High Performance SrFe 0.2 Co 0.4 Mo 0.4 O 3− δ Ceramic Anode Supported Low-Temperature SOFCs (2021)

The development of alternative ceramic anodes for low-temperature solid oxide fuel cells (LT-SOFCs) is essential to overcome the inherent challenges such as redox instability and coking associated with Ni-based cermet anodes. Moreover, due to the large electrolyte ohmic loss at low temperature, it is critical to developing an electrode supported cell that allows electrolyte thickness reduction. Here we successfully demonstrated a high performance SrFe 0.2 Co 0.4 Mo 0.4 O 3− δ (SFCM) ceramic anode supported LT-SOFC with a peak power density of 730 mW cm −2 and 300 mW cm −2 at ambitious low temperatures of 550 °C and 450 °C, respectively, in humidified H 2 . The new anode material SFCM exhibits exceptional conductivity of over 30 S cm −1 at 450 °C in humidified H 2 , providing essential current collection capability as an anode backbone appropriate for the infiltration of Ni-gadolinia doped ceria (GDC) electrocatalysts. Compared to conventional Ni-cermet anodes, the nano-sized Ni-GDC particles in our SFCM based electrode significantly improves the cell stability in hydrocarbon gases. We demonstrated a stable long-term operation over a period of 380 h in CH 4 –containing gas mixtures at 450 °C with a voltage degradation rate of 4% per 1000 h at a constant current of 0.2 A*cm −2 . Our results demonstrate a high performance ceramic anode with high stability for low temperature operation.
Low Data Drug Discovery with One-Shot Learning (2017)

2015, 55, 263-274). However, the applicability of these techniques has been limited by the requirement for large amounts of training data. In this work, we demonstrate how one-shot learning can be used to significantly lower the amounts of data required to make meaningful predictions in drug discovery applications. We introduce a new architecture, the iterative refinement long short-term memory, that, when combined with graph convolutional neural networks, significantly improves learning of meaningful distance metrics over small-molecules. We open source all models introduced in this work as part of DeepChem, an open-source framework for deep-learning in drug discovery (Ramsundar, B. deepchem.io. https://github.com/deepchem/deepchem, 2016).
Transparent mobile service terminal: an overview (2012)

It is a consensus that ubiquitous/pervasive computing paradigm will be a mainstream in the future of computing devices. Based on the extended von Neumann architecture, transparent computing is one of the most promising means of realising ubiquitous/pervasive computing. Transparent mobile service terminal (TMST), being a handheld mobile device powered by transparent computing system, is a natural fit for the client terminal of the transparent computing system. TMST uses transparent network OS (TNOS) as the core of its system, thus enjoys numerous benefits such as service-oriented, light-loaded, rich functionality, high security, improved manageability, high efficiency and enhanced user experience. In this paper, a conceptual description of the innovative technologies behind the TMST is presented.

Modeling and Analysis of a Broadband Schottky Diode Noise Source Up To 325 GHz Based on 55-nm SiGe BiCMOS Technology (2020)

In this article, the electrical model of a millimeter-wave (mmW), silicon-based noise source is developed in the frequency range up to 325 GHz. The model is studied as a function of the biasing current and the structure size. The noise source is based on a Schottky diode realized on the 55-nm SiGe BiCMOS technology from STMicroelectronics, Crolles, France. Due to the ability of being integrated on silicon, this noise source can be used for high-frequency in situ noise characterization of advanced silicon CMOS or bipolar technologies in the mmW range. In previous study, the diode was used as a noise source when biased near the avalanche regime, and an excess noise ratio (ENR) up to 20 dB has been achieved in a frequency range up to 260 GHz. In this article, the ENR value of the diode is retrieved from the electrical model and compared to the value extracted by measurements. The extracted ENR value was also studied for several diode sizes and biasing currents and measured up to 325 GHz, with a good agreement with the modeling.
Transient thermal stress analysis of a proposed pion production target (1978)

The results of a transient temperature and stress analysis of a proposed LAMPF proton target are presented. The target configuration, suitable for the LAMPF A-1, A-2, or A-5 pion production sites (800-MeV protons, 1-mA average current), is composed of pyrolytic graphite and is cooled by flowing water. Special attention is paid to the pulsed nature of the proton beam (6% duty). The computer code TSAAS is used to develop a temperature and stress history of the target during the first five beam pulses and the final, steady-state temperature distribution. The results of this analysis indicate that a conduction-cooled pyrolytic graphite target of the type shown in this report wil be suitable as a LAMPF pion production target at a beam current of 1 mA.
Assessment of a chloride-containing vs. a chloride-poor modified HTK solution in a rat liver transplantation model (2009)

Aims: We recently developed a modified preservation solution on the basis of histidine-tryptophan-ketoglutarate (HTK) solution. Recent in vitro studies on cold-induced cell injury revealed detrimental effects of extracellular chloride during cold storage of isolated rat hepatocytes while the influence of chloride on various endothelial cells was beneficial. In order to find out which of these effects predominates in vivo, we here tested a chloride-poor vs. a chloride-containing variant (0.04 vs. 34.04 mM Cl-) of the new solution in a rat liver transplantation model.
Application of Pseudo Strain-hardening Cementitious Composites to Shear Resistant Structural Elements (1998)

This article describes design concept and material characteristics of a new ductile fiber reinforced cementitious composite referred to as ECC (Engineered Cementitious Composite). This particular ECC contains Polyvinyl Alcohol fiber and exhibits remarkably ductile tensile property with over 1% of tensile strain capacity. The high tensile strain performance of the ECC was found successfully utilized to improve the performance of structural elements via two demonstrative examples. First, it was found that ECC significantly enhanced shear performance of short span beam under cyclic loading. Second, ECC enables one to realize simple dry joint connecting panels with remarkably high shear load capacity for structural wall assembly. As conclusion, a strong potential of the ECC has been established to enhance the structural performance of seismic resistant elements.
LOAD TRANSFER IN PRESSURE INJECTED ANCHORS-CLOSURE (1980)

This paper is a closure written by the original authors in response to a discussion of their paper concerning anchor movements. The writers agree with the discusser that elastic theory is a useful tool in the investigation of tieback anchor behavior; however, they feel than an analysis that includes the interaction between anchor elongation and strains in the adjacent soil, such as the Mindlin equation approach of Mattes and Poulos or a finite element analysis, is more appropriate for this particular type of anchor because of the very high slenderness ratios, L/d, of typical-pressure-injected anchors. With reference to the computations presented by the discusser, the writers point out that a composite anchor modulus is used in the computations whereas a cracked grout section would appear to be more correct. With respect to the selection of soil moduli for the discusser's computations, it is noted that the stress-strain response of the soil in a relatively thin zone adjacent to the anchor has a major influence of the anchor response. Increased confining pressures due to the high radial stresses induced in the soil around pressure-injected anchors could significantly increase the soil modulus in this zone.
Differential effects on inhibition of cholesterol absorption by plant stanol and plant sterol esters in apoE-/- mice (2011)

PSE and PSA supplementation reduced serum cholesterol, but increased plant sterol and plant stanol concentrations. Elevated levels of PSE and PSA were associated with endothelial dysfunction and increased central nervous system depositions. Atherosclerotic lesion retardation was more pronounced in WTD + PSA, coinciding with higher regenerative monocyte numbers, decreased oxidative stress, and decreased inflammatory cytokines compared with WTD + PSE.
Reductive Dissolution and Precipitation of Manganese Associated with Biodegradation of Petroleum Hydrocarbons (2000)

Dissolved manganese affects the aesthetic quality of groundwater used for domestic purposes. Reducing conditions created by natural biodegradation of petroleum hydrocarbons in contact with groundwater can cause manganese to dissolve from aquifer sediments. However, the reaction is reversible by chemical oxidation downgradient of the bioremediation shadow. Geochemical modeling (MINTEQA2) predicts the redox conditions for manganese to precipitate from groundwater back to aquifer sediments. The reaction rate for manganese precipitation is related to the advective and dispersive transport of dissolved oxygen in groundwater. At a petroleum release site in central California, the reaction rate was observed to follow first-order kinetics. By knowing the site-specific aqueous geochemistry and reaction kinetics, measures can be taken with reasonable certainty to construct water supply wells to avoid producing water containing unacceptable levels of manganese. Biodegradation of petroleum hydrocarbons in the environment is well-documented, widespread, and naturally occurring (Wiedemeier et al., 1999). Where petroleum hydrocarbons undergo natural biodegradation in contact with groundwater, dissolved manganese may be found at relatively high concentrations in the groundwater (Deutsch, 1997). The presence of manganese can affect the aesthetic quality of groundwater for domestic use due to precipitation of the manganese as black deposits on fixtures and clothing (Driscoll, 1986). The U.S. Environmental Protection Agency (USEPA) has established a Secondary Maximum Contaminant Level (MCL) of 0.05 mg/L for manganese in drinking water (tap water). Some states, including California, have established similar limits for manganese based on aesthetic considerations (California Department of Health Services, 2000). The persistence of dissolved manganese associated with the biodegradation of petroleum hydrocarbons is an important consideration in deciding whether engineered remediation of a petroleum release in contact with groundwater is necessary. The dissolution of manganese is reversible under oxidizing conditions. In this article, geochemical methods are used to predict the precipitation of dissolved manganese outside the region affected by petroleum biodegradation. These predictions are compared with monitoring results from a petroleum release site in central California.

Depth from focus with your mobile phone (2015)

While prior depth from focus and defocus techniques operated on laboratory scenes, we introduce the first depth from focus (DfF) method capable of handling images from mobile phones and other hand-held cameras. Achieving this goal requires solving a novel uncalibrated DfF problem and aligning the frames to account for scene parallax. Our approach is demonstrated on a range of challenging cases and produces high quality results.
FOXO1 controls protein synthesis and transcript abundance of mutant polyglutamine proteins, preventing protein aggregation (2021)

FOXO1, a transcription factor downstream of the insulin/insulin like growth factor axis, has been linked to protein degradation. Elevated expression of FOXO orthologs can also prevent the aggregation of cytosine adenine guanine (CAG)-repeat disease causing polyglutamine (polyQ) proteins but whether FOXO1 targets mutant proteins for degradation is unclear. Here, we show that increased expression of FOXO1 prevents toxic polyQ aggregation in human cells while reducing FOXO1 levels has the opposite effect and accelerates it. Although FOXO1 indeed stimulates autophagy, its effect on polyQ aggregation is independent of autophagy, ubiquitin-proteasome system (UPS) mediated protein degradation and is not due to a change in mutant polyQ protein turnover. Instead, FOXO1 specifically downregulates protein synthesis rates from expanded pathogenic CAG repeat transcripts. FOXO1 orchestrates a change in the composition of proteins that occupy mutant expanded CAG transcripts, including the recruitment of IGF2BP3. This mRNA binding protein enables a FOXO1 driven decrease in pathogenic expanded CAG transcript- and protein levels, thereby reducing the initiation of amyloidogenesis. Our data thus demonstrate that FOXO1 not only preserves protein homeostasis at multiple levels, but also reduces the accumulation of aberrant RNA species that may co-contribute to the toxicity in CAG-repeat diseases.
Attacking DoH and ECH: Does Server Name Encryption Protect Users’ Privacy? (2022)

Privacy on the Internet has become a priority, and several efforts have been devoted to limit the leakage of personal information. Domain names, both in the TLS Client Hello and DNS traffic, are among the last pieces of information still visible to an observer in the network. The Encrypted Client Hello extension for TLS, DNS over HTTPS or over QUIC protocols aim to further increase network confidentiality by encrypting the domain names of the visited servers. In this article, we check whether an attacker able to passively observe the traffic of users could still recover the domain name of websites they visit even if names are encrypted. By relying on large-scale network traces, we show that simplistic features and off-the-shelf machine learning models are sufficient to achieve surprisingly high precision and recall when recovering encrypted domain names. We consider three attack scenarios, i.e., recovering the per-flow name, rebuilding the set of visited websites by a user, and checking which users visit a given target website. We next evaluate the efficacy of padding-based mitigation, finding that all three attacks are still effective, despite resources wasted with padding. We conclude that current proposals for domain encryption may produce a false sense of privacy, and more robust techniques should be envisioned to offer protection to end users.
Spectroscopic analysis of polymer-ceramic dental composites after accelerated aging. (2003)

All materials tested underwent a surface change after the aging process. Artglass and Targis changed minimally into whitish/reddish and yellowish appearances, respectively. An organic-rich surface was produced by a combination of washout of filler particles and rearrangement of polymer molecules through diffusion.
Temporal events in cyclopean vision. (1996)

The majority of neurons in the primary visual cortex of primates can be activated by stimulation of either eye; moreover, the monocular receptive fields of such neurons are located in about the same region of visual space. These well-known facts imply that binocular convergence in visual cortex can explain our cyclopean view of the world. To test the adequacy of this assumption, we examined how human subjects integrate binocular events in time. Light flashes presented synchronously to both eyes were compared to flashes presented alternately (asynchronously) to one eye and then the other. Subjects perceived very-low-frequency (2 Hz) asynchronous trains as equivalent to synchronous trains flashed at twice the frequency (the prediction based on binocular convergence). However, at higher frequencies of presentation (4-32 Hz), subjects perceived asynchronous and synchronous trains to be increasingly similar. Indeed, at the flicker-fusion frequency (approximately 50 Hz), the apparent difference between the two conditions was only 2%. We suggest that the explanation of these anomalous findings is that we parse visual input into sequential episodes.
Legionella spp. outdoors: colonization, communication and persistence (2011)

Bacteria of the genus Legionella persist in a wide range of environmental habitats, including biofilms, protozoa and nematodes. Legionellaceae are 'accidental' human pathogens that upon inhalation cause a severe pneumonia termed 'Legionnaires' disease'. The interactions of L. pneumophila with eukaryotic hosts are governed by the Icm/Dot type IV secretion system (T4SS) and more than 150 'effector proteins', which subvert signal transduction pathways and promote the formation of the replication-permissive 'Legionella-containing vacuole'. The Icm/Dot T4SS is essential to infect free-living protozoa, such as the amoeba Dictyostelium discoideum, as well as the nematode Caenorhabditis elegans, or mammalian macrophages. To adapt to different niches, L. pneumophila not only responds to exogenous cues, but also to endogenous signals, such as the α-hydroxyketone compound LAI-1 (Legionella autoinducer-1). The long-term adaptation of Legionella spp. is based on extensive horizontal DNA transfer. In fact, Legionella spp. have acquired canonical 'genomic islands' of prokaryotic origin, but also a number of eukaryotic genes. Since many aspects of Legionella virulence against environmental predators and immune phagocytes are similar, an understanding of Legionella ecology provides valuable insights into the pathogenesis of legionellaceae for humans.
Experimental Validation of Force Radiation Modes: A Novel Approach to Reduction of Sound Radiation from Vibrating Structure (2011)

OESCLIM is well tolerated locally and systemically in long-term therapy with a high proportion of patients wishing to continue therapy after 1 year.
Time Lapse Photography for High-Throughput Phenotyping of Corn (2019)

Comprehensive assessment of plant performance requires taking various measurements in the field throughout the growing season. These measurements are time consuming. To increase the sampling frequency of trait assessment, a time-lapse photography system was developed. The cameras take images at user-specified intervals (e.g., every 15 minutes) throughout the growing season, which allows us to measure various plant traits at a high frequency with minimal daily labor.
The ubiquitin-like modifier FAT10 interacts with HDAC6 and localizes to aggresomes under proteasome inhibition (2008)

During misfolded-protein stress, the cytoplasmic protein histone deacetylase 6 (HDAC6) functions as a linker between the dynein motor and polyubiquitin to mediate the transport of polyubiquitylated cargo to the aggresome. Here, we identify a new binding partner of HDAC6, the ubiquitin-like modifier FAT10 (also known as UBD), which is cytokine-inducible and - similar to ubiquitin - serves as a signal for proteasomal degradation. In vivo, the two proteins only interacted under conditions of proteasome impairment. The binding of HDAC6 to FAT10 was mediated by two separate domains: the C-terminal ubiquitin-binding zinc-finger (BUZ domain) of HDAC6 and its first catalytic domain, even though catalytic activity of HDAC6 was not required for this interaction. Both endogenous and ectopically expressed FAT10 as well as the model conjugate FAT10-GFP localized to the aggresome in a microtubule-dependent manner. Furthermore, FAT10-containing as well as ubiquitin-containing aggresomes were reduced in both size and number in HDAC6-deficient fibroblasts. We conclude that, if FAT10 fails to subject its target proteins to proteasomal degradation, an alternative route is taken to ensure their sequestration and possibly also their subsequent removal by transporting them to the aggresome via the association with HDAC6.
UWB PIFA Antenna for Simplified Transceivers (2010)

A planar inverted-F antenna (PIFA) with an input match designed to offer the capability of a front-end bandpass filter in mobile communication transceivers is presented. The proposed antenna is low cost, easily fabricated, and operates in the unlicensed lower band (3.168– 4.752 GHz) of the ultra-wideband (UWB) communication standard with a 3.57:1 VSWR. It is demonstrated that the antenna possesses a radiation pattern with good front-to-back ratio and shows acceptable impedance matching in proximity to large ground planes making it suitable for applications such as in-vehicle communications.
On-line generalized Steiner problem (1996)

The generalized Steiner problem (GSP) is defined as follows. We are given a graph with non-negative edge weights and a set of pairs of vertices. The algorithm has to construct minimum weight subgraph such that the two nodes of each pair are connected by a path.Off-line GSP approximation algorithms were given in Agarwal et al. (SIAM J. Comput. 24(3) (1995) 440) and Goemans and Williamson (SIAM J. Comput. 24(2) (1995) 296). We consider the on-line GSP, in which pairs of vertices arrive on-line and are needed to be connected immediately.We show that the online Min-Cost (i.e. greedy) strategy for this problem has O(log2 n) competitive ratio. The previous best algorithm was O(√nlog n) competitive (Workshop on Algorithms and Data Structures, 1993, pp. 622-633). Following this work a different (non-greedy) algorithm has been shown to achieve an O(log n) competitive ratio (Proceedings of the 29th ACM Symposium on Theory of Computing, 1997, pp. 344-353).We also consider the network connectivity leasing problem which is a generalization of the GSP. Here, edges of the graph can be either bought or leased for different costs. We provide simple randomized algorithm based on on-line generalized Steiner algorithms whose competitive ratio is within a constant factor of the best competitive algorithm for the on-line GSP.
