Multi-Task Learning of Graph-based Inductive Representations of Music Content (2021)

Music streaming platforms rely heavily on learning meaningful representations of tracks to surface apt recommendations to users in a number of different use cases. In this work, we consider the task of learning music track representations by leveraging three rich heterogeneous sources of information: (i) organizational information (e.g., playlist co-occurrence), (ii) content information (e.g., audio &amp; acoustics), and (iii) music stylistics (e.g., genre). We advocate for a multi-task formulation of graph representation learning, and propose MUSIG: Multi-task Sampling and Inductive learning on Graphs. MUSIG allows us to derive generalized track representations that combine the benefits offered by (i) the inductive graph based framework, which generates embeddings by sampling and aggregating features from a node's local neighborhood, as well as, (ii) multi-task training of aggregation functions, which ensures the learnt functions perform well on a number of important tasks. We present large scale empirical results for track recommendation for the playlist completion task, and compare different classes of representation learning approaches, including collaborative filtering, word2vec and node embeddings as well as, graph embedding approaches. Our results demonstrate that considering content information (i.e.,audio and acoustic features) is useful and that multi-task supervision helps learn better representations.
Assessment of a superparamagnetic iron oxide (ami‐25) as a brain contrast agent (1990)

We have applied a superparamagnetic iron oxide formulation (AMI-25, Advanced Magnetics, Inc., Cambridge, MA) to image the cerebral vasculature. Contrast-enhanced images of normal anesthetized rats demonstrated excellent gray/white matter differentiation, consistent with known differences in blood perfusion, and cerebrospinal fluid spaces were clearly seen. Alterations in normal perfusion patterns due to barbiturate anesthesia and ischemia were clearly visible. We propose the use of this agent as an adjunct to MRI for the imaging of conditions with perfusion abnormalities.
Cyclin D1 repression of nuclear respiratory factor 1 integrates nuclear DNA synthesis and mitochondrial function (2006)

Cyclin D1 promotes nuclear DNA synthesis through phosphorylation and inactivation of the pRb tumor suppressor. Herein, cyclin D1 deficiency increased mitochondrial size and activity that was rescued by cyclin D1 in a Cdk-dependent manner. Nuclear respiratory factor 1 (NRF-1), which induces nuclear-encoded mitochondrial genes, was repressed in expression and activity by cyclin D1. Cyclin D1-dependent kinase phosphorylates NRF-1 at S47. Cyclin D1 abundance thus coordinates nuclear DNA synthesis and mitochondrial function.

10 Jahre Stuttgarter Glasschale ‐ eine Zwischenbilanz (2014)

Abstract Die Stuttgarter Glasschale wurde im Jahre 2004 als Prototyp gebaut, um die statische Effizienz und die ästhetische Qualität von Glasverklebungen zu untersuchen. Die von den Autoren für den Prototyp entwickelte Klebetechnik ermöglicht die Weiterleitung von Kräften zwischen den Glasscheiben in Form von Stossfugen und damit die Aufnahme von Herstellungs‐ sowie Montagetoleranzen. Was als temporärerer Prototyp entwickelt wurde, steht seit nunmehr 10 Jahren am ILEK der Universität Stuttgart und wird kontinuierlich beobachtet und evaluiert. Es konnte aufgezeigt werden, dass Windlasten, symmetrische und asymmetrische Schneelasten, UV‐Belastungen sowie die Alterungsprozesse der Verklebung auf Polymerbasis die Funktionsfähigkeit der Verklebungen bzw. die Tragfähigkeit der Schale bis dato nicht beeinträchtigt haben. Der vorliegende Artikel hält Rückschau auf die vergangenen zehn Jahre und fragt nach der Zukunft von Glasverklebungen. The Stuttgart Glass Shell 10 years later – retrospect and perspectives. The Stuttgart Glass Shell was built in 2004 at the ILEK, University of Stuttgart with the aim of analyzing the structural efficiency as well as the aesthetical quality that can be achieved by combining structural use of glass with adhesives as joining system. The prototype was planned as a temporary structure, but now it has been standing for 10 years under permanent monitoring at the ILEK. Wind, symmetrical and asymmetrical snow loadings, UV‐radiations, as well as aging processes have not influenced the performance of the adhesive joints or the load‐bearing capacity of the shell. Ten years therefore seem to be a reasonable lapse of time on the one hand to look back and on the other to give a perspective about the future development of adhesive joints.
Localizing a mobile robot with intrinsic noise (2012)

Robot localization is a key barrier to providing natural interaction between 3D virtual characters, human users and mobile robots. Knowing where the robot is, relative to a known world-frame, is essential to directed gestures, gazes and expressions between the robot and the other real and virtual participants in a telepresence system. The intrinsic noise of robots is a flexible and robust, yet under-examined, source for localization information. Sounds that likely localize the robot are identified and separated from background noises using a support vector machine. The resulting sound-bearing data is combined with robot odometry using a particle filter. Experiments conducted in a noisy office environment show substantial improvement over odometry alone.
A Novel CMOS High-Power Terahertz VCO Based on Coupled Oscillators: Theory and Implementation (2012)

We introduce a novel frequency tuning method for high-power terahertz sources in CMOS. In this technique, multiple core oscillators are coupled to generate, combine, and deliver their harmonic power to the output node without using varactors. By exploiting the theory of nonlinear dynamics, we control the coupling between the cores to set their phase shift and frequency. Using this method, two high-power terahertz VCOs are fabricated in a 65 nm LP bulk CMOS process. The first one has a measured output power of 0.76 mW at 290 GHz with 4.5% tuning range and the output power of the second VCO is 0.46 mW at 320 GHz with 2.6% tuning range. The output power of these signal sources is 4 orders of magnitude higher than previous CMOS VCOs and is even higher than VCOs implemented in compound semiconductors with much higher cut-off frequencies.
Force and Deformation Measurement on Low Aspect Ratio Membrane Airfoils (2013)

This paper investigates the effects of pre-strain and cell aspect ratio on free trailing edge, aspect ratio two, membrane wings at low Reynolds number (Re ~ 50,000). At these conditions, the membrane visually vibrates. Of particular interest is the comparison of the membrane wing aerodynamic performance to rigid models fabricated in the shape of the time-averaged membrane deformation. Three pre-strain levels, 1%, 2% and 4%, were applied to flat membranous wings with one, two and three cells. Force and deformation measurements were performed in a low speed wind tunnel. From digital image correlation results, the rigid, time-averaged deformation wings were fabricated using three-dimensional printing. The aerodynamic loads for the printed wings were acquired at the same test conditions as membranous wings to extract the dynamic and static benefits of flexibility. In general, the membrane wings outperformed the printed wings at both pre-stall and stall conditions.

Natural Sound Change and Its Patterns: The Case of the Lateral Approximant l (2012)

In light of Chinese historical phonology, modern dialects, languages of Chinese minorities and field phonetics, this paper discusses (1) the development of the Yi -initial words from Old Chinese to Middle Chinese, (2) the development of the Lai-initial words from Middle Chinese to modern dialects, (3) the phonological behavior of segment l in different syllabic positions from the perspective of evolutionary phonology. Such evolutionary developments as palatalization, velarization, nasalization, labiodentalization, fricativization, strengthening and so on can be identified for approximant l . This provides an important panchronic and typological perspective for the interpretation of both diachronic changes and synchronic variation.

High efficiency Ca2+ transport by the sarcoplasmic reticulum Ca2(+)-ATPase in the absence of the 53-kilodalton glycoprotein. (1990)

Although the Ca2(+)-ATPase is the predominant protein species of the skeletal sarcoplasmic reticulum membrane, the functional significance of other minor protein species remains unresolved. The proposition has been tested that the membrane-bound 53-kDa glycoprotein (GP-53) may be required or significantly involved in regulating the coupling of ATP hydrolysis to Ca2+ transport by the Ca2(+)-ATPase. Ca2(+)-ATPases originating from preparations with and without GP-53 were reconstituted into phosphatidylcholine liposomes, and Ca2+ uptake and pumping efficiency were determined. The reconstituted Ca2+ pump from all preparations transported Ca2+ with high efficiency (Ca2+:ATP greater than 1.5). The results demonstrate that GP-53 is not required to couple ATP hydrolysis to Ca2+ transport. Additionally, the observed high coupling efficiency is inconsistent with GP-53 functioning as a substantial positive regulator of coupling.
Electrocoagulative Surgical Procedure for Treatment of Conjunctivochalasis (2012)

The purpose of this study was to present a new procedure to treat symptomatic conjunctivochalasis (CCh) and to evaluate its efficacy. Forty-two patients with symptomatic CCh refractory to medical management were included on this study. Twenty-two patients (n = 32, eyes; n = 14 women and n = 8 men) underwent the new electrocoagulation procedure (group I). Twenty patients (n = 27 eyes; n = 11 women and n = 9 men) underwent crescent-shaped conjunctiva resection (group II). Ocular surface disease index (OSDI) was used to evaluate ocular symptoms. There was a significant difference in mean and SD operation time between group I (8.67 ± 2.07 minutes) and group II (20.45 ± 3.98 minutes; P < 0.0001). OSDI scores (mean ± SD) were significantly lower in group I (28.38 ± 3.14) than group II (31.62 ± 3.17) at postoperative week 2 (P = 0.0004). No differences in OSDI scores were found between the 2 groups at postoperative week 4 (P = 0.1749) or 8 (P = 0.1483). OSDI scores were significantly lower at postoperative week 8 than at baseline in both group I (P = 0.0002) and group II (P = 0.0011). Electrocoagulation of the conjunctiva can successfully treat symptomatic CCh with earlier symptomatic attenuation and less operation time than traditional conjunctiva resection.
Application of the 2,4,6-trinitrobenzene-1-sulfonic acid (tnbs) method for determination of available lysine in maize seed. (1982)

This paper reports on a modified procedure for determination of lysine in maize seeds. The modified procedure was economical, accurate and fast, and has been used to determine the available lysine in large numbers of maize grains. Protein sufficiently representative of total protein was extracted from samples ground in a water-cooled grinder. It was proposed that for samples with more than 15% protein the volume of NaOH-ETOH extractant be doubled. For maize samples with 15-30% oil content, 20ml of acetone was used for fat extraction, as opposed to 15 ml of acetone used for samples with less than 15% oil content. The sub-sampling variation was not significant for the modified 2, 4, 6-trinitrobenzene-1-sulfonic acid (TNBS) procedure. The correlation coefficient between lysine values determined by the amino acid analyser and the TNBS method for 90 opaque-2 samples was high (r=0.806). The coefficient of variation for TNBS was 6.5% against 12.6% for the microbiological assay (MBA), indicating that more variation was associated with the MBA than with the TNBS method.
A primal-dual augmented Lagrangian (2010)

Nonlinearly constrained optimization problems can be solved by minimizing a sequence of simpler unconstrained or linearly constrained subproblems. In this paper, we consider the formulation of subproblems in which the objective function is a generalization of the Hestenes-Powell augmented Lagrangian function. The main feature of the generalized function is that it is minimized with respect to both the primal and the dual variables simultaneously. The benefits of this approach include: (i) the ability to control the quality of the dual variables during the solution of the subproblem; (ii) the availability of improved dual estimates on early termination of the subproblem; and (iii) the ability to regularize the subproblem by imposing explicit bounds on the dual variables. We propose two primal-dual variants of conventional primal methods: a primal-dual bound constrained Lagrangian (pdBCL) method and a primal-dual ℓ 1 linearly constrained Lagrangian (pdℓ 1LCL) method. Finally, a new sequential quadratic programming (pdSQP) method is proposed that uses the primal-dual augmented Lagrangian as a merit function.
The Effects Of Alcohol-free 0.12% W/N Chlorhexidine Gluconate Mouthrinse On Oral Health (2001)

CWorhexidine gluconate, a dicationic bisbiguanide agent, contains anti-plaque properties. Most chlorhexidine gluconate mouth rinses presently available contain alcohol in varying concentrations. The role of alcohol in these mouth rinses is to act as a preservative and solvent although it may have deleterious effects on the oral epithelium on long term usage. Recently, an alcohol-free 0.12 % w/v chlorhexidine gluconate mouth rinse (Oradex?) has become available in Malaysia. This clinical study is aimed at determining the effects of this alcohol-free product compared to a placebo. A group of 60 meticulously screened subjects were assigned into two groups of 30 each. The first group started using the test product for 2 weeks followed by a washout period of 4 weeks. After this duration, this group used the placebo for a further 2 weeks. The 2nd group underwent similar protocol as the 1st except that this group started with the placebo. Measurements consisting of the following scores were recorded at baseline and after 2 weeks for each group: Plaque, Gingivitis: Papillary Bleeding, Stain and Calculus. Full mouth prophylaxis was carried out for all subjects after measurements at baseline as well as after the 2-week period. They were told to rinse with 15 ml of the designated mouth rinse twice daily for thirty seconds each after tooth brushing. The results of this study indicated that there was significant improvement in the plaque, gingival and papilla bleeding scores compared to the placebo. Stain and calculus scores were significantly increased for the test product when compared to the placebo. In conclusion, this study showed that alcohol-free 0.12 % w/v chlorhexidine gluconate mouth rinse is effective in reducing plaque and gingivitis but causes staining and calculus formation.
EXPRESSION OF CHEMOKINE GENES DURING REJECTION AND LONG-TERM ACCEPTANCE OF CARDIAC ALLOGRAFTS1 (1997)

Chemokines are cytokines with chemoattractant properties for leukocytes. They may play a critical role in directing leukocytes to graft sites and in amplifying intragraft inflammation during rejection. Previous studies have tested the intragraft expression of chemokine genes during the rejection of allogeneic skin grafts in mice. In the current study, we used a heterotopic heart transplant model in mice to test the intragraft expression of these genes in nonrejecting cardiac isografts, rejecting cardiac allografts, and cardiac allografts that were accepted due to immunosuppression with gallium nitrate. With the exception of low levels of interleukin-1beta and JE, intragraft expression of the the proinflammatory cytokine genes was not observed in either isografts or native heart. Two distinct patterns of chemokine mRNA were observed in the rejecting cardiac allografts. Intra-allograft expression of interleukin-1beta, interferon-gamma-inducible protein, JE, and KC was prominent by day 3 after transplantation. The expression of macrophage inflammatory protein (MIP)-1alpha, MIP-1beta, and regulated upon activation, normal T cell expressed and secreted (RANTES) was at low or undetectable levels at day 3 after transplantation but at high levels by day 8 after transplantation. Sixty days after transplantation, intra-allograft expression of chemokines in hearts from gallium nitrate-treated recipients indicated low levels of MIP-1alpha, MIP-1beta, and KC but high levels of interferon-gamma-inducible protein and RANTES.

A Tablet Interface for a Direct Vision Teleoperation of an Excavator for Urban Construction Work (2017)

Recent years, worker shortage in the field of urban construction is becoming a bigger issue. To solve this problem, direct-vision remote control of a construction machine can be an effective solution where a worker can play not only the role of an operator but also the role of manual laborer. Authors propose a new direct-vision remote control system for an excavator using a tablet device. In the system, the graphical user interface (GUI) enables an operator to control an excavator by using various multiple-fingers action. An excavator teleoperation system has been developed to conduct an experiment. In the usability-testing experiment, the usability of the proposed system has been evaluated and its performance has been compared with a GUI that simulates an interface of conventional machine levers. The experimental results have verified the advantage of the proposed system.
A Fatigue Model for Spur Gear Contacts Operating Under Mixed Elastohydrodynamic Lubrication Conditions (2012)

This paper presents a model to predict the crack formation fatigue lives of spur gear contacts operating under mixed lubrication conditions where surface roughnesses introduce intermittent metal-to-metal contacts and severe stress concentrations. The proposed model consists of several submodels, including (i) a gear load distribution model to determine the normal tooth force distribution along the tooth surface, incorporating any profile modifications and manufacturing deviations, (ii) a mixed elastohydrodynamic lubrication model customized to handle transient contact conditions of gears, (iii) a stress formulation that assumes the plane strain condition to compute the transient elastic stress fields on and below the tooth surface induced by the mixed lubrication surface pressure and shear stress distributions, and (iv) a multi-axial fatigue model to predict the crack nucleation life distribution. The proposed spur gear fatigue model is used to simulate the contacts of gear pairs having different surface roughness amplitudes. The predictions are compared to the measured gear fatigue stress-life data for each surface condition to assess the model accuracy in the prediction of the crack nucleation fatigue lives as well as the location of the critical failure sites.
Suboptimal activation of melanoma infiltrating lymphocytes (TIL) due to low avidity of TCR/MHC-tumor peptide interactions. (1996)

Coculture of melanoma cells and T cell clones derived from tumor-infiltrating lymphocytes (TIL) generally results in lysis of the antigen-bearing tumor cells but to inefficient proliferation and IL-2 secretion by responder T cells. This suboptimal activation is classically explained by an inability of tumor cells to provide costimulatory signals. Here we analyzed the responses to synthetic peptides of HLA-A2.1-restricted CTL clones specific for melanoma antigens MART-1 and NA17-A. We showed that peptide concentrations ranging from 1 pM to 10 nM efficiently sensitized the peptide transporter-deficient T2 cells to lysis. T2 cells pulsed with melanoma peptides also induced TIL proliferation and detectable secretion of IL-2, IFN-gamma and GM-CSF, but only for peptide concentrations 10- to 10,000-fold higher than those required for lysis. Hence this suggests that partial triggering of TIL clones by melanoma cells could be due to expression of appropriate MHC-peptide complexes at subthreshold levels. In support of this, we showed that melanoma cells, unable to trigger IL-2 secretion, developed this ability when incubated with the appropriate peptide. These results indicate that the level of antigens expressed on melanoma tumors critically affects TIL activation status and thus, the efficiency of specific immune reactions mediated by these cells.
