Diversity of methanogenic archaea from the 2012 terrestrial hot spring (Valley of Geysers, Kamchatka) (2016)

Archaeal diversity in the 2012 terrestrial hot spring (Valley of Geysers, Kronotsky Nature Reserve, Kamchatka, Russia) was investigated using molecular and cultivation-based approaches. Analysis of the 16S rRNA gene sequences revealed predominance among archaea of uncultured microorganisms of the pSL12 and THSCG clusters. Analysis of the mcrA genes revealed that members of the order Methanomassiliicoccales were predominant (68%) among methanogens; the latter constituted 0.15% of the total number of archaea. Five stable thermophilic methanogenic associations utilizing hydrogen, formate, acetate, or methanol as substrates were obtained from the sediments of spring 2012. The diversity of cultured methanogens was limited to members of the genera Methanothermobacter, Methanothrix, and Methanomethylovorans. The association growing at 65°C and producing methane from methanol contained two components, which probably formed a syntrophic relationship: a Methanothermobacter methanogenic archaeon and a bacterium representing an separate cluster within the Firmicutes phylum, which was phylogenetically related to the genera Thermacetogenium and Syntrophaceticus. These data indicate high diversity of methanogens, notwithstanding their low abundance among archaea. The group of thermophilic Methanomassiliicoccales, which predominated among methanogens, is of special interest.

오늘날 눈부시게 발전한 과학으로 인하여 우리는 합리적이고 편안한 삶을 살아가게 되었다. 하지만 우리 삶의 곳곳에는 과학과는 상반되는 길상(吉祥)의 표현이 많이 남아 있다. 유추해 보면 본래 인간은 불완전한 존재로써 안정된 삶의 영위(營爲)를 바라는 욕구가 있다는 것을 알 수 있다. 태고부터 현재까지 이러한 원초적이면서 간절한 염원의 상징적 이미지로 표출된 것이 부적이다. 본 연구에서는 벽사부적에 나타나는 형태와 색채의 분석을 통하여 그 의미를 고찰하는데 연구목적을 가지고 있다. 또한 연구범위를 대표적인 벽사부적으로 한정하여 선행연구와 문헌자료를 통하여 벽사부적의 의미와 종류를 고찰하고 부적의 속성을 파악하여 보았다. 그리고 벽사부적에 나타나는 형태와 색채를 나누어 분석하였다. 연구결과 벽사부적에서의 형태는 특정한 기호와 문자로 구성되어 가독성 보다는 신비함과 주술성을 강조하였다. 그리고 색채는 색의 아름다움과 조화보다는 상징의미 부여 역할에 더 큰 특징이 있다는 것을 알 수 있었다. 이는 자연의 흐름에 순응하며, 자연과 인간의 관계를 친밀하게 생각하는 음양오행사상(陰陽五行四象)에 기반을 둔 오방색과 유사한 모습을 보여준다.

Enhanced Activity and Selectivity in Catalytic Methanol Steam Reforming by Basic Alkali Metal Salt Coatings (2013)

Tri-salts added: Pt on alumina catalysts can be used for converting methanol and water into hydrogen and carbon dioxide (see picture), for applications such as hydrogen storage. Both the activity and selectivity could be enhanced by coating these materials with a thin layer of a molten salt mixture of Li/K/Cs acetate. Potassium doping was identified by DRIFTS measurements to be an important factor for the boost in catalyst performance.
Amelioration of Ischemic Brain Injury in Rats with Human Umbilical Cord Blood Stem Cells: Mechanisms of Action (2016)

Despite the high prevalence and devastating outcome, there remain a few options for treatment of ischemic stroke. Currently available treatments are limited by a short time window for treatment and marginal efficacy when used. We have tested a human umbilical cord blood-derived stem cell line that has been shown to result in a significant reduction in stroke infarct volume as well as improved functional recovery following stroke in the rat. In the present study we address the mechanism of action and compared the therapeutic efficacy of high- versus low-passage nonhematopoietic umbilical cord blood stem cells (nh-UCBSCs). Using the middle cerebral arterial occlusion (MCAo) model of stroke in Sprague–Dawley rats, we administered nh-UCBSC by intravenous (IV) injection 2 days following stroke induction. These human cells were injected into rats without any immune suppression, and no adverse reactions were detected. Both behavioral and histological analyses have shown that the administration of these cells reduces the infarct volume by 50% as well as improves the functional outcome of these rats following stroke for both high- and low-passaged nh-UCBSCs. Flow cytometry analysis of immune cells present in the brains of normal rats, rats with ischemic brain injury, and ischemic animals with nh-UCBSC treatment confirmed infiltration of macrophages and T cells consequent to ischemia and reduction to normal levels with nh-UCBSC treatment. Flow cytometry also revealed a restoration of normal levels of microglia in the brain following treatment. These data suggest that nh-UCBSCs may act by inhibiting immune cell migration into the brain from the periphery and possibly by inhibition of immune cell activation within the brain. nh-UCBSCs exhibit great potential for treatment of stroke, including the fact that they are associated with an increased therapeutic time window, no known ill-effects, and that they can be expanded to high numbers for, and stored for, treatment.
VanderLugt correlator and neural networks (2003)

Several experimental demonstrations of neural networks using coherent optics are demonstrated. An associative memory for word-break recognition and a learning machine for multicategory classification are discussed. Finally, a compact and robust coherent optical processor using a recently developed SELDA (surface emitting micro-laser diode array) is described. Although the applications are different, all these implementations are based on the VanderLugt correlator.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
A 2/3″ 9.5 Mpixel CMOS Imager with High Frame Rate and HDR Capabilities (2020)

Requirements for live sports production in 4K UHD resolution and high dynamic range (HDR) have multiple challenges for the imaging technology. First and foremost, the high pixel count on any given 2/3″ imager size reduces the pixel size to a critical level, while allowing for enough sensitivity and dynamic range required for many different shooting conditions. In addition, stretching the requirements even further, we have high-speed cameras fully integrated into the production workflow supporting native 4K UHD resolution as well as support for the different HDR formats used in live production. — An increase in frame rate increases the bandwidth requirements with the same factor and going from single speed to 3X or 6X speed requires clock rates exceeding the capabilities of the typical 2/3″ imagers used today. The imager presented in this paper demonstrates an architecture that supports high spatial and high temporal resolution and a high output data rate. The sensor is manufactured in a 110/180 nm CMOS process and supports a pixel rate of 3.6 Gpix/s, which translates to an output data rate of 58 Gb/s. The imager uses 4T-4shared pixels in combination with kTC-noise suppression by Digital Double Sampling (DDS) and one 16-bit ADC for each column of the shared pixels. This translates to 2112 ADC outputs which has to be multiplexed and serialized to 16 parallel outputs in 32 LVDS lanes at 1.8 Gb/s for which sixteen 132:1 multiplexers are needed. — To meet the lag performance for demanding live broadcast applications, typically a transfer time of <1 μs is needed. For high frame rate at full resolution, the available time for column settling and A/D conversion makes it impossible to meet this requirement without addressing multiple rows at the same time. To fulfill the transfer time requirements, an innovative row addressing scheme has been developed to toggle between the different rows. — This paper will explain the architecture and readout schemes used to realize a 2/3″ 9.5Mpixel CMOS imager with 3.6 Gpix/s enabling high frame-rate operation in native 4K UHD resolution and full HDR support.
Landing posture control via trajectory planning for a generalized twin-body system (2009)

For the purpose of preventing a free-falling object from damage, this study is devoted to the landing posture control via trajectory planning for a generalized twin-body system by employing the methods of PD and sliding control. The system discussed herein is the simplified model of a free-falling cellular phone with two rotational DOFs. In this paper, the governing equations of the system are first established based on the Lagrange-Euler formulation. Then, PD and sliding controllers are designed to achieve the desired landing posture. In addition, the trajectory planning is adopted to reduce the input energy. The performance of the controller is validated by MATLAB simulations, and the relations between input energy, trajectory-function, and falling height are discussed.

Adrenal responses of Angus x Hereford cattle to the stress of weaning. (1995)

To test adrenal responsiveness of beef cattle to stress, plasma norepinephrine, epinephrine, and cortisol responses of Angus x Hereford cattle to weaning were measured in blood samples taken from 1) eight cows and their 4- to 6-mo-old calves before and after separation and, the following day, before and after being reunited and 2) an equal number of control animals. After separation and before they were reunited, dams were returned to their original pen and calves to an adjacent pen. Experimental trials were conducted every 2 wk and included two cow/calf pairs per trial. Norepinephrine concentrations tended to increase in calves after separation, were increased (+82 pg/mL, P < .01) on the 2nd d before animals were reunited, and decreased (-88 pg/mL, P < .01) after animals were reunited. Epinephrine concentrations tended to increase in calves after separation, were increased in calves (+128 pg/mL, P < .001) and dams (+104 pg/mL, P < .001) on the 2nd d before animals were reunited, and decreased after calves (-162 pg/mL, P < .001) and dams (-101 pg/ml, P < .001) were reunited. There were no significant effects of time on catecholamine concentrations for control animals. Cortisol concentrations for treated and control animals tended to increase in sequential samples each day; however, the increases were small (approximately 1 ng/mL) and concentrations remained low (> 5 ng/mL). In conclusion, peripheral catecholamine concentrations in beef calves and epinephrine concentrations in dams increased in response to stress associated with weaning and separation.(ABSTRACT TRUNCATED AT 250 WORDS)
A comparison of oligonucleotide and cDNA-based microarray systems (2004)

Large-scale public data mining will become more common as public release of microarray data sets becomes a corequisite for publication. Therefore, there is an urgent need to clarify whether data from different microarray platforms are comparable. To assess the compatibility of microarray data, results were compared from the two main types of high-throughput microarray expression technologies, namely, an oligonucleotide-based and a cDNA-based platform, using RNA obtained from complex tissue (human colonic mucosa) of five individuals. From 715 sequence-verified genes represented on both platforms, 64% of the genes matched in "present" or "absent" calls made by both platforms. Calls were influenced by spurious signals caused by Alu repeats in cDNA clones, clone annotation errors, or matched probes that were designed to different regions of the gene; however, these factors could not completely account for the level of call discordance observed. Expression levels in sequence-verified, platform-overlapping genes were not related, as demonstrated by weakly positive rank order correlation. This study demonstrates that there is only moderate overlap in the results from the two array systems. This fact should be carefully considered when performing large-scale analyses on data originating from different microarray platforms.
Hysteresis Compensation for Ground Contact Force Measurement With Shoe-Embedded Air Pressure Sensors (2016)

This paper reviews the design of smart shoes, a wearable device that measures ground contact forces (GCFs) for gait analysis. Smart shoes utilize four coils of silicone tubes adhered directly underneath the shoe insole at key points of interest. Air pressure sensors connect to each tube coil to measure pressure changes caused by compression. This paper presents static and dynamic calibration performed on each sensing coil to establish a model of internal pressure and the GCF. Based on the model, a phase lead filter is designed to account for the hysteresis effect and visco-elastic properties of the silicone tube in order to provide accurate GCF measurements. To design this filter, the air bladder is modeled using a standard linear solid (SLS) model. The prediction error minimization (PEM) algorithm is then implemented to identify the continuous-time transfer function of this SLS model, which is then transformed to discrete time domain to implement in a digital processor. Mechanical characterization and testing on a healthy subject are performed to validate the model and its capability to compensate for hysteresis in GCF measurement.

2D Monoelemental Germanene Quantum Dots: Synthesis as Robust Photothermal Agents for Photonic Cancer Nanomedicine (2019)

Abstract As a new family member of the emerging two‐dimensional (2D) monoelemental materials (Xenes), germanene has shown promising advantages over the prototypical 2D Xenes, such as black phosphorus (BP) and graphene. However, efficient manufacture of novel germanene nanostructures is still a challenge. Herein, a simple top‐down approach for the liquid‐exfoliation of ultra‐small germanene quantum dots (GeQDs) is presented. The prepared GeQDs possess an average lateral size of about 4.5 nm and thickness of about 2.2 nm. The functionalized GeQDs were demonstrated to be robust photothermal agents (PTAs) with outstanding photothermal conversion efficacy (higher than those of graphene and BPQDs), superior stability, and excellent biocompatibility. As a proof‐of‐principle, 2D GeQDs‐based PTAs were used in fluorescence/photoacoustic/photothermal‐imaging‐guided hyperpyrexia ablation of tumors. This work could expand the application of 2D germanene to the field of photonic cancer nanomedicine.
A Bioindicator for Verification of Thermal Processes for Particulate Foods (1988)

ABSTRACT A bioindicator was developed for verification of heat‐hold‐cool thermal processes for particulate foods. Spores of B. stearothermophilus were infused and immobilized within individual mushrooms using alginate gels. The particles were then made shelf‐stable by freeze‐drying. Results showed that thermal responses of bioindicator particles were similar to those for real particles; spores were successfully infused into the particle cold‐zones; and that spores were retained within particles through reconstitution and blanching. Results on thermal processing showed that these particles might be potentially useful indicators of sterility in continuous aseptic systems.
Multi-modal pedestrian detection with misalignment based on modal-wise regression and multi-modal IoU (2023)

Multi-modal pedestrian detection, which integrates visible and thermal sensors, has been developed to overcome many limitations of visible-modal pedestrian detection, such as poor illumination, cluttered background, and occlusion. By adopting the combination of multiple modalities, we can efficiently detect pedestrians even with poor visibility. Nevertheless, the critical assumption of multi-modal pedestrian detection is that multi-modal images are perfectly aligned. In general, however, this assumption often becomes invalid in real-world situations. Viewpoints of the different modal sensors are usually different. Then, the positions of pedestrians on the different modal images have disparities. We proposed a multi-modal faster-RCNN specifically designed to handle misalignment between two modalities. The faster-RCNN consists of a region proposal network (RPN) and a detector. We introduce position regressors for both modalities in the RPN and the detector. Intersection over union (IoU) is one of the useful metrics for object detection but is defined only for a single-modal image. We extend it into multi-modal IoU to evaluate the preciseness of both modalities. Our experimental results with the proposed evaluation metrics demonstrate that the proposed method has comparable performance with state-of-the-art methods and outperforms them for data with significant misalignment.
High-resolution printing of functional microdots by double-pulse laser-induced forward transfer (2015)

For high-resolution printing, we have developed a novel way of functional microdots deposition based on laser-induced forward transfer, which is referred to laser-induced dot transfer (LIDT). LIDT is one of promising additive manufacturing techniques because it can realize flexible patterning of micron and submicron-sized dots at atmospheric room-temperature conditions. Recently we have achieved printing of functional oxide microdots by a double-pulse LIDT with the first pulse for preheat and the second pulse for transfer, resulting in more precise control of laser-induced hightemperature and thermal-stress in a source film. In this paper, temporal temperature distributions during the transfer process have been investigated using a finite element method approach. High-resolution printing of functional microdots is promising for future optoelectronic integrations.

Technological Innovation and Industrial Decline: The Case of the Automatic Loom in the British Cotton Industry (2022)

Designing an automatic loom that replenishes weft mechanically without operative intervention challenged the ingenuity of engineers and technologists from the middle of the 19th century until about 1970, when further development ceased in favour of shuttleless alternatives. Although well established in the United States for manufacturing basic cotton fabrics by 1914, and sufficiently well advanced for producing a wide range of fabrics by 1930, the diffusion of the automatic loom in the British cotton industry was sluggish until the 1950s. The reasons are best understood by examining the operational prerequisites, provision of which in Britain was confounded by longstanding rigidities in accounting policy and industrial relations at the level of the firm, and in strategic management at the level of the industry. At the heart of this was the longevity of the traditional non-automatic Lancashire loom, both in design and operation. The article is a counterpoise to the orthodox economic analyses that tend to be dismissive of technological constructs.
Data from Increased Levels of Tetra-antennary <i>N</i>-Linked Glycan but Not Core Fucosylation Are Associated with Hepatocellular Carcinoma Tissue (2023)

&lt;div&gt;Abstract&lt;p&gt;&lt;b&gt;Background:&lt;/b&gt; Alterations in glycosylation have long been associated with the development of cancer. In the case of primary hepatocellular carcinoma (HCC), one alteration that has often been associated is increased amounts of fucose attached to the &lt;i&gt;N&lt;/i&gt;-glycans of serum proteins secreted by the liver.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Methods:&lt;/b&gt; In an effort to determine the origin of this increased fucosylation, we have conducted &lt;i&gt;N&lt;/i&gt;-linked glycan analysis of HCC tissue, the surrounding nontumor tissue, and compared this to tissue from a nondiseased adult liver.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Results:&lt;/b&gt; Surprisingly, no difference in the level of fucosylation was observed from the three donor groups, suggesting that the increased levels of fucosylation observed in serum of those with HCC is not the result of increased synthesis of fucosylated proteins in the cancer tissue. On the other hand, increased levels of a tetra-antennary glycan were observed in the HCC tissue as compared with the surrounding tissue or to the nondiseased livers.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Conclusions:&lt;/b&gt; This represents, to our knowledge, one of the first reports associating increased levels of branching with the development of HCC.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Impact:&lt;/b&gt; The identification of increased levels of tetra-antennary glycan on liver tumor tissue, as opposed to adjacent or nondiseased tissue may lead to improved detection of HCC. &lt;i&gt;Cancer Epidemiol Biomarkers Prev; 21(6); 925–33. ©2012 AACR&lt;/i&gt;.&lt;/p&gt;&lt;/div&gt;
