Social search and discovery using a unified approach (2009)

This research explores new ways to augment the search and discovery of relations between Web 2.0 entities using multiple types and sources of social information. Our goal is to allow the search for all object types such as documents, persons and tags, while retrieving related objects of all types. We implemented a social-search engine using a unified approach, where the search space is expanded to represent heterogeneous information objects that are interrelated by several relation types. Our solution is based on multifaceted search, which provides an efficient update mechanism for relations between objects, as well as efficient search over the heterogeneous data. We describe a social search engine positioned within a large enterprise, applied over social data gathered from several Web 2.0 applications. We conducted a large user study with over 600 people to evaluate the contribution of social data for search. Our results demonstrate the high precision of social search results and confirm the strong relationship of users and tags to the topics retrieved.
SHOCK ISOLATION THROUGH PASSIVE ENERGY PUMPING CAUSED BY NONSMOOTH NONLINEARITIES (2005)

We investigate shock isolation designs based on nonlinear energy pumping caused by nonsmooth stiffness elements. In particular, we numerically study the shock isolation properties of a primary linear system of two coupled nonconservative oscillators with weakly coupled attachments possessing clearance nonlinearities. Under shock excitation the nonlinear attachments (termed nonlinear energy sinks — NESs) can be designed to absorb a significant portion of the input energy, thus enhancing the shock isolation performance of the primary system. In contrast to the classical linear vibration absorber whose operation is restricted to narrowband frequency ranges, the NESs are capable of efficiently absorbing energies caused by transient broadband disturbances, a feature that facilitates their implementation in practical applications. Moreover, the nonsmooth nonlinearities considered in this work are easily implementable since they are realized by means of linear stiffness elements.
Solid‐Phase Epitaxial Growth of A‐Site‐Ordered Perovskite Sr<sub>4−<i>x</i></sub>Er<i><sub>x</sub></i>Co<sub>4</sub>O<sub>12−<i>δ</i></sub>: A Room Temperature Ferrimagnetic p‐Type Semiconductor (2015)

The oxygen‐deficient Sr 4− x Er x Co 4 O 12− δ (SECO), one of the ordered perovskite oxides, is a room‐temperature (RT) ferrimagnetic semiconductor that arises from the A‐site‐ordered structure. Development of such a material can lead to the realization of spintronic heterojunction devices; however, to this point there have been difficulties in achieving the A‐site‐ordered structure in SECO thin films. Here, single‐crystalline film growth of SECO with perfectly aligned A‐site‐ordered structure on (LaAlO 3 ) 0.3 (Sr 2 TaAlO 6 ) 0.7 substrates by solid‐phase epitaxy (SPE) method is demonstrated. The brownmillerite‐type, A‐site‐disordered structure of the as‐grown epitaxial film clearly changes into well‐aligned A‐site‐ordered structure after heat treatment at 1050 °C in air; the aligned ordered structure in the film is clearly visualized at atomic level. This ordering induces ferrimagnetism with Curie temperature ( T c ) ≈310 K and it is found that the SECO film with p‐type semiconductivity exhibits anomalous Hall effect at the temperature up to 300 K, which is suitable for the test bench to demonstrate advanced spintronic heterojunction devices, operating at RT. The present SPE method is expected to serve as a powerful technique for the fabrication of thin films and exploration of potential characteristics of A‐site‐ordered perovskite oxides.

From Selection to Instruction and Back: Competing Conformational Selection and Induced Fit Pathways in Abiotic Hosts (2021)

Two limiting cases of molecular recognition, induced fit (IF) and conformational selection (CS), play a central role in allosteric regulation of natural systems. The IF paradigm states that a substrate "instructs" the host to change its shape after complexation, while CS asserts that a guest "selects" the optimal fit from an ensemble of preexisting host conformations. With no studies that quantitatively address the interplay of two limiting pathways in abiotic systems, we herein and for the first time describe the way by which twisted capsule M-1, encompassing two conformers M-1(+) and M-1(-), trap CX<sub>4</sub> (X=Cl, Br) to give CX<sub>4</sub> ⊂M-1(+) and CX<sub>4</sub> ⊂M-1(-), with all four states being in thermal equilibrium. With the assistance of 2D EXSY, we found that CBr<sub>4</sub> would, at its lower concentrations, bind M-1 via a M-1(+)→M-1(-)→CBr<sub>4</sub> ⊂M-1(-) pathway corresponding to conformational selection. For M-1 complexing CCl<sub>4</sub> though, data from 2D EXSY measurements and 1D NMR line-shape analysis suggested that lower CCl<sub>4</sub> concentrations would favor CS while the IF pathway prevailed at higher proportions of the guest. Since CS and IF are not mutually exclusive, we reason that our work sets the stage for characterizing the dynamics of a wide range of already existing hosts to broaden our fundamental understanding of their action. The objective is to master the way in which encapsulation takes place for designing novel and allosteric sequestering agents, catalysts and chemosensors akin to those found in nature.
Fine-tuning convolutional deep features for MRI based brain tumor classification (2017)

Prediction of survival time from brain tumor magnetic resonance images (MRI) is not commonly performed and would ordinarily be a time consuming process. However, current cross-sectional imaging techniques, particularly MRI, can be used to generate many features that may provide information on the patient’s prognosis, including survival. This information can potentially be used to identify individuals who would benefit from more aggressive therapy. Rather than using pre-defined and hand-engineered features as with current radiomics methods, we investigated the use of deep features extracted from pre-trained convolutional neural networks (CNNs) in predicting survival time. We also provide evidence for the power of domain specific fine-tuning in improving the performance of a pre-trained CNN’s, even though our data set is small. We fine-tuned a CNN initially trained on a large natural image recognition dataset (Imagenet ILSVRC) and transferred the learned feature representations to the survival time prediction task, obtaining over 81% accuracy in a leave one out cross validation.

Analtic Findings in the Photographic Characterization of Crystalline Silicon Solar Cells using Electroluminescence (2006)

The electroluminescence (EL) intensity from Si cells under the forward bias was found to have one to one quantitative agreement with the minority carrier diffusion length. Based on the diffusion equation, the EL intensity was analyzed relating to the cell performance. Diffusion length difference between grains could be elucidated in addition to the clear imaging of grain boundaries. When the effective diffusion length was influenced by the rear surface recombination velocity (i.e., the bulk diffusion length was longer than the active layer thickness), the EL intensity represented the quality of rear surface passivation processes. Ideality factor n could be deduced by measuring the EL intensity as a function of the forward injection current

Chalcogen-Nitrogen Bond: Insights into a Key Chemical Motif (2021)

Chalcogen-nitrogen chemistry deals with systems in which sulfur, selenium, or tellurium is linked to a nitrogen nucleus. This chemical motif is a key component of different functional structures, ranging from inorganic materials and polymers, to rationally designed catalysts, to bioinspired molecules and enzymes. The formation of a selenium–nitrogen bond, typically occurring upon condensation of an amine and the unstable selenenic acid, often leading to intramolecular cyclizations, and its disruption, mainly promoted by thiols, are rather common events in organic Se-catalyzed processes. In this work, focusing on examples taken from selenium organic chemistry and biochemistry, the selenium–nitrogen bond is described, and its strength and reactivity are quantified using accurate computational methods applied to model molecular systems. The intermediate strength of the Se–N bond, which can be tuned to necessity, gives rise to significant trends when comparing it to the stronger S– and weaker Te–N bonds, reaffirming also in this context the peculiar and valuable role of selenium in chemistry and life.
Is Genetic Testing for Heart Disease Right for Me? (2019)

Is Genetic Testing for Heart Disease Right for Me?Heart disease is a leading cause of death worldwide and often runs in families.Certain heart conditions, such as those in the Figure, are caused by a single harmful DNA variation (or mutation) while others, such as heart attack and high blood pressure, are usually caused by the combined effect of many smaller-impact DNA variations.Tests for the latter are emerging but are not yet reliable enough for common use.Tests for the former can be ordered by cardiologists and genetic counselors.These tests can help patients and their families know who is at risk for disease.

Abstract 2805: DFMO and 5-azacytidine increase M1 macrophages in the tumor microenvironment of an ovarian cancer mouse model (2019)

Although ovarian cancer has a low incidence rate encompassing roughly 1% of all new cancers, it remains the most deadly gynecologic malignancy. Our lab has designed a novel combination therapy which combines a DNA methyl transferase inhibitor (DNMTi) and ornithine decarboxylase inhibitor that together, alter the tumor microenvironment to inhibit ovarian tumor growth. Previous work has demonstrated that the DNMTi 5-Azacytidine (AZA) activates type I interferon signaling (Li, 2014, Chiappinelli, 2015) to increase IFNγ+ T cells and NK cells and reduce the percentage of macrophages and myeloid derived suppressor cells (MDSCs) in the tumor microenvironment (Stone, 2017). To improve the efficacy of epigenetic therapy, we hypothesized that the addition of α-difluoromethylornithine (DFMO), an ornithine decarboxylase inhibitor may decrease activity of MDSCs through inhibition of arginase. Immunocompetent C57Bl/6 mice were injected with syngeneic mouse ovarian surface epithelial (MOSE) tumor cells (ID8-VEGF-Defensin) and subsequently treated with AZA, DFMO, or combination AZA+DFMO. After several weeks, mice developed hemorrhagic ascites that was drained, processed and stained for cell-surface markers and analyzed by flow cytometry to identify T cells, NK cells, and macrophages. We found that in vivo AZA, DFMO, and AZA+DFMO significantly increased survival in mice, decreased tumor burden, and caused recruitment of activated (IFNγ+) CD4+ T cells, CD8+ T cells, and NK Cells compared to vehicle. The combination therapy had a striking increase in survival when compared to single agent treatment; however, the difference in recruited lymphocytes was less striking. Instead, combination therapy led to the most dramatic decrease in immunosuppressive cells such as M2 polarized macrophages and increase in tumor-killing M1 macrophages. Using a CSF1R blocking antibody, we found that depleting macrophages in this model reduced the efficacy of AZA+DFMO treatment, and resulted in fewer M1 macrophages in the tumor microenvironment. We thus conclude that our novel combination therapy modifies macrophage polarization in the tumor microenvironment, recruiting M1 macrophages and prolonging survival. We hypothesize that this treatment regimen could have a widespread impact on macrophage-rich tumors in general, and plan to test this hypothesis in additional tumor models.Citation Format: Meghan Travers, Stephen Brown, Matthew Dunworth, Cassandra Holbert, Robert Casero, Cynthia Zahnow.

Investigation of Cu-Deficient Copper Gallium Selenide Thin Film as a Photocathode for Photoelectrochemical Water Splitting (2012)

Polycrystalline thin films of CuGaSe2-related Cu-deficient materials were prepared by vacuum co-evaporation. The composition was adjusted in order to prepare copper gallium selenide, abbreviated as CGSe, with an optimal band gap and valence band maximum position for photoelectrochemical water splitting. The effect of the Ga/Cu ratio on the photoelectrochemical properties of CGSe was also studied. With increasing Ga/Cu ratio, the band gap of CGSe became larger, and the valence band maximum position became deeper against the vacuum level. However, an analysis of the photocurrent and onset potential indicated that the Ga/Cu ratio should be less than 3.5 for optimal performance. A Pt-deposited CGSe electrode with a Ga/Cu ratio of 3 showed an onset potential of about 1.1 V vs RHE and an energy conversion efficiency of 0.35% under AM 1.5G light illumination in a 0.1 M Na2SO4 solution with pH 9.5.

Experimental Fragility Analysis of Suspension Ceiling Systems (2015)

The seismic response of suspended ceiling systems that were shaken at the University at Buffalo; University of Nevada, Reno; and E‐Defense facilities is critically assessed in this paper. After presenting a brief description of each experiment, the most repetitive damage observations in all experiments are discussed. Fragility curves are developed for ceiling perimeter connectors, supporting elements, and overall performance of ceiling systems by using 346 combinations of ceiling configurations and shake intensities. The key findings of these curves are the insufficient support of the 7/8‐in. wall angles, unconservative code design capacity of connections for supporting elements, and early damage of ceiling systems because of ceiling‐piping interaction. Acceleration amplification factors of ceiling systems with respect to suspending floor are computed. The amplification factors prescribed by the code were found to be unconservative due to the pounding of panels to the ceiling grids and deck vibration in a vertical direction.
Cooperative relaying in a SWIPT network:Asymptotic analysis using\n extreme value theory for non-identically distributed RVs (2020)

This paper derives the distribution of the maximum end-to-end (e2e) signal to\nnoise ratio (SNR) in an opportunistic relay selection based cooperative\nrelaying (CR) network having large number of non-identical relay links between\nthe source and destination node. The source node is assumed to be simultaneous\nwireless information and power transfer (SWIPT) enabled and the relays are\ncapable of both time splitting (TS) and power splitting (PS) based energy\nharvesting (EH). Contrary to the majority of literature in communication, which\nuses extreme value theory (EVT) to derive the statistics of extremes of\nsequences of independent and identically distributed (i.i.d.) random variables\n(RVs), we demonstrate how tools from EVT can be used to derive the asymptotic\nstatistics of sequences of independent and non-identically distributed\n(i.n.i.d.) normalised SNR RVs and hence characterise the distribution of the\nmaximum e2e SNR RV. Using these results we derive the expressions for ergodic\nand outage capacities at the destination node. Finally, we present the utility\nof the asymptotic results for deciding the optimum TS and PS factors of the\nhybrid EH relays that (i) minimise outage probability and (ii) maximise ergodic\ncapacity at the destination. Furthermore, we demonstrate how stochastic\nordering results can be utilised for simplifying these optimisation problems.\n
New hexadentate ligands composed of 1-hydroxy-2(1H )-pyrimidinone, α,ω-diamine and 1,1,1-tris(carboxyethoxymethyl)ethane or tri(carboxybutyl)isocyanurate. Synthesis and characterization of their iron(III) complexes (1998)

The successive coupling of 1-benzyloxy-2(1H)-pyrimidinone with α,ω-diamines, 1,1,1-tris(carboxyethoxymethyl)ethane or tri(carboxybutyl)isocyanurate, and final removal of the benzyl protecting group afforded new hexadentate ligands (TEPOHn or TCPOH). The UV/VIS spectroscopic analysis in aqueous solution indicated 1∶1 stoichiometric complexation of the hexadentate ligand with iron(III). The relative stability constants of iron(III) complexes of the hexadentate ligands were estimated to be log K 24.4–26.3 by the competitive reaction with EDTA, suggesting that the stability was affected by the methylene chain length. The standard redox potential E1/2 of Fe(TEPO2) was measured to be –493 mV at apparent pH 8.0 in 50% aqueous DMF solution. This value was approximately 300 mV higher than that of the iron(III) complex of natural desferrioxamine B (DFB). Further, all synthetic hexadentate ligands effectively removed 3–6 times as much iron(III) from human transferrin as DFB even though the ratio of the synthetic ligand to transferrin was one-fifth that of DFB.

New Aspects of Endochondral Ossification in the Chick: Chondrocyte Apoptosis, Bone Formation by Former Chondrocytes, and Acid Phosphatase Activity in the Endochondral Bone Matrix (1997)

A detailed histological study of the growth plates from 9- to 20-day-old embryonic chick long bones was carried out with the aim of clarifying the long-debated question of the fate of the hypertrophic chondrocytes. Since resorption in chick bones does not occur synchronously across the plate as it does in mammals, specialized regions develop and the fate of the chondrocyte depends on its location within the growth plate. Where resorption took place, as at the sites of primary vascular invasion or at the main cartilage/marrow interface, chondrocytes underwent apoptosis before the lacunae were opened. In addition, spontaneous apoptosis of chondrocytes occurred at apparently random sites throughout all stages of chondrocyte differentiation. In older chick bones, a thick layer of endochondral bone matrix covered the cartilage edge. This consisted of type I collagen and the typical noncollagenous bone proteins but, in addition, contained tartrate-resistant acid phosphatase in the mineralized matrix. Where such matrix temporarily protected the subjacent cartilage from resorption, chondrocytes differentiated to bone-forming cells and deposited bone matrix inside their lacunae. At sites of first endochondral bone formation, some chondrocytes underwent an asymmetric cell division resulting in one daughter cell which underwent apoptosis, while the other cell remained viable and re-entered the cell cycle. This provided further support for the notion that chondrocytes as well as marrow stromal cells give rise to endochondral osteoblasts.
