From Sphingosine Kinase to Dihydroceramide Desaturase: A Structure–Activity Relationship (SAR) Study of the Enzyme Inhibitory and Anticancer Activity of 4-((4-(4-Chlorophenyl)thiazol-2-yl)amino)phenol (SKI-II) (2016)

The sphingosine kinase (SK) inhibitor, SKI-II, has been employed extensively in biological investigations of the role of SK1 and SK2 in disease and has demonstrated impressive anticancer activity in vitro and in vivo. However, interpretations of results using this pharmacological agent are complicated by several factors: poor SK1/2 selectivity, additional activity as an inducer of SK1-degradation, and off-target effects, including its recently identified capacity to inhibit dihydroceramide desaturase-1 (Des1). In this study, we have delineated the structure-activity relationship (SAR) for these different targets and correlated them to that required for anticancer activity and determined that Des1 inhibition is primarily responsible for the antiproliferative effects of SKI-II and its analogues. In the course of these efforts, a series of novel SK1, SK2, and Des1 inhibitors have been generated, including compounds with significantly greater anticancer activity.
Scene change detection algorithms for content-based video indexing and retrieval (2001)

There is an urgent need to extract key information from video automatically for the purposes of indexing, fast retrieval, and scene analysis. To support this vision, reliable scene change detection algorithms must be developed. Several algorithms have been proposed for both sudden and gradual scene change detection in uncompressed and compressed video. In this paper some common algorithms that have been proposed for scene change detection are reviewed. A novel algorithm for sudden scene change detection for MPEG-2 compressed video is then presented. This uses the number of interpolated macroblocks in B-frames to identify the sudden scene changes. A gradual scene change detection algorithm based on statistical features is also presented.

Development of a building integrated photovoltaic/thermal solar energy cogeneration system (2008)

Using renewable energy sources for onsite cogeneration from structural building elements is a relatively new concept and is gaining considerable interest. In this study the design, development, manufacturing and testing of a novel building integrated photovoltaic/thermal (BIPVT) solar energy cogeneration system is discussed.&#13;\nAdhesives (ADH), resistance seam welding (RSW) and autoclaving (ATC) were identified as the most appropriate for fabricating BIPVT roofing panels. Of these manufacturing methods ADH was found to be most suitable for low volume production systems due to its low capital cost. A prototype panel, fabricated using ADH methods, exhibited good thermal performance. It was also shown that BIPVT performance could be theoretically predicted using a onedimensional heat transfer model and showed excellent agreement with experimental data. The model was used to suggest further design improvements. Finally, a transient simulation of the BIPVT was performed in TRNSYS and is used to illustrate the benefits of the system.
Bayesian Co-Training (2007)

Co-training (or more generally, co-regularization) has been a popular algorithm for semi-supervised learning in data with two feature representations (or views), but the fundamental assumptions underlying this type of models are still unclear. In this paper we propose a Bayesian undirected graphical model for co-training, or more generally for semi-supervised multi-view learning. This makes explicit the previously unstated assumptions of a large class of co-training type algorithms, and also clarifies the circumstances under which these assumptions fail. Building upon new insights from this model, we propose an improved method for co-training, which is a novel co-training kernel for Gaussian process classifiers. The resulting approach is convex and avoids local-maxima problems, and it can also automatically estimate how much each view should be trusted to accommodate noisy or unreliable views. The Bayesian co-training approach can also elegantly handle data samples with missing views, that is, some of the views are not available for some data points at learning time. This is further extended to an active sensing framework, in which the missing (sample, view) pairs are actively acquired to improve learning performance. The strength of active sensing model is that one actively sensed (sample, view) pair would improve the joint multi-view classification on all the samples. Experiments on toy data and several real world data sets illustrate the benefits of this approach.
An ELECTRE III Based CBR Approach to Combinatorial Portfolio Selection (2019)

Abstract Investors generally learn from historical data and use it to improve future investment decisions. However, existing portfolio selection research rarely considers such a concept. This paper proposes a novel approach to the combinatorial portfolio selection problem. Our solution employs the Case‐Based Reasoning ( CBR ) approach with ELECTRE III , based on the Industry Classification Benchmark standards. The target stocks are ranked based on their similarities to a reference case, allowing specified selection criteria. Similarities are calculated based on selected ELECTRE III metrics. Experimental results with the Stock Exchange of Thailand data show that our CBR approach with ELECTRE III outperforms the traditional method.

Ultra-Wideband Low-Loss Switch Design in High-Resistivity Trap-Rich SOI With Enhanced Channel Mobility (2017)

In this paper, the stress memorization technique (SMT) effects upon ultra-wideband RF switch performance are investigated for the first time. Low insertion loss (IL), high isolation, ultra-wideband (dc to 50 GHz) single-pole double-throw (SPDT), and single-pole four-throw (SP4T) switches designed with commercial 0.13- <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> high-resistivity (HR) trap-rich SOI technology with/without SMT are presented and investigated. 2.5 V nMOS transistor ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$L_{g} = 0.2~\mu \text{m}$ </tex-math></inline-formula> ) with low <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$R_{\mathrm{\scriptscriptstyle ON}} {^\ast} C_{\mathrm{\scriptscriptstyle OFF}}$ </tex-math></inline-formula> from GF 130RFSOI PDK is used. It is found that channel mobility of switch transistor is improved by SMT and thus switch performance can be further improved. Moreover, the impact of transistor channel length, which has dominant effects on both IL and isolation of the switches, under different gate bias on switch performance are also studied and verified experimentally. Low measured IL of less than 2.1 dB and good isolation of better than 27 dB from dc to 50 GHz are obtained for the SPDT switch. For SP4T switch, the measured IL of less than 2.6 dB and isolation of better than 27 dB are achieved from dc to 35 GHz. The active chip areas of designed SPDT and SP4T switches are compact with size of only <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$0.214 \times 0.19~\text {mm}^{2}$ </tex-math></inline-formula> and <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$0.36 \times 0.19~ \text {mm}^{2}$ </tex-math></inline-formula> , respectively.

Comparison Study of Traffic Signs Recognition Using Deep Learning Architectures (2022)

Self-driving vehicles are considered one of the most significant advanced technologies in computer science and artificial intelligence. The primary objective of autonomous driving is the elimination of human supervision from the workflow of autonomous cars. The advantages of this technology are to improve people’s lives by minimizing traffic, eliminating parking spaces in cities, boosting collective fuel efficiency, and lowering accidents. As autonomous driving becomes more incorporated into our daily lives, effective solutions are essential to its challenges. One of the most important tasks for autonomous driving is the automatic recognition of traffic signs. Artificial intelligence is broadly used in the object detection fields and especially in traffic sign detection tasks, while Convolutional Neural Networks (CNNs) are utilized in many computer vision tasks. In this paper, we conduct a comparison study of object recognition challenges for self-driving automobiles, in particular for traffic signs and traffic signals detection. Two standard datasets and six different deep CNNs architectures are utilized to carry out experiments. The data augmentation method is employed to solve the unbalanced datasets problem. Experiments show that for the GTSRB dataset, the DenseNet201 model with Adam optimizer achieved the top accuracy (98.66%). For the LISA TL dataset, the InceptionResNetV2 model with Adam optimizer achieved the highest accuracy among the other networks (98.84%).
Partial-MDS Codes and Their Application to RAID Type of Architectures (2013)

A family of codes with a natural 2-D structure is presented, inspired by an application of redundant arrays of independent disks (RAID) type of architectures whose units are solid-state drives (SSDs). Arrays of SSDs behave differently from arrays of hard disk drives, since hard errors in sectors are common and traditional RAID approaches (like RAID 5 or RAID 6) may be either insufficient or excessive. An efficient solution to this problem is given by the new codes presented, called partial maximum distance separable (PMDS) codes.
The non-centrosymmetric layered compounds IrTe2I and RhTe2I (2022)

The previously unreported layered compounds IrTe<sub>2</sub>I and RhTe<sub>2</sub>I were prepared by a high-pressure synthesis method. Single crystal X-ray and powder X-ray diffraction studies find that the compounds are isostructural, crystallizing in a layered orthorhombic structure in the non-centrosymmetric, non-symmorphic space group <i>Pca</i>2<sub>1</sub> (#29). Characterization reveals diamagnetic, high resistivity, semiconducting behavior for both compounds, consistent with the +3 chemical valence and <i>d</i><sup>6</sup> electronic configurations for both iridium and rhodium and the Te-Te dimers seen in the structural study. Electronic band structures are calculated for both compounds, showing good agreement with the experimental results.
Cross-spectrally pure light and the spectral modulation law (1997)

Mandel's concept of cross-spectral purity is generalized to apply not only to certain kinds of beams, but also to some fields in three-dimensional regions of space. Examples of such fields are given. The results also provide justification for the use of the so-called reduction formula for cross-spectrally pure beams in previous analysis of the Hanbury-Brown-Twiss experiments, relating to the determination of the degree of coherence of light from photoelectric measurements.
The Use of Spark Plasma Sintering to Fabricate a Two-phase Material from Blended Aluminium Alloy Scrap and Gas Atomized Powder (2015)

Recently innovative solid state / ‘meltless’ recycling techniques have been developed and proposed for the consolidation of aluminium alloy scrap, aiming both at energy and material savings by eliminating the melting step. In this context, a powder metallurgy route is examined as a solid state recycling technique for the fabrication of a two-phase material via Spark Plasma Sintering. By mixing aluminium atomized powder and machining chips of the same alloy, a two-phase material was produced, where the powder phase acts as a binder/matrix for the Al scrap. Hardness, density, compression testing along with microstructural and computed tomography analysis of the densified Al 6061 alloy are presented.
Inferences About the Early Moon from Gravity and Topography (1998)

Recent spacecraft missions to the Moon have significantly improved our knowledge of the lunar gravity and topography fields, and have raised some new and old questions about the early lunar history. It has frequently been assumed that the shape of the Moon today reflects an earlier equilibrium state and that the Moon has retained some internal strength. Recent analysis indicating a superisostatic state of some lunar basins lends support to this hypothesis. On its simplest level, the present shape of the Moon is slightly flattened by 2.2 +/- 0.2 km while its gravity field, represented by an equipotential surface, is flattened only about 0.5 km. The hydrostatic component to the flattening arising from the Moon's present day rotation contributes only 7 m. This difference between the topographic shape of the MOon and the shape of its gravitational equipotential has frequently been explained as the memory of an earlier moon that was rotating faster and had a correspondingly larger hydrostatic flattening. To obtain this amount of hydrostatic flattening from rotation alone, and accounting for the contribution of the present-day gravity field, the Moon's rotation rate would need to be about 15x greater than at present, leading ot a period of < 2 days. Maintaining its synchronous rotation with Earth would require a radius for the Moon's orbit of approximately 9 Earth Radii. Unfortunately, our confidence in the observed lunar flattening is not as great as we would like. The uncertainty of .02 km may not properly reflect the limitations of the Clementine dataset, which did not sample poleward of latitudes 81 N and 79 S. Also, the large variation of topography +/- 8 km seen on the MOon dwarfs our estimate fo the flattening. Further the lunar south pole is on the edge of, or possibly inside the massive deep, South Pole-Aitken Basin. Thus, polar radii could be underestimated. This would yield a smaller flattening, which would imply a greater lunar rotation period and orbital radius. However, Basin compensation states and analyses of support and relaxation of topography at long wavelengths point to a lunar shape that has retained a flattening from an earlier faster rotation period.
Quantum interference with photon pairs created in spatially separated sources (2003)

We report on a quantum interference experiment to probe the coherence between two photons coming from nondegenerate photon pairs at telecom wavelength created in spatially separated sources. The two photons are mixed on a beam splitter and we observe a reduction of up to 84% in the net coincidence count rate when the photons are made indistinguishable. This experiment constitutes an important step towards the realization of quantum teleportation and entanglement swapping with independent sources.
The higher the decrease in the standardized uptake value of positron emission tomography after chemoradiation, the better the survival of patients with gastroesophageal adenocarcinoma (2009)

The greater the decline in SUV after chemoradiation, the longer is the OS of gastroesophageal adenocarcinoma patients. The percentage SUV decrease as a continuous variable is a better prognosticator of OS than its dichotomized assessments.
Controlled manipulation of the Co–Alq3 interface by rational design of Alq3 derivatives (2016)

Recently, research has revealed that molecules can be used to steer the local spin properties of ferromagnetic surfaces. One possibility to manipulate ferromagnetic-metal-molecule interfaces in a controlled way is to synthesize specific, non-magnetic molecules to obtain a desired interaction with the ferromagnetic substrate. Here, we have synthesized derivatives of the well-known semiconductor Alq<sub>3</sub> (with q = 8-hydroxyquinolinate), in which the 8-hydroxyquinolinate ligands are partially or completely replaced by similar ligands bearing O- or N-donor sets. The goal of this study was to investigate how the presence of (i) different donor atom sets and (ii) aromaticity in different conjugated π-systems influences the spin properties of the metal-molecule interface formed with a Co(100) surface. The spin-dependent metal-molecule-interface properties have been measured by spin-resolved photoemission spectroscopy, backed up by DFT calculations. Overall, our results show that, in the case of the Co-molecule interface, chemical synthesis of organic ligands leads to specific electronic properties of the interface, such as exciton formation or highly spin-polarized interface states. We find that these properties are even additive, i.e. they can be engineered into one single molecular system that incorporates all the relevant ligands.
Asymptotic gaps between BP decoding and local-MAP decoding for low-density parity-check codes (2008)

In this paper, we consider communication over the binary erasure channel (BEC) using low-density parity-check (LDPC) codes. We consider MAP decoding not using a whole Tanner graph but only a neighborhood graph of fixed depth referred to as local-MAP decoding for deriving lower bounds of the error probability under message-passing decoding and bit-flipping decoding. The main result of this paper is to derive an asymptotic performance for regular ensembles under local-MAP decoding and to derive an asymptotic gap of the bit error probability between belief propagation (BP) and local-MAP decoding for irregular ensembles. Finally, we show the limit of the scaling parameter of these decodings when number of iterations tends to infinity.
Improvement in Quality‐of‐Life Measures and Stimulation of Weight Gain After Treatment with Megestrol Acetate Oral Suspension in Geriatric Cachexia: Results of a Double‐Blind, Placebo‐Controlled Study (2000)

In geriatric patients with weight loss or low body weight MA improves appetite and well-being after 12 weeks of treatment. During the 3 months of MA treatment, there was no statistically significant weight gain (> or =4 lbs). Three months after treatment, weight gain (> or =4 lbs) was significantly increased in MA-treated patients.

Contrast-enhanced MR imaging of malignant brain tumors. (1986)

Magnetic resonance (MR) imaging was performed before and serially after intravenous injection of 1 mmol/kg gadolinium-DTPA (Schering) in 17 patients with clinical and histologic diagnosis of malignant cerebral tumors. There was a decrease of 1% in T1 and 10% in T2 in normal white matter and a decrease of 8% in T1 and 14% in T2 in normal gray matter. Contrast enhancement was observed in 16 of the 17 tumors. In the region of maximal enhancement a mean decrease of 16% in T1 was observed in low-grade gliomas, a mean decrease in T1 of 29% was seen in high-malignancy gliomas, and a mean decrease in T1 of 33% was observed in metastases. The decreases in T1 persisted for at least 50 min. In one case the central cystic region of the tumor displayed a decrease in T1 and T2. Measurements of signal intensity displayed maximal contrast enhancement with an IR 1500/500/44 sequence, much less with SE 1500/44, and least with SE 1500/80. Edema was observed on precontrast images in 14 cases, but satisfactory definition of the tumor-edema margin was only possible in four cases. After contrast enhancement this margin was defined in 10 cases. In four of the 17 cases areas of apparent "edema" seen before administration of Gd-DTPA displayed significant contrast enhancement and probably represented tumor infiltration. Comparison with CT showed a greater degree of contrast enhancement on MR images in eight cases, an equal degree in eight cases, and greater enhancement on CT in one case.(ABSTRACT TRUNCATED AT 250 WORDS)
Three-dimensional display with optimized view distribution (2019)

A three-dimensional (3-D) display with optimized view distribution is proposed. The proposed 3-D display consists of a two-dimensional (2-D) display panel, a pixel mask, and a lenticular lens. The 2-D display panel is used to provide parallax images. The pixel mask has a designed pinhole array and is located close to the 2-D display panel. This pinhole array can modulate the location and size of the pixels on the 2-D display panel to provide an optimized view distribution. Finally, the lenticular lens projects the pixels in different spatial directions to form 3-D images. Different from conventional 3-D displays, the proposed 3-D display can concentrate views into the center area and form a better parallax continuity. A prototype of the proposed 3-D display is developed. Experiment results agree well with the theory.
