Dopant selection rules for extrinsic tunability of HfO x RRAM characteristics: A systematic study (2013)

Recently, resistive random access memory (RRAM) has been explored as a promising technology for applications including on-chip memories, 3D-FPGA and neuromorphic computing systems. For systems with RRAM integration, it is beneficial to have better control of device characteristics to provide large design space and advanced functionalities. For example, in order to mimic the human nervous system with a complex hierarchy, it is desirable to develop multiple, well-separated RRAM characteristics on a single chip. However, intrinsic tuning of device parameters is subject to process restrictions and performance trade-off. In this paper, we present the first systematic approach to understand and utilize the doping effects for tuning RRAM characteristics. HfOx-based RRAM devices with 5 different dopants are fabricated to demonstrate the substantial tunability of key parameters including forming voltage, SET voltage and ON/OFF ratio. To explain the experimental observations, detailed ab initio calculations are performed to model the dopant-vacancy and dopant-filament interactions. The effects of 12 candidate dopants on forming and switching processes are analyzed to provide universal guidelines for dopant selection. Based on the improved tunability, novel design methodologies are further proposed to enable high-performance and multi-level RRAM devices.
Observer-Based Finite-Time Adaptive Fuzzy Control for Nontriangular Nonlinear Systems With Full-State Constraints (2020)

This article focuses on finite-time adaptive fuzzy output-feedback control for a class of nontriangular nonlinear systems with full-state constraints and unmeasurable states. Fuzzy-logic systems and the fuzzy state observer are employed to approximate uncertain nonlinear functions and estimate the unmeasured states, respectively. In order to solve the algebraic loop problem generated by the nontriangular structure, a variable separation approach based on the property of the fuzzy basis function is utilized. The barrier Lyapunov function is incorporated into each step of backstepping, and the condition of the state constraint is satisfied. The dynamic surface technique with an auxiliary first-order linear filter is applied to avoid the problem of an "explosion of complexity." Based on the finite-time stability theory, an adaptive fuzzy controller is constructed to guarantee that all signals in the closed-loop system are bounded, the tracking error converges to a small neighborhood of the origin in a finite time, and all states are ensured to remain in the predefined sets. Finally, the simulation results reveal the effectiveness of the proposed control design.

Fast and cost-effective SARS-CoV-2 variant detection using Oxford Nanopore full-length spike gene sequencing (2023)

Most biologically relevant and diagnostic mutations in the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) genome have been identified in the S gene through global genomic surveillance efforts. However, large-scale whole-genome sequencing (WGS) is still challenging in developing countries due to higher costs, reagent delays and limited infrastructure. Consequently, only a small fraction of SARS-CoV-2 samples are characterized through WGS in these regions. Here, we present a complete workflow consisting of a fast library preparation protocol based on tiled amplification of the S gene, followed by a PCR barcoding step and sequencing using Nanopore platforms. This protocol facilitates fast and cost-effective identification of main variants of concern and mutational surveillance of the S gene. By applying this protocol, report time and overall costs for SARS-CoV-2 variant detection could be reduced, contributing to improved genomic surveillance programmes, particularly in low-income regions.

The use of Advanced Refractory Ceramic Materials to Address Industrial Energy Efficiency Challenges (2016)

Novel refractory ceramic systems and application techniques have been used to improve the energy efficiency of traditional industrial processes through increased furnace efficiency. Examples of advances in refractory materials for furnace applications related to the aluminum industry, biomass and coal gasification, the glass industry, and lime kilns will be highlighted, along with how these advances can be applied to other processes. The energy savings strategies discussed focus on the reduction of chemical reactions, the elimination of mechanical degradation caused by these service environments, the reduction of temperature limitations for applied materials, and the elimination of costs or loss of productivity due to installation and repair issues. Key results of several case studies resulting from US Department of Energy (DOE) funded research programs will be discussed with emphasis on applicability of these results to high temperature furnace applications and needed research directions for the future.
Inactivation Kinetics and Replication Cycle Inhibition of Coxsackievirus B5 by Free Chlorine (2023)

The kinetics of coxsackievirus serotype B5 (CVB5) inactivation with free chlorine is characterized over a range of pH and temperature relevant to drinking water treatment with the primary goal of selecting experimental conditions used for assessing inactivation mechanisms. The inactivation kinetics identified in our study is similar to or slower than experimental data reported in the literature and thus provides a conservative representation of the kinetics of CVB5 inactivation for free chlorine that could be useful in developing future regulations for waterborne viral pathogens including adequate disinfection treatment for CVB5. Untreated and free chlorine-treated viruses, and host cells synchronized-infected with these viruses, are analyzed by a reverse transcription-quantitative polymerase chain reaction (RT-qPCR) method with the goal of quantitatively investigating the effect of free chlorine exposure on viral genome integrity, attachment to host cell, and viral genome replication. The inactivation kinetics observed results from a combination of hindering virus attachment to the host cell, inhibition of one or more subsequent steps of the replication cycle, and possibly genome damage.
THE SYNTHESIS OF NONLINEAR FEEDBACK SHIFT REGISTERS (1963)

Two domains that describe the behavior of a feedback shift register were developed. These are the sequence and polynomial domains, which are analogous to the frequency and time domains in the description of continuous systems. The domains are related by an expansion of orthogonal functions. The synthesis procedure developed in the polynomial domain consists of four steps: (1) constructing a finite field with the necessary properties; (2) finding the polynomials that correspond to the desired output sequences; (3) obtaining the polynomial that describes the shift register as a product of the polynomials that represent the desired output sequence; and (4) obtaining the feedback network from the polynomial that describes the shift register. In the procedure, the output sequences are mapped to the roots of irreducible polynomials, thereby providing an algebraic description of the register's behavior. To synthesize the shift register in the sequence domain, several properties of the output sequences are needed. The class of sequences and state graphs corresponding to shift-register behavior is established. The cycles and output sequences of a simple, circulating shift register are used to synthesize an arbitrary feedback shift register. (Author)
Landscape and Perception (Website) (2012)

http://www.landscape-perception.com This website documents a collaborative programme of research conducted by Wozencroft and Paul Devereux (Princeton University), a key protagonist of a new area of archaeological enquiry, archaeoacoustics, and presents new strategies and outcomes for repositioning attitudes towards heritage. Undertaken over a seven-year period, the research investigates sound and acoustics as key features of prehistoric sacred sites, which have yet to be fully assessed in terms of sonic features and peculiarities. The project significantly expands interdisciplinary research in the areas of art, sound and archaeology, linking analogue pre-computer modes of perception with a distribution method that makes the best of contemporary forms. The research has been published in Time and Mind 4 (2); ‘The end my friend’ in The Design Journal 15 (2); ‘The hills are alive’ in The Wire magazine 339 (Spring 2012) and expanded online at www.thewire.co.uk, and in keynote lectures and seminars at the ‘Punkt’ festival, Kristiansand (2012), ‘Soundworks’, London (2012) and 9th European Academy of Design conference, Porto (2011). The project looks at two locations, including the Preseli hills in Pembrokeshire, site of the bluestones that were transported to Stonehenge in approximately 2500 BC. A parallel study has been made of Avebury, Wiltshire, a constructed sacred site. Wozencroft and Devereux’s investigations at Preseli have unearthed and documented a range of sonic phenomena that defy analysis – a series of lithophones, ringing rocks and other echo-location features that indicate an awareness of sound and acoustics not previously accounted for in the experience of early Homo sapiens. The research explores the potential recognition of Stonehenge as both a sound space and a visual theatre for ritual events. It has also raised key questions about the concentration and sonic dimensions of sacred/prehistoric/protected sites at Preseli, which has 49 – more than any other area in the British Isles.
Chemoenzymatic Solution- and Solid-Phase Synthesis ofO-Glycopeptides of the Mucin Domain of MAdCAM-1. A General Route toO-LacNAc,O-Sialyl-LacNAc, andO-Sialyl-Lewis-X Peptides (1997)

An efficient and general method for the solid-phase synthesis of glycopeptides containing an O-linked sialyl-Lewis-X (SLex) tetrasaccharide is described. Using a combined chemoenzymatic approach, the first synthesis of an unnatural β-O-linked SLex attached to a partial sequence of the mucin domain of the L-selectin ligand MAdCAM-1, was demonstrated. A resin-bound O-glycoconjugate was synthesized from a new Fmoc-threonine building block which carries an O-unprotected β-linked N-acetylglucoseamine (GlcNAc) moiety. The acid- and base-stable HYCRON-linker enabled the complete removal of all protecting groups on solid phase. Glycosyltransferases were employed to extend the glycan on supported and unsupported O-GlcNAc-octapeptide substrates. The acid- and base-sensitive O-glycopeptides were released under practically neutral conditions, taking advantage of the palladium(0)-catalyzed cleavage of the allylic linkage. Studies toward the selective O-deacetylation of ester-linked glycopeptides possessing O-acetyl-protected carbohydrates are also reported.
The Temporal Atrial Fibrillation Pattern during the Blanking Period after Atrial Fibrillation Ablation Is Associated with Later AF Recurrence (2016)

Objective: Atrial fibrillation (AF) ablation can introduce a period of transient electrical instability for an extended period after the procedure. Several investigators and consensus statements indicate that arrhythmias observed during the 3 month "blanking period" should not be taken into account for evaluation of procedural success. The aim of the present study was to evaluate if the quantity and temporal pattern of the arrhythmias during the blanking period can provide valuable insights regarding future AF recurrence and indirectly the success of the ablation.

The recurrent IgH translocations are highly associated with nonhyperdiploid variant multiple myeloma (2003)

Aneuploid is ubiquitous in multiple myeloma (MM), and 4 cytogenetic subcategories are recognized: hypodiploid (associated with a shorter survival), pseudodiploid, hyperdiploid, and near-tetraploid MM. The hypodiploid, pseudodiploid, and near-tetraploid karyotypes can be referred to as the nonhyperdiploid MM. Immunoglobulin heavy-chain (IgH) translocations are seen in 60% of patients. We studied the relation between aneuploidy and IgH translocations in MM. Eighty patients with MM and abnormal metaphases were studied by means of interphase fluorescent in situ hybridization (FISH) to detect IgH translocations. We also studied a second cohort of 199 patients (Eastern Cooperative Oncology Group [ECOG]) for IgH translocations, chromosome 13 monosomy/deletions (Delta13), and ploidy by DNA content. Mayo Clinic patients with abnormal karyotypes and FISH-detected IgH translocation were more likely to be nonhyperdiploid (89% versus 39%, P <.0001). Remarkably, 88% of tested patients with hypodiploidy (16 of 18) and 90% of tested patients with tetraploidy (9 of 10) had an IgH translocation. ECOG patients with IgH translocations were more likely to have nonhyperdiploid MM by DNA content (68% versus 21%, P <.001). This association was seen predominantly in patients with recurrent chromosome partners to the IgH translocation (11q13, 4p16, and 16q23). The classification of MM into hyperdiploidy and nonhyperdiploidy is dictated largely by the recurrent (primary) IgH translocations in the latter.
A Backward-Forward Sweep Based Power Flow Algorithm for Generalized AC-DC Distribution Network with Distributed Generations (2023)

Developing a power flow (PF) methodology for the AC-DC distribution network is complex but important, especially due to the involvement of power converters. In this work, a Backward-Forward Sweep (BFS) approach developed based on graph theory and matrix algebra is proposed for solving the PF for both the radial and mesh configured AC-DC distribution networks with distributed energy resources (DERs). For this purpose, first, the per-unit current, voltage, and power model of the 3- <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$\phi$</tex-math></inline-formula> pulse width modulated (PWM) rectifier, 3- <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$\phi$</tex-math></inline-formula> PWM inverter, and DC/DC power converter have been developed.

The major benefits of the proposed algorithm are that it can incorporate various functional/control modes of the aforementioned converters. The feasibility of the proposed power flow algorithm has been explored on AC-DC distribution test networks. The test results show that the approach is feasible and precise.

Seeing Beyond Your Nose? The Effects of Lifelong Olfactory Sensory Deprivation on Cerebral Audio-visual Integration (2021)

Lifelong auditory and visual sensory deprivation have been demonstrated to alter both perceptual acuity and the neural processing of remaining senses. Recently, it was demonstrated that individuals with anosmia, i.e. complete olfactory sensory deprivation, displayed enhanced multisensory integration performance. Whether this ability is due to a reorganization of olfactory processing regions to focus on cross-modal multisensory information or whether it is due to enhanced processing within multisensory integration regions is not known. To dissociate these two outcomes, we investigated the neural processing of dynamic audio-visual stimuli in individuals with congenital anosmia and matched controls (both groups, n = 33) using functional magnetic resonance imaging. Specifically, we assessed whether the previously demonstrated multisensory enhancement is related to cross-modal processing of multisensory stimuli in olfactory associated regions, the piriform and olfactory orbitofrontal cortices, or enhanced multisensory processing in established multisensory integration regions, the superior temporal and intraparietal sulci. No significant group differences were found in the a priori hypothesized regions using region of interest analyses. However, exploratory whole-brain analysis suggested higher activation related to multisensory integration within the posterior superior temporal sulcus, in close proximity to the multisensory region of interest, in individuals with congenital anosmia. No group differences were demonstrated in olfactory associated regions. Although results were outside our hypothesized regions, combined, they tentatively suggest that enhanced processing of audio-visual stimuli in individuals with congenital anosmia may be mediated by multisensory, and not primary sensory, cerebral regions.
Remote Control Management for Large Scale FM Transmitter Sites (2008)

This paper proposes a PLC and SCADA based system for remote control management of Large Scale FM Transmitter Sites. FM Broadcasting began in Malaysia in the 70’. It provided improvements over AM broadcasting producing higher quality service to the listener. As the number of FM services has increased rapidly, the number of transmitter sites also increased. The need for monitoring the performance of transmitter site equipment such as electrical systems, generators, air conditioning system, fire system, transmitters, and communication systems is becoming critical as these sites are becoming larger and more sophisticated. The proposed system can be used to monitor, manage, control and measure transmitter site parameters and performance from a networked computer or a dial up computer. Status and alarms can be monitored in real time with theassistance of custom designed SCADA system. If faults are detected at transmitter sites, the PLC formulates and sends the corresponding alarm codes to a centralized control centre. The system was set up and tested through rigorous simulations of the transmitter site failures and evaluated for seven months. The proposed system has been installed and continuously operated on live FM transmission system.
Imitation of spin density wave order in Cu3Nb2O8 (2020)

Spin density waves, based on modulated local moments, are usually associated with metallic materials, but have recently been reported in insulators which display coupled magnetic and structural order parameters. We discuss one such example, the multiferroic ${\mathrm{Cu}}_{3}{\mathrm{Nb}}_{2}{\mathrm{O}}_{8}$, which is reported to undergo two magnetic phase transitions, first to an unknown antiferromagnetic phase at ${T}_{N}\ensuremath{\approx}26.5\phantom{\rule{0.16em}{0ex}}\text{K}$, and then to a helicoidal structure coupled to an electric polarization below ${T}_{2}\ensuremath{\approx}24\phantom{\rule{0.16em}{0ex}}\text{K}$ [R. D. Johnson et al., Phys. Rev. Lett. 107, 137205 (2011)] which breaks the crystallographic inversion symmetry. By analogy with other complex oxides, one might naturally expect this intermediate phase to be a spin density wave phase. We apply spherical polarimetry to confirm the low-temperature magnetic structure, yet only observe a single magnetic phase transition to helicoidal order. We argue that the reported unknown phase actually supports an imitation spin density wave which originates from a decoupling of the components of the magnetic order parameter, as allowed by symmetry and driven by thermal fluctuations. This provides a mechanism for the magnetic, but not nuclear, structure to break inversion symmetry thereby creating an intermediate phase in the proximity of ${\mathrm{T}}_{N}$ which imitates a spin density wave. As the temperature is reduced, this intermediate structure destabilizes the crystal such that a structural chirality is induced, as reflected by the emergence of the electric polarization, and the imitation spin density wave relaxes into a generic helicoid. This scenario in which critical fluctuations allow the magnetic structure to break inversion symmetry while the crystal structure remains centrosymmetric might be relevant to other complex multiferroics.
