Novel carbon capture and utilisation technologies (2018)

The report offers a simplified system analysis of service delivery, which highlights a few key features. 1) Using C-rich synthetic fuels requires the use of large amounts of Renewable Energy Sources (RES) and other carbon-free energies – much larger than what is required when RES electricity or green-hydrogen is used directly for consumption. 2) Such a decrease in efficiency in the use of RES may be acceptable in the provision of: a) C-rich synthetic fuels to power long-range aircraft and long-haul ships ; and/or b) long-term storage and long- range transport of defossilised energy to compensate for the intermittency of RES. 3) For such uses, CCU-based solutions should be assessed in comparison with other alternative technologies that are beyond the scope of this report.
Memristor devices for use in neuromorphic systems (2016)

This paper describes the fabrication and characterization process used to develop memristors that are strong candidates for use in neuromorphic systems. A common approach for the development of memristor-based neuromorphic circuits is to store synaptic weight values within memristors as resistance values. This requires use of the continuous resistance range available in the memristors to store the weight matrix produced by a learning algorithm. More specifically, these devices will be used in systems that implement supervised learning algorithms such as single and multilayer perceptrons. It is important to be able to iteratively program a target resistance through a number of feedback controlled voltage pulses as opposed to abruptly switching the device between two binary states. This paper shows how TiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> memristor devices placed in a crossbar arrangement are capable of implementing Boolean logic functions using a perceptron algorithm. Resistances within a memristor crossbar can be tuned and reconfigured so that a neuron circuit based on this crossbar can represent multiple different functions.
Carbamate and N-Pyrimidine Mitigate Amide Hydrolysis: Structure-Based Drug Design of Tetrahydroquinoline IDO1 Inhibitors (2021)

Indoleamine-2,3-dioxygenase-1 (IDO1) has emerged as an attractive target for cancer immunotherapy. An automated ligand identification system screen afforded the tetrahydroquinoline class of novel IDO1 inhibitors. Potency and pharmacokinetic (PK) were key issues with this class of compounds. Structure-based drug design and strategic incorporation of polarity enabled the rapid improvement on potency, solubility, and oxidative metabolic stability. Metabolite identification studies revealed that amide hydrolysis in the D-pocket was the key clearance mechanism for this class. Strategic survey of amide isosteres revealed that carbamates and <i>N</i>-pyrimidines, which maintained exquisite potencies, mitigated the amide hydrolysis issue and led to an improved rat PK profile. The lead compound <b>28</b> is a potent IDO1 inhibitor, with clean off-target profiles and the potential for quaque die dosing in humans.
Measurement of Work Function of Practical Fluorescent Lamp Electrodes with Emissive Oxides (2005)

In this paper we propose a method for measuring work function of practical fluorescent lamp electrodes with emissive oxides. The work function measurement is based on the matching between the zero-field thermionic emission currents and various dc lamp currents set in a normal glow discharge by means of a lamp voltage monitoring procedure with an electrode-heating device for thermionic emission measurement. Measuring the work function of practical fluorescent lamp electrodes is a promising approach because changes that occur in the work function of aged-lamp electrodes in some lighting systems will be helpful in evaluating the system. The paper points out the doubtful approach of taking a rather small value of the Richardson constant. To solve this issue, a temperature-dependent work function is introduced. In the first stage of the paper, the Richardson constant is taken as the theoretical value. As a result, work function φ[eV] of a fluorescent lamp electrode halfway through its lamp life was measured and given as: φ=0.80+1.36×10-3T (computed from equation with T2) where T was the electrode temperature [K].Second, an attempt is made to measure a temperature-dependent work function taking a realistic value of the Richardson constant. The smaller the value of the Richardson constant, the smaller the estimated work function is. Finally, the paper examines how to take a realistic value of the Richardson constant.
Regeneration of gratings by post-H<inf>2</inf> loading (2011)

Regeneration of two types of gratings is demonstrated using post-hydrogen loading. This increases the flexibility of the regeneration process by allowing access to gratings that are written with hydrogen and also reducing the demands for immediate regeneration after grating writing.
A Quick Crash Detection Method for IKE (2010)

This document describes an extension to the IKEv2 protocol that allows
for faster detection of SA desynchronization using a saved token.
When an IPsec tunnel between two IKEv2 peers is disconnected due to a
restart of one peer, it can take as much as several minutes for the
other peer to discover that the reboot has occurred, thus delaying
recovery. In this text we propose an extension to the protocol, that
allows for recovery immediately following the restart.
Apparatus and methods for splicing conduits and hoses subsea (2023)

A hose connection system comprises a body including an internal cavity and a port in fluid communication with a portion of the internal cavity. In addition, the system comprises a hose end fitting positioned in the cavity. The hose end fitting includes an inner tubular member and an outer tubular member concentrically disposed about the inner tubular member. The outer tubular member includes a plurality of circumferentially spaced axial slits. Further, the system comprises a plurality of wedge members arranged circumferentially about the outer tubular member. Still further, the system comprises an annular piston movably disposed within the internal cavity of the body. An end of the piston has an inner frustoconical surface that slidingly engages the plurality of wedge members. The piston is configured to move axially through the body and compress the wedge members and the outer tubular member radially inward.
A Multiple Narrow Band Antenna for Detection of Discharge‐Emitted Electromagnetic Waves for Insulation Diagnostic (2020)

Partial Discharge (PD) detection is an effective tool to diagnose the insulation condition of high voltage (HV) equipment. Among detection methods of PD, the ultra‐high frequency (UHF) method is distinguished by high sensitivity and safety operation. However, the UHF band includes many communication and broadcasting line spectral frequencies, which can be interference against the UHF method. From the point of view of the reduction of interferences, the authors proposed the multiple narrow band (MNB) antenna, which can detect PD signals with high sensitivity and eliminate the line spectral noise frequencies. In this paper, a new MNB antenna was evaluated based on fundamental properties and fabricated, then applied to detect discharge signals emitted from breakdown phenomena. The results demonstrated that the fabricated MNB antenna had a good omnidirectional radiation pattern and similar sensitivity with a standard wide‐band Horn antenna. © 2020 Institute of Electrical Engineers of Japan.

Decreased sensitivity of old and progeric human fibroblasts to a preparation of factors with insulinlike activity. (1981)

To determine whether old cells have a reduced response to a preparation of factors from human plasma with insulinlike activity (ILA), we analyzed the response to ILA of early and late passage human fibroblasts from young, old, and progeric donors in the acute stimulation of [3H]2-deoxy-D-glucose (2dG) uptake and the delayed stimulation of [3H]thymidine (TdR) incorporation into DNA. The ILA concentration required to produce equivalent, relative stimulation of TdR incorporation was increased two- to three-fold in late passage cells and cells from old and progeric donors (P less than 0.01). 50 and 95% of maximal stimulation (ILA50, ILA95) was achieved by 0.26 +/- 0.07 and 1.38 +/- 0.13 ng insulin equivalents/ml (mean +/- SD) respectively, in cells from young adults at early passage. Corresponding values were 0.54 +/- 0.05 and 2.90 +/- 0.25 in cells from old donors; greater than 0.9 +/- 0.1 and greater than 3.1 +/- 0.1 in cells from a 9-yr-old progeric donor; and 0.4 +/- 0.05 and 1.1 +/- 0.04 in cells from normal children (9-13 yr). For two cell strains from young adults, ILA50 and ILA95 were 0.30 +/- 0.02 and 1.0 +/- 0.3 ng eq/ml at 30% of their in vitro lifespan completed (%LC) and these values increased at rates of 0.005 ng eq/ml per %LC and 0.04 ng eq/ml per %LC, respectively. The mean stimulation of 2dG uptake ratio (ILA/control) decreased from early to late passage from 2.1 +/- 0.6 to 1.3 +/- 0.1 in young adult donors (P less than 0.05), but there were no significant differences between young and old donors at either early or late passage. The mean stimulation ratio in progeric cells (1.2 +/- 0.2) did not change with in vitro passage, but was significantly lower than that of age-matched normal cells (2.1 +/- 0.8, P less than 0.001). In progeria cells, the reduced stimulation of 2dG uptake upon addition of ILA was due to an increased basal rate of uptake (0.19 +/- 0.01 pmol [3H]2dG/min per mg protein vs. 0.13 +/- 0.01 in age-matched normal cells), and not to a decline in the maximal rate of uptake (0.26 +/- 0.01 vs. 0.27 +/- 0.02, respectively). Similar results were found for in vitro aging in cells from an old donor.
Intracellular activities of sodium and potassium (1978)

The intracellular contents of Na+ and K+ appear to modulate a variety of cellular and tissue functions, including transepithelial transport. However these total ionic contents appear to consist of heterogeneous populations of Na+ and K+. No more than a few percent of intracellular Na+ and K+ appear bound. Thus, the heterogeneity of the intracellular ionic contents must reflect subcellular compartmentalization. Recent technical advances in the preparation and use of ion-selective microelectrodes have permitted progress in defining the possible sites of such intracellular compartmentalization. Furthermore, intracellular recording with microelectrodes and micropipettes now provides a technique with which to directly monitor the chemical activities of Na+ and K+ within the cytoplasm as a function of the state of transepithelial transport. This approach has already provided information necessitating a reexamination of certain classical concepts of transport physiology.
Class III beta-tubulin, drug resistance and therapeutic approaches in cancers (2014)

Class III beta-tubulin is one of the critical proteins associated with microtubule assembly, important to many cellular functions including mitochondrial respiration and intracellular trafficking. Widely regarded as a specific neuronal marker in developmental neurobiology and stem cell research, it is also highly expressed in a wide range of tumors of both neuronal and non-neuronal origin. The expression of class III beta-tubulin is tightly controlled at multiple levels with tissue-dependent mechanisms of regulation. For instance, class III beta-tubulin expression is under the control of estrogens in breast cancer cells but is influenced by exposure to hypoxia and poor-nutrient supply in ovarian cancer. In some but not all cancers, class III beta-tubulin expression is purely a prognostic biomarker, predicting poor outcome of patients regardless of chemotherapy treatment. Moreover, the expression of class III beta-tubulin does not confer an aggressive phenotype by itself. Instead, class III beta-tubulin functions like a cytoskeletal gateway, which enhances the incorporation of pro-survival kinases into the cytoskeleton and protects them from degradation. The associations of class III beta-tubulin with survival kinase PIM-1, RNA-binding protein HuR, microRNAs are examples highlighting the functional complexity of this protein. The utility of class III beta-tubulin as a prognostic biomarker can also greatly improve if combined with these pro-survival partners. Subsequently, pharmacogenetic approaches, designed to counteract and target these pathways and associated-factors concurrently, might lead to better therapies and prognostic tools for class III beta-tubulin expressing cancers.

Preservative solution that stabilizes erythrocyte morphology and leukocyte viability under ambient conditions (2017)

The deterioration of whole blood ex vivo represents a logistical hurdle in clinical and research settings. Here, a cocktail preservative is described that stabilizes leukocyte viability and erythrocyte morphology in whole blood under ambient storage. Neutrophil biostabilization was explored using a sophisticated microfluidic assay to examine the effectiveness of caspase inhibition to stabilize purified neutrophils. Following 72 h ambient storage, neutrophils remained fully functional to migrate towards chemical cues and maintained their ability to undergo NETosis after stimulation. Furthermore, stored neutrophils exhibited improved CD45 biomarker retention and reduced apoptosis and mortality compared to untreated controls. To stabilize erythrocyte morphology, a preservative solution was formulated using Taguchi methods of experimental design, and combined with the caspase inhibitor to form a whole blood cocktail solution, CS<sub>WB</sub>. CS<sub>WB</sub> was evaluated in blood from healthy donors and from women with metastatic breast cancer stored under ambient conditions for 72 h. CS<sub>WB</sub>-treated samples showed a significant improvement in erythrocyte morphology compared to untreated controls. Leukocytes in CS<sub>WB</sub>-treated blood exhibited significantly higher viability and CD45 biomarker retention compared to untreated controls. This 72 h shelf life under ambient conditions represents an opportunity to transport isolates or simply ease experimental timelines where blood degradation is problematic.
A robust and automatic face tracker dedicated to broadcast videos (2005)

Because of their lack of rules, general broadcast videos are more difficult to analyze than news or sport videos. To retrieve human interventions in this context, a robust face tracker is needed. The approach we investigate for face tracking combines three main modules that are a face detector, a region-based tracker and an eye tracker. The region-based tracker relies on a robust parametric motion estimation technique. The eye tracker is based on a Kalman filter. The analysis of the coherence of the trackers output provides an efficient way to detect profile positions and tracking errors. We have thus defined an entirely automatic tracker, able to manage several appearing/disappearing faces, without any a priori knowledge on the image sequence. Experimental results on broadcast videos demonstrate its efficiency to deal with large and rapid motions, occlusions and faces in profile position.
Massive Retroperitoneal Angiomyolipoma: A Lesion That May Be Confused with Well-Differentiated Liposarcoma (1989)

A benign massive retroperitoneal lipomatous tumor is described. The tumor, from a 72-year-old woman with increasing abdominal girth, consisted of a mixture of mature lipocytes, smooth muscle cells, and thick-walled medium-size blood vessels. Although the tumor focally involved the uterine serosa, suggesting the possible diagnosis of uterine leiomyoma with fatty change, the authors think that, because the bulk of the tumor was located in the retroperitoneum and because the tumor contained characteristic thick-walled blood vessels from which smooth muscle cells radiated, this tumor would be best classified as a retroperitoneal angiomyolipoma. Although both angiomyolipomas and leiomyomas with fatty change presenting as large retroperitoneal tumors are rare, and therefore are not well-recognized by surgical pathologists, they are benign and must be distinguished from liposarcomas.
Crystal and molecular structure of polymeric MeSHgO2CMe and MeSHgO2CMe,C5H5N and the tetranuclear complex (ButS)4Cl4Hg4(C5H5N)2 (1978)

Crystals of methanethiolatomercury(II) acetate are monoclinic, P 21/c, with a 5.292(2), b 15.912(7), c 7.086(2) ?, ß 92.96(3)°, Z 4, and its pyridine complex MeSHgO2CMe,C5H5N is monoclinic, P21/n, with a 10.093(3), b 7.026(2), c 15.350(5) ?, ß 105.01(3)°, Z4. Both structures are based on a polymeric chain (-Hg-SMe-)n with coordinated acetate groups. In MeSHgO2CMe the chains are linked into sheets by bridging acetate groups, and in the pyridine complex the chains are isolated with pyridine and acetate coordination at each mercury. Crystals of (ButS)4Cl4Hg4(C5H5N)2 are triclinic, Pi, with a 14.399(6), b 9.893(6), c 9.597(5) ?, a 121.82(1), ß 102.52(4), ? 102.94(4)°, and Z 1. The structure is based on a tetranuclear grouping of mercury atoms bridged by chloride and thiolate species and centrosymmetric about the origin. There are two mercury environments 'Hg(µ-SBut)2ClN' and 'Hg(µ-SBut)2(µ-Cl)2' with the dichloro bridge linking two equivalent mercury atoms on opposite sides of an (-Hg-SBut-)4 ring.

Chirality enables unusual optical force (presentation video) (2014)

Light can exert radiation pressure on any object it encounters and that resulting optical force can be used to manipulate particles. It is natural to expect that light should push a particle forward. However, our results indicate that a lateral force can be induced in a direction perpendicular to that of the incident photon momentum if a chiral particle is placed above a substrate that does not break any left-right symmetry. Analytical theory shows that the coupling between structural chirality and the light reflected from the substrate surface induces this sideway force that pushes chiral particles with opposite handedness in opposite directions.
Learning Motion Priors for 4D Human Body Capture in 3D Scenes (2021)

Recovering high-quality 3D human motion in complex scenes from monocular videos is important for many applications, ranging from AR/VR to robotics. However, capturing realistic human-scene interactions, while dealing with occlusions and partial views, is challenging; current approaches are still far from achieving compelling results. We address this problem by proposing LEMO: LEarning human MOtion priors for 4D human body capture. By leveraging the large-scale motion capture dataset AMASS, we introduce a novel motion smoothness prior, which strongly reduces the jitters exhibited by poses recovered over a sequence. Furthermore, to handle contacts and occlusions occurring frequently in body-scene interactions, we design a contact friction term and a contact-aware motion infiller obtained via per-instance self-supervised training. To prove the effectiveness of the proposed motion priors, we combine them into a novel pipeline for 4D human body capture in 3D scenes. With our pipeline, we demonstrate high-quality 4D human body capture, reconstructing smooth motions and physically plausible body-scene interactions. The code and data are available at https://sanweiliti.github.io/LEMO/LEMO.html.
Uplink VoIP Support for 3GPP EUTRA (2007)

Evolved UTRA (EUTRA) is currently under study by 3GPP standards organizations as a long term evolution (LTE) for current generation universal terrestrial radio access (UTRA) networks. One of the key aspects of EUTRA wireless systems will be providing voice services in packet domain using voice over IP (VoIP). This paper provides system simulation results evaluating uplink VoIP capacity for EUTRA. Simulations indicate that if efficient control signaling and scheduling mechanisms are in place, EUTRA systems can support 80 to 130 Erlangs of VoIP traffic per sector in a 1.08 MHz spectrum allocation as part of a 5 MHz LTE carrier.
Obesity-Induced Changes in Adipose Tissue Microenvironment and Their Impact on Cardiovascular Disease (2016)

Obesity is causally linked with the development of cardiovascular disorders. Accumulating evidence indicates that cardiovascular disease is the collateral damage of obesity-driven adipose tissue dysfunction that promotes a chronic inflammatory state within the organism. Adipose tissues secrete bioactive substances, referred to as adipokines, which largely function as modulators of inflammation. The microenvironment of adipose tissue will affect the adipokine secretome, having actions on remote tissues. Obesity typically leads to the upregulation of proinflammatory adipokines and the downregulation of anti-inflammatory adipokines, thereby contributing to the pathogenesis of cardiovascular diseases. In this review, we focus on the microenvironment of adipose tissue and how it influences cardiovascular disorders, including atherosclerosis and ischemic heart diseases, through the systemic actions of adipokines.
Toward a DNA-Based Archival Storage System (2017)

Storing data in DNA molecules offers extreme density and durability advantages that can mitigate exponential growth in data storage needs. This article presents a DNA-based archival storage system, performs wet lab experiments to show its feasibility, and identifies technology trends that point to increasing practicality.
Characterization of inductively coupled plasma etched surface of GaN using Cl2/BCl3 chemistry (2001)

We have investigated plasma-induced damage of the inductively coupled plasma (ICP) etched surface of n-type GaN using Cl2/BCl3 chemistry. The surface morphology of the etched GaN under different plasma conditions is analyzed by atomic force microscopy. X-ray photoelectron spectroscopy is used to correlate the chemical changes induced by plasma etching of the GaN surface. We have carried out photoluminescence measurements of etched GaN surfaces subjected to varying ICP conditions. The intensity of the band-edge and yellow luminescence transitions was used to evaluate the damage introduced into the semiconductor during dry etching.
Quality assessment for super-resolution image enhancement (2006)

A typical image formation model for super-resolution (SR) introduces blurring, aliasing, and added noise. The enhancement itself may also introduce ringing. In this paper, we use subjective tests to assess the visual quality of SR-enhanced images. We then examine how well some existing objective quality metrics can characterize the observed subjective quality. Even full-reference metrics like MSE and SSIM do not always capture visual quality of SR images with and without residual aliasing.
