Impact of the Siloxane-Terminated Side Chain on Photovoltaic Performances of the Dithienylbenzodithiophene–Difluorobenzotriazole-Based Wide Band Gap Polymer Donor in Non-Fullerene Polymer Solar Cells (2019)

To thoroughly disclose the role of the siloxane-terminated side chain with different substituent positions, three difluorobenzotriazole-dithienylbenzodithiophene (FTAZ-BDTT)-based polymers PBZ-1Si, PBZ-2Si, and PBZ-3Si with the siloxane-terminated side chain on the FTAZ unit (PBZ-1Si), on the BDTT unit (PBZ-2Si), and both on BDTT and FTAZ units (PBZ-3Si), respectively, were synthesized. The different side chain substitutions have slight influences on absorption behavior, thermal stability, and frontier molecular orbitals but have shown a great effect on the aggregation of the polymers. Grazing-incidence wide-angle X-ray scattering measurements reveal that, relative to PBZ-1Si with branched alkyl on the BDTT unit, polymers PBZ-2Si and PBZ-3Si, bearing the siloxane-terminated side chains on the BDTT unit, exhibit smaller π-π stacking distances and larger crystal coherence lengths, suggesting that adopting the siloxane-terminated side chain on the BDTT unit can promote the interchain π-π interaction and the ordering of molecular packing. With IT-M as the non-fullerene acceptor, among the three polymers, the PBZ-2Si-based active layer possesses the highest ordered crystals for both polymers and IT-M as well as the purest domain, which affords efficient exciton dissociation, the most balanced hole-electron transport, and reduced recombination, leading to the highest short-circuit current density (<i>J</i><sub>sc</sub>) and fill factor (FF) and then the highest power conversion efficiency (PCE) of 11.14%. In contrast, PBZ-1Si- and PBZ-3Si-based devices show lower PCEs of 8.98 and 9.92%, respectively. Moreover, PBZ-2Si:IT-M also exhibits good thickness tolerance, and its thick active layer of 240 nm shows the most limited decrease of efficiency after 77 days of storage, supplying good potential for mass fabrication. Our work suggests that the fine pairing of a siloxane-terminated side chain and an alkyl side chain is beneficial for the optimizing of a conjugated polymer donor toward high-performance non-fullerene polymer solar cells.
Contact Self-Cleaning of Synthetic Gecko Adhesive from Polymer Microfibers (2008)

Natural gecko toes covered by nanomicro structures can repeatedly adhere to surfaces without collecting dirt. Inspired by geckos, we fabricated a high-aspect-ratio fibrillar adhesive from a stiff polymer and demonstrated self-cleaning of the adhesive during contact with a surface. In contrast to a conventional pressure-sensitive adhesive (PSA), the contaminated synthetic fibrillar adhesive recovered about 33% of the shear adhesion of clean samples after multiple contacts with a clean, dry surface.
Adversarial Structure Matching Loss for Image Segmentation. (2018)

The per-pixel cross-entropy loss (CEL) has been widely used in structured output prediction tasks as a spatial extension of generic image classification. However, its i.i.d. assumption neglects the structural regularity present in natural images. Various attempts have been made to incorporate structural reasoning mostly through structure priors in a cooperative way where co-occuring patterns are encouraged. We, on the other hand, approach this problem from an opposing angle and propose a new framework for training such structured prediction networks via an adversarial process, in which we train a structure analyzer that provides the supervisory signals, the adversarial structure matching loss (ASML). The structure analyzer is trained to maximize ASML, or to exaggerate recurring structural mistakes usually among co-occurring patterns. On the contrary, the structured output prediction network is trained to reduce those mistakes and is thus enabled to distinguish fine-grained structures. As a result, training structured output prediction networks using ASML reduces contextual confusion among objects and improves boundary localization. We demonstrate that ASML outperforms its counterpart CEL especially in context and boundary aspects on figure-ground segmentation and semantic segmentation tasks with various base architectures, such as FCN, U-Net, DeepLab, and PSPNet.
Chromosome Organization by a Nucleoid-Associated Protein in Live Bacteria (2011)

Bacterial chromosomes are confined in submicrometer-sized nucleoids. Chromosome organization is facilitated by nucleoid-associated proteins (NAPs), but the mechanisms of action remain elusive. In this work, we used super-resolution fluorescence microscopy, in combination with a chromosome-conformation capture assay, to study the distributions of major NAPs in live Escherichia coli cells. Four NAPs--HU, Fis, IHF, and StpA--were largely scattered throughout the nucleoid. In contrast, H-NS, a global transcriptional silencer, formed two compact clusters per chromosome, driven by oligomerization of DNA-bound H-NS through interactions mediated by the amino-terminal domain of the protein. H-NS sequestered the regulated operons into these clusters and juxtaposed numerous DNA segments broadly distributed throughout the chromosome. Deleting H-NS led to substantial chromosome reorganization. These observations demonstrate that H-NS plays a key role in global chromosome organization in bacteria.
A Novel Distributed Telerobotic System for Construction Machines Based on Modules Synchronization (2006)

On a scene of a natural disaster, rescuers require heavy duty hydraulic machines to answer their need of large forces, or to approach an unreachable spot. Those industrial vehicles are hydraulically actuated arms kinematically different, and equipped by specific tools to fit the task to accomplish. They require trained operators because of their complex use. As time and accuracy are primordial factors to save lives in such a situation, the use of automation and robotic concepts on the control of those machines becomes necessary. The standard approach is to use manual teleoperation based on a bilateral master/slave system, to enhance the maneuverability of the machines, but their diversity is nearly never taken into account. We propose here, a modular platform based on an original synchronization of module states that allows easy manipulator changes and flexibility of use. We will describe the proposed concept of intelligent interface, and verify its utility and performances through some pertinent configurations and experiment
Modeling for Traffic Replay in Virtual Network (2018)

Replaying traffic in a virtual network based on IP-Mapping not only helps the traffic play its full data value but also helps the virtual network enhance the authenticity by introducing the background traffic and fully restoring the actual details of the behavior to be studied. Replaying traffic in the virtual network should first establish the mapping relationships between the IP addresses in traffic and virtual nodes of virtual networks. In this paper, we propose a generalized modeling approach for replaying traffic in a virtual network constructed by network emulation platforms. Any traffic captured or generated by only one or multi-interfaces could be replayed by virtual nodes based on IP mapping. IP addresses in traffic will be divided into disjoint sets based on the graph coloring algorithm in which IP addresses in the same set will not communicate with each other, and IP addresses in different sets will communicate with each other through a certain network interface. Modeling of the virtual network will calculate the communicating relationships between virtual nodes through a certain virtual network interface based on a hierarchical algorithm. It is proved to be a fundamental and general modeling approach for mapping the endpoint in traffic to the virtual nodes. We replay LLS_DDOS 1.0 in a certain virtual network as a case to demonstrate the modeling process of our approach.
Modeling treatment of ischemic heart disease with partially observable Markov decision processes. (1998)

Diagnosis of a disease and its treatment are not separate, one-shot activities. Instead they are very often dependent and interleaved over time, mostly due to uncertainty about the underlying disease, uncertainty associated with the response of a patient to the treatment and varying cost of different diagnostic (investigative) and treatment procedures. The framework of Partially observable Markov decision processes (POMDPs) developed and used in operations research, control theory and artificial intelligence communities is particularly suitable for modeling such a complex decision process. In the paper, we show how the POMDP framework could be used to model and solve the problem of the management of patients with ischemic heart disease, and point out modeling advantages of the framework over standard decision formalisms.
Cerebral Autoregulation Real-Time Monitoring (2016)

Cerebral autoregulation is a mechanism which maintains constant cerebral blood flow (CBF) despite changes in mean arterial pressure (MAP). Assessing whether this mechanism is intact or impaired and determining its boundaries is important in many clinical settings, where primary or secondary injuries to the brain may occur. Herein we describe the development of a new ultrasound tagged near infra red light monitor which tracks CBF trends, in parallel, it continuously measures blood pressure and correlates them to produce a real time autoregulation index. Its performance is validated in both in-vitro experiment and a pre-clinical case study. Results suggest that using such a tool, autoregulation boundaries as well as its impairment or functioning can be identified and assessed. It may therefore assist in individualized MAP management to ensure adequate organ perfusion and reduce the risk of postoperative complications, and might play an important role in patient care.
Self-organization of dislocation-free, high-density, vertically aligned GaN nanocolumns involving InGaN quantum wells on graphene/SiO<sub>2</sub>covered with a thin AlN buffer layer (2015)

We demonstrated the self-organization of high-density GaN nanocolumns on multilayer graphene (MLG)/SiO2 covered with a thin AlN buffer layer by RF-plasma-assisted molecular beam epitaxy. MLG/SiO2 substrates were prepared by the transfer of CVD graphene onto thermally oxidized SiO2/Si [100] substrates. Employing the MLG with an AlN buffer layer enabled the self-organization of high-density and vertically aligned nanocolumns. Transmission electron microscopy observation revealed that no threading dislocations, stacking faults, or twinning defects were included in the self-organized nanocolumns. The photoluminescence (PL) peak intensities of the self-organized GaN nanocolumns were 2.0-2.6 times higher than those of a GaN substrate grown by hydride vapor phase epitaxy. Moreover, no yellow luminescence or ZB-phase GaN emission was observed from the nanocolumns. An InGaN/GaN MQW and p-type GaN were integrated into GaN nanocolumns grown on MLG, displaying a single-peak PL emission at a wavelength of 533 nm. Thus, high-density nitride p-i-n nanocolumns were fabricated on SiO2/Si using the transferred MLG interlayer, indicating the possibility of developing visible nanocolumn LEDs on graphene/SiO2.

Monoclonal antibodies to HLA-DP-transfected mouse L cells. (1986)

Mouse L cells transfected with human HLA-DP (DPw4) alpha and beta genes were used to make monoclonal antibodies in C3H mice. A polymorphic antibody, DP11.1, was obtained, as well as several monomorphic antibodies. In ELISAs, DP11.1 bound to DPw4 cells and, more weakly, to DPw2, but not DPw1, -3, -5, or -6, using HLA homozygous cells. It also bound to L-cell transfectants expressing either DPw2 or DPw4 products. From B lymphoblastoid cell lysates labeled with [35S]methionine, the antibody immunoprecipitated alpha and beta chains of a similar size to those precipitated by a well-characterized DP monoclonal antibody, B7/21.2. Immunoblotting indicated that the DP11.1 antibody was directed against the alpha chain. This result confirms partial sequence data that showed that the DP alpha chain, as well as DP beta, is polymorphic, and that DPw2 and -4 alpha chains are very similar, if not identical.
Variational Exemplar-Based Image Colorization (2013)

In this paper, we address the problem of recovering a color image from a grayscale one. The input color data comes from a source image considered as a reference image. Reconstructing the missing color of a grayscale pixel is here viewed as the problem of automatically selecting the best color among a set of color candidates while simultaneously ensuring the local spatial coherency of the reconstructed color information. To solve this problem, we propose a variational approach where a specific energy is designed to model the color selection and the spatial constraint problems simultaneously. The contributions of this paper are twofold. First, we introduce a variational formulation modeling the color selection problem under spatial constraints and propose a minimization scheme, which computes a local minima of the defined nonconvex energy. Second, we combine different patch-based features and distances in order to construct a consistent set of possible color candidates. This set is used as input data and our energy minimization automatically selectsthe best color to transfer for each pixel of the grayscale image. Finally, the experiments illustrate the potentiality of our simple methodology and show that our results are very competitive with respect to the state-of-the-art methods.
SECURE BRIDGING IN LARGE SCALE DEPLOYMENT OF ETHERNET (2010)

Considering the dominance of Ethernet with upcoming 100 Gbps line rate, service providers want to reduce their transport networks to simpler Layer-2 networks. Since existing Ethernet security mechanisms protect links in hop-by-hop basis, they cannot control access for disloyal authorized users in virtual or logical shared media infrastructure LANs. Also they leave data in clear inside intermediate systems, which increase threats when these systems are placed in public places. To address these critical security issues, we propose an authenticated on-demand secure bridging solution that can provide a point-to-point secure channel between Ingress and Egress Bridges across Bridged Ethernet network. To build such secure channel, we use Identity-based authenticated key agreement and signature protocol. Experimental results using our prototype software on a small multi-segment Ethernet network suggest that our solution is feasible, and guarantees secure bridging.
SAR imaging using WiMAX OFDM PHY (2011)

Modern communication systems provide myriad opportunities for passive radar applications. Understanding the structure and potential of these signals becomes critical in the design and concept development process of passive radar systems. Although research exists for passive coherent target location, there is much to be explored in the passive radar imaging realm using signals of opportunity. This paper presents an evaluation of the IEEE 802.16-2009 WiMAX OFDM physical layer as a potential signal for a passive imaging radar system. The use of OFDM signals in radar imaging is explored and basic WiMAX imaging properties are discussed.
Phosphate starvation induces uptake of glyphosate by Pseudomonas sp. strain PG2982 (1988)

Pseudomonas sp. strain PG2982 has the ability to use the phosphonate herbicide, glyphosate, as a sole phosphorus source (J. K. Moore, H. D. Braymer, and A. D. Larson, Appl. Environ. Microbiol. 46:316-320, 1983). Glyphosate uptake is maximal in the late log phase of growth and is induced by phosphate starvation. Uptake is inhibited by phosphate and arsenate, but not by the amino acids glycine and sarcosine. The Km and Vmax for glyphosate uptake were calculated to be 23 microM and 0.97 nmol/mg (dry weight) per min, respectively. A phosphate transport system with a broad substrate specificity may be responsible for glyphosate uptake.
A 75.9dB-SNDR 2.96mW 29fJ/conv-step ringamp-only pipelined ADC (2013)

A high resolution pipelined ADC that performs precision amplification using only ring amplifiers is presented. Several enabling techniques are introduced, namely parallelization via the use of Composite Ring Amplifier Blocks and a new ringamp topology designed for high-precision use. The 15b ADC achieves 75.9 dB SNDR and 91.4 dB SFDR at 1.2 V supply and 20 Msps conversion rate. Total power consumption is 2.96 mW, resulting in a Figure-of-Merit of 29 fJ/c-step.
The  Escherichia coli  highly expressed entD gene complements the pfaE  deficiency in a pfa gene clone responsible for the biosynthesis of long-chain n-3 polyunsaturated fatty acids (2010)

The Escherichia coli entD gene, which encodes an Sfp-type phosphopantetheinyl transferase (PPTase) that is involved in the biosynthesis of siderophore, is available as a high-expression ASKA clone (pCA24N::entD) constructed from the E. coli K-12 strain AG1. In E. coli DH5alpha, pCA24N::entD complemented a pfaE-deficient clone that comprised pfaA, pfaB, pfaC and pfaD, which are four of the five pfa genes that are responsible for the biosynthesis of eicosapentaenoic acid derived from Shewanella pneumatophori SCRC-2738. Sfp-type PPTases are classified into the EntD and PfaE groups, based on differences between their N-terminal-domain structures. Here, we showed that all Sfp-type PPTases may have the potential to promote the biosynthesis of long-chain n-3 polyunsaturated fatty acids.

Density Measurement of Cylindrical Specimens Within a Mold by Gamma-Rays (1993)

Abstract This paper describes a series of tests used to establish a method of nondestructive density measurements of cylindrical specimens contained within a mold by using a twin-probe gamma-ray density gage. Cylindrical specimens within molds are common occurrence in civil engineering practice; examples are soil, concrete, or bituminous cores obtained by in situ sampling or laboratory compaction. In several applications it may be desirable to determine the core densities without removal from the mold, and this can be achieved by the use of a gamma-ray density gage which is an adaptation of a twin-probe direct transmission field gage for laboratory density measurement. It is shown that linear calibration relationships can be obtained by two different procedures. The first case is to use the count ratio between the count rate of specimen with mold to count rate of air plotted against the composite density of the specimen and mold. The composite density is computed using the irradiated volumetric proportions of the specimen and mold. The other case is to use the count ratio between the count rate of specimen and mold to the count rate of mold only plotted against the density of the specimen. Experiments were conducted with three aluminum molds of 116, 119, and 124 mm external diameters and 102 mm internal diameter, for five specimens of 100 mm diameters with density froms 0.87 to 2.70 g/cm3. Based on the radiation attenuation law, a theoretical basis for the linear calibration in the two cases are established. Comparison of the theoretical slopes of the calibration lines with the experimental slopes showed excellent agreement, thus verifying the validity of the calibration procedures.
