Daylength and Circadian Effects on Starch Degradation and Maltose Metabolism (2005)

Transitory starch is stored during the day inside chloroplasts and broken down at night for export. Maltose is the primary form of carbon export from chloroplasts at night. We investigated the influence of daylength and circadian rhythms on starch degradation and maltose metabolism. Starch breakdown was faster in plants of Arabidopsis (Arabidopsis thaliana) ecotype Wassilewskija growing in long days. Transcript levels of genes encoding enzymes involved in starch degradation and maltose metabolism showed a strong diurnal rhythm. Under altered photoperiods, the transcript levels and the rate of starch degradation changed within one day/night cycle. However, the amount of proteins involved in starch degradation was maintained relatively constant throughout the day/night cycle. To investigate whether the diurnal cycling of the transcript levels is only a response to light or is also regulated by a circadian clock, we measured the amount of messenger RNAs in Arabidopsis leaves under continuous light and continuous darkness. The expression of genes encoding starch degradation-related enzymes was under very strong circadian control in continuous light. Under continuous light, the amount of maltose also showed a strong endogenous rhythm close to 24 h, indicating that maltose metabolism is under circadian control. Light is necessary for the cycling of transcript levels and maltose levels. Under continuous darkness, these genes were barely expressed, and no cycling of maltose levels was observed.

Refined statistical static timing analysis through learning spatial delay correlations (2006)

Statistical static timing analysis (SSTA) has been a popular research topic in recent years. A fundamental issue with applying SSTA in practice today is the lack of reliable and efficient statistical timing models (STM). Among many types of parameters required to be carefully modeled in an STM, spatial delay correlations are recognized as having significant impact on SSTA results. In this work, we assume that exact modeling of spatial delay correlations is quite difficult, and propose an experimental methodology to resolve this issue. The modeling accuracy requirement is relaxed by allowing SSTA to impose upper bounds and lower bounds on the delay correlations. These bounds can then be refined through learning the actual delay correlations from path delay testing on silicon. We utilize SSTA as the platform for learning and propose a Bayesian approach for learning spatial delay correlations. The effectiveness of the proposed methodology is illustrated through experiments on benchmark circuits
First-order transition to a metallic state in polyacetylene: A strong-coupling polaronic metal (1985)

We present a theory of the first-order transition to the metallic state in polyacetylene in terms of a crossover from a lattice of charged solitons to a regular array of polaronlike distortions. The polaronic metal is shown to have a strong indirect attractive interaction, ${\mathrm{U}}^{\mathrm{*}}$\ensuremath{\simeq}-2\ensuremath{\Delta}/3, between electrons in the half-filled, narrow, polaron subband within the Peierls energy gap (${\mathrm{E}}_{\mathrm{g}}$=2\ensuremath{\Delta}).
<title>Fourier Transform Image Tracker And Stabilizer</title> (1981)

Fourier transform techniques have been applied to measure image velocity and position. These patented techniques have been incorporated into airborne image motion compensation sensors, helicopter-borne image stabilizers, and TV trackers for tank and helicopter fire control. Microradian tracking accuracy at less than 5-percent contrast has been demonstrated with simpler and less costly hardware than required with correlation techniques.
A FLEXIBLE DISTAL TIP WITH TWO DEGREES OF FREEDOM FOR ENHANCED DEXTERITY IN ENDOSCOPIC ROBOT SURGERY (2015)

A flexible distal tip with two degrees of freedom has been developed for endoscopic robot surgery. The flexible tip consists of a superelastic NiTi tube which can be bent from-90º to +90º in 2 directions by means of 4 cables. The improvement over previous devices is the combination of two degrees of freedom with a small diameter of only 5 mm. An additional advantage is the tool channel which enables the use of different instruments with this single device.

Adaptive Rate Control Mechanism in H.264/AVC for Scene Changes (2014)

Rate control that is required to regulate the bitrate of video coding is critical to time-sensitive video applications used over networks. However, the H.264/AVC standard does not respond to scene changes, and this causes the transmission quality to deteriorate as a scene change occurs. In this work, a scene change is detected by comparing the ratio of the sum of absolute difference (SAD) between two consecutive frames. As the scene change is detected, the proposed method, which is modified from the reference software of H.264/AVC, re-assigns a quantization parameter (QP) value to regulate the bitrate. Because the inter-prediction works poorly for the scene-changed frame, the proposed method estimates its frame complexity based on the content, and further creates another Q-R model to assign QP. The adaptive rate control mechanism presented in this study can quickly respond to the heavy bitrate increment caused by a change of scene. Simulation results show that the proposed method improves the average peak signal noise ratio (PSNR) to approximately 1.1dB, with a smaller buffer size compared with the performance of the reference software JM version 17.2.
Construction and Modeling of Concatemeric DNA Multilayers on a Planar Surface as Monitored by QCM-D and SPR (2014)

The sequential hybridization of a 534 base pair DNA concatemer layer was monitored by QCM-D and SPR, and the QCM-D data were analyzed by Voigt viscoelastic models. The results show that Voigt-based modeling gives a good description of the experimental data but only if shear viscosity and elasticity are allowed to depend on the shear frequency. The derived layer thickness, shear viscosity and elasticity of the growing film give a representation of the DNA film in agreement with known bulk properties of DNA, and reveal a maximum in film viscosity when the molecules in the layer contain 75 base pairs. The experimental data during construction of a 3084 bp DNA concatemer layer were compared to predictions of the QCM-D response of a 1 μm thick film of rod-like polymers. A predicted nonmonotonous variation of dissipation with frequency (added mass) is in qualitative agreement with the experiments, but with a quantitative disagreement which likely reflects that the flexibility of such long DNA molecules is not included in the model.
FEAR [Free Experimentation Aids Revelation] (2011)

Traditionally the design and production of motion graphics and animation is a slow, quiet process. The aim of this project, from the perspective of the student participant, is to show the interrelationship between sound and visuals, and how they can tap into a more spontaneous form of creativity by designing visual work interactively in real-time. This project gives the student freedom to produce visual work live as they produce sounds and react to music, and other environmental stimuli. The aim of the project, from a pedagogic perspective, is to consider how students drive their own creative development through an independent and collaborative approach to learning.
Fabrication of High Power Deep Ultraviolet Light-Emitting Diodes with Glass Lenses Using Atomic Diffusion Bonding (2019)

This work demonstrated that both the output power and external quantum efficiency of AlGaN-based deep ultraviolet light-emitting diodes (DUV-LEDs) are greatly enhanced by bonding glass lenses to the LED chips using atomic diffusion bonding (ADB). ADB is advantageous because it permits the bonding of glass to DUV-LEDs at room temperature. A Ti film was found to improve light transmittance through the bonding interface and to provide good bonding strength. In addition, hydrophilic treatment of the bonding surfaces prior to Ti film deposition during ADB and post-bonding annealing further enhanced the bonding strength. In this manner, 255 nm DUV-LEDs with glass lenses having n values almost equal to that of sapphire were fabricated, using the ADB process in conjunction with a 0.4-nm-thick Ti film on each side. Even though the glass lens exhibited some light absorption, the output power and the maximum external quantum efficiency of these glass-lens-bonded LEDs were both 2.5 times greater than the values for an LED without a lens.
Decrease in Plasma B-Type Natriuretic Peptide Early After Initiation of Cardiac Resynchronization Therapy Predicts Clinical Improvement at 12 Months (2006)

Percentage change in plasma BNP levels from baseline to 3 months was the strongest predictor of long-term response to CRT and may have potential to predict outcome.
Course of feline leukemia virus infection and its detection by enzyme-linked immunosorbent assay and monoclonal antibodies (1983)

Monoclonal antibodies specific for 3 distinct epitopes of the species-specific determinants of feline leukemia virus (FeLV) p27 were used in an enzyme-linked immunosorbent assay (ELISA) for measurement of serum p27 in cats infected with FeLV. Group-specific antigen (GSA) of FeLV in peripheral blood leukocytes was also determined by an immunofluorescence assay. Antibodies to FeLV and the feline oncornavirus-associated cell membrane antigen (FOCMA) were also measured. Thirty-six cats were surveyed and assigned to 4 categories. Five developed persistent viremia (category 1), characterized by continuous expression of p27, GSA, and low antibody titers to FeLV and FOCMA. Eleven cats with transient viremia (category 2) and 13 cats that were never detectably viremic (category 3), as judged by absence of GSA and p27, developed increased antibody titers to FeLV and FOCMA. Seven cats were never viremic, as judged by the GSA in the peripheral blood leukocytes, but still had detectable serum p27 (category 4). Most category 4 cats developed high antibody titers against FOCMA and/or FeLV. Of 307 field cats examined, 7% of the healthy cats and 10% of the sick cats could be assigned to category 4. However, this difference was not significant (P greater than or equal to 0.05). Of 26 cats with neoplasms 2 (1 of 12 with lymphosarcoma) could be classified as category 4. Because virus could be isolated from 2 category 4 cats, they were considered immune carriers.
Ovicidal Activity of Organophosphate, Oxadiazine, Neonicotinoid and Insect Growth Regulator Chemistries on Northern Strain Plum Curculio,Conotrachelus nenuphar (2008)

An in vitro method was developed for assessing ovicidal effects of the organophosphate azinphos-methyl, the neonicotioids thiacloprid, thiamethoxam and clothianidin, the oxadiazine indoxacarb and the insect growth regulators novaluron and pyriproxifen on the plum curculio, Conotrachelus nenuphar (Herbst)(Coleoptera: Curculionidae). The baseline survivorship of this method was 88 percent. Plum curculio eggs were most sensitive to azinphos-methyl. Thiacloprid, clothianidin and the chitin synthesis inhibitor, novaluron, had LC50 values below 100 ppm. Thiamethoxam, indoxacarb and pyriproxifen were not ovicidal at 100 ppm. Octanol-water partitioning coefficients, log Kow, appeared to be an important indicator of ovicidal activity within the neonicotinoids. This new bioassay method eliminates the confounding of the insect-chemical and plant-chemical interactions and the results highlight the utility of a post-infestation curative approach to plum curculio management.
Acceleration Factors for Thin Gate Oxide Stressing (1985)

Time dependent dielectric breakdown (TDDB) data for 100Å of thermally grown SiO2 has been analyzed using an Eyring model based on thermodynamic free energy considerations. The model describes well the following features of the data: (1) an apparent activation energy which is a function of the stressing electric field and (2) a field acceleration parameter that is a function of temperature. Quantitatively, the model suggests the proper field dependence for the activation energy and the observed temperature dependence of the field acceleration in the 100Å oxide material. The apparent activation energy is found to decrease from > leV at low field stressing (Eb(50%) - Es > 5 MV/cm) to <0.3eV at higher fields Eb(50%)- Es < 3 MV/cm). Also, the field acceleration was found to be approximately 6 decades/MV/cm at room temperature but reduces to 2 decades/MV/cm at 150C.
TAPE (2005)

Transactional Coherence and Consistency (TCC) provides a new parallel programming model that uses transactions as the basic unit of parallel work and communication. TCC simplifies the development of correct parallel code because hardware provides transaction atomicity and ordering. Nevertheless, the programmer or a dynamic compiler must still optimize the parallel code for performance.This paper presents TAPE, a hardware and software infrastructure for profiling in TCC systems. TAPE extends the hardware for transactional execution to identify performance impediments such as dependence violations, buffer overflows, and work imbalance. It filters infrequent events to reduce resource requirements and allows the programmer to focus on the most important bottlenecks. We demonstrate that TAPE introduces minimal die area and performance overhead and can be used continuously, even for production runs. Moreover, we demonstrate how to leverage the profiling information to guide optimization for a set of parallel applications. TAPE accurately identifies the source code location and type of the most important bottlenecks, allowing a programmer to achieve maximum parallel speedup with a few profiling steps.
Studies on the Mode of Action of Soybean Lecithin. Part 3. Effects on the Infection Process of Rice Blast Fungus, Pyricularia oryzae. (1992)

To clarify the mode of action of soybean lecithin (SL), we studied the effect on morphology of Pyricularia oryzae by using the onion epidermal strip method. SL at 500ppm induced an abnormal structure at the surface of the conidium or the germ tube. From observation 24hr after inoculation. SL did not inhibit appressorial formation at 5ppm, but 500ppm or more SL inhibited 86.2% or more appressorial formation. 500ppm SL also induced a morphological abnormality in germ tube with its branching at the tip and consequently inhibited appressorial formation. Besides, SL inhibited 96% appressorial penetration at 5ppm. The inhibition of appressorial penetration is the most characteristic action of SL.
Report of the Electrodynamic Interactions Panel (1985)

A wide range of opportunities is provided by the electrodynamic tether to more fully understand the generation of waves in plasmas, the behavior of field aligned currents, the behavior of large body-space plasma interactions, and for process simulation, using the electrodynamic tether to study processes and phenomena relevant to solar system and astrophysics plasma physics. The electrodynamic tether offers a means of study and experimentation in space which will provide a rich yield in new scientific results and will enhance the understanding of space plasma physics. It also has promising technological applications (e.g., the generation of electrical power and thrust) which may be highly significant to future space operations.

Apoptosis in human breast and gastrointestinal carcinomas. Detection in histological sections with monoclonal antibody to single-stranded DNA. (1996)

We report application of a novel immunohistochemical procedure for the staining of apoptotic (AP) cells in paraffin sections using monoclonal antibody (MAb) to single-stranded DNA. MAb differentiated between apoptosis and necrosis and in contrast to in situ end labelling specifically stained only AP cells. AP carcinoma cells stained with the antibody were detected in 32 of 58 infiltrating human breast carcinomas and in 9 of 15 colon adenocarcinomas. Stromal cells stained with the MAb were observed in all carcinomas, including those in which no AP carcinoma cells were detected. There was a strong positive correlation between the presence of AP cells, loss of hormone receptors and a high proliferation rate in breast carcinomas. AP cells were present in 80-87% of receptor-negative carcinomas, while most of receptor-positive breast carcinomas did not contain AP cells. Apoptosis in tumor cells was detected significantly more frequently among breast carcinomas with high, than among carcinomas with low S-phase fraction. AP cells were present in 93-95% of breast carcinomas which were receptor-negative and had a high S-phase fraction. Immunostaining demonstrated a strong positive correlation between the loss of bcl-2 protein and intensive apoptosis in breast carcinomas. Association between apoptosis and markers of poor prognosis in breast cancer (loss of hormone receptors, intensive proliferation, loss of bcl-2 protein) indicates that apoptotic cell death is typical of more aggressive carcinomas.
Complementary Use of Electrochemistry and Synthetic Redox Chemistry in the Oxidation of Decamethylferrocene: An Integrated Advanced Laboratory Experiment (2018)

An integrated pair of experiments has been developed to introduce undergraduate students to the ways in which electrochemistry can complement conventional synthetic chemistry involving redox reactions. Students first use cyclic voltammetry and linear scan voltammetry to characterize and quantify the products of the reaction between decamethylferrocene and the 4-nitrophenyldiazonium ion. In the following lab period, they synthesize the decamethylferrocenium ion as its tetrafluoroborate salt.
NLOS channel identification and mitigation in Ultra Wideband ToA-based Wireless Sensor Networks (2009)

Recently, Ultra Wideband (UWB) Time of Arrival (ToA)-based localization in Wireless Sensor Networks (WSNs) have received considerable attention. For a typical WSN operating in indoor environments, the localization performance can be degraded considerably due to the existence of non-line-of-sight (NLOS) channel conditions between the sensor nodes. In these channel conditions the ranging accuracy is degraded due to the attenuation and/or loss of the Direct Path (DP) signal which ultimately imposes a positive bias on the ToA-based distance estimation. As a result there is a need for robust algorithms that have the capability to identify and mitigate those NLOS ranging conditions. In this paper, we propose a novel, low complexity wireless channel condition estimation algorithm that identifies the condition of the channel. Based on the estimated ToA and Received Signal Strength (RSS) the algorithm identifies the channel condition which can be either LOS, NLOS - DP available, or NLOS - DP not available. A channel measurement campaign was conducted in an office environment and the measurement results confirms the validity of our algorithm. To integrate our channel condition estimation into the localization schemes, we propose two weight assignment schemes which generate either a “soft weight” or a “hard weight”. Simulation results show that our estimator has robust performance with success rate of 85%. The simulations also show that by taking advantage of the channel condition estimation, we are able to reduce the RMSE of the localization estimate by over 40%.
Peptide purification using the chemoselective reaction between N‐(methoxy)glycine and isothiocyanato‐functionalized resin (2016)

An efficient peptide purification strategy is established, comprising the selective reaction of an N-terminal N-(methoxy)glycine residue of the peptide and isothiocyanato-functionalized resins, and subsequent Edman degradation. These reactions take place in acidic media; in particular, the Edman degradation proceeds smoothly in media containing more than 50% trifluoroacetic acid (v/v). These acidic conditions offer increased solubility, making them advantageous for the purification of hydrophobic and aggregation-prone peptides. The effectiveness of this method, together with scope and limitations, is demonstrated using model peptides and the practical purification of the loop region of the human dopamine D2 receptor long isoform (residues 240-272).
