Abstract 13298: Density, Coverage and Usage of Automated External Defibrillators in Out-of-Hospital Cardiac Arrest Across Europe (2021)

Introduction: Though deployment of Automated External Defibrillators (AEDs) is increasing rapidly, AEDs are often deployed in an un-strategic manner. Consequently, little is known about the association between AED density, AED coverage of out-of-hospital cardiac arrest (OHCA), and bystander defibrillation across different countries. This study aimed to investigate the differences in AED densities (AEDS/100,000 inhabitants/1,000 km2), the AED coverage of OHCAs, and bystander defibrillation across Europe. Hypothesis: AED density is directly associated with degree of bystander defibrillation across Europe. Methods: The study is a European Sudden Cardiac Arrest network towards Prevention, Education, New Effective Treatment (ESCAPE-NET) project. We included data from Ticino (Switzerland), Lombardy (Italy), and The Capital Region (Denmark) from 2019, covering over 3.7 million inhabitants. AED accessibility was defined as the AED being accessible 24/7 or not and AED coverage was defined as the OHCA being covered by an AED within 100, 250 and 500 meters. AED coverages were calculated the same way by all participants using a free software program (QGIS). Results: AED densities were: 87.3 for Ticino, 15.2 for Lombardy, and 139.4 for The Capital Region. The percentages of OHCAs covered by any AED and by 24/7 accessible AEDs are shown in Figure 1. The calculated AED density per 1% bystander defibrillation (for the percentage of OHCAs bystander defibrillated within 100, 250 and 500m of an AED) were 34.9, 17.5 and 15.6 for Ticino, 76.0, 50.7 and 38.0 for Lombardy and 19.4, 12.6 and 11.2 for The Capital Region. Conclusion: We found great variation in both AED coverage and 24/7 AED accessibility across regions, as well as marked differences in bystander defibrillation according to local AED density. Other factors like geographical differences in the regions, optimal AED placement and citizen responder programs for AED use might explain the observed differences.
Estimation of Glottal Closure Instants in Voiced Speech Using the DYPSA Algorithm (2006)

We present the Dynamic Programming Projected Phase-Slope Algorithm (DYPSA) for automatic estimation of glottal closure instants (GCIs) in voiced speech. Accurate estimation of GCIs is an important tool that can be applied to a wide range of speech processing tasks including speech analysis, synthesis and coding. DYPSA is automatic and operates using the speech signal alone without the need for an EGG signal. The algorithm employs the phase-slope function and a novel phase-slope projection technique for estimating GCI candidates from the speech signal. The most likely candidates are then selected using a dynamic programming technique to minimize a cost function that we define. We review and evaluate three existing methods of GCI estimation and compare the new DYPSA algorithm to them. Results are presented for the APLAWD and SAM databases for which 95.7% and 93.1% of GCIs are correctly identified
Protease-armed bacteria in the skin (2012)

The skin constitutes a formidable barrier against commensal and pathogenic bacteria, which permanently and transiently colonise the skin, respectively. Commensal and pathogenic species inhabiting skin both express proteases. Whereas proteases secreted by commensals contribute to homeostatic bacterial coexistence on skin, proteases from pathogenic bacteria are used as virulence factors, helping them colonise skin with breached integrity of the epithelial layer. From these initial sites of colonisation, pathogens can disseminate into deeper layers of skin, possibly leading to the spread of infection. Secreted bacterial proteases probably play an important role in this process and in the deterrence of innate defence mechanisms. For example, Staphylococcus aureus proteases are essential for changing the bacterial phenotype from adhesive to invasive by degrading adhesins on the bacterial cell surface. Secreted staphylococcal proteases mediate pathogen penetration by degrading collagen and elastin, essential components of connective tissue in the dermis. The activation of the contact system and kinin generation by Streptococcus pyogenes and S. aureus proteases contributes to an inflammatory reaction manifested by oedema, redness and pain. Kinin-enhanced vascular leakage might help bacteria escape into the circulation thereby causing possible systemic dissemination of the infection. The inflammatory reaction can also be fueled by the activation of protease-activated receptors on keratinocytes. Concomitantly, bacterial proteases are involved in degrading antimicrobial peptides, disarming the complement system and neutrophils and preventing the infiltration of the infected sites with immune cells by inactivation of chemoattractants. Together, this provides protection for colonising and/or invading pathogens from attack by antibacterial forces of the skin.
Effective corrosion inhibition performance of La(NO3)3 doped sol-gel coating on galvanized steel sheet (2014)

Purpose – The aim of this work was to study the effect of La(NO 3 ) 3 on the corrosion behavior of sol-gel coating prepared by hydrolysis of 3-glycidoxypropyl)methyldiethoxysilane and 3-aminopropyltriethoxysilane. Generally, galvanized steel is subjected to a hexavalent chromium passivation treatment. Hexavalent chromium passivation is not an environment friendly product and researchers are looking for a suitable alternative for chromium passivation treatment. Some of the potential alternatives are silicate conversion coating or the use of silane-based coatings. In this context, sol-gel coating was investigated as a potential replacement for hazardous hexavalent chromium passivation treatment. Design/methodology/approach – The sol-gel film was deposited on galvanized steel sheet by the dip coating method. The molecular vibration and chemical properties of sol-gel solution and coated films were obtained by infrared spectroscopy. Images from a scanning electron microscope were obtained to characterize the morphology of the film. The corrosion resistance of the coated samples was evaluated by electrochemical impedance spectroscopy (EIS), potentiodynamic polarization curves and salt spray tests. Findings – The results indicated that La(NO 3 ) 3 -doped coatings were more resistance to corrosion than undoped coating. The coating doped with 0.5 per cent La(NO 3 ) 3 offered improved corrosion protection due to the inhibitive action of the La3+ ion. Originality/value – This result can provide a reference for the development of chromium-free passivation for galvanized sheeting.
EXPERIMENTAL ACUTE KIDNEY INJURY (2014)

Introduction and Aims: Acute interstitial nephritis (AIN) is a common cause of acute kidney injury (AKI). In severe cases, AIN may progress to chronic kidney disease or end-stage renal disease. We previously reported that WNT10A is a novel angio/ stromagenic factor in wound healing and organ fibrosis. In this study, we investigated the role of WNT10A in fibrotic progression of AIN. Methods: Kidney biopsy specimens from 25 AKI patients (all men, 60 years) treated in our hospital between 2007 and 2013 were examined for WNT proteins, -SMA, and fibronectin expression by immunohistochemistry. The relationship between each WNT proteins expression level and estimated glomerular filtration rate (eGFR) was evaluated by the Mann-Whitney U test. COS1 cells (kidney fibroblasts from African green monkey) were transfected with a WNT10A expression plasmid or a siRNA targeting peroxiredoxin 5 (PRDX5). The effects of WNT10A overexpression and PRDX5 knockdown on proliferation and hydrogen peroxide induced cytotoxicity were measured by WST-8 assay. Results: The 10 patients exhibiting WNT10A expression in biopsy tissue had significantly lower eGFR values (median, 11.12 mL/min per 1.73 m 2 ; range, 7.16-28.15 mL/min per 1.73 m 2 ) than the 15 patients exhibiting no detectable WNT10A expression (34.70, 8.37-134.58; p = 0.0033). There was no significant relationship between eGFR and the expression level of any other WNT protein examined (WNT-1, -3, and -4). Overexpression of WNT10A in COS1 cells enhanced proliferation, fibronectin expression, PRDX5 expression, and resistance to hydrogen peroxide, while PRDX5 downregulation sensitized COS1 cells to hydrogen peroxide. Conclusions: WNT10A expression may promote fibrotic progression and kidney dysfunction in AIN. Blockade of WNT10A expression may be a feasible therapeutic strategy against kidney fibrosis.
Statistically Robust Design of Linear MIMO Transceivers (2008)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> The treatment of channel state information (CSI) is critical in the design of MIMO systems. Accurate CSI at the transmitter is often not possible or may require high feedback rates. Herein, we consider the robust design of linear MIMO transceivers with perfect CSI either at the transmitter or at both sides of the link. The framework considers the design problem where the imperfect CSI consists of the channel mean and covariance matrix or, equivalently, the channel estimate and the estimation error covariance matrix. The robust transceiver design is based on a general cost function of the average MSEs as well as a design with individual MSE based constraints. In particular, a lower bound of the average MSE matrix is explored for the design when only the CSI at the transmitter is imperfect. Under different CSI conditions, the proposed robust transceivers exhibit a similar structure to the transceiver designs for perfect CSI, but with a different equivalent channel and/or noise covariance matrix. </para>
Nuclear modification of Y states in pPb collisions at sNN=5.02TeV (2022)

Production cross sections of , , and states decaying into in proton-lead (pPb) collisions are reported using data collected by the CMS experiment at sNN=5.02TeV. A comparison is made with corresponding cross sections obtained with pp data measured at the same collision energy and scaled by the Pb nucleus mass number. The nuclear modification factor for is found to be . Similar results for the excited states indicate a sequential suppression pattern, such that . The suppression of all states is much less pronounced in pPb than in PbPb collisions, and independent of transverse momentum and center-of-mass rapidity of the individual state in the studied range and . Models that incorporate final-state effects of bottomonia in pPb collisions are in better agreement with the data than those which only assume initial-state modifications.

Open nanofluidic films with rapid transport and no analyte exchange for ultra-low sample volumes (2018)

Moving to ultra-low (<100 nL) sample volumes presents numerous challenges, many of which can be resolved by implementation of open nanofluidic films. These nanofluidic films are fabricated using a hexagonal network of gold-coated open microchannels which capture all of the following innovative advantages: (1) sample volumes of <100 nL cm-2; (2) zero analyte exchange and loss with the film materials; (3) rapid and omni-directional wicking transport of >500 nL min-1 per square of film; (4) ultra-simple roll-to-roll fabrication; (5) stable and bio-compatible super-hydrophilicity for weeks in air by peptide surface modification. Validation includes both detailed in vitro characterization and in vivo validation with sweat transport from the human skin. Sampling times (skin-to-sensor) of <3 min were achieved, setting new benchmarks for the field of wearable sweat sensing. This work addresses significant challenges for sweat biosensing, or for any other nano-liter regime (<100 nL) fluid sampling and sensing application.
Accessibility and Availability of Gas Stations for Liquid Fuel Supply During Severe Weather Events (2023)

Energy infrastructure is a pivotal lifeline with wider inter-dependencies. Electric power is essential to the continued functioning of critical assets; liquid fuels and other physical primary energy commodities that are used to supply the local energy needs of these assets during extreme events when electricity infrastructure is compromised. During Superstorm Sandy, the disruption of fuel supplies in the Tri-state area necessitated increasing situational awareness about oil and natural gas (ONG) systems to redirect fuel supplies to first responders and for restoration efforts. During winter storm events over the past several years, the demand for ONG for heating and power generation has skyrocketed in the north-east, which subsequently had caused ONG price to hit their highest level in years. ONG is a major energy source for restoration and recovery activities. However, very little, if any, situational awareness information about ONG supply and demand is available to those coordinating emergency efforts. Often this lack of information is due to the decentralized nature of the ONG supply chain and proprietary data maintained by private entities. To understand the impact of fuel availability on response and recovery efforts, this research focuses on (i) determining the accessibility to gas stations for liquid fuel supply across space and time, and (ii) examining the spatio-temporal variation of fuel availability and demand during extreme weather events. The broader scope of the project focuses on providing spatio-temporal situational awareness information about ONG availability and demand across the fuel supply chain for positioning of resources for response activities.
Trends in the Association Between Age and In-Hospital Mortality After Percutaneous Coronary Intervention (2009)

In-hospital mortality after percutaneous coronary intervention has fallen for all age groups over the past 6 years. However, the largest absolute reduction was seen among patients 80 years of age or older.
Phantom model of transcutaneous electrical stimulation with kilohertz signals (2015)

Transcutaneous electrical stimulation (TES) of nerve fibers may be optimized by overcoming the impedance of the skin using high-frequency (HF) stimulation signals. The excitation properties of nerve fibers depend on the spatiotemporal distribution of the extracellular field, and therefore quantifying the potentials during HF-TES is warranted. We present a physical phantom of TES that includes elements representing the skin and underlying tissue, and incorporates dispersion of the electrical conductivity as required during HF stimulation. We used both agar-based gels and biological materials, and doped the gels with graphite to add dispersion. We measured the dielectric properties of the materials, which we modified by adjusting the concentration of sodium chloride and graphite. We assembled up to three layers of material, and quantified the impedance as a function of frequency and depth. The impedance at any depth decayed with frequency, which suggests that HF signal may reach deeper structures in TES.
AdaShare: Learning What To Share For Efficient Deep Multi-Task Learning (2019)

Multi-task learning is an open and challenging problem in computer vision. The typical way of conducting multi-task learning with deep neural networks is either through handcrafted schemes that share all initial layers and branch out at an adhoc point, or through separate task-specific networks with an additional feature sharing/fusion mechanism. Unlike existing methods, we propose an adaptive sharing approach, called AdaShare, that decides what to share across which tasks to achieve the best recognition accuracy, while taking resource efficiency into account. Specifically, our main idea is to learn the sharing pattern through a task-specific policy that selectively chooses which layers to execute for a given task in the multi-task network. We efficiently optimize the task-specific policy jointly with the network weights, using standard back-propagation. Experiments on several challenging and diverse benchmark datasets with a variable number of tasks well demonstrate the efficacy of our approach over state-of-the-art methods.

Isotropic band gaps and freeform waveguides observed in hyperuniform disordered photonic solids (2013)

Recently, disordered photonic media and random textured surfaces have attracted increasing attention as strong light diffusers with broadband and wide-angle properties. We report the experimental realization of an isotropic complete photonic band gap (PBG) in a 2D disordered dielectric structure. This structure is designed by a constrained optimization method, which combines advantages of both isotropy due to disorder and controlled scattering properties due to low-density fluctuations (hyperuniformity) and uniform local topology. Our experiments use a modular design composed of Al2O3 walls and cylinders arranged in a hyperuniform disordered network. We observe a complete PBG in the microwave region, in good agreement with theoretical simulations, and show that the intrinsic isotropy of this unique class of PBG materials enables remarkable design freedom, including the realization of waveguides with arbitrary bending angles impossible in photonic crystals. This experimental verification of a complete PBG and realization of functional defects in this unique class of materials demonstrate their potential as building blocks for precise manipulation of photons in planar optical microcircuits and has implications for disordered acoustic and electronic band gap materials.

5‐Aminolevulinic acid and sodium ferrous citrate ameliorate muscle aging and extend healthspan in Drosophila (2021)

Declines in mitochondrial functions are associated with aging. The combination of 5-aminolevulinic acid (5-ALA) and sodium ferrous citrate (SFC) improves mitochondrial functions in cultured cells. In this study, we investigated the effects of dietary supplementation with 5-ALA and SFC (5-ALA/SFC) on the healthspan and life span of Drosophila melanogaster. Adult Drosophila fruit flies were fed cornmeal food containing various concentrations of 5-ALA/SFC. Locomotor functions, life span, muscle architecture, and age-associated changes in mitochondrial function were analyzed. We found that feeding 5-ALA/SFC mitigated age-associated declines in locomotor functions and extended organismal life span. Moreover, 5-ALA/SFC preserved muscle architecture and maintained the mitochondrial membrane potential in aged animals. Since 5-ALA phosphate/SFC is used as a human dietary supplement, our results suggest that it could be used to slow the age-related declines in muscle functions, prevent age-associated clinical conditions such as frailty, and extend healthspan and life span.
Lab-on-Fiber biosensing for cancer biomarker detection (2015)

This work deals with a novel Lab-on-Fiber biosensor able to detect in real time thyroid carcinomas biomarkers. The device is based on a gold nanostructure supporting localized surface plasmon resonances (LSPR) directly fabricated on the fiber tip by means of electron beam lithography and lift-off process. Following a suitable chemical and biological functionalization of the sensing area, human Thyroglobulin has been detected at nanomolar concentrations. Also, compatibility with full baseline restoration, achieved through biomarkers/bioreceptors dissociation, has been demonstrated.
Memory module-level testing and error behaviors for phase change memory (2012)

Phase change memory (PCM) is a promising technology to solve energy and performance bottlenecks for memory and storage systems. To help understand the reliability characteristics of PCM devices, we present a simple fault model to categorize four types of PCM errors. Based on our proposed fault model, we conduct extensive experiments on real PCM devices at the memory module level. Numerical results uncover many interesting trends in terms of the lifetime of PCM devices and error behaviors. Specifically, PCM lifetime for the memory chips we tested is greater than 14 million cycles, which is much longer than for flash memory devices. In addition, the distributions for four types of errors are quite different. These results can be used for estimating PCM lifetime and for measuring the fabrication quality of individual PCM memory chips.
