Transcriptomics of Mature Rice (Oryza Sativa L. Koshihikari) Seed under Hot Conditions by DNA Microarray Analyses (2020)

Higher temperature conditions during the final stages of rice seed development (seed filling and maturation) are known to cause damage to both rice yield and rice kernel quality. The western and central parts of Japan especially have seen record high temperatures during the past decade, resulting in the decrease of rice kernel quality. In this study, we looked at the rice harvested from a town in the central Kanto-plains (Japan) in 2010. The daytime temperatures were above the critical limits ranging from 34 to 38 °C at the final stages of seed development and maturity allowing us to investigate high-temperature effects in the actual field condition. Three sets of dry mature rice seeds (commercial), each with specific quality standards, were obtained from Japan Agriculture (JA Zen-Noh) branch in Ami-town of Ibaraki Prefecture in September 2010: grade 1 (top quality, labeled as Y1), grade 2 (medium quality, labeled as Y2), and grade 3 (out-of-grade or low quality, labeled as Y3). The research objective was to examine particular alterations in genome-wide gene expression in grade 2 (Y2) and grade 3 (Y3) seeds compared to grade 1 (Y1). We followed the high-temperature spike using a high-throughput omics-approach DNA microarray (Agilent 4 × 44 K rice oligo DNA chip) in conjunction with MapMan bioinformatics analysis. As expected, rice seed quality analysis revealed low quality in Y3 &gt; Y2 over Y1 in taste, amylose, protein, and fatty acid degree, but not in water content. Differentially expressed gene (DEG) analysis from the transcriptomic profiling data revealed that there are more than one hundred upregulated (124 and 373) and downregulated (106 and 129) genes in Y2 (grade 2 rice seed) and Y3 (grade 3 rice seed), respectively. Bioinformatic analysis of DEGs selected as highly regulated differentially expressed (HRDE) genes revealed changes in function of genes related to metabolism, defense/stress response, fatty acid biosynthesis, and hormones. This research provides, for the first time, the seed transcriptome profile for the classified low grades (grade 2, and out-of-grade; i.e., grade 3) of rice under high-temperature stress condition.

Preliminary Analysis of Morphology Change, Waves, and Currents for Navigation at Tillamook Inlet, Oregon (2013)

Abstract : This report documents preliminary investigations of morphologic change and numerical modeling of wave and current conditions that affect entrance channel navigation at Tillamook Inlet, Oregon. It is believed that unfavorable conditions are caused by a combination of three primary factors: a large ebb shoal, the Pacific coast high-energy wave climate, and a narrow dual-jetty entrance that forms a high current environment. A limited analysis of two bathymetry surveys for representative summer and winter months in 2005 and 2010 indicated that the geometry of ebb shoal outside the entrance of the inlet has been changing, exhibiting an asymmetric orientation relative to the entrance in 2005 which became symmetric by 2010. The historical morphologic evolution of the ebb shoal was evaluated in an attempt to determine possible relationships between the ebb shoal changes and changes to waves and currents in the entrance channel at Tillamook. The numerical modeling analysis was limited to one selected summer month and one winter month, with the sole purpose being the investigation of potential relationships between the geometry (shape, footprint, and elevation) of the ebb shoal and local wave and current conditions during these two selected months. Results indicated that both the geometry of ebb shoal and the entrance jetties together influence the magnitude of waves and currents at the inlet area (through the entrance channel and over the shoal). The two jetties forming the narrow inlet entrance played a critical role in the evolution of the ebb shoal, controlling the spatial variation and severity of waves and currents at the entrance and over the ebb shoal. Wave conditions at Tillamook Inlet may be improved by changing the geometry of the ebb shoal or jetties or both.
Experimental Verification and Graphical Characterization of Dynamic Jamming in Frictional Rigid-Body Mechanics (2007)

The dynamics of a rigid body sliding on a frictional contact can have multiple solutions as well as sudden contact-mode transitions. This paper is concerned with dynamic jamming, an event where a sliding rigid body suddenly jamms and experiences an impact-like transition into free flying mode. Using a simple experiment that mimics a sliding rigid-body situation, dynamic jamming is recorded for the first time. The phenomenon occurs almost at the theoretical position-and-velocity prediction, indicating that this type of jamming is not a mere artifact of the rigid-body modeling paradigm. A new interpretation of dynamic jamming is offered in terms of the body's instantaneous acceleration center. Once this center reaches a graphically determinable jamming line, the body ceases its sliding mode and experiences a dynamic jamming event. Based on this insight, some ways to prevent dynamic jamming are discussed.
Very Long-term Self-renewal of Small Intestine, Colon, and Hair Follicles from Cycling Lgr5+ve Stem Cells (2008)

The intestinal epithelium and the hair follicle represent examples of rapidly self-renewing tissue in adult mammals. We have recently identified a novel stem cell gene Lgr5 expressed in multiple adult tissues. At the bottoms of crypts in small intestine and colon as well as in hair follicles, Lgr5 marks cycling cells with stem cell properties (Barker et al. 2007; Jaks et al. 2008). Using an inducible Lgr5-Cre knockin allele in conjunction with the Rosa26-LacZ Cre reporter strain, long-term lineage-tracing experiments were performed in adult mice. The Lgr5(+ve) crypt-based cell generated all epithelial lineages during a 14-month period, implying that it represents the stem cell of the small intestine and colon. Similarly, lineage tracing during a 14-month period revealed that Lgr5(+ve) cells located in the bulge of the hair follicle sustained multiple rounds of hair growth. These observations support the counterintuitive notion that Lgr5(+ve) cells are actively cycling, yet represent long-term stem cells of these adult, self-renewing tissues.
Microbial degradation of pendimethalin (1991)

Microbial degradation of pendimethalin (N-(1-Ethylpropyl)-3, 4-dimethyl-2, 6-dinitroaniline) in vitro was studied. Fusarium oxysporum and Paecilomyces varioti, two soil fungi, in culture media degraded pendimethalin to two metabolites namely N-(1-Ethylpropyl)-3, 4-dimethyl-2-nitrobenzene-1, 6-diamine (II) and 3,4-Dimethyl-2, 6-dinitroaniline (IV). Rhizoctonia bataticola, another soil fungus, decomposed pendimethalin yielding only the latter metabolite (IV). Fungal decomposition of pendimethalin involved nitro reduction and dealkylation.
Infrastructure-based MAC in wireless mobile ad-hoc networks (2003)

In this paper, an efficient and on-the fly infrastructure is created using our proposed mobile point coordinator (MPC) protocol. Based on this protocol, we also develop an efficient MAC protocol, namely MPC-MAC. Our MAC protocol extends the IEEE 802.11 standard for use in multihop wireless ad-hoc networks implementing both the DCF and PCF modes of operation. The goal, and also the challenge, is to achieve QoS delivery and priority access for real-time traffic in ad hoc wireless environments while maintaining backward compatibility with the IEEE 802.11 standard. The performance of MPC-MAC is compared to the IEEE 802.11 DCF-based MAC without MPC. Simulation experiments show that in all cases the use of PCF benefits real-time packets by decreasing the average delay and the discard ratio. However, this may come at the expense of increasing the average delay for non-real-time data. On the other hand, the discard ratio for both real-time and non-real-time packets improves with the use of PCF. Therefore, our MPC-MAC outperforms the standard DCF IEEE 802.11 MAC protocol in multi-hop ad-hoc environments.
Smoking Relapse during the First Year after Treatment for Early-Stage Non–Small-Cell Lung Cancer (2006)

Nearly half of non-small-cell lung cancer patients return to smoking after surgery if they have recent smoking histories. Most initial lapses happen within 2 months and occur in response to more recent smoking and more intense cravings. Findings suggest that interventions to prevent relapse should target those who wait until cancer surgery to quit smoking and should be started as soon as possible after treatment.

Silicon alkoxide cross-linked silica nanoparticle gels for encapsulation of bacterial biocatalysts (2013)

A method is developed for encapsulation of bacterial biocatalysts in silica gels formed by silica nanoparticles (SNP) and a silicon alkoxide crosslinker. Formulation of the gel was optimized by changing the SNP size, SNP to crosslinker ratio and crosslinker functionality. Hydrolysis and condensation reactions of silicon alkoxide were controlled by water to alkoxide ratio (r) and pH of the solution. FTIR analysis verified that a reactive and temporally stable silicon alkoxide crosslinker was obtained. As a case study, recombinant Escherichia coli (E. coli) cells expressing the atrazine dechlorinating enzyme AtzA were encapsulated. Synthesized catalytic biomaterials (silica gel encapsulated bacterial biocatalysts) were evaluated based on their gelation time, biocatalytic activity and mechanical strength. Diffusivity assays and SEM were used for characterization of the gel structure. We found that SNP to crosslinker ratio affected all the features of the gel, whereas crosslinker functionality primarily affected the gelation time and SNP size affected the mechanical strength and diffusivity. Based on systematic evaluation, we selected three gel formulations and subjected them to long-term activity measurements in a continuous-flow bioreactor for removing trace levels of atrazine. The effluent atrazine concentration was sustained below 30% of the influent concentration, <3 ppb, for 2 months.

Anti-allergic properties ofMangifera indicaL. extract (Vimang) and contribution of its glucosylxanthone mangiferin (2006)

Vimang is the brand name of formulations containing an extract of Mangifera indica L., ethnopharmacologically used in Cuba for the treatment of some immunopathological disorders, including bronchial asthma, atopic dermatitis and other allergic diseases. However, the effects of Vimang on allergic response have not been reported until now. In this study, the effects of Vimang and mangiferin, a C-glucosylxanthone isolated from the extract, on different parameters of allergic response are reported. Vimang and mangiferin showed a significant dose-dependent inhibition of IgE production in mice and anaphylaxis reaction in rats, histamine-induced vascular permeability and the histamine release induced by compound 48/80 from rat mast cells, and of lymphocyte proliferative response as evidence of the reduction of the amount of B and T lymphocytes able to contribute to allergic response. In these experiments, ketotifen, promethazine and disodium cromoglicate were used as reference drugs. Furthermore, we demonstrated that Vimang had an effect on an in-vivo model of inflammatory allergy mediated by mast cells. These results constitute the first report of the anti-allergic properties of Vimang on allergic models, as well as suggesting that this natural extract could be successfully used in the treatment of allergic disorders. Mangiferin, the major compound of Vimang, contributes to the anti-allergic effects of the extract.

Optical fibre transmission lines (1981)

Optical fibre transmission lines have many advantages over coaxial cables. The most widely used fabrication techniques involve chemical vapour deposition resulting in losses of well below 1 dB/km. Analysis of propagation follows well-defined principles and the results obtained are broadly comparable with those at microwave frequencies, although the wavelength of operation, ̃1 μm, is much shorter. By suitable design single-mode fibres can be made to give bandwidth × length products approaching 100 GHz·km. Multimode fibres are now well understood, pose fewer problems and can be excited with light-emitting diodes.
Initial Clinical Experience With Endocardial Defibrillation Using an Implantable Cardioverter/Defibrillator With a Triple-Electrode System (1989)

We evaluated the early clinical performance of an implantable cardioverter/defibrillator with a nonepicardial lead system in patients with refractory ventricular tachycardia or ventricular fibrillation. Ten patients, mean age 67 years, mean left ventricular ejection fraction 35%, refractory to 5 +/- 2 antiarrhythmic drugs and with a history of prior cardiac surgery (7 patients), severe lung disease (2 patients), or renal failure (1 patient) underwent device and lead system implant. A tripolar electrode catheter with one sensing electrode and two defibrillating electrodes was placed in the right ventricular apex and a left thoracic submuscular patch electrode was used in an epicostal location. Defibrillation energy threshold was determined using dual- or triple-electrode configurations. Optimal patch electrode location was determined after temporary use of a cutaneous patch electrode prior to cardioverter/defibrillator implant. Electrophysiologic studies were performed before discharge and after 2 to 3 months to assess device function. Percutaneous insertion and placement of the electrode catheter was achieved in all patients. Defibrillation energy threshold testing was done using 1 to 4 (mean, 2.7) electrode configurations per patient and required 6 to 21 (mean, 13) ventricular fibrillation inductions and 8 to 56 (mean, 22) shocks per patient. In all patients, lowest reliable defibrillation energy threshold was obtained with a triple-electrode configuration (right ventricular common cathode with right atrial and thoracic patch as dual anodes) and bidirectional shocks (mean, 18 +/- 5 J). Optimal patch electrode position could be determined in 9 of 10 patients, and these 9 patients had cardioverter/defibrillator implant. Ventricular fibrillation termination with the first delivered shock at electrophysiologic study was documented in all patients. There was no perioperative mortality in device-implanted patients. Postoperative electrophysiologic studies before discharge (9 patients) and at 3 months (8 patients) continued to demonstrate successful defibrillation by the first device shock. During follow-up (range, 2 to 10 months; mean, 6 +/- 3 months), spontaneous device discharges occurred in 4 patients with inappropriate shocks due to electrode catheter fracture being documented in 1 patient. Antiarrhythmic drug therapy was withdrawn in 6 patients and reduced in 3 patients. We conclude, based on our preliminary experience, that an implantable cardioverter/defibrillator can be successfully used with a nonepicardial lead system for endocardial defibrillation in many patients. This lead system can be used with currently available pulse generators and should be considered at cardioverter/defibrillator implantation. It can be anticipated to reduce patient risk and hospital costs associated with this procedure.
Ergodic mutual information of full-duplex MIMO radios with residual self-interference (2013)

We study the theoretical performance of a full-duplex multiple-input multiple-output (MIMO) bi-directional communication system. We focus on the effect of the residual self-interference due to channel estimation errors and transmitter impairments. We assume that the instantaneous channel state information (CSI) at the transmitting nodes is not known and the CSI at the receiving nodes is imperfect. To maximize the system ergodic mutual information, which is a non-convex function of power allocation vectors at the nodes, a gradient projection (GP) algorithm is developed to optimize the power allocation vectors. This algorithm exploits both spatial and temporal freedoms of the source covariance matrices of the MIMO links between the nodes to achieve higher sum ergodic mutual information. It is observed through the simulations that the algorithm reduces to a full-duplex scheme when the nominal residual self-interference is low, or to a half-duplex scheme when the nominal residual self-interference is high.

UDRE Monitoring Analysis of Korean Satellite Navigation System (2015)

본 논문은 한국형 위성항법시스템의 위성궤도, 위성시계 고장 검출이 가능한 UDRE에 대한 모니터링 알고리즘 분석을 수행하였다. UDRE 모니터링을 위한 의사거리 잔차 생성방법 중 대류권 지연오차와 수신기 시계바이어스 추정방법에 대해 새로운 알고리즘을 제안한다. 대류권 지연오차는 국내 기상데이터에 더욱 적합한 Saastamoinen 모델과 Neill 매핑함수의 조합 모델을 사용하였으며, 수신기 시계 바이어스 추정방법으로는 칼만필터를 사용한 기법을 사용하였다. 국내 지역에서 직접 수신한 위성데이터와 기상데이터를 사용한 UDRE 모니터링 분석을 통해 한국지역에 더욱 적합한 UDRE 모니터링 한계치(Threshold)를 도출하고 추 후 한국형 위성항법시스템의 고장검출 기법으로 활용할 수 있을 것으로 기대한다.

New receiver clock bias and tropospheric delay error estimation method to make pseudo-range residual for UDRE monitoring is proposed. Saastamoinen model and Neill mapping function are used for estimate the tropospheric delay and EKF is used for estimgate the receiver clock bias. Through the satellite measurements and regional weather data received directly from the domestic is using for UDRE monitoring analysis, more suitable UDRE monitoring threshold can be deducted and it is expected to be utilized for fault detection technique of Korean Satellite Navigation System.
Conducted Noise Prediction for DC–DC Converter by Noise Source Model Accounting for Switching Fluctuation (2023)

The switching fluctuation of a dc–dc converter causes jitter and makes the conducted noise time-variant. Averaging-mode measurement with an oscilloscope or other instruments partially removes higher-frequency noise. Therefore, switching fluctuation affects the accuracy of noise prediction in using a black-box noise source model with measurement-based parameter identification. To address this issue, we proposed an approach to address the switching fluctuation effect on conducted emissions from the dc–dc converter. First, we investigate the effect of switching fluctuation by studying the difference between noise signals with and without fluctuation and estimating the reduction due to fluctuation. Then, to facilitate model parameter identification, we focus on the peak detected noise signal and improve the prediction accuracy of the peak detected noise by decomposing the measured noise signal into ripple noise and turn- <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">on</small> and turn- <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">off</small> spike noises. As a result, the peak detected noise spectrum after removing switching fluctuation can be predicted within a 3-dB error up to 200 MHz. Our experimental results show that the noise spectrum predicted by accounting for the reduction due to switching fluctuation agrees well with the spectrum obtained by averaging-mode measurement.
A point mutation in the mitochondrial DNA of diabetes-prone BHE/cdb rats. (1995)

Mitochondrial DNA was extracted from hepatic tissue of 50- and 300-day-old male BHE/cdb and Sprague-Dawley rats. The complete gene for the F0ATPase subunits 6 and 8 was sequenced. Four nucleotide substitutions were found: three of the substitutions were silent; the other substitution at position 523 was not. Its codon dictates the substitution of asparagine for aspartic acid in a critical location (in the polar pocket) of the F0ATPase. It is possible that this point mutation may explain previously reported decreases in ATP synthesis efficiency in BHE/cdb rats compared to Sprague-Dawley rats.
HARQ Feedback in Unlicensed Spectrum LTE: Design and Performance Evaluation (2017)

The uncertainty of channel availability for wireless systems in unlicensed bands necessitates new and robust designs for the feedback of uplink control information and channel state information. This work discusses the design of hybrid automatic repeat request (HARQ) feedback mechanisms and channels for unlicensed spectrum LTE. We describe in detail the motivation for new uplink physical channels that carry downlink HARQ feedback while adhering to unlicensed spectrum regulations. Finally, the performance of various control channel designs is evaluated by means of link-level simulations in order to provide insights on the trade-offs between required signal-to-noise ratio (SNR), HARQ-feedback payload size, transmission duration, and multi-user multiplexing capacity.

Block implementation of digital filters (1971)

A theory for implementation of recursive digital filters that process signals by blocks is presented. It is shown that this approach provides a very general family of filters that includes both the conventional scalar implementation and batch processing. The approach is based on a matrix representation of convolution and results in a state-variable description with block feedback. An eigenvalue analysis guarantees stability of the realization and indicates a reduction in sensitivity to roundoff and coefficient accuracy.
