Mauna Kea, Hawaii, as an Analog Site for Future Planetary Resource Exploration: Results from the 2010 ILSO-ISRU Field-Testing Campaign (2012)

The major advances in knowledge of extraterrestrial bodies come from in situ measurements on robotized measuring devices deployed by international space missions, for example, on the Moon and Mars. It is essential to test these instruments in environments on Earth that bear a close resemblance to planetary conditions. Within the framework of the 2010 International Lunar Surface Operation In Situ Resource Utilization (2010 ILSO-ISRU) Analog Test, a suite of scientific instruments developed for in situ lunar research was field tested and calibrated on the Mauna Kea volcano in Hawaii on January 27 to February 11, 2010. This site will be used as one of the future standard test sites to calibrate instruments for in situ lunar research. In 2010, a total of eight scientific teams tested instrument capabilities at the test site. In this paper, a geological setting for this new field-test site, a description of the instruments that were tested during the 2010 ILSO-ISRU field campaign, and a short discussion of each instrument about the validity and use of the results obtained during the test are provided. These results will serve as reference for future test campaigns.
HPIPE: Heterogeneous Layer-Pipelined and Sparse-Aware CNN Inference for\n FPGAs (2020)

We present both a novel Convolutional Neural Network (CNN) accelerator\narchitecture and a network compiler for FPGAs that outperforms all prior work.\nInstead of having generic processing elements that together process one layer\nat a time, our network compiler statically partitions available device\nresources and builds custom-tailored hardware for each layer of a CNN. By\nbuilding hardware for each layer we can pack our controllers into fewer lookup\ntables and use dedicated routing. These efficiencies enable our accelerator to\nutilize 2x the DSPs and operate at more than 2x the frequency of prior work on\nsparse CNN acceleration on FPGAs. We evaluate the performance of our\narchitecture on both sparse Resnet-50 and dense MobileNet Imagenet classifiers\non a Stratix 10 2800 FPGA. We find that the sparse Resnet-50 model has\nthroughput at a batch size of 1 of 4550 images/s, which is nearly 4x the\nthroughput of NVIDIA's fastest machine learning targeted GPU, the V100, and\noutperforms all prior work on FPGAs.\n
Rapid Bacterial Identification, Resistance, Virulence and Type Profiling using Selected Reaction Monitoring Mass Spectrometry (2015)

Mass spectrometry (MS) in Selected Reaction Monitoring (SRM) mode is proposed for in-depth characterisation of microorganisms in a multiplexed analysis. Within 60-80 minutes, the SRM method performs microbial identification (I), antibiotic-resistance detection (R), virulence assessment (V) and it provides epidemiological typing information (T). This SRM application is illustrated by the analysis of the human pathogen Staphylococcus aureus, demonstrating its promise for rapid characterisation of bacteria from positive blood cultures of sepsis patients.
Decision Tree (2018)

In the previous chapters, we’ve considered regression-based algorithms that optimize for a certain metric by varying coefficients or weights. A decision tree forms the basis of tree-based algorithms that help identify the rules to classify and forecast an event or variable we are interested in. Moreover, unlike linear or logistic regression, which are optimized for either regression or classification, decision trees are able to perform both.
Hybrid piezoelectric-magnetic neurons (2018)

This paper proposes a spintronic neuron structure composed of a heterostructure of magnets and a piezoelectric with a magnetic tunnel junction (MTJ). The operation of the device is simulated using SPICE models. Simulation results illustrate that the energy dissipation of the proposed neuron compared to that of other spintronic neurons exhibits 70% improvement. Compared to CMOS neurons, the proposed neuron occupies a smaller footprint area and operates using less energy. Owing to its versatility and low-energy operation, the proposed neuron is a promising candidate to be adopted in artificial neural network (ANN) systems.

Characterization and structure of a fiber of BaO–SnO–P2O5–B2O3glass with a very small photoelastic constant (2018)

The optical properties of a BaO–SnO–P2O5–B2O3 glass fiber with a very small photoelastic constant are characterized, and its phosphate and borate structure is studied via micro Raman and 31P and 11B magic-angle-spinning nuclear magnetic resonance spectrometry. The characteristics of the lead-free borophosphate fiber are equivalent to those of the developed lead silicate fiber used as an optical component in current transducers. The azimuth of polarized light is maintained through the new fiber with a very small photoelastic constant, which represents a potential new current transducer without hazardous elements. The elucidated structural units of the fiber are pyro- and metaphosphates and tetrahedral borate, which resemble the structural units of a preform glass.
Estimation of Acute Blood Loss in the Anticoagulated Rabbit Model Using 3 Modalities of Radio Frequency Energy Ablation (2003)

Megahertz DC-to-DC converters controlled by an amorphous core (1983)

A compact DC-to-DC converter operating at megahertz region is constructed employing a very small amorphous core in the base drive circuit. The driving method of this converter is based on the transistorcore multivibrator, in which the current and the voltage feedback are combined. The multivibrator is synchronized with an external pulse, The amorphous core used is of two layers of a narrow Co-rich ribbon. Static characteristics are examined on the forward converter with this drive circuit. The efficiency of 81% is obtained with bipolar transistors at 1MHz.
Copolymerization of carbon dioxide with propylene oxide catalyzed by poly(p‐hydroxystyrene)/diethylzinc system (1978)

Abstract A polymeric catalyst prepared from poly[1‐(4‐hydroxyphenyl)etylene] ( 1 ), and Zn(C 2 H 5 ) 2 was found to be effective for the copolymerization of carbon dioxide and 1,2‐epoxypropane. The highest activity was observed when a mole ratio of phenolic hydrogen in 1 to Zn(C 2 H 5 ) 2 equal to unity was applied in contrast to the catalysts so far reported. The structure of the catalyst after the copolymerization was determined by IR and H 1 NMR spectroscopy. A Zn—C 2 H 5 bond in this system was confirmed to be the active center. A possible inactivation process of the catalyst is proposed.
Whispering gallery mode emission from dye-doped polymer fiber cross-sections fabricated by near-field electrospinning (2020)

Whispering gallery mode (WGM) resonators demonstrate great potential for photonic and sensing applications. Yet, these devices are often disadvantaged by costly materials or complex fabrication approaches, in addition to lack of manufacturing scalability. Near-field electrospinning (NFES), a recently emerged facile fiber fabrication method, offers a solution. Here, WGM resonances are reported in Rhodamine 6G-doped poly(vinyl) alcohol (PVA) microfibers via NFES. Diameters are tuned over a range of more than 10 μm by varying substrate stage speed. Fibers display uniform distribution of dye, smooth surfaces, and circular cross-sections, all critical for supporting WGMs. High quality (Q) resonances are confirmed within fiber cross-sections through polarization experiments, free-spectral range analysis, and Mie-theory-derived mode assignment. In addition to WGMs, groups of associated spiral or conical modes are observed due to taper-induced weak optical confinement along the fiber axis. Crosslinked, dye-doped PVA fibers are utilized to sense the ethanol concentration in ethanol-water mixtures and actuation mechanisms are evaluated by comparison to theoretical spectra. The demonstration of high-Q resonances within NFES polymer microfibers is a critical step toward simple, cost effective, high-volume fabrication of WGM resonators for optoelectronics and biomedical devices.

Putative TetR Family Transcriptional Regulator SCO1712 Encodes an Antibiotic Downregulator in Streptomyces coelicolor (2010)

A tetR family transcriptional regulatory gene (SCO1712) was identified as a global antibiotic regulatory gene from a Streptomyces interspecies DNA microarray analysis. SCO1712 disruption in Streptomyces coelicolor not only upregulated antibiotic biosynthesis through pathway-specific regulators when a previously identified pleiotropic downregulatory wblA was expressed but also further stimulated antibiotic production in a wblA deletion mutant, implying that SCO1712 might encode a novel antibiotic downregulator.
GC-TOF/MS-Based Metabolomics for Comparison of Volar and Non-Volar Skin Types (2022)

Skin has heterogenous identities on different body sites despite similar cellular compositions. There are two types of skin, volar (palmoplantar) and non-volar (dorsal), which are characterized by epidermal thickness, pigmentation, and presence of hair follicles. However, the mechanisms underlying the development of these different skin types remain unclear. To investigate these, we profiled the cellular metabolites of volar and non-volar skin in mice using gas chromatography-time-of-flight/mass spectrometry (GC-TOF/MS), and further assessed the metabolic differences between them. In total, 96 metabolites from both volar and non-volar skin of mice were identified using the BinBase database system. Metabolomics analysis revealed important differences associated with amino acid metabolism (phenylalanine, tyrosine, and tryptophan biosynthesis; aspartate and glutamate metabolism), sugar metabolism (pentose phosphate pathway), and nucleotide metabolism (pyrimidine metabolism) in volar skin. Fifty metabolites were identified as potential biomarkers differentiating the physiological characteristics of these skin types. Of these, nine were highly increased whereas 41 were significantly decreased in volar skin compared with those in non-volar skin. Overall, these results provide valuable information for understanding the metabolic differences between volar and non-volar skin.
Selective Anion Complexation by a Calix[4]pyrrole Investigated by Monte Carlo Simulations (1999)

The complexation of anions by octamethylcalix[4]pyrrole 1 and 2,5-dimethylpyrrole has been investigated by energy minimizations in the gas phase and by Monte Carlo (MC) simulations in dichloromethane using the OPLS force field. In agreement with experiment, the 1,3-alternate conformation of 1, in which adjacent pyrrole rings are pointing in opposite directions, was shown to be the most stable conformation in the absence of a halide anion. The cone conformer of 1, having all pyrrole units in a parallel orientation, is not stable in the absence of a halide anion, but it is the most stable conformation upon anion binding due to the formation of four NH−halide hydrogen bonds. The relative free energies of binding of chloride, bromide, and iodide with the cone of 1 in dichloromethane are calculated with free energy perturbation (FEP) simulations to be in excellent agreement with experiment. However, the calculations predict a far greater affinity for fluoride ion than was measured. This can be explained by the presence of trace amounts of water. For reference, MC/FEP calculations were also carried out for 2,5-dimethylpyrrole, which was predicted to bind only fluoride ion, consistent with NMR experiments. On the technical side, the MC sampling efficiency of alternative internal-coordinate representations of the complexes was also considered.

Novel Functionality and Material for Si-Photonics: Two-Photon Absorption Switching and Antimonide Hetero-Genius Epitaxy (2007)

Novel functionality and material were developed for Si-photonics in this study. Ultra-fast silicon all optical switches using two-photon absorption (TPA) were developed in silicon nanowire optical waveguide on silicon-on-insulator substrate. This waveguide can produce high optical intensities that yield optical nonlinearity such as TPA even at input optical powers typically used in fiber optic communication systems. In addition, we fabricated a GaSb based quantum well (QW) on a Si substrate. The emission wavelength of QW was 1.55 μm at room temperature, so that the new function can be developed on Si-photonics using this QW.
Analysis of LC−MS Data for Characterizing the Metabolic Changes in Response to Radiation (2010)

Recent advances in mass spectrometry-based metabolomics have created the potential to measure the levels of hundreds of metabolites that are the end products of cellular regulatory processes. In this study, we investigate the metabolic changes in genetically engineered cell lines in response to radiation exposure. "Shrinkage t" statistic and partial least-squares-discriminant analysis methods are utilized to identify peaks whose signal intensities were significantly altered by radiation. This is accomplished through pairwise comparison of radiation treated cell lines at various time points following radiation against untreated cell lines. A pathway analysis is performed following identification of the metabolites represented by the selected peaks. The results indicate an ATM regulated induction of major pathways in response to radiation treatment.
Hierarchically Surface‐Textured Ultrastable Hybrid Film for Large‐Scale Triboelectric Nanogenerators (2020)

Abstract The supply of electrical power is indispensable in the internet of things (IoT) area. Triboelectric nanogenerators (TENGs) has been largely used as a power supply due to simple device structure and various possibilities of material selection. Although various surface modifications of TENG are utilized for improving the output performance of TENG, these methods have significant drawbacks of high‐cost fabrication process, limited device size, and wearing out. Here, a mechanically robust TENG using a newly developed surface‐textured glass fabric reinforced siloxane hybrid film (SGH film) is presented. The large‐scale SGH film is cost‐effectively fabricated via a simple roll‐to‐plate and UV curing process. The film is repeatedly duplicated over 100 times using one pre‐treated substrate mold. SGH film exhibits superior thermal and mechanical stability, compared to other polymer films. Finally, surface textured TENG (THTENG) is achieved using extremely stable SGH film, resulting in enhanced output power compared to flat TENG and high durability during the 100 000 cycles of TENG operation.
Highly accurate radio environment mapping method based on transmitter localization and spatial interpolation in urban LoS/NLoS scenario (2018)

In this paper, we propose a mapping method that can accurately visualize a radio environment by using fixed and distributed spectrum sensors in a mixed situation of line of sight and none line of sight in an urban scenario. The proposed radio environment map (REM) construction method adopts a hybrid algorithm of maximum-likelihood-estimation-based localization and Kriging-based spatial interpolation. As a result of Monte-Carlo simulation, interpolation accuracy of the REMs could be improved by 9.4 dB at the maximum, compared to the conventional method. The result indicates that our approach can effectively determine the sharing condition of spectrum use while reliably protecting primary wireless systems.
EAWA: Energy-Aware Workload Assignment in Data Centers (2018)

One of the challenges that today's cloud computing infrastructures, and more specifically data centers, are struggling with is related to their energy consumption. Information technology (IT) equipment and cooling infrastructure are key parts of the total energy expenditure in a data center. A considerable amount of power is wasted due to workload management inefficiencies and the lack of coordination between cooling units and IT equipment. In this paper, server differences in terms of their cooling requirements and power consumption are taken into account for workload distribution. An optimal workload assignment problem that takes both server power consumption and thermal models into account is formulated. A simple low complexity algorithm is proposed. The algorithm not only assigns workload but it also adjusts the cooling unit set-point accordingly. Results show that the proposed algorithm can significantly reduce the total power consumed in a data center, in particular when compared to the uniform workload distribution algorithm.

Microstructure and Reliability of Tin-Silver Micro-Copper Pillar Assemblies (2018)

Abstract IBM engineers recently conducted a study to better understand and control the reliability of copper pillar solder joints in 2.5-D packages. Here they describe their approach and the results they obtained. They explain how they created test samples to evaluate different solder compositions, pillar geometries, and thermal histories and assess their effect on microstructure, precipitate morphology, intermetallic layer thickness, and shear strength. They also present thermal cycling test results comparing the performance of silicon and glass interposers.
On the set of images modulo viewpoint and contrast changes (2009)

We consider regions of images that exhibit smooth statistics, and pose the question of characterizing the "essence" of these regions that matters for recognition. Ideally, this would be a statistic (a function of the image) that does not depend on viewpoint and illumination, and yet is sufficient for the task. In this manuscript, we show that such statistics exist. That is, one can compute deterministic functions of the image that contain all the "information" present in the original image, except for the effects of viewpoint and illumination. We also show that such statistics are supported on a "thin" (zero-measure) subset of the image domain, and thus the "information" in an image that is relevant for recognition is sparse. Yet, from this thin set one can reconstruct an image that is equivalent to the original up to a change of viewpoint and local illumination (contrast). Finally, we formalize the notion of "information" an image contains for the purpose of viewpoint- and illumination- invariant tasks, which we call "actionable information" following ideas of J. J. Gibson.
