Directed Assembly of Optoplasmonic Hybrid Materials with Tunable Photonic–Plasmonic Properties (2015)

Optoplasmonic materials are metallo-dielectric hybrid structures that combine metallic and dielectric components in defined geometries in which plasmonic and photonic modes synergistically interact. These beneficial interactions can be harnessed by integrating plasmonic nanoantennas into defined photonic environments generated, for instance, by discrete optical resonators or extended systems of diffractively coupled nanoparticles. Optoplasmonic structures facilitate photonic-plasmonic mode coupling and offer degrees of freedom for creating optical fields with predefined amplitude and phase in space and time that are absent in conventional photonic or plasmonic structures. This Perspective reviews the fundamental electromagnetic mechanisms underlying selected optoplasmonic approaches with an emphasis on materials available through template-guided self-assembly strategies.
Immobilization of Pu-containing wastes into glass and ceramics: Results of US-Russia collaboration (2000)

This continuing collaboration between the V.G. Khlopin Radium Institute (KRI) in St. Petersberg, Russia, and Lawrence Livermore National Laboratory (LLNL) in the United States was initiated in 1997. The collaboration is focused on plutonium immobilization to support the disposition of excess weapons plutonium in the US and Russia. Our work consists primarily of laboratory-scale experiments and studies of borosilicate and phosphate Pu-doped glasses and zircon/zirconia, mono-zirconia, and pyrochlore ceramics. The results were used to compare and evaluate the use of these various materials in Pu immobilization.
Secrecy Capacity of a Class of Orthogonal Relay Eavesdropper Channels (2009)

The secrecy capacity of relay channels with orthogonal components is studied in the presence of an additional passive eavesdropper node. The relay and destination receive signals from the source on two orthogonal channels such that the destination also receives transmissions from the relay on its channel. The eavesdropper can overhear either one or both of the orthogonal channels. Inner and outer bounds on the secrecy capacity are developed for both the discrete memoryless and the Gaussian channel models. For the discrete memoryless case, the secrecy capacity is shown to be achieved by a partial decode-and-forward (PDF) scheme when the eavesdropper can overhear only one of the two orthogonal channels. Two new outer bounds are presented for the Gaussian model using recent capacity results for a Gaussian multiantenna point-to-point channel with a multiantenna eavesdropper. The outer bounds are shown to be tight for two subclasses of channels. The first subclass is one in which the source and relay are clustered, and the eavesdropper receives signals only on the channel from the source and the relay to the destination, for which the PDF strategy is optimal. The second is a subclass in which the source does not transmit to the relay, for which a noise-forwarding strategy is optimal.
Thermal degradation and evolved gas analysis: A polymeric blend of urea formaldehyde (UF) and epoxy (DGEBA) resin (2013)

A polymeric blend has been prepared using urea formaldehyde (UF) and epoxy (DGEBA) resin in 1:1 mass ratio. The thermal degradation of UF/epoxy resin blend (UFE) was investigated by using thermogravimetric analyses (TGA), coupled with FTIR and MS. The results of TGA revealed that the pyrolysis process can be divided into three stages: drying process, fast thermal decomposition and cracking of the sample. There were no solid products except ash content for UFE during combustion at high temperature. The total mass loss during pyrolysis at 775 °C is found to be 97.32%, while 54.14% of the original mass was lost in the second stage between 225 °C and 400 °C. It is observed that the activation energy of the second stage degradation during combustion (6.23 × 10−4 J mol−1) is more than that of pyrolysis (5.89 × 10−4 J mol−1). The emissions of CO2, CO, H2O, HCN, HNCO, and NH3 are identified during thermal degradation of UFE.
Real-time Scene Segmentation Using a Light Deep Neural Network\n Architecture for Autonomous Robot Navigation on Construction Sites (2019)

Camera-equipped unmanned vehicles (UVs) have received a lot of attention in\ndata collection for construction monitoring applications. To develop an\nautonomous platform, the UV should be able to process multiple modules (e.g.,\ncontext-awareness, control, localization, and mapping) on an embedded platform.\nPixel-wise semantic segmentation provides a UV with the ability to be\ncontextually aware of its surrounding environment. However, in the case of\nmobile robotic systems with limited computing resources, the large size of the\nsegmentation model and high memory usage requires high computing resources,\nwhich a major challenge for mobile UVs (e.g., a small-scale vehicle with\nlimited payload and space). To overcome this challenge, this paper presents a\nlight and efficient deep neural network architecture to run on an embedded\nplatform in real-time. The proposed model segments navigable space on an image\nsequence (i.e., a video stream), which is essential for an autonomous vehicle\nthat is based on machine vision. The results demonstrate the performance\nefficiency of the proposed architecture compared to the existing models and\nsuggest possible improvements that could make the model even more efficient,\nwhich is necessary for the future development of the autonomous robotics\nsystems.\n

Synthesis of the Docosanasaccharide Arabinan Domain of Mycobacterial Arabinogalactan and a Proposed Octadecasaccharide Biosynthetic Precursor (2007)

Two major components of the cell wall in mycobacteria, including Mycobacterium tuberculosis, the causative agent of tuberculosis (TB), are polysaccharides containing arabinofuranose residues. In one of these polysaccharides, arabinogalactan, this arabinan domain consists of three identical motifs of 22 arabinofuranose residues, which are in turn attached to an underlying galactofuranan backbone. Recent studies have proposed that this docosanasaccharide motif, and a structurally related arabinan present in another cell wall polysaccharide, lipoarabinomannan, are biosynthesized from a common octadecasaccharide precursor. To facilitate the testing of this hypothesis, we report here the first total syntheses of these 18- and 22-residue oligosaccharides both functionalized with an aminooctyl linker arm. The route to the target compounds involved the preparation of four tri- to heptasaccharide building blocks possessing only benzoyl protecting groups that were coupled in a highly convergent manner via glycosyl trichloroacetimidate donors. Each of the targets could be prepared in only six steps from these intermediates, and in both cases more than 10 mg of material was obtained. These compounds are expected to be useful tools in probing the biosynthesis of these arabinan-containing polysaccharides. Such studies are essential prerequisites for the identification of novel anti-TB agents that target arabinan assembly.
Antenna design of periodic and aperiodic structures (2002)

Frequency selective surfaces (FSSs) have been studied extensively in microwave and optical applications. They can be arranged in either a single layer or multiple layers to eliminate resonant crosstalk and dispersive behavior. Although literature abounds in numerical analysis and electromagnetic applications of FSSs, little has been done on the design optimization approaches for them. We examine a multilayered FSS design using gradient-based optimization methods such as sequential quadratic programming (SQP) to tune both the unit cell dimensions and dielectric layer parameters to achieve the desired frequency response.
ConfLLVM (2019)

We present a compiler-based scheme to protect the confidentiality of sensitive data in low-level applications (e.g. those written in C) in the presence of an active adversary. In our scheme, the programmer marks sensitive data by lightweight annotations on the top-level definitions in the source code. The compiler then uses a combination of static dataflow analysis, runtime instrumentation, and a novel taint-aware form of control-flow integrity to prevent data leaks even in the presence of low-level attacks. To reduce runtime overheads, the compiler uses a novel memory layout.
Reliable Respiratory Rate Estimation from a Bed Pressure Array (2006)

Unobtrusive sleep monitoring allows older adults to have continuous monitoring during the night in their own homes. We propose a method to reliably estimate respiratory rate using a bed-based pressure sensor array. Movements are detected prior to respiratory rate estimation and suppressed. The amount of movement during an estimate and a weighting for the estimate are used to create a reliability metric. The reliability metric is scored out of 100 for each sensor where high scores denote more reliable data. Once respiratory rates were calculated, the mean reliability metric determined the estimate reliability. Nocturnal data from a male and female participant was analyzed. Results show better accuracy and validity than both analysis without movement suppression and analysis with movement suppression but without postprocessing data fusion. While more than 50% of estimates include movement corruption, only 15% are unreliable and, moreover, removal of unreliable estimates significantly reduces estimate variance and provides validity estimation.
Mass spectrometry data from a quantitative analysis of protein expression in gills of immuno-challenged blue mussels (Mytilus edulis) (2016)

Here, we provide the dataset associated with our research article on the potential effects of ocean acidification on antimicrobial peptide (AMP) activity in the gills of Mytilus edulis, "Impact of ocean acidification on antimicrobial activity in gills of the blue mussel (Mytilus edulis)" [1]. Blue mussels were stimulated with lipopolysaccharides and samples were collected at different time points post injection. Protein extracts were prepared from the gills, digested using trypsin and a full in-depth proteome investigation was performed using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). Protein identification and quantification was performed using the MaxQuant 1.5.1.2 software, "MaxQuant enables high peptide identification rates, individualized p.p.b.-range mass accuracies and proteome-wide protein quantification" [2].

Abstract
Characterization of two cDNAs and identification of two proteins that accumulate in response to cadmium in cadmium-tolerant<i>Datura innoxia</i>(Mill.) cells (1996)

Changes in gene expression have been investigated in two lines of cultured Datura innoxia cells, Cd-300 and WDI, which differ in tolerance to the toxic trace metal Cd2+, Following modification of standard methodology, sufficient quantities of D. innoxia cell extracts were resolved by 2-D PAGE to allow accumulated proteins to be detected. Two Cd-induced proteins, Cd-1 and Cd-2, of approximate M 20 000, and pl 4.35 and 4.40, respectively, were detected in extracts from tolerant Cd-300 cells exposed to Cd2+, but were not observed in extracts from non-tolerant WDI cells exposed to equivalent Cd2+ treatments. However, both Cd-1 and Cd-2 were refractory to the determination of an amino acid sequence. A cDNA library was prepared from pooled polyA+ RNA isolated from Cd-300 cells exposed to a variety of Cd2+ treatments, and screened for clones containing sequences which correspond to Cd2+-induced transcripts. Two cDNAs, designated scaA and scaB, were isolated. Northern analyses confirm that both scaA and scaB transcripts increase in abundance in response to several Cd2+ treatments in Cd-300, but not WDI, cells. Both are also induced in Cd-300 cells in response to heat-shock. ScaA and ScaB are not similar to each other and show no significant similarity to any known proteins although several expressed sequence tags (ESTs) with similarity to scaA have been recorded in the gene banks.
Visualizing Assembly Dynamics of All‐Liquid 3D Architectures (Small 6/2022) (2022)

All-Liquid 3D Architectures In article number 2105017, Qun Chen, Jian-Mei Lu, Thomas P. Russell, and co-workers present interconversion of porphyrins for monitoring the time-dependent interfacial behavior of nanoparticle surfactants. In all-liquid 3D printed structures, the conversion in the aggregate state with time is reflected in a spatially varying change in the color, providing a means of assessing the aggregation state of the molecules and the mechanical properties of the assemblies, linking a macroscopic observable to mechanical properties.
Determination of 4-Hydroxy-2,5-dimethyl-3(2<i>H</i>)-furanone and 2(or 5)-Ethyl-4-hydroxy-5(or 2)-methyl-3(2<i>H</i>)-furanone in Pentose Sugar-Based Maillard Model Systems by Isotope Dilution Assays (1997)

The formation of 4-hydroxy-2,5-dimethyl-3(2H)-furanone (HDMF) and 2(or 5)-ethyl-4-hydroxy-5(or 2)-methyl-3(2H)-furanone (EHMF) from pentose sugars was studied in Maillard model systems. The amounts generated at 90 °C for 1 h were determined by isotope dilution assay (IDA). The internal standards used for IDA, i.e., [13C2]HDMF and [2H3]EHMF, were prepared in good overall yields in three steps: addition of labeled acetaldehyde or propionaldehyde to tert-butyloxycarbonyl (Boc)-protected and lithiated 3-butyn-2-ol; oxidation of the Boc-protected diol with permanganate to 1,2-dione; and finally cyclization to the target molecules after removal of the protective groups under acidic conditions. Quantitative data confirmed previous findings that HDMF and EHMF are preferentially formed in the presence of glycine and l-alanine, respectively. The yields obtained were 2.6−5.1 μg of HDMF and 6.8−10 μg of EHMF per mmol pentose. Formation of both furanones was favored in phosphate-buffered solutions at pH 7 compared to pH 5, particularly in the presence of an excess of amino acid. These data are well in agreement with the previously proposed formation mechanism of HDMF and EHMF via Strecker-assisted chain elongation of the pentose moiety. However, both furanones were also produced to a lesser extent by sugar fragmentation−condensation reactions.

Multicast Routing in Light-Trail WDM Networks (2008)

Recently, light-trail is becoming an appealing architecture for WDM networks which have been considered as promising backbone of the next generation network. Light-trail can inherently support multicast given its bus nature. In this paper, we study how to use the minimum number of light- trails to form a multicast tree for supporting the given multicast session. The problem for general light-trail WDM networks is proved to be NP-hard. Two auxiliary graphs will be proposed to transform the problem into minimum steiner tree problem that many effective algorithms can be applied. We then show that the same problem in light-trail WDM ring networks can be solved in polynomial time. The simulations show the effectiveness of our work.
Ripple Suppression of On-Chip Switched-Inductor Power Supplies (2018)

Emerging applications demand compact, battery-powered, and highly functional microsystems that require on-chip integration, low average power, and high peak-to-average power ratios. Switched inductors are popular power supplies because they are power efficient. Switching a power inductor, however, generates a nonlinear current ripple that is often difficult to tolerate and manage. The problem is more severe with on-chip nH inductors and pF capacitors. This paper explores how switching power supplies can manage and reduce this ripple. Although multiphase and filter suppressors help, analog cancellation can be 38× to 77× more effective, but also less power efficient and 23× to 55× more sensitive to mismatch from drift.
On sorption and thermal properties of the zirconium phosphate fluoride [(H2en)0.5][Zr2(PO4)2(HPO4)F]H2O (1998)

The thermal behavior of the title compound (ZrPO-1) has been investigated using conventional thermal analysis techniques as well as coupled TG–MS, TPD and XRD. Owing to the channel structure, ZrPO-1 reveals zeolitic properties in the dehydration range (up to 200 °C) whereas the removal of the organic template above 400 °C results in a complete loss of the sorptive activity. Water may be substituted by ammonia which is then released in two well separated steps atca. 150 and 300 °C, respectively. The stronger differentiation of the water sites by the ammonia sorption allows attribution of the desorption ranges to the channels and the cavities, respectively, that exist in the structure. X-Ray characterization of the product after removal of the template above 400 °C did not yield any known zirconium phosphate or oxide. EXAFS measurements show that no significant changes occur in the short-range order around zirconium neither by dehydration nor by annealing. However, the environment of zirconium becomes increasingly disordered at higher temperatures.
Semi-automatic Text and Graphics Extraction of Manga Using Eye Tracking Information (2016)

The popularity of storing, distributing and reading comic books electronically has made the task of comics analysis an interesting research problem. Different work have been carried out aiming at understanding their layout structure and the graphic content. However the results are still far from universally applicable, largely due to the huge variety in expression styles and page arrangement, especially in manga (Japanese comics). In this paper, we propose a comic image analysis approach using eye-tracking data recorded during manga reading sessions. As humans are extremely capable of interpreting the structured drawing content, and show different reading behaviors based on the nature of the content, their eye movements follow distinguishable patterns over text or graphic regions. Therefore, eye gaze data can add rich information to the understanding of the manga content. Experimental results show that the fixations and saccades indeed form consistent patterns among readers, and can be used for manga textual and graphical analysis.
P2‐081: Brain localization of cognitive domains with diffusion MRI (2008)

Aging is a complex heterogeneous process accompanied by cognitive decline. Diffusion-tensor imaging (DTI) measures the displacement of water molecules in vivo non-invasively. This technique has demonstrated that aging is associated with an increase in the apparent diffusion coefficient (ADC), most prominently in the frontal lobe. MRI was performed on a 3T (GE) MRI system in 51 healthy volunteers (25–82 y). DTI analysis and construction of ADC maps was performed followed by normalization to the standard Montreal Neurological Institute template and spatial smoothing. Subjects completed a battery of computerized tests (Mindstreams®, NeuroTrax Corp., NJ) assessing cognitive performance in multiple domains. Factor analysis of 55 cognitive scores resulted in three cognitive domains: memory, verbal function and processing speed. DTI using voxel-based analysis (VBA) was used to quantify regional brain changes due to age-related cognitive decline in these domains controlling for age. Negative partial correlation between memory accuracy and ADC was found mainly in temporal and frontal gray and white matter, including the parahippocampus, orbitofrontal, inferior frontal gyrus, middle frontal gyrus, anterior cingulate, broca's area, and insula (Figure 1, red). Negative partial correlation between verbal accuracy and ADC was found mainly in white matter, in frontal white matter, in the superior longitudinal fasciculus (SLF) and in the cingulum (Figure 1, blue). Positive partial correlation between processing speed and ADC was mainly in the white matter, in the posterior parts of the SLF, cingulum, posterior corona radiata and postcentral gyrus (Figure 1, green). Partial correlation of the cognitive domains with ADC revealed a region-specific pattern, with regions exhibiting substantial correlation playing an important role in the corresponding functional domain. ADC in the hippocampus, orbitofrontal cortex, and Broca's area, memory related areas, was correlated with memory performance. ADC in the SLF, which connects the language areas (Wernicke's and Broca's), was significantly correlated with verbal performance. ADC in the posterior corona radiata, related to motor speed, and parietal white matter, involved in calculation tasks, were correlated with the processing speed. Correlating cognitive performance and quantitative measures of brain morphology can be used for indirect functional localization of cognitive domains.
Upper Bounds for the Security of two Distributed-Phase Reference Protocols of Quantum Cryptography (Coherent-One-Way and Differential-Phase-Shift) (2007)

The Differential-Phase-Shift (DPS) and the Coherent-One-Way (COW) are among the most practical protocols for quantum cryptography, and are therefore the object of fast-paced experimental developments. The assessment of their security is also a challenge for theorists: the existing tools, that allow to prove security against the most general attacks, do not apply to these two protocols in any straightforward way. We present new upper bounds for their security in the limit of large distances ($d \gtrsim 50$km with typical values in optical fibers) by considering a large class of collective attacks, namely those in which the adversary attaches ancillary quantum systems to each pulse or to each pair of pulses. We introduce also two modified versions of the COW protocol, which may prove more robust than the original one.
&lt;title&gt;Implementation of phase-only coded ternary filters for filtering-based optical processors&lt;/title&gt; (2001)

This paper addresses a method to implement ternary filters with binary phase spatial light modulators (SLMs) for real-time optical pattern recognition applications using a filtering-based optical processor. A complex ternary filter can be considered as a binary phase function multiplied by a binary amplitude filter, which selects information by blocking or letting pass spatial frequencies. The main problem is that commercially available SLMs cannot provide amplitude and phase modulation at the same time and at high filtering rates. The method presented here involves coding the binary amplitude in phase only, by adding a linear phase to the frequencies representing undesired information. This information will be rejected outside the correlation plane, whereas useful information will pass without alteration. Computer simulations and experimental results have been obtained for different applications. These results show that the pure phase filters obtained are absolutely equivalent to the desired ternary filters and, furthermore, that any ternary filtering function can be easily implemented in a VanderLugt correlator that uses a binary phase SLM, thanks to this technique.
