Effect of plant moisture stress and application surface on uptake and translocation of triclopyr with organosilicone surfactant in red maple seedlings (1995)

This study investigated the effect of plant moisture stress and surface of application on the absorption, translocation, and "rainfastness" (short-term ability to retain herbicide) of organosilicone-adjuvated (adjuvant added) [ 14 C]triclopyr amine on greenhouse-grown, 4-month-old red maple (Acerrubrum L.) seedlings. Xylem water potentials were −1.6 and −0.9 MPa and leaf conductances were 0.07 and 0.13 cm s −1 for the stressed and control seedlings, respectively. At 2 h, rainfastness was 13% less for stressed seedlings. Uptake increased with time, and by 72 h no effect of moisture stress treatment was apparent. Abaxial absorption into living leaf tissue was 57% greater at 72 h than was adaxial absorption, but application surface did not significantly affect translocation. Plant moisture stress did, however, reduce translocation of herbicide into the shoots and roots. Organosilicone surfactants may enhance long-term triclopyr uptake in water-stressed seedlings, but do not appear to facilitate translocation in stressed seedlings. Plant moisture status, therefore, should continue to be a concern when scheduling herbicide applications.
The influence of light propagation direction on the stress-induced polarization dependence of silicon waveguides (2006)

This letter studies the effects of light propagation direction on the stress-induced polarization dependence of silicon-based waveguides. Silicon is an anisotropic material, so the stresses and the corresponding change of polarization dependence vary with the light propagation directions. The analyses show that when the light propagates in lang010rang directions on (100) silicon, the stress-induced changes of refractive index and the birefringence in effective index are about 20% more sensitive to the stresses than those when the light propagates in lang011rang directions
A new fluorescent and colorimetric sensor for hydrazine and its application in biological systems (2014)

Hydrazine is a very important industrial chemical and exhibits high toxicity to human beings. Here we have constructed a novel ICT-based fluorescence sensor with a high selectivity and sensitivity, rapid detection, and huge color-change. We used the sensor for hydrazine determination in live cells and also in live fish, and manufactured dipsticks using our sensor. The sensing mechanism is well rationalized with the aid of TD-DFT (time-dependent density functional theory) calculations.
Nuclear Endosperm Development in Cereals and Arabidopsis thaliana (2004)

Introducing SSDs to the Hadoop MapReduce Framework (2014)

Solid State Drive (SSD) cost-per-bit continues to decrease. Consequently, system architects increasingly consider replacing Hard Disk Drives (HDDs) with SSDs to accelerate Hadoop MapReduce processing. When attempting this, system architects usually realize that SSD characteristics and today's Hadoop framework exhibit mismatches that impede indiscriminate SSD integration. Hence, cost-effective SSD utilization has proved challenging within many Hadoop environments. This paper compares SSD performance to HDD performance within a Hadoop MapReduce framework. It identifies extensible best practices that can exploit SSD benefits within Hadoop frameworks when combined with high network bandwidth and increased parallel storage access. Terasort benchmark results demonstrate that SSDs presently deliver significant cost-effectiveness when they store intermediate Hadoop data, leaving HDDs to store Hadoop Distributed File System (HDFS) source data.

Importance of Age of Host in Detecting Tumor-Associated Transplantation Antigens (1974)

Abstract We report here the importance of the age of the host in the detection of immunogenic tumor-specific transplantation antigens (TSTA)3 in transplantation experiments in vivo. Demonstration of the presence of TSTA on the K-BALB cell line, a BALB/3T3 cell line transformed by the Kirsten strain of murine sarcoma virus (MSV) but not producing virus, was dependent on the age of the BALB/c mice immunized. Stephenson and Aaronson (1) previously failed to detect tumor-associated transplantation antigens (TATA) on this same cell line when they performed transplantation immunity studies in 6- to 8-week-old BALB/c mice. Their negative conclusion was based, in part, upon observing comparable protection when using K-BALB and the parental BALB cell lines as vaccines. The authors admitted that the BALB/3T3 parental cell line may have undergone antigenic changes concomitant with prolonged passage in vitro Furthermore, we (unpublished observation) and others (2) have found that the putative normal BALB/3T3 cell line is, in fact, weakly tumorigenic.
A 3D coil structure achieving uniform magnetic field for in-vitro cell experiments (2017)

Extremely high levels of magnetic fields can be generated by Wireless Power Transfer (WPT) systems for E-vehicles. There is a concern on the impact of human exposure to electromagnetic fields of WPT especially on any cell responses related to potential hazards. In this paper, a novel 3D coil winding structure is proposed to achieve an extremely uniform magnetic field inside the solenoid required for in-vitro experiments in analyzing cellular changes under radiation induced by WPT systems. The uniformity requirement of the magnetic field inside the 3D coil is confirmed by numerical simulations using HFSS software and by experiments.

Phenolic Yellowing of Textiles during Storage. Part 1 ‐ Occurrence, Characterisation and Causes (1983)

A commonly occurring type of yellowing is described that typically takes the form of bright yellow patches or bands on the folded edges of nylon garments stored for long periods in cardboard boxes; it can also occur on other substrates and in other modes of storage not associated with cardboard. It can be distinguished from other types of yellowing by chemical and physical tests and is shown to be caused by the interaction of atmospheric nitrogen oxides with certain phenolic substances present in, for example, storage materials. The resulting compounds, which are almost certainly nitrated phenols, are colourless in acid media but yellow in alkaline; they can sublime in the acid form and migrate at room temperature through protective plastic films, to be fixed in the yellow, alkaline form on nylon fabric., or on other substrates contaminated by alkaline residues. In unbleached cardboard the phenolic precursors appear to be decomposition products of lignin. In the absence of cardboard the yellowing is attributed to other substituted phenols such as antioxidants that may have been added deliberately, or may be present as residual traces in, for example, dyed fabrics. The most likely source of nitrogen oxides is exhaust fumes from motor vehicles. Methods of preventing this type of yellowing are outlined.
Combining Word and Character Vector Representation on Neural Machine Translation (2019)

This paper describes combinations of word vector representation and character vector representation in English-Indonesian neural machine translation (NMT). Six configurations of NMT models were built with different input vector representations: word-based, combination of word and character representation using bidirectional LSTM (bi-LSTM), combination of word and character representation using CNN, combination of word and character representation by combining bi-LSTM and CNN by three different vector operations: addition, pointwise multiplication, and averaging. The experiment results showed that NMT models with concatenation of word and character representation obtained BLEU score higher than baseline model, ranging from 9.14 points to 11.65 points, for all models that combining both word and character representation, except the model that combining word and character representation using both bi-LSTM and CNN by addition operation. The highest BLEU score achieved was 42.48 compared to the 30.83 of the baseline model.

An automatic fault tracking approach based on ant colony algorithm (2012)

The mapping of the fault network is of key importance in reservoir characterization. Interpretation of faults in seismic data is today most commonly a manual task. This is time consuming and difficult to do accurately. Automatic extraction of the fault surfaces would allow user-interaction at a higher level. In this paper, we implemented and tested an automatic fault tracking scheme based on ant colony algorithm. We applied the proposed method to auto-track the fault on seismic data. Its performance on real seismic data indicates that the proposed method can effectively reduce the noise level and improve the continuity of faults on seismic coherency cube. In order to assess the performance of the auto-tracking for faults, we make a comparison of the results from the auto-tracking with manual interpretations of fault geometry over the same area. The comparison demonstrates that the proposed method detects most faults accurately.
Innovative Safety Concept to Shutdown Short Circuit Currents in Battery Systems up to 1000V Based on Ultrafast Pyrofuse Technology (2018)

The battery of electric and hybrid vehicles with a power density of several 100KW / kg must be galvanically separated from the rest of the electrical system in case of thermal overload or a short circuit, as it may occur in an accident. In existing protecting circuits melting fuses and mechanical circuit breakers have been the choice for over current protection. Challenging new applications, have brought conventional current breaking devices to their limits. Mechanical circuit breakers and fuses are too slow to open fault currents in new high power Li-Ion battery packs. The triggering speed of a fuse depends on the current intensity and therefore the time to complete electrical isolation is undefined and not acceptable to keep the high safety standards in automotive environments. In this paper we show the newest development of fuses with pyrotechnic separating elements, so called “powerfuses”. Powerfuses are active controllable via current pulse and can switch off currents of 20 kiloamps and 1000VDC in the range of milliseconds. Various combinations of powerfuse and high volt DC relays are studied and the results are discussed.
Theoretical Models of Microvascular Oxygen Transport to Tissue (2008)

To improve understanding of microvascular O(2) transport, theoretical modeling has been pursued for many years. The large number of studies in this area attests to the complexities (i.e., biochemical, structural, and hemodynamic) involved. This article focuses on theoretical studies from the last two decades and, in particular, on models of O(2) transport to tissue by discrete microvessels. A brief discussion of intravascular O(2) transport is first given, highlighting the physiological importance of intravascular resistance to blood-tissue O(2) transfer. This is followed by a description of the Krogh tissue cylinder model of O(2) transport by a single capillary, which is shown to remain relevant in modified forms that relax many of the original biophysical assumptions. However, there are many geometric and hemodynamic complexities that require the consideration of microvascular arrays and networks. Multivessel models are discussed that have shown the physiological importance of heterogeneities in vessel spacing, O(2) supply, red blood cell flow path, as well as interactions between capillaries and arterioles. These realistic models require sophisticated methods for solving the governing partial differential equations, and a range of solution techniques are described. Finally, the issue of experimental validation of microvascular O(2) delivery models is discussed, and new directions in O(2) transport modeling are outlined.
Relief of a repressed gene expression state in the mouse 1-cell embryo requires DNA replication (1998)

In the mouse, transcriptional permissiveness is established in the fertilized egg prior to the activation of zygotic genes at the 2-cell stage. Therefore, gene inactivity initiated at the end of gametogenesis results from a complex process, involving more than an inhibition of the basal transcriptional apparatus. We have examined the ability of the first intron (I1) of the human hypoxanthine phosphoribosyl transferase gene, which functions as an enhancer in embryonic stem cells, to activate a reporter gene when placed proximally to or at a distance from the HSV-tk promoter, or when integrated into the mouse genome as part of a stable transgene. In microinjected embryos, I1 functions as an enhancer sequence; however, its competence for long-range activation appears only after the late 1-cell stage and depends on the first DNA replication. Moreover, activation of microinjected transgenes from proximal enhancers occurs in the late 2-cell embryo and in the male pronucleus of 1-cell embryos blocked for DNA replication; whereas, for integrated transgenes, proximal enhancer activity is subject to position effects in the 2-cell embryo and first occurs at the 2- or 4-cell stage, but only after completion of DNA replication. Therefore, the absence of long-range activation and a non-permissive genomic state (the relief of which both depend on DNA replication), together with an inactive transcriptional apparatus, appear to converge to prevent any gene activity in the 1-cell embryo. We propose that the embryo exploits the process of DNA replication to relieve the transcriptionally repressive state that was initially established to fulfil two purposes: (1) to arrest maternal gene expression in the maturing oocyte and (2) to protect the unicellular egg and 1-cell embryo from premature differentiation. Reactivation of gene expression by DNA replication would therefore serve to coordinate cell proliferation and differentiation in the preimplantation embryo.

Induction of alpha/beta interferon and dependent nitric oxide synthesis during Chlamydia trachomatis infection of McCoy cells in the absence of exogenous cytokine (1996)

The propensity of two Chlamydia trachomatis strains (L2/434/Bu [biovar LGV] and E/DK20/ON [biovar trachoma]) to induce putative host defense responses upon infection of McCoy (mouse) cell cultures was examined. Both strains induced production of alpha/beta interferon and nitric oxide (NO) by McCoy cells. NO synthesis was mediated by the inducible isoform of NO synthase as indicated by the ability of cycloheximide or the arginine analog NG-monomethyl-L-arginine to abolish NO production; the extent of the response was dependent upon the dose of chlamydiae applied. Incubation of McCoy cells with chloramphenicol prior to infection reduced NO production by strain 434 but not by DK20, suggesting that initial chlamydial metabolism was essential to induction by the LGV strain. Antibody inhibition studies indicated that NO synthesis was dependent upon production of alpha/beta interferon and induction via lipopolysaccharide. Overall, our findings show that chlamydiae are capable of the induction of interferon and NO in murine fibroblasts in the absence of exogenous cytokines. However, the role of NO as an antichlamydial effector could not be clearly demonstrated since treatment with an arginine analog, while suppressing NO production, gave no consistent enhancement of infected cell numbers.
Metabolic profiling of cancer cells reveals genome-wide crosstalk between transcriptional regulators and metabolism (2019)

Transcriptional reprogramming of cellular metabolism is a hallmark of cancer. However, systematic approaches to study the role of transcriptional regulators (TRs) in mediating cancer metabolic rewiring are missing. Here, we chart a genome-scale map of TR-metabolite associations in human cells using a combined computational-experimental framework for large-scale metabolic profiling of adherent cell lines. By integrating intracellular metabolic profiles of 54 cancer cell lines with transcriptomic and proteomic data, we unraveled a large space of associations between TRs and metabolic pathways. We found a global regulatory signature coordinating glucose- and one-carbon metabolism, suggesting that regulation of carbon metabolism in cancer may be more diverse and flexible than previously appreciated. Here, we demonstrate how this TR-metabolite map can serve as a resource to predict TRs potentially responsible for metabolic transformation in patient-derived tumor samples, opening new opportunities in understanding disease etiology, selecting therapeutic treatments and in designing modulators of cancer-related TRs.
Managing code ownership (2003)

Solving the problem of failed project ownership is not merely a process of assigning developers to subsystems. This article describes four code ownership models, ranging from one individual owning an entire system to the collective ownership that is a core extreme programming practice. No single code ownership model is best. In fact, many projects would benefit from dynamically adjusting the ownership model over time as development progresses through, for example, the four phases of the unified process.
