Rate-Optimal Streaming Codes for Channels with Burst and Isolated Erasures (2018)

Recovery of data packets from packet erasures in a timely manner is critical for many streaming applications. An early paper by Martinian and Sundberg introduced a framework for streaming codes and designed rate-optimal codes that permit delay-constrained recovery from an erasure burst of length up to B. A recent work by Badr et al. extended this result and introduced a sliding-window channel model C(N, B, W). Under this model, in a sliding-window of width W, one of the following erasure patterns are possible (i) a burst of length at most B or (ii) at most N (possibly non-contiguous) arbitrary erasures. Badr et al. obtained a rate upper bound for streaming codes that can recover with a time delay T, from any erasure patterns permissible under the C(N, B, W) model. However, constructions matching the bound were absent, except for a few parameter sets. In this paper, we present a family of codes that achieves the rate upper bound for all feasible parameters N, B, W and T.
A Pyrazine-Bridged Ni(II) Coordination Polymer (2002)

The single pyrazine-bridged polymeric complex {[Ni(pyz)(H 2 O) 4 ](NO 3 ) 2 .2H 2 O}n has been synthesised and characterised by elemental analyses, IR and UV-vis spectra, and a single-crystal X-ray diffraction study. The coordination around the Ni centre is perfectly octahedral. The Ni(H 2 O) 4 coordination planes are bridged by pyrazine ligands forming an infinite chain structure. Two nitrate anions and two water molecules exist in the lattice and are linked by intermolecular hydrogen bonds to the coordinated water molecules.
Disruption of the Rbm38-eIF4E Complex with a Synthetic Peptide Pep8 Increases p53 Expression (2018)

Rbm38 is a p53 target and an RNA-binding protein known to suppress p53 translation by preventing eukaryotic translation initiation factor 4E (eIF4E) from binding to p53 mRNA. In this study, we show that synthetic peptides corresponding to the binding interface between Rbm38 and eIF4E, including an 8 amino acid peptide (Pep8) derived from Rbm38, are effective in relieving Rbm38-mediated repression of p53. Molecular simulations showed that Ser-6 in Pep8 forms a hydrogen bond with Asp-202 in eIF4E. Substitution of Ser-6 with Lys, but not with Asp, enhanced the ability of Pep8 to inhibit the Rbm38-eIF4E complex. Importantly, Pep8 alone or together with a low dose of doxorubicin potently induced p53 expression and suppressed colony and tumor sphere formation and xenograft tumors in Rbm38- and p53-dependent manners. Together, we conclude that modulating the Rbm38-eIF4E complex may be explored as a therapeutic strategy for cancers that carry wild-type p53. SIGNIFICANCE: Disruption of the Rbm38-eIF4E complex via synthetic peptides induces wild-type p53 expression, suppresses tumor growth and progression, and may serve as a novel cancer therapeutic strategy.

MEMS-compatible high-density trench capacitor with ultra-conformal Cu/SiO (2011)

We have successfully fabricated a 3D super-capacitor, which can be integrated with MEMS in a wafer level, using Si trenches (aspect ratio = 53) and ultra-conformal supercritical fluid deposition (SCFD) of Cu/SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> layers. Taking advantage of large inner surface area of the trenches, the 3D capacitor exhibited 70 times larger capacitance than a planar one having the same projected area, and low leakage current density (<;3.8×10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-5</sup> A/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) at an electric field of 1.5-2.4 MV/cm. This achievement is brought about by ultra-conformal and void-free coating of a SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> layer, having a dielectric constant equivalent to the film by conventional deposition method, and ultra-conformal deposition of Cu on oxide surface, both of which are significant achievements for SCFD. Metal-insulator-metal structure is also feasible using a similar process technology, which will allow us monolithic integration of a power storage element, a power generator and sensors in a single MEMS chip for the purpose of battery-free sensor nodes in sensor network.
Internet browsing and searching: User evaluations of category map and concept space techniques (1998)

The Internet provides an exceptional testbed for developing algorithms that can improve browsing and searching large information spaces. Browsing and searching tasks are susceptible to problems of information overload and vocabulary differences. Much of the current research is aimed at the development and refinement of algorithms to improve browsing and searching by addressing these problems. Our research was focused on discovering whether two of the algorithms our research group has developed, a Kohonen algorithm category map for browsing, and an automatically generated concept space algorithm for searching, can help improve browsing and/or searching the Internet. Our results indicate that a Kohonen self-organizing map (SOM)-based algorithm can successfully categorize a large and eclectic Internet information space (the Entertainment sub-category of Yahoo!) into manageable sub-spaces that users can successfully navigate to locate a homepage of interest to them. The SOM algorithm worked best with browsing tasks that were very broad, and in which subjects skipped around between categories. Subjects especially liked the visual and graphical aspects of the map. Subjects who tried to do a directed search, and those that wanted to use the more familiar mental models (alphabetic or hierarchical organization) for browsing, found that the map did not work well. The results from the concept space experiment were especially encouraging. There were no significant differences among the precision measures for the set of documents identified by subject-suggested terms, thesaurus-suggested terms, and the combination of subject- and thesaurus-suggested terms. The recall measures indicated that the combination of subject- and thesaurus-suggested terms exhibited significantly better recall than subject-suggested terms alone. Furthermore, analysis of the home pages indicated that there was limited overlap between the homepages retrieved by the subject-suggested and thesaurus-suggested terms. Since the retrieved homepages for the most part were different, this suggests that a user can enhance a keyword-based search by using an automatically generated concept space. Subjects especially liked the level of control that they could exert over the search, and the fact that the terms suggested by the thesaurus were “real” (i.e., originating in the homepages) and therefore guaranteed to have retrieval success. © 1998 John Wiley & Sons, Inc.

Deriving requirements for social media based community policing (2015)

Community policing helps curb high crime rate and overcome limited police resources. The success of community policing depends on active citizen participation. Previous research shows Online Social Networks (OSN) such as Facebook encourage active citizen participation during law and order situations. However, little is known about role of OSN in developing community relations between police and citizens. Developing countries such as India have limited police personnel which increases the need of community policing. This project explores perceptions of senior police officers on the role of OSN and develops a set of requirements for an OSN based system that can enhance citizens' interaction with police. From the interview of twenty officers of Indian Police Services (IPS), we show four broad aspects in which OSN helps community policing: (1) strengthen social ties, (2) enforce social norms, (3) enable citizen reporting, and (4) keep citizens informed.

Design of Aminopolymer Structure to Enhance Performance and Stability of CO2 Sorbents: Poly(propylenimine) vs Poly(ethylenimine) (2017)

Studies on aminopolymer/oxide composite materials for direct CO<sub>2</sub> capture from air have often focused on the prototypical poly(ethylenimine) (PEI) as the aminopolymer. However, it is known that PEI will oxidatively degrade at elevated temperatures. This degradation has been ascribed to the presence of secondary amines, which, when oxidized, lose their CO<sub>2</sub> capture capacity. Here, we demonstrate the use of small molecule poly(propylenimine) (PPI) in linear and dendritic architectures supported in silica as adsorbent materials for direct CO<sub>2</sub> capture from air. Regardless of amine loading or aminopolymer architecture, the PPI-based sorbents are found to be more efficient for CO<sub>2</sub> capture than PEI-based sorbents. Moreover, PPI is found to be more resistant to oxidative degradation than PEI, even while containing secondary amines, as supported by FTIR, NMR, and ESI-MS studies. These results suggest that PPI-based CO<sub>2</sub> sorbents may allow for longer sorbent working lifetimes due to an increased tolerance to sorbent regeneration conditions and suggest that the presence of secondary amines may not mean that all aminopolymers will oxidatively degrade.
A Fast and Low Computation Consumption Model for System-Level Thermal Management in 3D IC (2016)

With the rapid increment of the power density and the introduction of vertical stac k, heat dissipation has become a challenge issue. Thermal-aware placement thereby attracts more and more attentions for 3D IC. Meanwhile, as the keep-going scaling-down of IC, a huge computation consumption was caused by the large scale span. In this paper, an equivalent anisotropic thermal conductivity model was introduced to low down the computation consumption caused by the huge feature size difference. Correctness of this model was verified and the deviation from a full-scale simulation was less than 20%. By applying this model, thermal di stribution of a designed 3D IC with 1566 TSVs and 80504 hot-spots was obtained with the total computation time of about 24 minutes in a regular personal computer.
Impact of scaling silicon film thickness and channel width on SOI MOSFET with reoxidized MESA isolation (1998)

The characteristics of reoxidized MESA isolation for silicon-on-insulator (SOI) MOSFET have been studied in terms of the dependence of device performance on silicon film thickness and channel width scaling. For devices with silicon film thickness (T/sub Si/) smaller than a critical thickness, humps appear in subthreshold IV and negative threshold voltage shift is observed in narrow width devices. The width encroachment (/spl Delta/W) also increases rapidly with reducing T/sub Si/. These observations can be explained by the formation of sharp beak and accelerated sidewall oxide growth in these devices. A simple guideline is given to optimize the reoxidation process for different T/sub Si/.
Records of RNA locations in living yeast revealed through covalent marks (2020)

RNA movements and localization pervade biology, from embryonic development to disease. To identify RNAs at specific locations, we developed a strategy in which a uridine-adding enzyme is anchored to subcellular sites, where it directly marks RNAs with 3' terminal uridines. This localized RNA recording approach yields a record of RNA locations, and is validated through identification of RNAs localized selectively to the endoplasmic reticulum (ER) or mitochondria. We identify a broad dual localization pattern conserved from yeast to human cells, in which the same battery of mRNAs encounter both ER and mitochondria in both species, and include an mRNA encoding a key stress sensor. Subunits of many multiprotein complexes localize to both the ER and mitochondria, suggesting coordinated assembly. Noncoding RNAs in the course of RNA surveillance and processing encounter both organelles. By providing a record of RNA locations over time, the approach complements those that capture snapshots of instantaneous positions.

Prophylaxis of Oropharyngeal Candidiasis with Fluconazole (1990)

A total of 112 cancer patients who could ultimately be evaluated were randomly assigned in a double-blind study to receive either fluconazole or placebo as antifungal prophylaxis during hospitalization. Thrush, defined by appropriate lesions in the oropharynx and confirmed by scrapings and cultures positive for Candida species, occurred in 2% of the 58 patients given fluconazole and in 28% of the 54 patients given placebo (P = .0003). Candida species were cultured from initial throat specimens from 29 patients given fluconazole and from 26 patients given placebo. Oropharyngeal candidiasis was detected subsequently in 3% of the former patients and 54% of the latter patients (P = .0001). Adverse reactions that were probably due to or aggravated by fluconazole occurred in only four patients and consisted of transient liver function abnormalities in three instances and nausea and vomiting in one. Oral fluconazole is an effective agent for prophylaxis of oropharyngeal candidiasis in susceptible cancer patients.
Wheat and Grain Sorghum Yields as Influenced by Long-term Tillage and Nitrogen Fertilizer Application (2015)

Tillage, choice of crops in a rotation, and fertilizer management affect crop yields. Limited information exist on long - term interaction effects of tillage and nitrogen (N) fertilizer management on grain yie ld and precipitation use efficiency (PUE) in intensified cereal - based cropping systems. A study was initiated at the Kansas State University Agricultural Research Center - Hays in 1975 to investigate the effect of tillage intensity [conventional tillage (CT ), reduced tillage (RT) and No - till (NT)] and N fertilizer rates (0, 22, 45 and 67 kg N ha - 1 ) on wheat and grain sorghum yields. Grain yields and PUE for both wheat and grain sorghum were significantly ( P 67 kg N ha - 1 ) may be required to maximize both wheat and grain sorghum yields with any of the tillage systems.

Phenolic Glycosides from the Twigs of Salix glandulosa (2014)

As a part of an ongoing search for bioactive constituents from Korean medicinal plants, the phytochemical investigations of the twigs of Salix glandulosa afforded 12 new phenolic glycosides (1-12) and a known analogue (13). The structures of 1-13 were characterized by a combination of NMR methods ((1)H and (13)C NMR, (1)H-(1)H COSY, HMQC, and HMBC), chemical hydrolysis, and GC/MS. The absolute configuration of 13 [(1R,2S)-2-hydroxycyclohexyl-2'-O-trans-p-coumaroyl-β-d-glucopyranoside] was determined for the first time. Compounds 1-3, 6, and 7 exhibited inhibitory effects on nitric oxide production in lipopolysaccharide-activated murine microglial cells (IC50 values in the range 6.6-20.5 μM).

Growth hormone secretory pattern and somatomedin C plasma concentrations in newborn calves. (1987)

Plasma growth hormone (GH) and somatomedin-C (IGF-1) concentrations were measured by radioimmunoassay in 16 dairy calves during the first 20 days of postnatal life. The lowest plasma GH concentration (0.07 +/- 0.01 nmols . l-1) occurred 4 h after birth. It increased gradually until the 3rd day, to reach values similar to those measured in adult males (0.15 +/- 0.05 nmoles . l-1) and remained stable until 20 days. The lowest plasma IGF-1 concentration (3.1 +/- 0.5 nmol . l-1) was measured at 3 days, then increased at 4 days (7.6 +/- 0.6 nmol . l-1) and remained stable until 20 days of age. In nine 2-10 days-old calves, the GH secretory profile observed in blood samples collected every 30 min over a 24-h period showed 8-13 secretory spikes, without periodicity. No relationship could be demonstrated between plasma GH and IGF1 concentrations. A marked increase in plasma GH concentrations followed every morning milk feeding.

ABILBO: Analog BuILt-in block observer (2002)

This paper presents a novel multifunctional test structure called Analog BulLt-in Block Observer (ABILBO). This structure is based on analog integrators and achieves analog scan, test frequency generation and test response compaction. A high fault coverage was obtained by using a discrete switched-capacitor ABILBO for testing a biquad filter. The ABILBO area overhead and performance penalty can be very low if functional and testing circuitry are shared. This is typically the case of high order filters based on a cascade of biquads.
Quasistatisch-resonanter Mikroscanner zur adaptivenAuflösungssteuerung einer 3D ToF-Kamera (2014)

Zusammenfassung Um zukünftig eine aktive, teilautonome Interaktion von Robotern mit ihrer Umgebung zu gewährleisten, werden neuartige 3D-Sensoren benötigt, die eine hinreichend genaue Erfassung ihrer Umgebung in Echtzeit ermöglichen und sich durch hohe Robustheit und Miniaturisierung auszeichnen. Laserscanner ermöglichen zwar eine präzise und robuste Entfernungsmessung über große Entfernungen sind aber bzgl. ihrer Messrate auf etwa 1 MVoxel/s begrenzt. In diesem Beitrag wird eine neuartige MEMS basierte 3D-Kamera vorgestellt, die durch den Einsatz von quasistatisch-resonanten Mikroscannern eine schnelle und situationsbezogene Steuerung der Scanbewegung und somit in Analogie zum menschlichen Auge eine adaptive Anpassung der räumlichen Auflösung im Scanbereich ermöglicht.
Mechanisms and markers of vascular damage in ANCA-associated vasculitis (2009)

Much progress has been made in understanding the pathogenesis of anti-neutrophil cytoplasmic antibodies (ANCA)-associated small-vessel vasculitis and interaction between ANCA and micro-vascular endothelial cells are centre stage. The interactions of these key players culminate in respiratory burst of the neutrophil with release of radicals and proteases and subsequent endothelial cell and tissue damage. During the last decade, markers have become available to assess the extent and/or acuity of vascular damage in a clinical setting. First, circulating endothelial cells (CEC) have emerged as reliable surrogate markers of endothelial damage in vasculitis. More recently, endothelial microparticles have been used and appear to reflect damage and activation of the cells. Data on endothelial progenitor cells in vasculitis are sparse but intriguing while a genuine progenitor cell deficiency remains controversial. The severely damaged phenotype of CEC in vasculitis led to the hypothesis that such circulating apoptotic and/or necrotic debris may itself be a mediator of disease and first data from experimental studies have added proof to this assumption. Such effects may well contribute to a pro-inflammatory environment in ANCA-associated small-vessel vasculitis and in vascular disease in general. Here, we review mechanisms and markers of endothelial damage and repair in ANCA-associated vasculitis and put these findings into perspective.
Bayesian game based power control scheme for inter-WBAN interference mitigation (2014)

Wireless body area network (WBAN) is an emerging technology that provides socialized health monitoring service. However, the quality of service can be severely degraded by concomitant inter-WBAN interference in some specific environments where multiple WBANs are densely deployed, e.g., hospitals and senior citizen communities. In this work, we propose a Bayesian game based power control scheme to mitigate the impact of inter-WBAN interference. By modeling WBANs as players and active links as types of players in the Bayesian game model, the proposed power control scheme tries to maximize each player's expected payoff involving both throughput and energy efficiency. We prove the existence of Bayesian equilibrium (BE) for the proposed power control game and also derive a practical sufficient condition for the uniqueness of BE. A harmonic mean based algorithm is then proposed to obtain an approximation of BE point without the need to pass message among WBANs, which satisfies the non-cooperative manner for inter-WBAN interference mitigation. Simulation results show that the proposed algorithm can converge to the BE point effectively.
Age effects on survival from early breast cancer in clinical settings in Australia (2012)

Quantized Consensus of Unidirectional Pedestrian Flow based on Two-Time-Scale Hybrid Models (2018)

The convergence of pedestrian flow in a unidirectional corridor is studied based on the two-time-scale hybrid traffic models for pedestrian crowds. In the two-time-scale framework, the corridor is divided into a set of virtual lanes. The width of each lane is equal to the diameter of a pedestrian which is modeled as a disk. Being situated in a corridor, the pedestrians can either walk in a lane following each other or change to the adequate lanes. The in-lane movements of pedestrians are viewed as a one-line multi-agent dynamic system in continuous time. The lane changing behavior of pedestrians is modeled as a Markov decision process. Pedestrians will change lanes according to the transition probabilities which are functions depending on pedestrian velocities in the related lanes. Furthermore, the quantized consensus state of pedestrian flow is defined. We show that when pedestrians wish to change to faster lanes, the numbers of pedestrians in each lane converge to a balanced distribution (quantized consensus state) as shown typically in pedestrian flows. Numerical simulations and theoretical analysis are used to demonstrate the convergence properties of this method. Simulation results show that the model can capture the main features of unidirectional pedestrian flows.
