A Skyrmion Racetrack Memory based Computing In-memory Architecture for Binary Neural Convolutional Network (2019)

A Skyrmion Racetrack Memory (SRM) based Computing In-Memory Architecture (SRM-CIM) was proposed in this paper. Both data and computing operation can be achieved in SRM-CIM. SRM-CIM is used to support convolutional computing in Binary Convolutional Neural Network (BCNN). Experimental results show that SRM-CIM achieves 98.7% and 82% energy reduction when compared with RRAM and SOT-MRAM based counterparts.
Texture-based fruit detection via images using the smooth patterns on the fruit (2016)

This paper describes a keypoint detection algorithm to accurately detect round fruits in high resolution imagery. The significant challenge associated with round fruits such as grapes and apples is that the surface is smooth and lacks definition and contrasting features, the contours of the fruit may be partially occluded, and the color of the fruit often blends with background foliage. We propose a fruit detection algorithm that utilizes the gradual variation of intensity and gradient orientation on the surface of the fruit. Candidate fruit locations, or “seed points” are tested for both monotonically decreasing intensity and gradient orientation profiles. Candidate fruit locations that pass the initial filter are classified using modified histogram of oriented gradients combined with a pairwise intensity comparison texture descriptor and random forest classifier. We analyse the performance of the fruit detection algorithm on image datasets of grapes and apples using human labeled images as ground truth. Our method to detect candidate fruit locations is scale invariant, robust to partial occlusions and more accurate than existing methods. We achieve overall F1 accuracy score of 0.82 for grapes and 0.80 for apples. We demonstrate our method is more accurate than existing methods.
First Selective CYP11B1 Inhibitors for the Treatment of Cortisol-Dependent Diseases (2010)

Outgoing from an etomidate-based design concept, we succeeded in the development of a series of highly active and selective inhibitors of CYP11B1, the key enzyme of cortisol biosynthesis, as potential drugs for the treatment of Cushing's syndrome and related diseases. Thus, compound 33 (IC50 = 152 nM) is the first CYP11B1 inhibitor showing a rather good selectivity toward the most important steroidogenic CYP enzymes aldosterone synthase (CYP11B2), the androgen-forming CYP17, and aromatase (estrogen synthase, CYP19).
Development of dietary soluble fibres by enzymatic synthesis and assessment of their digestibility in <i>in vitro</i>, animal and randomised clinical trial models (2017)

The aim was to develop novel fibres by enzymatic synthesis, to determine their total dietary fibre by AOAC method 2009.01 and to estimate their potential digestibility and assess their digestibility in vivo using glycaemic and insulinaemic responses as markers in mice and randomised clinical trial models. We found that fibre candidates to which α-(1,2) branching was added were resistant to digestion in the mouse model, depending on the amount of branching. These results show that in vivo models are needed to reliably assess the digestibility of α-glycosidic-linked oligomeric dietary fibre candidates, possibly due to absence of brush border α-glucosidase activity in the current in vitro assessment. α-(1,3)-linked and α-(1,6)-linked glucose oligomers were completely digested in humans and mice. In conclusion, it is possible to develop dietary soluble fibres by enzymatic synthesis. Adding α-(1,2) branching increases their resistance to digestion in vivo and can thus improve their suitability as potential fibre candidates.

TIRE POWER LOSS: THE EFFECT OF HEAT CONDUCTION THROUGH THE WHEEL (1982)

Previously reported analysis has indicated and experiments have confirmed that the thermal state of a tire and the factors which affect it have a large influence on tire power loss. An experimental program was conducted to determine the potential for power loss reduction through reductions in one of these factors--the rate of heat flux from tire to wheel. The specific approaches studied ranged from applying thermally insulating coatings on selected wheel surfaces to using inner tubes. A maximum power loss reduction of 7.4% was achieved by applying a 1 to 2 mm thick layer of body undercoating to the externally exposed surfaces of a styled aluminum wheel.
Large Displacement Optical Flow from Nearest Neighbor Fields (2013)

We present an optical flow algorithm for large displacement motions. Most existing optical flow methods use the standard coarse-to-fine framework to deal with large displacement motions which has intrinsic limitations. Instead, we formulate the motion estimation problem as a motion segmentation problem. We use approximate nearest neighbor fields to compute an initial motion field and use a robust algorithm to compute a set of similarity transformations as the motion candidates for segmentation. To account for deviations from similarity transformations, we add local deformations in the segmentation process. We also observe that small objects can be better recovered using translations as the motion candidates. We fuse the motion results obtained under similarity transformations and under translations together before a final refinement. Experimental validation shows that our method can successfully handle large displacement motions. Although we particularly focus on large displacement motions in this work, we make no sacrifice in terms of overall performance. In particular, our method ranks at the top of the Middlebury benchmark.
Average Physical Enhancement by Nanomaterials under X-ray Irradiation (2014)

We for the first time used highly water-soluble silica-covered gold nanoparticles (AuNP@SiO2) in water to successfully isolate average physical enhancement from other enhancements such as nanoscale physical enhancement, chemical enhancement, and antienhancement and obtained the highest enhancement slope of 1.03 per weight percent (wp–1) and the highest experimental enhancement factor of 4.5-fold (εexpt = 4.5 and εexpt= 0 for no enhancement) at 7.5 wp of gold in water. The slope and εexpt agree with the theoretically predicted values obtained from simulation of enhancement of X-rays by gold nanoparticles in water, and the experimental enhancement coefficient (γ = εexpt/εtheo, 0 ≤ γ ≤ 1) is approximately 0.90. The enhancement dependency on X-ray energy, silica layer thickness, and sample thickness were studied experimentally and theoretically. The results presented here elucidate the mechanism of the average physical enhancement by nanomaterials under X-ray irradiation.
Potentiation of regulatory T cell stability and function via a neuropilin-1:semaphorin-4a axis (P1057) (2013)

Abstract Regulatory T cells represent a critical immunoregulatory component of the immune system. The signals that maintain Treg stability and potentiate their function remain obscure. Here we show that the immune cell surface ligand semaphorin-4a on conventional murine and human T cells and dendritic cells interacts with the Treg-restricted receptor neuropilin-1 to potentiate Treg function and enhance survival. Mice with a Treg-restricted deletion of Nrp1 exhibit extremely limited tumor-induced tolerance, and thus substantial resistance to certain tumors, yet do not develop any autoimmune or inflammatory manifestations. Sema4a or Nrp1 blockade also had therapeutic efficacy against pre-existing tumors. In addition, Nrp1-deficient Treg cells fail to suppress inflammatory colitis. Upon Sema4a ligation, Nrp1 was recruited to the immunological synapse and repressed Akt activity via PTEN, which facilitated Foxo nuclear translocation. This induced a transcriptional program that promoted Treg stability, survival and function while repressing the induction of lineage-specific transcription factors. Thus, Nrp1 ligation enforces Treg stability and function in highly inflammatory sites but is dispensable for the maintenance of immune homeostasis, highlighting Nrp1 as a potential immunotherapeutic target in cancer.
Holographic recordings with high beam ratios on improved Bayfol<sup>®</sup>HX photopolymer (2013)

Bayfol<sup>®</sup> HX film is a new class of recording materials for volume holography. It was commercialized in 2010 and is offering the advantages for full-color recording and moisture resistance without any chemical or thermal processing, combined with low shrinkage and detuning. These photopolymers are based on the two-chemistry concept in which the writing chemistry is dissolved in a preformed polymeric network. This network provides the necessary mechanical stability to the material prior to recording. In addition to the well-known security and imaging applications, Bayfol<sup>®</sup> HX film also offers a new opportunity for the manufacturing of volume Holographic Optical Elements (vHOEs) in new optical and optoelectronic applications. For the implementation of holographic recording layouts and associated exposure schedules for these HOEs detailed understanding of the photopolymer material properties and the knowledge how to achieve the optical requirements of dedicated holographic applications are necessary. In this paper we extend the application of our simulation method for the writing mechanism for the Bayfol<sup>®</sup> HX photopolymer film. Different photopolymer product variations, including development of photopolymer grades with improved bleaching properties and increased dynamical range, which enable simultaneous multi-color recording, while maintaining a high diffraction efficiency of the recorded holograms are covered. The model is investigated experimentally by recording and evaluation of specifically designed directional diffuser vHOEs as they would be used e.g. for light shaping or light management purposes. One important observation is the capability of Bayfol<sup>®</sup> HX film type photopolymers to form highly efficient diffraction gratings even at very high intensity ratios of the reference beam versus the object beam.
Antibody response to a Babesia bigemina rhoptry-associated protein 1 surface-exposed and neutralization-sensitive epitope in immune cattle (1994)

Protective immunity against Babesia bigemina is hypothesized to involve antibodies directed against merozoite surface-exposed epitopes. Levels of antibody against a rhoptry-associated protein 1 (RAP-1) B-lymphocyte epitope, defined by surface-reactive and inhibitory monoclonal antibodies, in immune cattle sera were determined. All cattle produced antibodies to the epitope; however, there was limited correlation between immune protection induced by infection or RAP-1 immunization and the level of antibody to the neutralization-sensitive B-lymphocyte epitope examined.
Structure Development Study of Pb (Zr, Ti)O <sub>3</sub> Thin Films by an Optical Method (1994)

Lead zirconate titanates (Pb (Zr x Ti 1–x )O 3 or PZT) are well‐known materials with useful ferroelectric properties for nonvolatile memory applications. The device applications usually require processes which form the ferroelectric perovskite phase at low temperatures. Understanding the various aspects of structure development of PZT films is the key to develop low‐temperature processes. An effective, versatile, and nondestructive optical method was developed for the study of the structure development in PZT films. Also, models for the structure development were proposed and were verified by this optical method. Using this method, the characteristic temperatures at which both pyrochlore phase and perovskite phase are initiated and completed were identified. The pyrochloreperovskite transformation was initiated at lower temperature and completed faster for the films on the titanium‐rich side than those on the zirconium‐rich side. In addition, the volume fractions of the perovskite phase were obtained as a function of annealing temperature by this optical method.
Automatic cardiac flow quantification on 3D volume color Doppler data (2011)

Valvular heart diseases are recognized as a significant cause of morbidity and mortality. Accurate quantification of cardiac flow volumes in patients is essential in evaluation of the progression of the disease and in determination of clinical options. Recent advances in the real-time 3D full volume echocardiography have enabled high frame rate acquisition of volumetric color Doppler flow images. In this paper, we propose a fully automated method to quantify the cardiac flow using instantaneous 3D+t ultrasound data. The anatomical information such as mitral annulus and left ventricle outflow tract (LVOT) are detected and tracked automatically accounting for the heart motion. Furthermore, the proposed method automatically detects and tracks the endocardial boundary of the left ventricle (LV) and computes the instantaneous change in LV volume. This information is used to overcome inherent limitation of the color Doppler velocity ambiguity such that de-aliasing parameters are computed and used to correct flow computations. Preliminary results with clinical data presented here agree well with accepted clinical measurements in a quantitative manner. The proposed method is efficient and achieves high speed performance of 0.2 second per volume of ultrasound data.

Core Mode Scramblers for ML-detection based Multi-Core Fibers Transmission (2017)

We investigate the performance of Heterogeneous Multi-Core Fiber communication systems. We define the Core Dependent Loss (CDL) as a result of both crosstalk and misalignment. We propose random core scrambling to mitigate the CDL and so enhance the system performance.
Development of a New Borax-Based Formulation for the Removal of Pyrite Scales (2020)

In the oil and gas industry, pyrite forms one of the most hardened scales in reservoirs, which hinders the flow of fluids. Consequently, this leads to blockage of the downhole tubular, formation damage, and complete shutdown of production and operational processes. Herein, a new green formulation based on borax (K<sub>2</sub>B<sub>4</sub>O<sub>7</sub>) is proposed for pyrite scale removal. The temperature effect, disk rotational speed, and borax concentration have been investigated using a rotating disk apparatus. Also, XPS and SEM-EDX analyses were conducted on the pyrite disk surface before and after the treatment with the green formulation. The new formulation showed the potential ability to dissolve pyrite without generating the toxic hydrogen sulfide (H<sub>2</sub>S). The dissolution rate of the scale in the new formulation is increased by 16% compared to that in a previous green formulation composed of 20 wt %DTPA+9 wt % K<sub>2</sub>CO<sub>3</sub>. Molecular modeling technique using DFT was used to study the solvation energies of Fe<sup>2+</sup> and Fe<sup>3+</sup>. The latter had a higher solvation energy than the former, which confirmed that upon using the borax-based formulation to oxidize Fe<sup>2+</sup> to Fe<sup>3+</sup>. It will aid the dissolution of pyrite scales. The new formulation achieved a corrosion rate that is 25 times lower than that of 15 wt % HCl, which is commercially used in treating scales. Finally, the proposed new formulation does not require the use of corrosion inhibitors; hence, it is expected to result in a more economical scale treatment method.

On the feasibility of multi-site web search engines (2009)

Web search engines are often implemented as centralized systems. Designing and implementing a Web search engine in a distributed environment is a challenging engineering task that encompasses many interesting research questions. However, distributing a search engine across multiple sites has several advantages, such as utilizing less compute resources and exploiting data locality. In this paper we investigate the cost-effectiveness of building a distributed Web search engine. We propose a model for assessing the total cost of a distributed Web search engine that includes the computational costs and the communication cost among all distributed sites. We then present a query-processing algorithm that maximizes the amount of queries answered locally, without sacrificing the quality of the results compared to a centralized search engine. We simulate the algorithm on real document collections and query workloads to measure the actual parameters needed for our cost model, and we show that a distributed search engine can be competitive compared to a centralized architecture with respect to real cost.
Assessment of Remaining Lubricant Life (1986)

An investigation was conducted in order to develop a remaining lubricant life assessment test (RLLAT) for MIL-L-7808 lubricating oils. The RLLAT would enable the Air Force to reduce material and labor costs by eliminating scheduled oil changes. In Task 1 analytical procedures capable of performing remaining lubricant life (RLL) assessments of MIL-L-7808 lubricating oils were identified and evaluated. Of the numerous analytical procedures identified in Task 1, procedures based on cyclic voltammetry, differential scanning calorimetry (DSC), and chemical stressing were determined to be the best candidates for development into a RLLAT. In Task 2, a RLLAT was developed from the reductive-cyclic voltammetric (RCV) technique and a microcomputer based data acquisition system. The RLLAT based on the RCV technique and data acquisition system (RLLAT-RCV) was rapid (total analysis time less than 30 seconds), inexpensive (less than $3,00), and base-level in operation and RLL assessments. The development of RLLAT from the DSC techniques were limited by the high instrumental costs (greater than $20,000). The development of RLLAT from the chemical stressing techniques were limited by the toxicity and instability of the required reagents and the difficult interpretation of the techniques' results. In Task 3, the applicability of the RLLAT-RCV to different types of lubricating was demonstrated. The results in Task 3 also showed that the RLLAT-RCV could be used to detect engines experiencing severe wear in addition to being used to eliminate scheduled oil changes.
Structural and electronic modification of photovoltaic SnS by alloying (2014)

Emergence of a terawatt scalable photovoltaic (PV) thin film technology is currently impeded by the limited supply of relatively rare elements like In or Te, which has spurred active research in recent years on earth-abundant PV materials. Instead of searching for alternative PV materials, we approach the problem here by structural modification through alloying of a known PV material, namely, tin sulfide. Although SnS is a strong visible light absorber that is naturally p-doped, its indirect band gap reduces the open circuit voltage of SnS-based solar cells. The anisotropic crystal structure results in undesirable anisotropic transport properties. Based on the observation that the isoelectronic sulfides MgS, CaS, and SrS assume the rock-salt structure, we use ab initio calculations to explore the structure and electronic properties of metastable Sn1−x(II)xS (II = Mg, Ca, Sr) alloys, finding that the isotropic rock-salt phase is stabilized above x = 0.2–0.3, and predicting direct band gaps in the range of interest for PV applications, i.e., 0.6–1.5 eV for Ca and Sr alloying. We subsequently synthesized such Sn1−x(Ca)xS films by pulsed laser deposition, confirmed the cubic rock-salt structure, and observed optical band gaps between 1.1 and 1.3 eV. These results highlight the potential of structural modification by alloying as a route to widen the otherwise limited materials base for promising earth-abundant materials.
Determination of Alcohol Concentration in Aqueous Solutions and Food Analysis using Reflection Terahertz Time-Domain Spectroscopy (2007)

We use self-referencing reflection THz spectroscopy to measure the alcohol- and sugar concentration with high precision in small volumes of aqueous solutions, independent of carbonation and the contents of yeast or other small organic particles.
Intravenous Transplants of Human Adipose-Derived Stem Cell Protect the Brain from Traumatic Brain Injury-Induced Neurodegeneration and Motor and Cognitive Impairments: Cell Graft Biodistribution and Soluble Factors in Young and Aged Rats (2013)

Traumatic brain injury (TBI) survivors exhibit motor and cognitive symptoms from the primary injury that can become aggravated over time because of secondary cell death. In the present in vivo study, we examined the beneficial effects of human adipose-derived stem cells (hADSCs) in a controlled cortical impact model of mild TBI using young (6 months) and aged (20 months) F344 rats. Animals were transplanted intravenously with 4 × 10(6) hADSCs (Tx), conditioned media (CM), or vehicle (unconditioned media) at 3 h after TBI. Significant amelioration of motor and cognitive functions was revealed in young, but not aged, Tx and CM groups. Fluorescent imaging in vivo and ex vivo revealed 1,1' dioactadecyl-3-3-3',3'-tetramethylindotricarbocyanine iodide-labeled hADSCs in peripheral organs and brain after TBI. Spatiotemporal deposition of hADSCs differed between young and aged rats, most notably reduced migration to the aged spleen. Significant reduction in cortical damage and hippocampal cell loss was observed in both Tx and CM groups in young rats, whereas less neuroprotection was detected in the aged rats and mainly in the Tx group but not the CM group. CM harvested from hADSCs with silencing of either NEAT1 (nuclear enriched abundant transcript 1) or MALAT1 (metastasis associated lung adenocarcinoma transcript 1), long noncoding RNAs (lncRNAs) known to play a role in gene expression, lost the efficacy in our model. Altogether, hADSCs are promising therapeutic cells for TBI, and lncRNAs in the secretome is an important mechanism of cell therapy. Furthermore, hADSCs showed reduced efficacy in aged rats, which may in part result from decreased homing of the cells to the spleen.
