VPN Protection with QKD-Derived Keys Using Standard Interfaces (2023)

Quantum Key Distribution is a mechanism for obtaining a symmetric key that has been proved to be completely secure against quantum attacks. However, QKD technology is highly dependent on the low level implementation of the vendor. This work proposes the use of QKD-derived key material using high level standard interfaces to transparently protect services based on extending the protection of Virtual Private Networks to possible attacks based on quantum computing.
Statistical learning based facial animation (2013)

To synthesize real-time and realistic facial animation, we present an effective algorithm which combines image- and geometry-based methods for facial animation simulation. Considering the numerous motion units in the expression coding system, we present a novel simplified motion unit based on the basic facial expression, and construct the corresponding basic action for a head model. As image features are difficult to obtain using the performance driven method, we develop an automatic image feature recognition method based on statistical learning, and an expression image semi-automatic labeling method with rotation invariant face detection, which can improve the accuracy and efficiency of expression feature identification and training. After facial animation redirection, each basic action weight needs to be computed and mapped automatically. We apply the blend shape method to construct and train the corresponding expression database according to each basic action, and adopt the least squares method to compute the corresponding control parameters for facial animation. Moreover, there is a pre-integration of diffuse light distribution and specular light distribution based on the physical method, to improve the plausibility and efficiency of facial rendering. Our work provides a simplification of the facial motion unit, an optimization of the statistical training process and recognition process for facial animation, solves the expression parameters, and simulates the subsurface scattering effect in real time. Experimental results indicate that our method is effective and efficient, and suitable for computer animation and interactive applications.

A wavelength-routing node using multifunctional semiconductor optical amplifiers and multiple-pilot-tone-coded subcarrier control headers (1997)

We demonstrate wavelength routing by using the control information encoded in a multiple-pilot-tone subcarrier header. Header detection, header removal, packet gating and wavelength shifting are all performed by a single multifunctional semiconductor optical amplifier (SOA). Based on the header information contained in the 60-ns-long pilot tones, each incoming 1-Gb/s data packet either: (1) passes through the switch unaffected or (2) is wavelength shifted and dropped at the switch.
Impact of Interface Mixing on the Performance of Solution Processed Organic Light Emitting Diodes—Impedance and Ultraviolet Photoelectron Spectroscopy Study (2017)

We investigated interfacial mixing of solution-processed organic light-emitting devices (OLEDs) using impedance spectroscopy (IS) and ultraviolet photoelectron spectroscopy (UPS) and its impact on device performance. We focused on interfacial mixing between a solution-processed cross-linkable hole transport layer (XM) and an emitting layer (EML), formed either by solution processing or vacuum evaporation. The results of IS and UPS clearly indicated that extensive interfacial mixing was unavoidable, even after the XM was cross-linked to make it insoluble and rinsed to remove residual soluble species, if the subsequent EML was solution processed. In addition, we also demonstrated that interfacial mixing indeed increased hole current density in corresponding hole only device (HOD). In fact, the hole injection efficiency could be an order of magnitude better when the EML was solution processed rather than vacuum evaporated. We investigated such behavior to find the desirable process condition of solution-processed OLEDs.

Parallel programming for the web (2012)

Parallel hardware is today's reality and language extensions that ease exploiting its promised performance flourish. For most mainstream languages, one or more tailored solutions exist that address the specific needs of the language to access parallel hardware. Yet, one widely used language is still stuck in the sequential past: JavaScript, the lingua franca of the web.Our position is that existing solutions do not transfer well to the world of JavaScript due to differences in programming models, the additional requirements of the web, like safety, and to developer expectations. To address this we propose River Trail, a new parallel programming API designed specifically for JavaScript and we show how it satisfies the needs of the web. To prove that our approach is viable, we have implemented a prototype JIT compiler in Fire-fox that shows an order of magnitude performance improvement for a realistic web application.
Measurements of observables sensitive to colour reconnection in $$t{\bar{t}}$$ events with the ATLAS detector at $$\sqrt{s} =$$ 13 TeV (2023)

Abstract A measurement of observables sensitive to effects of colour reconnection in top-quark pair-production events is presented using 139 $$\hbox {fb}^{-1}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msup> <mml:mtext>fb</mml:mtext> <mml:mrow> <mml:mo>-</mml:mo> <mml:mn>1</mml:mn> </mml:mrow> </mml:msup> </mml:math> of 13 TeV proton–proton collision data collected by the ATLAS detector at the LHC. Events are selected by requiring exactly one isolated electron and one isolated muon with opposite charge and two or three jets, where exactly two jets are required to be b -tagged. For the selected events, measurements are presented for the charged-particle multiplicity, the scalar sum of the transverse momenta of the charged particles, and the same scalar sum in bins of charged-particle multiplicity. These observables are unfolded to the stable-particle level, thereby correcting for migration effects due to finite detector resolution, acceptance and efficiency effects. The particle-level measurements are compared with different colour reconnection models in Monte Carlo generators. These measurements disfavour some of the colour reconnection models and provide inputs to future optimisation of the parameters in Monte Carlo generators.
Sterilization of polypropylene membranes of facepiece respirators by ionizing radiation (2020)

Ionizing radiation has been identified as an option for sterilization of disposable filtering facepiece respirators in situations where the production of the respirators cannot keep up with demand. Gamma radiation and high energy electrons penetrate deeply into the material and can be used to sterilize large batches of masks within a short time period. In relation to reports that sterilization by ionizing radiation reduces filtration efficiency of polypropylene membrane filters on account of static charge loss, we have demonstrated that both gamma and electron beam irradiation can be used for sterilization, provided that the respirators are recharged afterwards.
The governance of personal data for COVID-19 response: perspective from the Access to COVID-19 Tools Accelerator (2021)

COVID-19 is the world’s first digital pandemic. Digital tools and technologies have been developed to track and trace the spread of the virus, screen for infection, and the pandemic has accelerated the use of digital technology in the delivery of healthcare. The continued development of these tools and technologies, the monitoring of the virus and the development of new tests, treatments and vaccines are dependent on the collection of and access to vast amounts of personal data. This includes clinical data, epidemiological data and public health data that may be collected from laboratories, medical records, wearables and smartphone apps. Previous public health emergencies (PHEs) have demonstrated the importance in making this data available, and early in the COVID-19 pandemic, there were calls for making all kinds of data, including clinical trial data, routine surveillance data, genetic sequencing, and data on the ongoing monitoring of disease control programmes, openly and rapidly available. As part of this, personal data on age, race, sex, health, ethnic group, and socioeconomic factors have been shared. This has helped led to the rapid development of COVID-19 interventions. It has also enabled the better understanding of factors contributing to difference in infection rates and effectiveness of tests, treatments, and vaccines. However, the use of this particularly sensitive data can infringe upon individual and group privacy, increase the risks of individual and group stigma and discrimination, and it may negatively impact already vulnerable, marginalised or minority populations.

Cognitive Radio-Inspired Rate-Splitting Multiple Access for Semi-Grant-Free Transmissions (2022)

In this paper, we propose a cognitive radio-inspired rate-splitting multiple access (CR-RSMA) scheme to assist semi-grant-free (SGF) transmissions in which a grant-based user (GBU) and multiple grant-free users (GFUs) access the base-station (BS) by sharing the same resource block. Using the cognitive radio principle, the GBU and admitted GFU are treated as the primary and secondary users, respectively, and rate-splitting is applied at the admitted GFU to realize SGF transmissions. The admitted GFU's transmit power allocation, target rate allocation, and successive interference cancellation decoding order at the BS are jointly optimized to attain the maximum achievable rate for the admitted GFU without deteriorating the GBU's outage performance compared to orthogonal multiple access. Due to the extended non-outage zone, CR-RSMA-assised SGF (CR-RSMA-SGF) transmissions achieve a lower outage probability than SGF transmissions assisted by cognitive radio-inspired non-orthogonal multiple access. Exact expressions and asymptotic analysis for the admitted GFU's outage probability are derived to evaluate the system performance achieved by CR-RSMA-SGF transmissions. The superior outage performance and full multiuser diversity gain achieved by CR-RSMA-SGF transmissions are verified by the analytical and simulation results.
On the Optimal Predictive Control Algorithm for Comfort-Oriented Semi-Active Suspensions (2004)

&lt;div class="htmlview paragraph"&gt;The problem considered in this paper is the design and analysis of the optimal control strategy for comfort-oriented semi-active suspensions in road vehicles. The goal of this work is to study and analyze the best control algorithm, and to use it as a benchmark. It is shown that the best control algorithm is an on-off switching strategy, which is designed using the principles of optimal and predictive control, under the assumption that the road disturbance can be predicted over a short time-horizon. Even though this optimal control strategy can be computationally intensive in a real-time application, it sets a lower bound on the best possible attenuation performance achievable by semi-active damping control.&lt;/div&gt;
Syntheses of Molybdenum and Tungsten Imido Alkylidene Complexes that Contain a Bidentate Oxo/Thiolato Ligand (2020)

Abstract 3,3′,5,5′‐Tetra‐ tert ‐butyl‐2′‐sulfanyl[1,1′‐biphenyl]‐2‐ol (H 2 [ t Bu 4 OS]) was prepared in 24 % yield overall from the analogous biphenol using standard techniques. Addition of H 2 [ t Bu 4 OS] to Mo(NAr)(CHCMe 2 Ph)(2,5‐dimethylpyrrolide) 2 led to formation of Mo(NAr)(CHCMe 2 Ph)[ t Bu 4 OS], which was trapped with PMe 3 to give Mo(NAr)(CHCMe 2 Ph)[ t Bu 4 OS](PMe 3 ) ( 1 (PMe 3 )). An X‐ray crystallographic study of 1 (PMe 3 ) revealed that two structurally distinct square pyramidal molecules are present in which the alkylidene ligand occupies the apical position in each. Both 1 (PMe 3 ) A and 1 (PMe 3 ) B are disordered. Mo(NAd)(CHCMe 2 Ph)( t Bu 4 OS)(PMe 3 ) ( 2 (PMe 3 ); Ad=1‐adamantyl) and W(NAr)(CHCMe 2 Ph)( t Bu 4 OS)(PMe 3 ) ( 3 (PMe 3 )) were prepared using analogous approaches. 1 (PMe 3 ) reacts with ethylene (1 atm) in benzene within 45 minutes to give an ethylene complex Mo(NAr)( t Bu 4 OS)(C 2 H 4 ) ( 4 ) that is isolable and relatively stable toward loss of ethylene below 60 °C. An X‐ray study shows that the bond distances and angles for the ethylene ligand in 4 are like those found for bisalkoxide ethylene complexes of the same general type. Complex 1 (PMe 3 ) in the presence of one equivalent of B(C 6 F 5 ) 3 catalyzes the homocoupling of 1‐decene, allyltrimethylsilane, and allylboronic acid pinacol ester at ambient temperature. 1 (PMe 3 ), 2 (PMe 3 ), and 3 (PMe 3 ) all catalyze the ROMP of rac ‐ endo , exo ‐5,6‐dicarbomethoxynorbornene ( rac ‐DCMNBE) in the presence of B(C 6 F 5 ) 3 , but the polyDCMNBE that is formed has a random structure.
Epicardial catheter-based ventricular reconstruction: a novel therapy for ischaemic heart failure with anteroapical aneurysm (2013)

OBJECTIVES: Surgical ventricular reconstruction has been used to treat ischaemic cardiomyopathy with large akinetic or dyskinetic areas. However, application of this approach requires a sternotomy, cardiopulmonary bypass and a left ventriculotomy. This study assessed the feasibility and efficacy of minimally invasive, off-pump, epicardial catheter-based ventricular reconstruction (ECVR) in an anteroapical aneurysm ovine model.
Evolutionary history of human Plasmodium vivax revealed by genome-wide analyses of related ape parasites (2018)

Wild-living African apes are endemically infected with parasites that are closely related to human <i>Plasmodium vivax</i>, a leading cause of malaria outside Africa. This finding suggests that the origin of <i>P. vivax</i> was in Africa, even though the parasite is now rare in humans there. To elucidate the emergence of human <i>P. vivax</i> and its relationship to the ape parasites, we analyzed genome sequence data of <i>P. vivax</i> strains infecting six chimpanzees and one gorilla from Cameroon, Gabon, and Côte d'Ivoire. We found that ape and human parasites share nearly identical core genomes, differing by only 2% of coding sequences. However, compared with the ape parasites, human strains of <i>P. vivax</i> exhibit about 10-fold less diversity and have a relative excess of nonsynonymous nucleotide polymorphisms, with site-frequency spectra suggesting they are subject to greatly relaxed purifying selection. These data suggest that human <i>P. vivax</i> has undergone an extreme bottleneck, followed by rapid population expansion. Investigating potential host-specificity determinants, we found that ape <i>P. vivax</i> parasites encode intact orthologs of three reticulocyte-binding protein genes (<i>rbp2d</i>, <i>rbp2e</i>, and <i>rbp3</i>), which are pseudogenes in all human <i>P. vivax</i> strains. However, binding studies of recombinant RBP2e and RBP3 proteins to human, chimpanzee, and gorilla erythrocytes revealed no evidence of host-specific barriers to red blood cell invasion. These data suggest that, from an ancient stock of <i>P. vivax</i> parasites capable of infecting both humans and apes, a severely bottlenecked lineage emerged out of Africa and underwent rapid population growth as it spread globally.
Preparation of multi-nanocrystalline transition metal oxide (TiO2–NiTiO3) mesoporous thin films (2004)

Ordered mesoporous TiO2–NiTiO3 thin films, with nickel content x < 0.5, were prepared by dip-coating an acidic solution of hydrolysed transition metal chlorides in controlled humidity, followed by a very careful annealing treatment. These latter treatments were studied by in situ SAXS-WAXS experiments involving synchrotron radiation and TEM analysis. They revealed that the walls can be composed of amorphous, single crystalline or multi crystalline nanoparticles depending on x and the conditions applied during the thermal treatment.

Thin-Oxide Charging Damage to Microelectronic Test Structures in an Electron-Cyclotron-Resonance Plasma (2005)

The purpose of this work is: ~i! to investigate charging damage to polysilicon-gate metal-oxide-semiconductor ~MOS! capacitor antenna test structures upon exposure to O2 plasmas generated in an electron-cyclotron-resonance ~ECR! plasma source; and ~ii! to determine the effect of radial plasma nonuniformities on the charging damage. Previous work with ECR reactors 1‐3 and other types of plasma systems 4‐7 has indicated that nonuniformities in the plasma parameters across the surface of the wafer during processing may play a role in the generation of charging damage. Our goal is to quantify the relationship between the plasma con
Time-domain response of point-defect cavities in two-dimensional photonic crystal slabs using picosecond light pulse (2006)

Time-domain responses of point-defect cavities in two-dimensional photonic crystal slabs are directly investigated. Point-defect cavities are excited by picosecond light pulses and time evolutions of the light emissions are measured by using cross-correlation method. The obtained signals clearly show delays in initial rises and tailings in later stages which reflect photon lifetimes of the cavities. The signals are analyzed by comparing with numerical simulations where Gaussian input pulses and linear responses of the systems are assumed. Photon lifetimes are evaluated to be &amp;lt;1, 3, and 9ps for the point-defect cavities having Q factors of 500, 3800, and 10 000, respectively. We believe that the results obtained here will contribute to the time-domain manipulation of photons utilizing artificial defects in photonic crystals.
The role of chemokines and chemokine receptors in mucosal inflammation (2000)

Chemokines represent a large family of small cytokines, the main function of which is the attraction of leukocytes to different tissues. Several chemokines and their receptors have been shown to play a critical role in lymphoid development, mucosal immunity, and inflammation. In this article we review recent advances in chemokine physiology and their potential role in the pathogenesis of mucosal inflammation. We also discuss the potential for the use of chemokine or chemokine receptor antagonists as novel therapies for inflammatory bowel disease.
Novel nanospring interconnects for high-density applications (2002)

A new cantilevered structure, called the nanospring, is being developed to enable a fine-pitch, high density I/O architecture for the next generation chip and probing technology. This technology meets the requirements of the National Technology Roadmap for Semiconductors (NTRS) for 2012 and beyond. Based on its unique structure, a new contact mode of sliding contact with no solder is being tested. To understand the reliability of the package with this novel compliant structure and the typical behavior of sliding contacts, test vehicles with different orientations of the nanospring (21 /spl mu/m pitch) have been fabricated, assembled and subjected to thermal cycling tests. In-situ resistance and temperature measurements have been conducted.

Optimal User Loading in Massive MIMO Systems with Regularized Zero Forcing Precoding (2016)

We consider a downlink massive multiple-input multiple output system employing regularized zero-forcing precoding. We derive the asymptotic signal-to-leakage-plus-noise ratio (SLNR) as both the number of antennas and the number of users go to infinity at a fixed ratio. Focusing on spatially uncorrelated channels with homogeneous large scale fading gains, we show that the SLNR is asymptotically equal to signal-to-interference-plus-noise ratio, which allows us to optimize the user loading for spectral efficiency. The results show that the optimal user loading varies depending on the channel signal-to-noise ratio (SNR). As the SNR increases, the optimal user loading decreases at low SNR, but increases at high SNR.
Estrogen withdrawal‐induced human breast cancer tumour regression in nude mice is prevented by Bcl‐2 (1998)

We recently showed that estrogen induces expression of the anti‐apoptotic protein, Bcl‐2 in MCF‐7 human breast cancer cells. Since estrogen‐dependent breast tumours can regress following estrogen withdrawal, we hypothesized that stable Bcl‐2 expression would prevent estrogen‐withdrawal induced regression of MCF‐7 tumours. We therefore established tumours in ovariectomized female nude mice implanted with an estrogen‐release pellet using untransfected MCF‐7 cells or MCF‐7 cells stably transfected with a Bcl‐2 cDNA sense or antisense expression vector. All tumours grew at similar rates indicating that Bcl‐2 levels have no effect on tumour formation. After removal of the estrogen pellet, Bcl‐2 antisense tumours and untransfected MCF‐7 tumours regressed means of 49% and 52%, respectively, after estrogen pellet removal whereas Bcl‐2 sense tumours were significantly stabilized. Regressing tumours displayed characteristics of apoptotic cells. These results show that Bcl‐2 can prevent hormone‐dependent breast tumour regression and are consistent with the notion that decreased Bcl‐2 levels following estrogen withdrawal renders hormone‐dependent breast tumour cells sensitive to apoptotic regression.
