Management of common bile duct stones with a biliary endoprosthesis. Report on 40 cases. (1992)

Endoscopic placement of a biliary endoprosthesis has been proposed for the management of choledocholithiasis when stone extraction is difficult or considered hazardous. Over a two year period this approach was used in 40 such patients. There were 24 women and 16 men with a median age of 76 years. In seven patients with severe cholangitis no attempt was made to extract the stones. Twenty three (57.5%) patients underwent a sphincterotomy and four (10%) needle knife papillotomy. The endoprosthesis insertion was considered a temporary measure in 13 (32.5%) patients and definitive treatment in 27 (67.5%). Bile duct drainage was established in all patients. Early complications occurred in six patients (15%), but were without sequelae. Late complications developed in eight (20%) of the patients and included biliary colic (four), cholangitis (three), and cholecystitis (one). Two patients (one cholangitis and one cholecystitis) died as a consequence of the complication. Only patients without a sphincterotomy developed cholangitis. A total of eight patients (20%) underwent surgery (one as an emergency) and nine a repeat endoscopic retrograde cholangio pancreatography (two as an emergency) to clear the duct. The remaining 23 patients are asymptomatic at a median of 13 months (range five to 24 months). Biliary endoprosthesis insertion for choledocholithiasis is an important alternative means of establishing drainage in selected cases, and is probably the optimum method of management for the elderly and or debilitated patients with previous cholecystectomy. Caution must be exercised, however, in patients with an in situ gall bladder.
Plasma deposition of optical films and coatings: A review (2000)

Plasma enhanced chemical vapor deposition (PECVD) is being increasingly used for the fabrication of transparent dielectric optical films and coatings. This involves single-layer, multilayer, graded index, and nanocomposite optical thin film systems for applications such as optical filters, antireflective coatings, optical waveguides, and others. Beside their basic optical properties (refractive index, extinction coefficient, optical loss), these systems very frequently offer other desirable “functional” characteristics. These include hardness, scratch, abrasion, and erosion resistance, improved adhesion to various technologically important substrate materials such as polymers, hydrophobicity or hydrophilicity, long-term chemical, thermal, and environmental stability, gas and vapor impermeability, and others. In the present article, we critically review the advances in the development of plasma processes and plasma systems for the synthesis of thin film high and low index optical materials, and in the control of plasma–surface interactions leading to desired film microstructures. We particularly underline those specificities of PECVD, which distinguish it from other conventional techniques for producing optical films (mainly physical vapor deposition), such as fabrication of graded index (inhomogeneous) layers, control of interfaces, high deposition rate at low temperature, enhanced mechanical and other functional characteristics, and industrial scaleup. Advances in this field are illustrated by selected examples of PECVD of antireflective coatings, rugate filters, integrated optical devices, and others.
[Irradiation of the para-aortic ducts. Presentation of an radiation technic with a largely fixed patient's position]. (1983)

An irradiation planning program has been developed at the Radiologic University Hospital of Graz which allows an interactive optimization of the energy dose distribution of a Co-60 radiation. This program is running in a minicomputer of type DEC PDP-11/34 under the operation system RSX-11. With the aid of this system, a technique has been developed for irradiating the para-aortic lymph canals which complies with theoretical as well as practical optimization criteria. These optimization criteria are defined, and the usefulness of this irradiation technique is compared with a conventional method and demonstrated on the clinical example.
Physicochemical and Structural Properties of 8S and/or 11S Globulins from Mungbean [Vigna radiata(L.) Wilczek] with Various Polypeptide Constituents (2010)

Two kinds of globulins, 8S and 11S globulins, with various polypeptide constituents, were well fractionated from acid- and salt-extracted mungbean globulins using DEAE-Sepharose fast flow column chromatography. The physicochemical and conformational properties, including amino acid composition, surface charge and hydrophobicity, free sulfhydryl group (SH) and disulfide bond (SS) contents, protein solubility, thermal and emulsifying properties, as well as secondary and tertiary conformations, were evaluated. Remarkable differences in polypeptide composition, surface charge and hydrophobicity, SS contents, protein solubility, thermal and emulsifying properties, and secondary and tertiary conformations were observed between 8S and 11S globulins. The physicochemical and conformational properties of the vicilins also varied with the heterogeneity of their polypeptides, but to a relatively limited extent. The emulsifying ability of these globulins was distinctly dependent on their protein solubility (or net charge), surface hydrophobicity and polypeptide heterogeneity. The thermal properties were similar among various vicilins, but distinctly different between the vicilins and 11S globulins. The circular dichrosim spectral analyses revealed that there were no marked differences in secondary and tertiary conformations between various vicilins, but the secondary, tertiary and quaternary conformations of 11S globulins were much more unordered and flexible than the vicilins. These results suggested good relationships between the physicochemical properties and conformational features of these globulins from mungbean, which could be useful for the utilization of these proteins in the food industry, and providing a working direction of mungbean breeding or protein engineering to improve its physicochemical properties.
Chemotactic Response Toward Chemokines and Its Regulation by Transforming Growth Factor-β1 of Murine Bone Marrow Hematopoietic Progenitor Cell-Derived Different Subset of Dendritic Cells (1999)

Dendritic cells (DCs) are highly specialized antigen-presenting cells that distribute widely in all organs. DCs initiate the primary immune response and activate naive T cells and B cells responsible for the acquired immunity. In this study, CCR7 mRNA was proved to be expressed in DCs and their precursors derived from murine bone marrow-derived hematopoietic progenitor cells (HPCs), whereas CCR1 mRNA was expressed in both CD11b-/dullCD11c+ and CD11b+hiCD11c+ DC precursors. CCR6 mRNA was not detected in any murine DC populations. In agreement with the chemokine receptor mRNA expression by each population in the DC differentiation pathway, SLC (also termed as MIP-3beta), one of the ligands for CCR7, strongly and selectively chemoattracted both CD11b-/dullCD11c+ and CD11b+hiCD11c+ DC precursors (days 6 to 7) and more mature DCs (days 13 to 14). We have recently found that transforming growth factor-beta1 (TGF-beta1), a cytokine that is essential for the appearance of Langerhans cells in the skin, polarizes murine HPCs to generate Langerhans-like cells through monocyte/macrophage differentiation pathway. We observed here that TGF-beta1 not only inhibited the expression of CCR7 in DCs and DC precursors derived from HPCs, but also inhibited the migration of these cells in response to SLC. This is the first report describing the chemokine and chemokine receptors responsible for murine DC migration and downregulation of DC migration by TGF-beta1.
Therapy of patients with the high risk of arterial hypertension with the use of telmisartan (2019)

The use of telmisartan in complex therapy improves the quality of life according to the EQ-VAS questionnaire by 25 points after 12 months of therapy, contributes to lowering blood pressure in 96% of patients, reduc‑ ing myocardial hypertrophy, endothelial dysfunction and severity of ischemic manifestations (reducing the need for nitroglycerin intake to an average of 0,5 inhalations, as well as a decrease in the ST segment depression of 40% after 12 months of therapy).
Amplitude modulation mode locking of lasers by regenerative feedback (1991)

We analyze the performance of regenerative feedback mode locking using intracavity amplitude modulation (AM). Regenerative feedback is predicted to improve the stability of AM mode locking especially at low and moderate repetition rates and short pulse durations. We report on AM regenerative-feedback mode locking of a continuous wave Nd:glass laser. The generated train of 8 ps pulses has an excellent long-term stability and is completely free of relaxation oscillation instabilities inherent in conventional AM mode locking.
ON THE OPERATION OF THE DISCHARGE CHAMBER (1961)

The tracks observed in the discharge chamber have a slight S shape and some exhibit branches. It was suggested that the first type of track is due to streams channeled along the ionized tracks, to real and proper filamentshaped discharges. The second is due to a local avalanche multiplication of the electrons initially formed for alpha particles. The design of the discharge chamber constructed to conform these assumptions is given in some detail, and the results are described. (J.S.R.)
Analysis, modeling and generation of self-similar VBR video traffic (1994)

We present a detailed statistical analysis of a 2-hour long empirical sample of VBR video. The sample was obtained by applying a simple intraframe video compression code to an action movie. The main findings of our analysis are (1) the tail behavior of the marginal bandwidth distribution can be accurately described using “heavy-tailed” distributions (e.g., Pareto); (2) the autocorrelation of the VBR video sequence decays hyperbolically (equivalent to long-range dependence) and can be modeled using self-similar processes. We combine our findings in a new (non-Markovian) source model for VBR video and present an algorithm for generating synthetic traffic. Trace-driven simulations show that statistical multiplexing results in significant bandwidth efficiency even when long-range dependence is present. Simulations of our source model show long-range dependence and heavy-tailed marginals to be important components which are not accounted for in currently used VBR video traffic models.
Mechanism of Neutralization of Herpes Simplex Virus by Antibodies Directed at the Fusion Domain of Glycoprotein B (2013)

For herpesviruses, such as HSV, entry into a target cell involves transfer of the capsid-encased genome of the virus to the target cell after fusion of the lipid envelope of the virus with a lipid membrane of the host. Virus-encoded glycoproteins in the envelope are responsible for fusion. Antibodies to these glycoproteins are important biological tools, providing a way of examining how fusion works. Here we used electron microscopy and other techniques to study a panel of anti-gB antibodies. Some, with virus-neutralizing activity, impair gB-lipid association. We also generated a peptide antibody against one of the gB fusion loops; its properties provide insight into the way the fusion loops function as gB transits from its prefusion form to an active fusogen.
Methods to Estimate the Size and Shape of the Unaccommodated Crystalline Lens In Vivo (2012)

The regressions presented in this article offer a valuable alternative in case no measured lens biometry values are available; however care must be taken for possible outliers.
Kidney Function, ACE-Inhibitor/Angiotensin Receptor Blocker Use, and Survival Following Hospitalization for Heart Failure: A Cohort Study (2018)

Patients with HF and reduced eGFR at time of hospital discharge were less likely to receive ACE-I/ARB despite these medications being associated with lower mortality independent of eGFR. These findings demonstrate the need for further research on strategies for safe use of ACE-I and ARB in patients with HF and kidney disease.
Acne counseling to improve adherence. (2008)

Acne causes substantial social, emotional, and psychological effects in both adolescents and adults. Although current therapies can effectively treat the disease and its related effects, adherence to these treatment regimens often is poor. Misconceptions about the cause of acne, unrealistic treatment expectations, the chronic and partially asymptomatic nature of the disease, difficulty incorporating treatment into daily activities, and the need for long-term therapy contribute to overall adherence. To improve adherence, physicians must counter these factors with skilled counseling; consideration of the patient's perspective; effective means of educating the patient; and simple, effective, tolerable regimens that are compatible with the patient's lifestyle.
r-GAT: Relational Graph Attention Network for Multi-Relational Graphs (2021)

Graph Attention Network (GAT) focuses on modelling simple undirected and single relational graph data only. This limits its ability to deal with more general and complex multi-relational graphs that contain entities with directed links of different labels (e.g., knowledge graphs). Therefore, directly applying GAT on multi-relational graphs leads to sub-optimal solutions. To tackle this issue, we propose r-GAT, a relational graph attention network to learn multi-channel entity representations. Specifically, each channel corresponds to a latent semantic aspect of an entity. This enables us to aggregate neighborhood information for the current aspect using relation features. We further propose a query-aware attention mechanism for subsequent tasks to select useful aspects. Extensive experiments on link prediction and entity classification tasks show that our r-GAT can model multi-relational graphs effectively. Also, we show the interpretability of our approach by case study.
Multidisciplinary Senior Design Using Software Defined Radio (2020)

Multidisciplinary projects involving electrical engineering (EE) and computer science (CS) students are both exciting and difficult to create. We have created a year-long project based on software-defined radio (SDR). The combination of software and hardware makes SDR an excellent choice for senior projects. Senior CS students have enough programming experience to handle the software development; EE seniors have sufficient knowledge to understand the basics of radio, signal processing, and circuit design. The integration of a complex hardware and software system provides an excellent educational experience. In this paper, we describe the senior project courses, the pedagogical goals, and how it supports our ABET course outcomes.
Modification of l-Isoleucyl-tRNA Synthetase with l-Isoleucyl-Bromomethyl Ketone. The Effect on the Catalytic Steps (1977)

The rapidly reacting cysteine-sulfhydryl group of L-isoleucyl-tRNA synthetase has been specifically alkylated with L-isoleucyl-bromomethyl ketone [Rainey, P., Holler, E. & Kula, M.-R. (1976) Eur. J. Biochem. 63, 419-426]. We have now investigated the catalytic and substrate binding properties of the modified protein by radioactive and fluorescence techniques. The rate constants for the transfer of AMP and isoleucine from the protein - adenylate complex to form ATP or Ile-tRNAIle were only 3% of those for native enzyme, whereas the rate constant for the formation of adenylate was essentially unchanged. The tendency to form synthetase - substrate complexes remained almost unchanged with the exception of L-isoleucine which exhibited a 20-fold reduction. Similarly, complex formation of L-isoleucinol together with its synergistic coupling to complex formation of ATP was partially inhibited. The results rule out the essential participation of the rapidly alkylatable cysteine-sulfhydryl group during catalysis.
