FINE PATTERNING OF THERMITES FOR MECHANISTIC STUDIES AND MICROENERGETIC APPLICATIONS (2013)

Electrophoretic deposition (EPD) was combined with lithographic patterning techniques to deposit well-mixed thermites onto fine-featured (10−1000 µm) conductive substrates. It was found that thin thermite films using nano- and micronsized Al, with nanosized CuO as the oxidizer, were able to turn corners up to 150 deg with ease. Both nano- and micron-Al thermites exhibited jumping behavior, which ranged from 0 to almost 10 mm, and which increased with film thickness. This behavior is attributed to pressure buildup and unloading, which serves to rapidly advect micronscale particles at high velocity, and ahead of the reaction zone. For the quench studies, we found that very thin films (<10 µm) were needed before any quenching occurred, and even then, some systems did not quench down to 46 × 13 µm dimensions. The results of the mechanistic studies were used to examine a potential application as multichannel igniter. Delays from 6 to 18 ms were made by changing the stoichiometry, and by using both nano- and micron-Al thermites. The deposit thickness was kept above the quench value, and below the thickness corresponding to material jumping. Also, several 90 deg turns were included to reduce the overall size of the device, and to highlight the ability to include nonlinear pathways. For the deposition conditions used, it was found that the arrival time for a six-channel igniter has <5% uncertainty in timing, and <4% reproducibility between identical samples. This precision at such fine length scales is directly attributed to EPD, a low-cost and repeatable technique that allows for the deposition of energetic materials onto arbitrary fine-featured conductive substrates.

Measurement of Recombination Coefficient of Atomic Oxygen (2010)

We developed the equipment that measured the recombination coefficient of the atomic oxygen from heat balance of the temperature sensor referring to the method of measuring the recombination coefficient of the atomic hydrogen1). We added the following two improvements to the method for calculating the recombination coefficient of hydrogen1): Firstly, to suppress the influence of thermal radiation from a plasma radiation source as much as possible, we set the sensor to the position that the sensor was not exposed to the radiation from plasma directly. that the sensor Secondly, we made it possible for sensors to measure higher temperatures in some areas. The source of the oxygen radicals was microwave plasma operating at 900 W for O2 pressures of 126 Pa. The measured atomic oxygen recombination coefficients on quartz and chemically polished aluminum alloy (ALpika®) surfaces were 1.94×10−4 and 3.75×10−3, respectively.
All-Spectrum Cognitive Networking through Joint Distributed Channelization and Routing (2013)

We consider a secondary multi-hop cognitive radio network with decentralized control that operates cognitively to coexist with primary users. We propose a new spread-spectrum management paradigm, in which, unlike mainstream dynamic spectrum access research, digital waveforms are designed to occupy the entire available spectrum, and to adaptively track the interference profile at the receiver to maximize the link capacity while avoiding interference to primary users. In this context, we study the problem of maximizing the network throughput of a multi-hop network through joint routing and spread-spectrum channelization. We first propose a centralized formulation of the network control problem. We then propose an algorithm that can be seen as a distributed localized approximation of the throughput-maximizing policy. We refer to the proposed jointly-designed routing and code-division channelization algorithm as ROCH (Routing and cOde-division CHannelization). Specifically, power and spreading code are jointly selected to maximize the pre-detection secondary \mathrm{SINR} while providing quality of service guarantees to on-going primary and secondary transmissions, while the routing algorithm dynamically selects relays based on the network traffic dynamics and on the achievable data rates on different secondary links. We study the throughput and delay performance of ROCH through a extensive simulation experiments, which demonstrate the appeal of the proposed framework through significant performance gains compared to baseline solutions.
In Vivo Regulation of Alternative Pre-mRNA Splicing by the Clk1 Protein Kinase (1997)

Controlled expression of cellular and viral genes through alternative precursor messenger RNA (pre-mRNA) splicing requires serine/arginine-rich (SR) proteins. The Clk1 kinase, which phosphorylates SR proteins, is regulated through alternative splicing of the Clk1 pre-mRNA, yielding mRNAs encoding catalytically active and truncated inactive polypeptides (Clk1 and Clk1T, respectively). We present evidence that Clk1 and Clk1T proteins regulate the splicing of Clk1 and adenovirus pre-mRNAs in vivo. The peptide domain encoded by the alternatively spliced exon of Clk1 is essential for the regulatory activity of the Clk1 kinase. This is the first direct demonstration of an in vivo link between alternative splicing and protein kinase activity.
Identifying the key regulators that promote cell-cycle activity in the hearts of early neonatal pigs after myocardial injury (2020)

Mammalian cardiomyocytes exit the cell cycle shortly after birth. As a result, an occurrence of coronary occlusion-induced myocardial infarction often results in heart failure, postinfarction LV dilatation, or death, and represents one of the most significant public health morbidities worldwide. Interestingly however, the hearts of neonatal pigs have been shown to regenerate following an acute myocardial infarction (MI) occuring on postnatal day 1 (P1); a recovery period which is accompanied by an increased expression of markers for cell-cycle activity, and suggests that early postnatal myocardial regeneration may be driven in part by the MI-induced proliferation of pre-existing cardiomyocytes. In this study, we identified signaling pathways known to regulate the cell cycle, and determined of these, the pathways persistently upregulated in response to MI injury. We identified five pathways (mitogen associated protein kinase [MAPK], Hippo, cyclic [cAMP], Janus kinase/signal transducers and activators of transcription [JAK-STAT], and Ras) which were comprehensively upregulated in cardiac tissues collected on day 7 (P7) and/or P28 of the P1 injury hearts. Several of the initiating master regulators (e.g., CSF1/CSF1R, TGFB, and NPPA) and terminal effector molecules (e.g., ATF4, FOS, RELA/B, ITGB2, CCND1/2/3, PIM1, RAF1, MTOR, NKF1B) in these pathways were persistently upregulated at day 7 through day 28, suggesting there exists at least some degree of regenerative activity up to 4 weeks following MI at P1. Our observations provide a list of key regulators to be examined in future studies targeting cell-cycle activity as an avenue for myocardial regeneration.

Differential Capacities of CD4+, CD8+, and CD4−CD8− T Cell Subsets to Express IL-18 Receptor and Produce IFN-γ in Response to IL-18 (1998)

Abstract IL-12 and IL-18 have the capacity to stimulate IFN-γ production by T cells. Using a T cell clone, we reported that IL-18 responsiveness is generated only after exposure to IL-12. Here, we investigated the induction of IL-18 responsiveness in resting CD8+, CD4+, and CD4−CD8− T cells. Resting T cells respond to neither IL-12 nor IL-18. After stimulation with anti-CD3 plus anti-CD28 mAbs, CD8+, CD4+, and CD4−CD8− T cells expressed IL-12R, but not IL-18R, and produced IFN-γ in response to IL-12. Cultures of T cells with anti-CD3/anti-CD28 in the presence of rIL-12 induced IL-18R expression and IL-18-stimulated IFN-γ production, which reached higher levels than that induced by IL-12 stimulation. However, there was a substantial difference in the expression of IL-18R and IL-18-stimulated IFN-γ production among T cell subsets. CD4+ cells expressed marginal levels of IL-18R and produced small amounts of IFN-γ, whereas CD8+ cells expressed higher levels of IL-18R and produced more IFN-γ than CD4+ cells. Moreover, CD4−CD8− cells expressed levels of IL-18R comparable to those for CD8+ cells but produced IFN-γ one order higher than did CD8+ cells. These results indicate that the induction of IL-18R and IL-18 responsiveness by IL-12 represents a mechanism underlying enhanced IFN-γ production by resting T cells, but the operation of this mechanism differs depending on the T cell subset stimulated.
Intelligent Reflecting Surface Orientation Optimization to Enhance the Performance of Wireless Communications Systems (2022)

In many intelligent reflecting surface (IRS) aided communication systems, the IRS is deployed to provide a line-of-sight (LOS) link between the transmitter and receiver. In order to maximize the efficiency of the system, deploying the IRS at the correct position and orientation is important. We propose a method to find the optimal IRS orientation that maximizes the received power or achievable rate at locations within a desired geographical area. As shown through both analytical and simulation results, the proposed methodology on optimizing IRS orientation based on the receiver or transmitter locations significantly improves the overall system performance. For example, there is an approximately 8.1 bps/Hz achievable rate improvement by installing the IRS at the optimal orientation compared to an arbitrary orientation in a typical deployment scenario.
Development of a 300°C capable SiC based operational amplifier (2010)

Silicon carbide based ICs have the potential to operate at temperatures exceeding that of conventional semiconductors such as silicon. Silicon carbide (SiC) based MOSFETs and ICs were fabricated and measured at room temperature and 300°C. A common source amplifier was fabricated and tested at room temperature and high temperature. The gain at room temperature and high temperature was 7.6 and 6.8 respectively. A SiC MOSFET based operational amplifier was also fabricated and tested at room temperature and 300°C. The small signal open loop gain at 1kHz was 60 dB at room temperature and 57 dB at 300°C. Long term stability testing at 300°C of the MOSFET and common source amplifiers showed very little drift.
ADP activates protooncogene expression in renal epithelial cells (1987)

Purine nucleotides, particularly adenosine diphosphate (ADP), are the most potent mitogens known for monkey kidney epithelial cells of the BSC-1 line. To explore the molecular mechanisms by which ADP exerts its mitogenic effect, we tested the hypothesis that stimulation of DNA synthesis in these renal cells is mediated by activation of protooncogenes. Transcripts of the c-Ha-ras protooncogene were identified in quiescent, high density cells. Addition of ADP to the culture medium stimulated protooncogene expression fourfold. Maximal expression of c-ras was observed by 12 h after exposure to ADP, and preceded the initiation of DNA synthesis. Expression of the c-myc protooncogene was not detected in unstimulated cells, but accumulated maximally after 1 h of exposure to ADP. As with ADP-stimulated expression of the c-ras protooncogene, transcripts of the transferrin receptor gene reached a maximal value at 12 h, whereas the abundance of gamma-actin mRNA was not altered for up to 24 h. The results indicate that exogenous ADP stimulates protooncogene expression before initiation of DNA synthesis in renal epithelial cells in culture. These findings suggest that some physiological effects of this adenine nucleotide could be mediated by proteins specified by protooncogenes.
Immediate Mood Scaler: Tracking Symptoms of Depression and Anxiety Using a Novel Mobile Mood Scale (2017)

Collectively, these data suggest that the 12-item IMS (IMS-12) is a valid tool to assess momentary mood symptoms related to anxiety and depression. Although IMS-12 shows good correlation with standardized scales, it further captures mood fluctuations better and significantly adds to the prediction of the scales. Results are discussed in the context of providing continuous symptom quantification that may inform novel treatment options and support personalized treatment plans.

Fabrication of hierarchically structured superhydrophobic PDMS surfaces by CuO casting (2014)

Poly(dimethylsiloxane) (PDMS) is used to define channels for chemical and biological analysis due to its transparency and bio-compatibility. Rendering the channel surface superhydrophobic reduces the effective contact with the channel walls and lowers the needed pressure to push through fluids. This paper reports a novel method to fabricate superhydrophobic PDMS surfaces, with a hierarchical roughness using single-step casting of a patterned cupric oxide (CuO) mold. A structured copper surface with microscale non-communicating roughness is thermally oxidized to generate high aspect-ratio CuO whiskers. Casting PDMS films from the mold creates a micro/nanoscale hierarchical roughness, with the resulting surface exhibiting superhydrophobic characteristics (contact angle > 150° and hysteresis <;10°). With reusable large area molds fabricated in a single patterning step, this process is simpler and cheaper than alternatives based on deep reactive ion etching or laser roughening.

The effect of CFTR modulators on CT outcomes in cystic fibrosis (2019)

<b>Background:</b> There is a lack of sensitive clinical trial outcome measures to monitor the effect of novel therapies in children with cystic fibrosis (CF). <b>Aim:</b> To assess the effect of CFTR modulators on structural lung disease using computed tomography (CT) analysis methods suitable for early disease. <b>Methods:</b> CF patients receiving ivacaftor or lumacaftor-ivacaftor, and controls (age, sex, genotype matched) contributed clinical data and chest CT scans performed before and after initiation of CFTR modulator therapy. We assessed CT image biomakers from the Perth Rotterdam Annotated Grid Morphometric Analysis for CF (PRAGMA-CF), CF-CT and airway-artery dimensions. Analysis of Covariance was used to compare lung disease progression in treatment and control groups. We performed subgroup analyses on data of paediatric subjects. <b>Results:</b> We included 16 treatment and 25 control subjects, with median (range) age at baseline of 12.55 (4.25-36.49) years and 8.34 (3.47-38.29) years, respectively. Treatment subjects improved in PRAGMA-CF airways disease [-2.78(-4.44,-1.13), p=0.002] and bronchiectasis extent [-1.92(-3.01,-0.82), p=0.001] compared to controls. There were no significant differences in CF-CT outcomes or airway-artery dimensions between treatment and control groups. Subgroup analysis of paediatric data showed that PRAGMA-CF bronchiectasis [-0.93(-1.77,-0.09), p=0.032] improved in treatment subjects compared to controls. <b>Conclusion:</b> Quantitative CT image biomarkers provide more sensitive assessments of treatment efficacy on lung structure and have the potential to be used in early interventional studies. However, a larger study population is needed to determine the long-term effects of therapy on structural lung disease.

IPv6 RA-Guard (2008)

When using IPv6 within a single L2 network segment it is assumed that
for good network behavior, the available routers attached to the
segment are valid routers. A rogue Router Advertisement (RA) [1]
however could be sent by accident by a misconfigured network device,
or on purpose by malicious devices. This document proposes a solution
to reduce the threat of rogue RAs by enabling layer 2 devices to
provide forward RAs received over designated ports.

Polymyxin B Prevents Increased Sympathetic Activity and Alveolar Macrophage Tumor Necrosis Factor Release in Parenterally Fed Rats (1995)

Alveolar macrophage tumor necrosis factor production appears to be influenced by sympathetic nervous activity. Total parenteral nutrition-induced endotoxemia may indirectly alter macrophage function by stimulating sympathetic nervous activity.
Feedback-Linearizing Control of IPM Motors Considering Magnetic Saturation Effect (2005)

This paper describes feedback-linearizing control of interior permanent magnet (IPM) motors which operate in magnetic saturation. First, we propose a current tracking controller for direct control of stator currents. Then, we explicitly characterize all torque controllers that can make the motor torque of an IPM motor exactly linear with respect to torque command even if magnetic saturation occurs. In particular, our torque controller contains a free function that can be used to achieve other control objectives as well as linear dynamic characteristics. Finally, the free function is chosen so optimal as to maximize power efficiency. The practical use of our control method is demonstrated through various simulation and experimental results.
On-chip Light Trapping in Bilayer Moiré Photonic Crystal Slabs (2022)

There has been remarkable recent progress in the formation of nano-resonators that support ultra-low-loss, compact dielectric photonic crystals with exceptional high-Q modes that operate at visible or telecom wavelengths. New insights into modal engineering have recently emerged from researchers exploring exotic electronic phases in 2D materials. The phenomenon relates to a twist in the angle between two layers of materials with high periodic spatial ordering, such as graphene. A moire pattern forms, and at a particular magic angle of twist, the electronic behavior significantly changes, enjoying a flat energy-momentum dispersion relationship. There is an optical analog to the electron twistronics: bilayer moire photonic crystal slabs can realize a flat-band condition. Under these conditions, the propagating modes have zero group velocity, thus giving rise to momentum-free trapping of Bloch waves in both transverse and vertical directions, creating high quality-factors and exceptionally small modal volumes that eventually lead to the enhancement of the Purcell effect. The dramatically different means of light-localization afforded by moire-structured cavities, very small mode volumes, and spatial determination by the overall moire pattern can manipulate spontaneous emission. This provides many opportunities for applications such as low-threshold lasing, single-photon source, quantum electrodynamics, photonic circuit, and quantum information processing.
MYC overexpression imposes a nonimmunogenic phenotype on Epstein–Barr virus-infected B cells (2002)

Lymphoblastoid cell lines, generated by immortalization of normal B cells by Epstein-Barr virus (EBV) in vitro, have strong antigen-presenting capacity, are sensitive to EBV-specific cytotoxic T cells, and are highly allostimulatory in mixed lymphocyte culture. By contrast, EBV-positive Burkitt lymphoma (BL) cells are poor antigen presenters, are not recognized by EBV-specific cytotoxic T cells, and are poorly allostimulatory, which raises the question of whether immunological pressure exerted during BL pathogenesis in vivo has selected for a 'nonimmunogenic' tumor phenotype. The present work addresses this question by examining the immunogenicity/antigenicity of cell lines, generated by conversion of a conditionally immortalized lymphoblastoid cell line to permanent growth independent of EBV-latent proteins by introduction of a constitutively active or tetracycline-regulated c-myc gene (A1 and P493-6 cells, respectively). Compared with its parental lymphoblastoid cell line, A1 cells showed many of the features of the nonimmunogenic BL phenotype, namely poor allostimulatory activity, poor antigen-presenting function associated with impaired proteasomal activity, down-regulation of peptide transporter, reduced HLA class I expression, and an inability to present endogenously expressed EBV-latent proteins to cytotoxic T cells. P493-6 cells, when grown in the presence of estrogen with the exogenous c-myc gene switched off, were strongly immunogenic. The cells had lost their immunogenic potential, however, when grown on a c-myc-driven proliferation program in the absence of estrogen. Deregulation of c-myc, a step central to the development of uncontrolled BL cell growth in vivo, can thus impose a nonimmunogenic phenotype on proliferating human B cells in the absence of any immune pressure.

9 kV, 1 cm<sup>2</sup> SiC Gate Turn-Off Thyristors (2010)

In this paper, for the first time, we report a large area (1 cm2) SiC GTO with 9 kV blocking voltage fabricated on 100-mm 4H-SiC substrates with much reduced Basal Plane Dislocation (BPD) density. The static and dynamic characteristics are described. A forward drop of 3.7 V at 100 A (100 A/cm2) is measured at 25°C. A slight positive temperature coefficient of the forward drop is present at 300 A/cm2, indicating the possibility of paralleling multiple devices for higher current capability. The device exhibits extremely low leakage currents at high temperatures. The device has shown fast turn-on time of 53.9 nsec, and ~3.5 s of turn-off time, respectively. A stable forward voltage drop after electrical stress for &gt;1000 hours has been achieved.
