Identifying Cover Songs Using Information-Theoretic Measures of Similarity (2015)

This paper investigates methods for quantifying similarity between audio signals, specifically for the task of cover song detection. We consider an information-theoretic approach, where we compute pairwise measures of predictability between time series. We compare discrete-valued approaches operating on quantized audio features, to continuous-valued approaches. In the discrete case, we propose a method for computing the normalized compression distance, where we account for correlation between time series. In the continuous case, we propose to compute information-based measures of similarity as statistics of the prediction error between time series. We evaluate our methods on two cover song identification tasks using a data set comprised of 300 Jazz standards and using the Million Song Dataset. For both datasets, we observe that continuous-valued approaches outperform discrete-valued approaches. We consider approaches to estimating the normalized compression distance (NCD) based on string compression and prediction, where we observe that our proposed normalized compression distance with alignment (NCDA) improves average performance over NCD, for sequential compression algorithms. Finally, we demonstrate that continuous-valued distances may be combined to improve performance with respect to baseline approaches. Using a large-scale filter-and-refine approach, we demonstrate state-of-the-art performance for cover song identification using the Million Song Dataset.
20.3: Super‐High Luminance Light‐Source Device with Carbon Nanotube Emitter (2001)

Abstract Carbon nanotubes (CNTs) have been attracting considerable attention as field emitters. An excellent performance of carbon‐nanotubes as field‐emitters was demonstrated using a high‐voltage FED element at Society for Information Display (SID) in 1998 where a lighting element for outdoor large size display and a flat panel were presented with the screen printed nanotube cathode. After that, we reported experimental results of a light source tube which was able to be emitted luminous flux of more than 1000lm in prospect at International Display Workshops'00 (IDW'00). In this paper, we described a light‐source device which performed super‐high luminance with special multi‐walled nanotubes (MWNTs) called nanografiber (NGF) as field emitters. The electrodes passed through electrons was improved for more uniform landing to the phosphor screen. X‐ray shield and cooling for phosphor screen were investigated for a practical use and life‐time confirmation. The device was experimentally applied to one of projection displays with liquid crystal display (LCD) as light sources. NGF cathodes have been tested under dc driving condition with high current and high anode voltage(25–30kV) against high voltage ion bombardment. The degradation of phosphors has been tested to maintain super‐high luminance under high density electron irradiation and efficient cooling.
Autologous Cultured Skin Substitutes Reduce Requirements for Split-thickness Skin Autograft in Treatment of Excised, Full-Thickness Burns (2006)

Rapid and effective closure of full-thickness burn wounds remains a limiting factor in burns of greater than 50% of the total body surface area (TBSA). Hypothetically, cultured skin substitutes (CSS) consisting of autologous cultured keratinocytes and fibroblasts attached to collagen-based sponges may reduce requirements for donor skin, numbers of grafting procedures, and time of intensive care during hospitalization. To test this hypothesis, CSS were prepared from split-thickness skin biopsies collected after enrollment of 54 burn patients by Informed Consent into a study protocol approved by the local Institutional Review Board. CSS and split-thickness skin autograft (AG) were applied in a matched-pair design with each patient serving as their own control. Data collection consisted of photographs, area measurements of donor skin and healed wounds after grafting (n=54), and qualitative outcome by the Vancouver Scale for burn scar (n=47). Data are expressed below as: A) % area closed at post-operative day (POD)...

<title>Visual recognition of blurred shapes</title> (1994)

The human recognition probabilities of blurred rotationally symmetric shapes have been studied using computer generated images displayed in a 128 X 128 pixel area on a TV monitor. The shapes employed included a series of regular polygons, crosses, and rectangles. These were blurred by convolution with two dimensional Gaussian functions which had standard deviations ranging from 0 to 29. Images of the blurred shapes were presented to observers in a random order and with a random extent of blurring. After each presentation the observer decided which of the shapes was most likely to be represented by the image displayed on the screen. A correlation has been found between the extent by which a shape may be blurred before it ceases to be recognizable and the difference between the original shape and a circle of the same area. This correlation has been expressed as an empirical relationship between the probability of recognition and the standard deviation of the Gaussian blurring function when the latter is normalized by a function which depends on the original shape and the one it is being confused with. This relationship has been applied to a series of irregular shapes to predict the amount of blurring required before they too cease to be recognizable. These predictions have been compared to experimental observations for the irregular shapes considered. The probability of recognizing an image may be used as a measure of image quality. The empirical relationship derived from this work could, therefore, form the basis of a new objective performance measure for thermal imaging systems.
Development of a civil infrastructure resilience assessment framework and its application to a nuclear power plant (2020)

Recent disruptive events, such as earthquakes or floods, have caused severe damage to civil infrastructure systems. Thus, there is a need to extend the focus of traditional design practices to include resilience-based design approaches which can help in defining preventive actions and measures to mitigate the consequences caused by such disruptive events. This paper presents a Civil Infrastructure Resilience Assessment Framework (CIRAF) to assess the seismic fragility and resilience of a single or multiple interconnected civil infrastructure systems following a disruptive event. Once the information regarding the infrastructure system, hazards, fragility functions, component's damage state correlation, recovery models, and upgrade models are identified, then the framework can be used to quantify the loss of functionality, recovery time, repair cost, and overall resilience using a Bayesian Network approach. A state-of-the-art engineering tool is also developed using the framework that would enable the stakeholders to compare different upgrade strategies through an easy to use web interface and thus easing the decision-making process. A case study of a hypothetical nuclear power generation system is used to assess the seismic fragility and resilience using the proposed framework.
Physical and Electrochemical Characterization of Nanocomposite Membranes of Nafion and Functionalized Silicon Oxide (2007)

Nafion nanocomposite membranes were prepared from Nafion 117 and a systematic range of organically functionalized silicon alkoxide precursors using an in situ sol gel synthesis technique. The physical structure of the resulting nanocomposite membranes were characterized using small and wide-angle X-ray scattering, small angle neutron scattering, positron annihilation lifetime spectroscopy, and transmission electron microscopy. A structural model is proposed for three typical nanocomposite membranes (Nafion-TEOS, Nafion-MPTMS and Nafion-MPMDMS). The proton and methanol transport properties of the membranes included in the model were evaluated by impedance spectroscopy and pervaporation experiments, respectively, and correlated to their composite microstructure. In particular, this model explains the increased selectivity for transport over protons for nanocomposite membranes produced using (3-mercaptopropyl)methyldimethoxysilane as the silicon alkoxide precursor, which is more than six times higher than that of Nafion 117.

Monomeric/dimeric forms of Fgf15/FGF19 show differential activity in hepatocyte proliferation and metabolic function (2021)

Human Fibroblast Growth Factor 19 (FGF19) and mouse ortholog Fgf15 play similar roles in liver regeneration and metabolism via the activation of Fgfr4/b-klotho (Klb). Monomeric FGF19 and dimeric Fgf15 are both necessary for liver regeneration and proper bile acid (BA) metabolism. FGF19 elicits stronger effects than Fgf15 on glucose and fatty acid metabolism and only FGF19 induces hepatocellular carcinoma (HCC). However, inhibiting FGF19/FGFR4 signaling in HCC patients is associated with toxicity due to elevated BA levels. Here, we examine the structure/function relationship in Fgf15/FGF19 to better understand the molecular basis for their distinct functions. We demonstrate that FGF19 is a more effective activator of Fgfr4 and of downstream signaling (Erk, Plcg1) than Fgf15. Furthermore, we use site-directed mutagenesis to show that the presence or absence of an unpaired cysteine in Fgf15/19 modulates ligand structure and determines the ability of these molecules to induce hepatocyte proliferation, with monomers being more potent activators. Consistent with these findings, an engineered dimeric variant of FGF19 is less effective than wild-type FGF19 at inducing liver growth in cooperation with the Wnt-enhancer RSPO3. In contrast to effects on proliferation, monomeric and dimeric ligands equally inhibited the expression of Cyp7a1, the enzyme catalyzing the rate limiting step in BA production. Thus, structure and function of Fgf15/FGF19 are intricately linked, explaining why FGF19, but not Fgf15, induces liver tumorigenesis. Our data provide insight into FGF19/FGFR4 signaling and may inform strategies to target this pathway while limiting on-target toxicity due to dysregulation of BA production or induction of hepatocyte proliferation.
Can an 18-point clock-drawing scoring system predict dementia in elderly individuals with mild cognitive impairment? (2008)

The purpose of this study was to develop a clock-drawing scoring system better suited to detecting possible early markers of dementia in individuals with mild cognitive impairment (MCI). We modified the scoring system of Freedman et al. (1994), in which the major components are integrity of the circle, placement and size of the hands, and placement and sequence of the numbers. We rescored the clock-drawing test using a novel 18-point scoring system, which emphasizes hand elements-number of hands, direction indicated, and size differences. We retrospectively assessed 123 individuals (ages 58-88 years) selected from the Memory Clinic at the Jewish General Hospital in Montreal. These consisted of 21 normal elderly individuals (NORM group), 41 participants with mild cognitive impairment who did not develop dementia on follow-up visits (MCI-NP), 41 participants with mild cognitive impairment who became demented after a 48-month follow-up (MCI-D), and 20 participants diagnosed with Alzheimer's disease (AD). On the 18-point system, the MCI-NP and the MCI-D did not show any difference on overall total score (p = .166), However, using Pearson chi-squares to examine the within-categories effects comparing the mildly cognitively impaired groups (MCI-NP and MCI-D), there were three significant hand items that appear to be possible early markers of progression to dementia. The clock has two hands (p = .043), hour hand is towards correct number (p = .023), and size difference of the hands is respected (p = .004), all showed significant differences between progressors and nonprogressors. The 18-point clock-drawing scoring system may have advantages in better indicating MCI individuals more likely to progress to dementia.
Fluorine-18-labeled estrogens, progestins and corticosteroids for receptor-based imaging of breast tumors and target areas of the brain (1989)

Estrogens can be labeled with the positron-emitting radionuclide fluorine-18 (t$\\sb{1/2}$ = 110 min) by fluoride ion (n-Bu$\\sb4$N$\\sp{18}$F) displacement of a 16$\\beta$-trifluoromethanesulfonate (triflate) derivative of the corresponding estrone 3-triflate, and purification by HPLC. That sequence has been used to synthesize the 11$\\beta$-methoxy 1 and 11$\\beta$-ethyl 2 analogues of the breast tumor imaging agent, 16$\\alpha$-($\\sp{18}$F) fluoro-17$\\beta$-estradiol (FES). Tissue distribution studies of 1 and 2 in immature female rats show high selectivity for target tissue (T, uterus) vs non-target (NT, muscle and lung), with T/NT ratios being 43 and 17 at one hour after injection for 1 and 2, respectively. The parent estrogen FES has previously been shown to display an intermediate value for tissue selectivity.
Minimum Wheel-Rotation Paths for Differential-Drive Mobile Robots (2009)

The shortest paths for a mobile robot are a fundamental property of the mechanism, and may also be used as a family of primitives for motion planning in the presence of obstacles. This paper characterizes shortest paths for differential-drive mobile robots, with the goal of classifying solutions in the spirit of Dubins curves and Reeds—Shepp curves for car-like robots. To obtain a well-defined notion of shortest , the total amount of wheel-rotation is optimized. Using the Pontryagin Maximum Principle and other tools, we derive the set of optimal paths, and we give a representation of the extremals in the form of finite automata. It turns out that minimum time for the Reeds—Shepp car is equal to minimum wheel-rotation for the differential-drive, and minimum time curves for the convexified Reeds—Shepp car are exactly the same as minimum wheel-rotation paths for the differential-drive. It is currently unknown whether there is a simpler proof for this fact.

Data from Pacritinib Combined with Sirolimus and Low-Dose Tacrolimus for GVHD Prevention after Allogeneic Hematopoietic Cell Transplantation: Preclinical and Phase I Trial Results (2023)

&lt;div&gt;AbstractPurpose:&lt;p&gt;In this first-in-human, phase I, GVHD prevention trial (NCT02891603), we combine pacritinib (PAC), a JAK2 inhibitor, with sirolimus to concurrently reduce T-cell costimulation via mTOR and IL6 activity. We evaluate the safety of pacritinib when administered with sirolimus plus low-dose tacrolimus (PAC/SIR/TAC) after allogeneic hematopoietic cell transplantation.&lt;/p&gt;Patients and Methods:&lt;p&gt;The preclinical efficacy and immune modulation of PAC/SIR were investigated in xenogeneic GVHD. Our phase I trial followed a 3+3 dose-escalation design, including dose level 1 (pacritinib 100 mg daily), level 2 (pacritinib 100 mg twice daily), and level 3 (pacritinib 200 mg twice daily). The primary endpoint was to identify the lowest biologically active and safe dose of pacritinib with SIR/TAC (&lt;i&gt;n&lt;/i&gt; = 12). Acute GVHD was scored through day +100. Allografts included 8/8 HLA-matched related or unrelated donor peripheral blood stem cells.&lt;/p&gt;Results:&lt;p&gt;In mice, we show that dual JAK2/mTOR inhibition significantly reduces xenogeneic GVHD and increases peripheral regulatory T cell (Treg) potency as well as Treg induction from conventional CD4&lt;sup&gt;+&lt;/sup&gt; T cells. Pacritinib 100 mg twice a day was identified as the minimum biologically active and safe dose for further study. JAK2/mTOR inhibition suppresses pathogenic Th1 and Th17 cells, spares Tregs and antileukemia effector cells, and exhibits preliminary activity in preventing GVHD. PAC/SIR/TAC preserves donor cytomegalovirus (CMV) immunity and permits timely engraftment without cytopenias.&lt;/p&gt;Conclusions:&lt;p&gt;We demonstrate that PAC/SIR/TAC is safe and preliminarily limits acute GVHD, preserves donor CMV immunity, and permits timely engraftment. The efficacy of PAC/SIR/TAC will be tested in our ongoing phase II GVHD prevention trial.&lt;/p&gt;&lt;/div&gt;

Changes in differential threshold in patients with glaucoma during prolonged perimetry. (1983)

Patients with chronic open-angle glaucoma and others suspected of having glaucoma were subjected to continuous contrast threshold measurement by automatic and manual perimetric techniques. The results show that an increase of contrast threshold over time is a frequent finding in glaucoma patients and that this increment can be large, especially at points close to existing field defects. it is reproducible and independent of background illumination and can be demonstrated with both automatic and manual testing, but it is larger in the automatic than in the manual mode of testing. The results may have some important implications for visual field testing in glaucoma.

Metal Contacts on Physical Vapor Deposited Monolayer MoS2 (2013)

The understanding of the metal and transition metal dichalcogenide (TMD) interface is critical for future electronic device technologies based on this new class of two-dimensional semiconductors. Here, we investigate the initial growth of nanometer-thick Pd, Au, and Ag films on monolayer MoS2. Distinct growth morphologies are identified by atomic force microscopy: Pd forms a uniform contact, Au clusters into nanostructures, and Ag forms randomly distributed islands on MoS2. The formation of these different interfaces is elucidated by large-scale spin-polarized density functional theory calculations. Using Raman spectroscopy, we find that the interface homogeneity shows characteristic Raman shifts in E2g(1) and A1g modes. Interestingly, we show that insertion of graphene between metal and MoS2 can effectively decouple MoS2 from the perturbations imparted by metal contacts (e.g., strain), while maintaining an effective electronic coupling between metal contact and MoS2, suggesting that graphene can act as a conductive buffer layer in TMD electronics.
On feasibility of MPEG-4 for multimedia integration for e-commerce (2002)

First, we review the notion that Web-based business applications are being required to become increasingly sophisticated in the use of multimedia, although HTML-based Web browsers only offer limited multimedia capabilities. This leads us to briefly introduce MPEG-4, which offers improved capabilities for multimedia integration, and MPEG-7, which promises improved multimedia retrieval. Then, we discuss the general application area of e-commerce, that could potentially benefit from improved multimedia integration. Next, we discuss the key capabilities of MPEG-4 supported by the extended MPEG-4 browser that we employ to test multimedia integration for our e-commerce application. Next, we present e-travel, a fictitious e-commerce travel agent example application that we have developed to investigate the feasibility of MPEG-4 for multimedia integration. Finally, we discuss potential problems and prospects in migration of our example e-commerce application to a client/server framework.

A low-complexity, motion-robust, spatio-temporally adaptive video de-noiser with in-loop noise estimation (2008)

Noise in video influences the bit-rate and visual quality of video encoders and can significantly alter the effectiveness of video processing algorithms. Recent advances offer high quality de-noising at a fairly high computational complexity by increasing the spatio-temporal support and evaluating intelligent weights for combining these samples to remove noise while preserving the signal. The lower complexity methods, typically, either over-blur the video or introduce motion artifacts and temporal flicker. By reusing the motion vectors generated by a video encoder, a low incremental complexity de-noiser is proposed in this paper that is capable of achieving a high level of noise reduction and signal preservation with a reduced spatio-temporal support. In addition, the approach lends itself to dynamically estimating the noise variance used for controlling the level of filtering. The proposed approach performs on par with the spatial non-local means de-noising algorithm for stationary background sequences and can be improved for motion sequences with motion-compensated temporal filtering.
