On the Reconstruction of Face Images from Deep Face Templates (2018)

State-of-the-art face recognition systems are based on deep (convolutional) neural networks. Therefore, it is imperative to determine to what extent face templates derived from deep networks can be inverted to obtain the original face image. In this paper, we study the vulnerabilities of a state-of-the-art face recognition system based on template reconstruction attack. We propose a neighborly de-convolutional neural network (NbNet) to reconstruct face images from their deep templates. In our experiments, we assumed that no knowledge about the target subject and the deep network are available. To train the NbNet reconstruction models, we augmented two benchmark face datasets (VGG-Face and Multi-PIE) with a large collection of images synthesized using a face generator. The proposed reconstruction was evaluated using type-I (comparing the reconstructed images against the original face images used to generate the deep template) and type-II (comparing the reconstructed images against a different face image of the same subject) attacks. Given the images reconstructed from NbNets, we show that for verification, we achieve TAR of 95.20 percent (58.05 percent) on LFW under type-I (type-II) attacks @ FAR of 0.1 percent. Besides, 96.58 percent (92.84 percent) of the images reconstructed from templates of partition fa (fb) can be identified from partition fa in color FERET. Our study demonstrates the need to secure deep templates in face recognition systems.
Design of 60GHz Millimetre-Wave Integrated SIR-MH Microstrip Bandpass Filters on Bulk CMOS (2008)

In this paper challenges of integrating millimetre-wave bandpass filters on CMOS are discussed. A new compact 57-66GHz 4th-order cross-coupled SIR-MH bandpass filter was designed and fabricated on 0.13μm bulk CMOS. Both simulation and measurement results are presented. The measurement results show 8.5GHz bandwidth from 58-66.5GHz, 5.9dB insertion loss, and better than 10dB return loss over the whole passband. The filter reported in this paper has higher selectivity and is 80 percent smaller than other designs reported in the literature. This paper demonstrates the feasibility of building compact millimetre-wave integrated bandpass filters on CMOS.
Graphene synthesis by chemical vapor deposition and transfer by a\n roll-to-roll process (2010)

We synthesized centimeter-scale single- to few-layer graphene (FLG) films via\nchemical vapor deposition (CVD) on Ni foils. We demonstrates that the\nprecipitation mechanism may not be the only important mechanism in the\nformation of graphene by CVD in Ni system, and that controlling the cooling\nrate in the CVD process may not be the appropriate way to control the thickness\nof graphene films. In addition, we are the first to demonstrate the transfer of\ncentimeter-scale FLG from Ni foil to transparent flexible polyethylene\nterephthalate substrates via an efficient roll-to-roll process. Comparing to\nrigid substrates, synthesis of graphene on flexible Ni foil has necessity for\nthe use of a roll-to-roll transfer process.\n
Create Connections between Audiovisual and Finance (2014)

The finance of the audiovisual industry is essentially self-referential; therefore intermediaries and financial markets have a small influence. The chapter provides an insight on the explanations to the distance between the audiovisual industry and financial markets, considering both the perspective of audiovisual companies and financial intermediaries. It also analyses which reasons call for a deeper connection between audiovisual and financial industry and which requirements should be fulfilled to create a profitable and long-lasting interaction between audiovisual and financial markets.
Methionine Sulfoxide Reductases (2006)

Proteins are subject to modification by reactive oxygen species (ROS), and oxidation of specific amino acid residues can impair their biological function, leading to an alteration in cellular homeostasis. Methionine is among the amino acids the most susceptible to oxidation by almost all forms of ROS, resulting in both S and R diasteroisomeric forms of methionine sulfoxide. These modifications can be repaired specifically by the peptide methionine sulfoxide reductase A and B enzymes (MsrA and MsrB), respectively. MsrA has been detected in several organisms going from prokaryotes to eukaryotes. MsrA is tightly implicated in protection against oxidative stress and in protein maintenance, which is critical in the aging process. Several studies have shown that overexpression of MsrA led to an increased resistance against oxidative stress, while MsrA null mutants are more sensitive toward oxidative stress. Since oxidative damage is a key factor in aging, overexpression of MsrA in some organisms led to an increased life span whereas deletion of the gene led to the opposite. MsrA could also be involved, by regulating the function and/or expression of target proteins, in ROS-mediated signal transduction. In fact, changes in gene expression, including certain oxidative stress-response genes, have been observed when MsrA is overexpressed. This review elaborates on the current knowledge in the implication of the Msr system in protection against oxidative stress and aging.
Glycosaminoglycan-based biomaterials for growth factor and cytokine delivery: Making the right choices (2019)

Controlled, localized drug delivery is a long-standing goal of medical research, realization of which could reduce the harmful side-effects of drugs and allow more effective treatment of wounds, cancers, organ damage and other diseases. This is particularly the case for protein "drugs" and other therapeutic biological cargoes, which can be challenging to deliver effectively by conventional systemic administration. However, developing biocompatible materials that can sequester large quantities of protein and release them in a sustained and controlled manner has proven challenging. Glycosaminoglycans (GAGs) represent a promising class of bio-derived materials that possess these key properties and can additionally potentially enhance the biological effects of the delivered protein. They are a diverse group of linear polysaccharides with varied functionalities and suitabilities for different cargoes. However, most investigations so far have focused on a relatively small subset of GAGs - particularly heparin, a readily available, promiscuously-binding GAG. There is emerging evidence that for many applications other GAGs are in fact more suitable for regulated and sustained delivery. In this review, we aim to illuminate the beneficial properties of various GAGs with reference to specific protein cargoes, and to provide guidelines for informed choice of GAGs for therapeutic applications.
Performance of the SCI ring (1992)

The Scalable Coherent Interface (SCI) is an emerging IEEE standard that provides computer-bus-like services to a set of nodes via fast, unidirectional links. This paper presents the first detailed performance study of the SCI ring, using both analytical models and simulation. Performance is analyzed for uniform and nonuniform traffic, and the effect of the ring's flow control protocol is studied. The queueing model is based on an M/G/1 queue, augmented to include the effect of packet trains on the mean and variance of the source transmission time. The model is validated against simulation results, and shown to be quantitatively accurate for uniform workloads, and at least qualitatively accurate for nonuniform workloads. The flow control mechanism is shown to effectively prevent node starvation and reduce the ability of nodes to unfairly consume ring bandwidth, but at the cost of decreased overall ring utilization. The SCI ring is also compared to a standard bus, modeled with a simple M/G/1 queue, and shown to provide substantially higher throughputs and lower latency than a bus with realistic clock speeds.
Comparison of Cl2 and F2 based chemistries for the inductively coupled plasma etching of NiMnSb thin films (1999)

Plasma etching chemistries based on BCl3/Ar, BCl3/H2 and NF3/Ar were studied for patterning NiMnSb Heusler alloys thin films and associated Al2O3 barrier layers in an inductively coupled plasma tool. Using BCl3/Ar discharges, high etch rates (⩾1 μm/min) were achieved either at high source power [(1000 W) or high direct current (dc) self bias (−300 V)] and etch rates showed a strong dependence upon source power, ion energy, and gas composition. Hydrogen addition to the BCl3 created new species (HCl) in the plasma, leading to faster etch rates for NiMnSb than in the case of Ar addition. Selectivities of ⩾8 for NiMnSb over Al2O3 were obtained in BCl3-based discharges. On the other hand, NF3/Ar discharges provided a narrow process window for the etching of NiMnSb and the etch rates were much lower compared to those with BCl3. The surfaces of NiMnSb etched with NF3/Ar was smoother (root-mean-square surface roughness of 1.4 nm measured by atomic force microscopy) than the surfaces produced with BCl3/Ar. In terms of near-surface chemistry, NF3/Ar produced Mn enrichment, indicating the existence of involatile Mn etch products, whereas Mn deficiency was obtained under the same conditions with BCl3/Ar.
REPRODUCTION ON THE RANCH (2003)

It is generally acknowledged that reproductive parameters are the most important components of a profitable beef operation. Research in beef cattle reproduction has led to a number of management strategies, each of which could improve efficiency of production and profitability. However, to make good decisions regarding applicability of these strategies to a specific operation requires a thorough cost:benefit:feasability analysis. Whether a strategy is appropriate for a given enterprise will be determined by the goals of the owner/manager and the human, animal, land and fiscal resources available. The following are a few of the most important considerations when making decisions regarding management of the reproductive process on a ranch.
Effects of Blade Loading Distribution on Aerodynamic Performance of Ultra-High Lift LP Turbine Airfoils Under the Influences of Wake Passing and Freestream Turbulence (2010)

This paper deals with studies on the flow field around three types of linear cascades of low pressure turbine (LPT) airfoils with different chordwise loading distributions, while keeping the aerodynamic loading index almost the same. The purpose of the low-speed linear cascade study is to clarify the performance of newly designed two ultra high-lift blade (UHL blade) and compare each of them to that of the conventional LPT blade (Base Model) with low solidity through the measurements of boundary layers accompanied by separation bubble for low Reynolds number conditions. Cylindrical bars on the timing belts work as wake generator to emulate upstream stator wakes that impact the boundary layer on the airfoil suction surface. Freestream turbulence is also enhanced by use of passive turbulence grid. In addition to the pneumatic probe measurements of the midspan loss characteristics of each of the cascades, hot-wire probe measurement is conducted over the blade suction surface to understand to what extent and how the interaction of incoming wakes as well as freestream turbulence affect the boundary layer and separation bubble. Computational Fluid Dynamics (CFD) analyses are also applied to the flow fields around the cascades, mainly using Large-Eddy Simulation (LES) with dynamic Smagorinsky subgrid scale model.
Immunogenicity of Haemophilus Influenza and Pneumococcal Vaccines in Related and Unrelated Transplant Recipients. (2006)

Abstract Despite advances in post transplant supportive care, invasive infections due to Haemophilus influenza and pneumococcus continue to result in significant morbidity and mortality long after successful HCT. Introduction of the protein-conjugated vaccines in healthy children has been associated with a reduction in invasive infections due to these organisms. Although current post transplant guidelines recommend immunization with the protein-conjugated H. flu vaccine, they still include the use of the 23-valent pure polysaccharide pneumococcal vaccine (PPV), a poor immunogen even in HLA matched sibling transplant recipients. There is limited data on the immunogenicity of any of these vaccines in recipients of an unrelated or T-cell depleted (TCD) HCT. In this study, we evaluated the responses of 270 allogeneic transplant patients who received the H flu conjugate vaccine and initial pneumococcal vaccination with either the 23-valent PPV (n=156) or a series of the protein-conjugated pneumococcal vaccine, Prevnar (n=114). The median age of the 270 patients at the time of HCT was 25.1 years (range, 0.2–69 years). Thirty-eight percent of the patients were children (&amp;lt;18 years of age). Donors were unrelated, HLA-mis-matched related or HLA matched related in 74, 22, and 174 cases, respectively. Seventy percent of patients underwent a TCD HCT. All vaccines were well tolerated. One child had a reversible allergic response to Prevnar. Eighty-seven percent of the patient population responded to the H flu conjugate vaccine, defined as a ≥3 fold rise in titer or seroconversion. Only 24% of patients responded to the 23-valent PPV. There was no significant difference between the response to PPV administered &amp;lt; or &amp;gt; 24 months post HCT (18% vs 28%, p=0.058), nor between children and adults (19% vs 25%, p=0.16). In contrast, 75% of patients were capable of responding to Prevnar, initiated at a median of 16 months post transplant. Response to Prevnar was significantly better in patients &amp;lt; 18 years of age compared to older individuals (85% vs 56%, respectively, p&amp;lt;0.001). There was no significant difference in the ability of children who received an unrelated or HLA matched related HCT to respond to Prevnar (85% vs 86%, p=0.385). In adults, 48% vs 69%, p=0.132) responded to Prevnar following an HLA-matched related or unrelated HCT, respect ively. Forty-one patients who failed to respond to the 23-valent PPV were subsequently immunized with a series of 3 doses of Prevnar administered 2 months apart, resulting in a 76% response rate. These data suggest that continued inclusion of the 23-valent PPV is inadequately protecting patients against a potentially preventable and often fatal disease. Consideration should be given to utilization of Prevnar in the upfront vaccination of children and adults following allogeneic HCT.

On the binding of Mg2+, Ca2+, Zn2+ and Cu+ metal cations to 2 ′ -deoxyguanosine: Changes on sugar puckering and strength of the -glycosidic bond (2011)

The binding of Mg2+, Ca2+, Zn2+ and Cu+ metal cations to 2′-deoxyguanosine has been analyzed, using the hybrid B3LYP, Density Functional Theory (DFT) method and 6–311++G(d,p) orbital basis sets. Coordination geometries, absolute metal ion affinities, and free energies for the most stable complexes formed by Mg2+, Ca2+, Zn2+ and Cu+ with the nucleoside, 2′-deoxyguanosine, have been determined. Furthermore, the influences of metal cationization on the strength of the N-glycosidic bond, torsion angles and angle of Pseudorotation (P) have been studied. With respect to the results, it has been found that metal binding significantly changes the values of the phase angle of Pseudorotation (P) in the sugar unit of these nucleosides. In all modified forms, the length of the C1′–N9 bond increases. The Mulliken population analysis on atomic charges has been carried out on the optimized geometries. Natural Bond Orbital (NBO) analysis was also performed to calculate the charge transfer and natural population analysis of the complexes. Quantum Theory of Atoms In Molecules (QTAIM) was also applied to determine the nature of interactions.
Virtual routers on the move (2008)

The complexity of network management is widely recognized as one of the biggest challenges facing the Internet today. Point solutions for individual problems further increase system complexity while not addressing the underlying causes. In this paper, we argue that many network-management problems stem from the same root cause---the need to maintain consistency between the physical and logical configuration of the routers. Hence, we propose VROOM (Virtual ROuters On the Move), a new network-management primitive that avoids unnecessary changes to the logical topology by allowing (virtual) routers to freely move from one physical node to another. In addition to simplifying existing network-management tasks like planned maintenance and service deployment, VROOM can also help tackle emerging challenges such as reducing energy consumption. We present the design, implementation, and evaluation of novel migration techniques for virtual routers with either hardware or software data planes. Our evaluation shows that VROOM is transparent to routing protocols and results in no performance impact on the data traffic when a hardware-based data plane is used.

Multi‐Beam and Shaped‐Beam Reflectarray Antennas (2018)

This chapter presents a systematic study on various design methods of multi-beam and shaped-beam reflectarray antennas. It describes direct design methods for multi-beam reflectarrays, the geometrical method and the superposition method. The chapter demonstrates that although both methods can generate a multi-beam radiation pattern, neither approach provides satisfactory performance, mainly due to high side-lobe levels and gain loss in these designs. It introduces synthesis design techniques, and two different optimization techniques, the alternating projection method and the particle swarm optimization method, are then implemented to optimize the phase distribution on the reflectarray surface. The chapter also presents several examples of shaped and multi-beam reflectarray antennas. Reflectarrays can generate single or multiple pencil- or shaped beams with single or multiple feeds, and several designs have been presented over the years. In addition to the multiple beam designs introduced earlier that use a single-feed antenna, reflectarrays can also achieve a multi-beam performance by using multiple feed antennas.

Modulation Classification of MIMO-OFDM Signals by Independent Component Analysis and Support Vector Machines (2013)

A modulation classification (MC) scheme based on Independent Component Analysis (ICA) in conjunction with either maximum likelihood (ML) or Support Vector Machines (SVM) is proposed for MIMO-OFDM signals over frequency selective, time varying channels. The method is blind in the sense that it is assumed that the receiver has no information about the channel and transmitted signals other than that the spatial streams of signals are statistically independent. The processing consists of separation of the MIMO streams followed by modulation classification of the separated signals. While in general, blind separation of signals over frequency selective channels is a difficult problem, the non-frequency selective nature of the channel experienced by individual symbols in a MIMO-OFDM system enables the application of well-known ICA algorithms. Modulation classification is implemented by maximum likelihood and by an SVM-based modulation classification method relying on pre-selected modulation-dependent features. To improve performance in time varying channels, the invariance of the channel is exploited across the coherence bandwidth and the time coherence. The proposed method is shown to perform with high probability of correct classification over realistic ITU pedestrian and vehicular channels. An upper bound on the probability of correct classification is developed based on the Cramer Rao bound of channel estimation.

H3K36 Methylation Regulates Nutrient Stress Response in Saccharomyces cerevisiae by Enforcing Transcriptional Fidelity (2017)

Set2-mediated histone methylation at H3K36 regulates diverse activities, including DNA repair, mRNA splicing, and suppression of inappropriate (cryptic) transcription. Although failure of Set2 to suppress cryptic transcription has been linked to decreased lifespan, the extent to which cryptic transcription influences other cellular functions is poorly understood. Here, we uncover a role for H3K36 methylation in the regulation of the nutrient stress response pathway. We found that the transcriptional response to nutrient stress was dysregulated in SET2-deleted (set2Δ) cells and was correlated with genome-wide bi-directional cryptic transcription that originated from within gene bodies. Antisense transcripts arising from these cryptic events extended into the promoters of the genes from which they arose and were associated with decreased sense transcription under nutrient stress conditions. These results suggest that Set2-enforced transcriptional fidelity is critical to the proper regulation of inducible and highly regulated transcription programs.
Durability of Resistance in Tomato and Pepper to Xanthomonads Causing Bacterial Spot (2009)

Both hypersensitive and quantitative forms of resistance to the bacterial spot pathogens (Xanthomonas spp.) occur in pepper and tomato. Five resistance genes involved in hypersensitivity in pepper and four in tomato have been identified so far. The corresponding pathogen avirulence genes have been cloned and characterized, and features, including a propensity for accumulating mutations and at times, loss of plasmid-borne avirulence genes, are known to occur. The frequency of these changes affects race composition among pathogen populations and determines the durability of the corresponding plant resistance. At least four different species of Xanthomonas are known to cause bacterial spot, and these can differ in specific avirulence gene content. Quantitative or multigenic resistance has also more recently been researched and appears to be more durable than the hypersensitive resistance. Two recessive genes have been identified that yield a nonhypersensitive form of resistance in pepper and together can provide strong resistance. More emphasis is being given to transfer of quantitative trait resistance to commercial cultivars of both tomato and pepper.
