Coping with restructuring (1995)

The purpose of this study was to test the effectiveness of purposeful attempts to cope with stress by senior educational administrators in an Australian state education department of over 2,000 schools and employing teaching and administrative staff in excess of 60,000. At the time of the study this department was undergoing the initial stages of large‐scale restructuring, moving from a centralized system of management to a school‐centred, decentralized structure. This provided a unique opportunity to examine the ways in which senior executives respond in a time of discontinuous change. Presents general findings of a self‐report coping strategies questionnaire and reveals some significant relationships between general wellbeing, personality type and coping strategies.
Time-integrating interferometry using photorefractive fanout (1988)

We have experimentally demonstrated a single-beam interferometer that effectively subtracts an exponentially weighted history of the input from the current value, thus functioning as a novelty filter. The single-beam interferometer uses signal depletion due to noise amplification (fanout) in a specially cut crystal of photorefractive BaTiO(3). To demonstrate its real-time operation we used a Hughes liquid-crystal light valve to convert a video image into a phase- and/or amplitude-modulated input signal. Potential applications of this interferometer include image-clutter removal, motion detection and tracking, edge enhancement, and image time differentiation.
Design fabrication and characterisation of polyaniline and multiwall carbon nanotubes composites‐based patch antenna (2015)

This study presents the conception, simulation, realisation and characterisation of a patch antenna made of a composite based on polyaniline (PANI) and multiwall carbon nanotubes (MWCNTs). The antenna is designed to operate at the frequency of 4.5 GHz; the dielectric substrate used is Rogers RT/Duroid ® 5870 which has a dielectric permittivity of 2.33 and a loss tangent of 0.0012. The conductive polymer (PANI/MWCNTs) fabricated has a conductivity of 4500 S/m. The performance of the proposed antenna is investigated as a function of the thickness of the conductive polymer. The experimental results show an antenna gain of 5.18 dB for a PANI/MWCNTs thickness of 110 μm. The results obtained suggest that this kind of conductive polymers are good candidates for future applications based on organic electronics.
Sr 3 Al 2 O 5 Cl 2 : Ce 3 + , Eu 2 + : A potential tunable yellow-to-white-emitting phosphor for ultraviolet light emitting diodes (2009)

The Sr3Al2O5Cl2:Ce3+,Eu2+ phosphors were prepared by solid state reaction. The obtained phosphors exhibit a strong absorption in the UV-visible region and have two intense emission bands at 444 and 609 nm. The energy transfer from the Ce3+ to Eu2+ ions was observed, and the critical distance has been estimated to be about 24.5 Å by spectral overlap method. Furthermore, the developed phosphors can generate lights from yellow-to-white region under the excitation of UV radiation by appropriately tuning the activator content, indicating that they have potential applications as an UV-convertible phosphor for white light emitting diodes.
Oxidative Degradation of Organophosphorous Pesticides by N-Halamine Fabrics (2009)

Cotton and cotton/polyester fabrics containing halamine structures were able to react with certain organophosphorus pesticides upon contact. The reaction occurred at thione group in methyl parathion and malathion, and reaction products were oxon compounds. The fabric containing imide and amide halamine structures were able to oxidize 90% of methyl parathion in less than 2 h of contact time under room temperature, while the amine halamine structure needed longer time to reach the same level of oxidation. The reaction was endothermic, and the oxidation rate was in first order to the concentrations of the pesticides.
Activity-Based Detection of Consumption of Synthetic Cannabinoids in Authentic Urine Samples Using a Stable Cannabinoid Reporter System (2017)

Synthetic cannabinoids (SCs) continue to be the largest group of new psychoactive substances (NPS) monitored by the European Monitoring Center of Drugs and Drugs of Abuse (EMCDDA). The identification and subsequent prohibition of single SCs has driven clandestine chemists to produce analogues of increasing structural diversity, intended to evade legislation. That structural diversity, combined with the mostly unknown metabolic profiles of these new SCs, poses a big challenge for the conventional targeted analytical assays, as it is difficult to screen for "unknown" compounds. Therefore, an alternative screening method, not directly based on the structure but on the activity of the SC, may offer a solution for this problem. We generated stable CB1 and CB2 receptor activation assays based on functional complementation of a split NanoLuc luciferase and used these to test an expanded set of recent SCs (UR-144, XLR-11, and their thermal degradation products; AB-CHMINACA and ADB-CHMINACA) and their major phase I metabolites. By doing so, we demonstrate that several major metabolites of these SCs retain their activity at the cannabinoid receptors. These active metabolites may prolong the parent compound's psychotropic and physiological effects and may contribute to the toxicity profile. Utility of the generated stable cell systems as a first-line screening tool for SCs in urine was also demonstrated using a relatively large set of authentic urine samples. Our data indicate that the stable CB reporter assays detect CB receptor activation by extracts of urine in which SCs (or their metabolites) are present at low- or subnanomolar (ng/mL) level. Hence, the developed assays do not only allow activity profiling of SCs and their metabolites, it may also serve as a screening tool, complementing targeted and untargeted analytical assays and preceding analytical (mass spectrometry based) confirmation.
A new multi-channel MAC protocol with on-demand channel assignment for multi-hop mobile ad hoc networks (2002)

The wireless mobile ad hoc network (MANET) architecture has received a lot of attention recently. This paper considers the access of multiple channels in a MANET with multi-hop communication behavior. We point out several interesting issues when using multiple channels. We then propose a new multi-channel MAC protocol, which is characterized by the following features: (i) it follows an "on-demand" style to assign channels to mobile hosts, (ii) the number of channels required is independent of the network topology and degree, (iii) it flexibly adapts to host mobility and only exchanges few control messages to achieve channel assignment and medium access, and (iv) no clock synchronization is required. Compared to existing protocols, some assign channels to hosts statically (thus a host will occupy a channel even when it has no intention to transmit) some require a number of channels which is a function of the maximum connectivity, and some necessitate a clock synchronization among all hosts in the MANET. Extensive simulations are conducted to evaluate the proposed protocol.
Treatment of high risk symptomatic intracranial atherosclerosis with balloon mounted coronary stents and Wingspan stents: single center experience over a 10 year period (2011)

Stenting of symptomatic intracranial atherosclerosis in a high risk subset of cases with advanced degree of luminal stenosis may be associated with an increased early risk of recurrent ischemic stroke.
Dielectric Properties of Two Polar Nematic Liquid Crystals (1991)

We report in this paper the dielectric properties of two polar nematic liquid crystals p-methoxybenzylidene-p'cyanoaniline (MBCA) and p-cyanobenzylidene-p'methoxyaniline (CBMA). The effect induced by dc and ac electric fields as well as magnetic field resulting to a deformation of the nematic director was studied at 10 kHz and 1 kHz. The dielectric anisotropies, splay elastic constants and diamagnetic anisotropies as well as the correlation factors are investigated by capacitance measurements. These results are discussed in terms of molecular properties and molecular degree association.
Nonlinear transfer functions (1996)

This paper is concerned with nonlinear transfer function analysis. We propose a test statistic to detect nonlinearity of a transfer function. Simulation study shows that the test works reasonably well in finite samples for the nonlinear models commonly used in the literature. We then discuss nonlinear transfer function modeling and the contribution of nonlinear components in a given model. For illustration, we apply the test to several data sets and use a real example to show that Substantial gain may result from using simple nonlinear transfer Functions.
Low temperature melting behavior of CO 2 crystallized modified PETs (1995)

Abstract Differential scanning calorimetry (DSC) analysis has been performed on modified and commericial amorphous samples of poly(ethylene terephthalate) (PET) crystallized by high pressure carbon dioxide (CO 2 ). Two endothermic peaks are present in the DSC scans of all the carbon dioxide‐treated samples. A qualitatively analogous behavior has been detected in the case of amorphous samples heat treated at temperatures slightly exceeding the glass transition temperature of virgin material. Wide angle X‐ray scattering analysis has confirmed the structural analogies between samples CO 2 crystallized at 50°C and thermally crystallized slightly above T g . A differential scanning calorimeter capable of working at high pressure of CO 2 has been adopted in order to examine the effect of carbon dioxide on the crystallization temperature range.
West Nile Virus Infection Induces Interferon Signalling in Human Retinal Pigment Epithelial Cells (2006)

In this study, the first cell culture model of ophthalmic WNV infection was developed and characterized in RPE cells, and the molecular mechanisms of WNV infection were studied. The data suggest that WNV induces a general antiviral state in RPE cells. This general antiviral state correlates with WNV-induced IFN signaling in retinal cells.
Charles Darwin y la crisis ambiental (2008)

A partir de la pregunta: ?que habria pensado Darwin de la situacion ambiental actual?, el autor reflexiona sobre las crisis ecologicas, los aspectos eticos que rodean los retos ambientales globales y el hecho de que las ensenanzas sobre como somos y de donde venimos de Darwin son una fuente de inspiracion y un referente para construir el futuro.
The multifunctional role of the immunohistochemical expression of MMP‐7 in invasive breast cancer (2005)

The secretion of matrix metalloproteinases (MMPs) is crucial in the metastasis of cancer cells, since MMPs are responsible for the degradation of extracellular matrix (ECM). Among them, matrix metalloproteinase-7 (MMP-7) or matrilysin 1 is a stromelysin which degrades type-IV collagen, fibronectin and laminin. Immunohistochemistry was performed to detect MMP-7 protein in infiltrative breast carcinomas. MMP-7 was studied along with clinicopathological parameters, disease-free and overall survival, and p53, c-erbB-2, topoIIa, MMP-2, uPAR and beta-catenin. MMP-7 immunoreactivity was detected in the cytoplasm of cancer cells in 54.2% (96/177) and tumor stromal cells in 47.5% (84/177), as well as in normal epithelium adjacent to malignant epithelium. MMP-7 reactivity in cancer cells displayed an inverse association with nuclear grade (p=0.049) and topoIIa (p=0.03). A parallel association was observed between the expression of MMP-7 in both malignant and stromal cells with uPAR in cancer cells (p=0.033 and p=0.027, respectively). MMP-7 of tumor stromal cells depicted a parallel correlation with MMP-2 of the same cell type (p=0.044), while abnormal beta-catenin expression was inversely associated with MMP-7 of cancer cells (p=0.047). Our results show the multifunctional role of MMP-7 in the mammary gland, since it seems to be associated with a less aggressive phenotype, while, at the same time, being involved in invasion, through its collaboration with indicators of invasion.
Effect of Reduced Enrichment on the Fuel Cycle for Research Reactors (1982)

The new fuels developed by the RERTR Program and by other international programs for application in research reactors with reduced uranium enrichment (<20% EU) are discussed. It is shown that these fuels, combined with proper fuel-element design and fuel-management strategies, can provide at least the same core residence time as high-enrichment fuels in current use, and can frequently significantly extend it. The effect of enrichment reduction on other components of the research reactor fuel cycle, such as uranium and enrichment requirements, fuel fabrication, fuel shipment, and reprocessing are also briefly discussed with their economic implications. From a systematic comparison of HEU and LEU cores for the same reference research reactor, it is concluded that the new fuels have a potential for reducing the research reactor fuel cycle costs while reducing, at the same time, the uranium enrichment of the fuel.
Strong critical current density enhancement in NiCu/NbN superconducting nanostripes for optical detection (2010)

We present measurements of ferromagnet/superconductor (NiCu/NbN) and plain superconducting (NbN) nanostripes with the linewidth ranging from 150 to 300 nm. The NiCu (3 nm)/NbN (8 nm) bilayers, as compared to NbN (8 nm), showed a up to six times increase in their critical current density, reaching at 4.2 K the values of 5.5 MA/cm2 for a 150 nm wide nanostripe meander and 12.1 MA/cm2 for a 300 nm one. We also observed six-time sensitivity enhancement when the 150 nm wide NiCu/NbN nanostripe was used as an optical detector. The strong critical current enhancement is explained by the vortex pinning strength and density increase in NiCu/NbN bilayers and confirmed by approximately tenfold increase in the vortex polarizability factor.
On interconnecting and orchestrating components in disaggregated data centers: The dReDBox project vision (2016)

Computing systems servers -low- or high-end ones have been traditionally designed and built using a main-board and its hardware components as a “hard” monolithic building block; this formed the base unit on which the system hardware and software stack design build upon. This hard deployment and management border on compute, memory, network and storage resources is either fixed or quite limited in expandability during design time and in practice remains so throughout machine lifetime as subsystem upgrades are seldomely employed. The impact of this rigidity has well known ramifications in terms of lower system resource utilization, costly upgrade cycles and degraded energy proportionality. In the dReDBox project we take on the challenge of breaking the server boundaries through materialization of the concept of disaggregation. The basic idea of the dReDBox architecture is to use a core of high-speed, low-latency opto-electronic fabric that will bring physically distant components more closely in terms of latency and bandwidth. We envision a powerful software-defined control plane that will match the flexibility of the system to the resource needs of the applications (or VMs) running in the system. Together the hardware, interconnect, and software architectures will enable the creation of a modular, vertically-integrated system that will form a datacenter-in-a-box.
Demand-Based Thiolate Anion Generation under Virtually Neutral Conditions:  Influence of Steric and Electronic Factors on Chemo- and Regioselective Cleavage of Aryl Alkyl Ethers (2002)

Thiolate anions have been generated in a "demand-based" fashion under virtually neutral conditions for chemoselective deprotection of aryl alkyl ethers. Solvents play the critical role in making the reaction effective and should have high values of epsilon (>30), molecular polarizabilities (>10), and DN (>27) and low values of AN (<14). However, it is the combined effect of all of these physical properties that make a particular solvent effective. The reaction rates of cleavage of various aryl alkyl ethers are dependent on the steric crowding around the O-alkyl carbon and follow the order propargyl approximately allyl approximately benzyl > methyl > ethyl. Electron-withdrawing substituents increase the rate of ether cleavage reaction. The influence of the steric and electronic factors have been successfully exploited for selective deprotection of aryl alkyl ethers during inter- and intramolecular competitions.

Methods to Improve Old Results of Punch Hair Grafting (1983)

The author describes two new techniques for improving results in previous punch hair grafting patients. The first one enables reharvesting of punch hair grafts from previously maximally used donor scalp. The grafts are cut in two or three rows and the scars from the previous harvesting in between are excised. The thus created continuous donor defect is closed in two layers. The second one in the retransplantation of grafts previously transplanted to bald scalp with enough laxity to be reduced by serial scalp reduction. These two techniques make it possible to improve the results of the "old" punch hair grafting patients almost to the level they would achieve if they started with their surgical hair reconstruction today with the newest techniques of punch graft harvesting and scalp reduction.
Single Shot Dual-Frequency Structured Light Based Depth Sensing (2015)

Structured light techniques are widely used for depth sensing. In this paper, we propose a single shot dual-frequency structured light based method to achieve dense depth in dynamic scenes. The projected pattern is a mixture of two different periodical waves whose phases are related to the change of color and intensity respectively, which can avoid the requirement of Fourier spectra separation in other multi-frequency patterns. Gabor filter is adopted to interpolate the phases. The number theory is used to deal with the phase ambiguity in phase based method conveniently and speedily. A dense depth can be achieved because of the phase-based encoding mode. The proposed method is suitable for dense depth acquisition of the moving object. Experimental results show higher accuracy of the proposed method in depth acquisition compared with the Kinect and larger resolution compared with the ToF (Time of Flight) depth camera. Meanwhile, the proposed method can also acquire the depth of the color scenes and is robust to the surface texture of objects.
Homology and the Optimization of DNA Sequence Data (2001)

Three methods of nucleotide character analysis are discussed. Their implications for molecular sequence homology and phylogenetic analysis are compared. The criterion of inter‐data set congruence, both character based and topological, are applied to two data sets to elucidate and potentially discriminate among these parsimony‐based ideas.
Pharmacologic strategies to reduce cardiovascular disease in type 2 diabetes mellitus: focus on SGLT‐2 inhibitors and GLP‐1 receptor agonists (2019)

Patients with type 2 diabetes mellitus (T2D) present an increased risk for cardiovascular (CV) complications. In addition to improvement in glycaemic control, glucose-lowering therapies, such as glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-dependent glucose cotransporter (SGLT)-2 inhibitors, have been shown to significantly reduce CV events. In 2008, the US Food and Drug Administration mandated that all new glucose-lowering drugs undergo CV outcomes trials (CVOTs) to determine their CV safety. These trials have largely demonstrated no major CV safety concerns. Most notably, the GLP-1RAs and SGLT-2 inhibitors have been found to be not only safe, but also cardioprotective compared to placebo. The SGLT-2 inhibitors have opened a new perspective for clinicians treating patients with T2D and established CV disease in light of their 'pleiotropic' effects, specifically on heart failure, while GLP-1RAs seem to present more favourable effects on atherosclerotic events. In this review, we discuss the role of GLP-1RAs and SGLT-2 inhibitors to reduce CV risk in T2D patients and suggest an individualized therapeutic approach in this population based on the presence of metabolic and CV comorbidities.
Monte Carlo modelling of a‐Si EPID response: The effect of spectral variations with field size and position (2006)

This study focused on predicting the electronic portal imaging device (EPID) image of intensity modulated radiation treatment (IMRT) fields in the absence of attenuation material in the beam with Monte Carlo methods. As IMRT treatments consist of a series of segments of various sizes that are not always delivered on the central axis, large spectral variations may be observed between the segments. The effect of these spectral variations on the EPID response was studied with fields of various sizes and off‐axis positions. A detailed description of the EPID was implemented in a Monte Carlo model. The EPID model was validated by comparing the EPID output factors for field sizes between and at the isocenter. The Monte Carlo simulations agreed with the measurements to within 1.5%. The Monte Carlo model succeeded in predicting the EPID response at the center of the fields of various sizes and offsets to within 1% of the measurements. Large variations (up to 29%) of the EPID response were observed between the various offsets. The EPID response increased with field size and with field offset for most cases. The Monte Carlo model was then used to predict the image of a simple test IMRT field delivered on the beam axis and with an offset. A variation of EPID response up to 28% was found between the on‐ and off‐axis delivery. Finally, two clinical IMRT fields were simulated and compared to the measurements. For all IMRT fields, simulations and measurements agreed within 3%— for 98% of the pixels. The spectral variations were quantified by extracting from the spectra at the center of the fields the total photon yield , the photon yield below , and the percentage of photons below . For the studied cases, a correlation was shown between the EPID response variation and , , and .
Hardware Trojans hidden in RTL don't cares — Automated insertion and prevention methodologies (2015)

Don't cares in RTL code have long plagued chip verification due to hard-to-diagnose “X-bugs” resulting from ambiguous X simulation semantics, yet prevail in modern designs because of enormous opportunities for area/performance/power optimization during synthesis. We analyze don't cares specified at the RTL level from a security perspective and propose a novel class of Hardware Trojans which leak internal circuit node values using only existing design don't cares. Detection of this Trojan class is impossible using either functional simulation/verification or a perfect sequential equivalence checker. We then provide a formal automated X-analysis technique which both prevents the insertion of this new Trojan type and also has the potential to uncover accidental X-bugs as well. We provide several examples, including an Elliptic Curve Processor, illustrating both Trojan insertion and our prevention technique.
