Quantitative Correlation between Hierarchical Nanofiller Structure and Rheology of Polymer/Fumed Silica Nanocomposites (2023)

Understanding the mechanical reinforcement of polymer nanocomposites (PNCs) filled with agglomerated nanofillers has attracted considerable attention in the past century, but a quantitative description of linear rheology over a wide range of time scales is still a challenge at present. In this study, the hierarchical nanofiller structure and its relationship to the rheology of fumed silica-filled poly(methyl methacrylate) nanocomposites are quantitatively investigated using transmission electron microscopy, small-angle X-ray scattering, and rheological measurements. It is suggested that the polymer entanglements dominate the short-time rheological behavior of nanocomposites, and the enhancement in the rubbery modulus is controlled by the interfacial adsorption-induced entanglements, which depend on the effective surface fractal dimension of nanofillers. At a longer time scale, the discrete agglomerates and the particle networks dominate the modulus enhancement. It was found that there is a power–law relationship between the particle network modulus and the inter-agglomerate mesh size with an exponent of −5, corresponding to a chemical dimension of 1 and rigid particle chains. A new two-phase model is suggested for the linear rheology of PNCs, including the contribution of interfacial entanglements, discrete agglomerates, and particle networks. The linear viscoelasticity of PNCs can be quantitatively described using properly determined structural parameters of particle agglomerates.

RSCM: Region Selection and Concurrency Model for Multi-Class Weather Recognition (2017)

Toward weather condition recognition, we emphasize the importance of regional cues in this paper and address a few important problems regarding appropriate representation, its differentiation among regions, and weather-condition feature construction. Our major contribution is, first, to construct a multi-class benchmark data set containing 65 000 images from six common categories for sunny, cloudy, rainy, snowy, haze, and thunder weather. This data set also benefits weather classification and attribute recognition. Second, we propose a deep learning framework named region selection and concurrency model (RSCM) to help discover regional properties and concurrency. We evaluate RSCM on our multi-class benchmark data and another public data set for weather recognition.
Drilling data of deep coal seams of the Cooper Basin: analysis and lessons learned (2018)

Deep (&amp;gt;4920 ft; &amp;gt;1500 m) coal seams of the Cooper Basin accommodate large amounts of natural gas; however, permeability of this unconventional resource is low and reservoir stimulation in prospective coal intervals is essential to achieve commercial production. This paper aims to analyse drilling data of deep coal seams of the Cooper Basin in South Australia. Drilling data obtained from mud logs are utilised to construct a drillability index (DI), in which rate of penetration is normalised by drilling factors, making DI more sensitive to coal rock strength. Analysis of DI and gas show information provides a preliminary screening tool for studying prospective deep coal seams, before performing in-depth reservoir characterisation and production tests. The decline in DI with depth is attributed to a compaction effect that makes deeper coal seams more difficult to drill through compared with shallow seams. The existence of a fracture network can reduce coal rock strength and consequently DI may increase. The increase in DI may be indirectly related to fluid flow characteristics of the coal seam helping in identifying prospective coal intervals. The DI is also affected by other factors and, hence, should be used in combination with reservoir information to yield conclusive indications. Gas show information and DI results were utilised to indicate the effectiveness of dewatering operation and hydraulic fracture confinement in the wells drilled in the Klebb area located in the Weena Trough.
Gate-Tunable Spin-Charge Conversion and the Role of Spin-Orbit Interaction in Graphene (2016)

The small spin-orbit interaction of carbon atoms in graphene promises a long spin diffusion length and the potential to create a spin field-effect transistor. However, for this reason, graphene was largely overlooked as a possible spin-charge conversion material. We report electric gate tuning of the spin-charge conversion voltage signal in single-layer graphene. Using spin pumping from an yttrium iron garnet ferrimagnetic insulator and ionic liquid top gate, we determined that the inverse spin Hall effect is the dominant spin-charge conversion mechanism in single-layer graphene. From the gate dependence of the electromotive force we showed the dominance of the intrinsic over Rashba spin-orbit interaction, a long-standing question in graphene research.
Revolutionizing Optical Wireless Communications via Smart Optics (2022)

The heterogeneity of optical wireless networks (OWNs) has expanded over decades in terms of services, node densities, mobility requirements, bandwidth needs, responsiveness, and physical device profile. Consequently, incorporating dynamic reconfigurability into future OWNs can satisfy their diverse realm of objectives. Towards this end, we provide our vision for the potential gains of integrating tunable optical elements in OWNs reflected in energy consumption reduction, coverage customization, data transfer rate boosting, highly accommodating multiple access schemes, enhancing physical layer security, supporting simultaneous services, and interference reduction. Finally, we speculate a roadmap for future research directions in tunable optics aided OWNs and the associated challenges with their deployment and operation.
Tautomeric pyridines. Part X. Effects of substituents on pyridone–hydroxypyridine equilibria and pyridone basicity (1968)

The tautomeric equilibria of dimethyl 4-hydroxypyridine-2,6-dicarboxylate, and of 3–5-diethoxycarbonyl-2-methyl, 3,5-dinitro- and 2,3,5-trichloro-4-pyridone have been investigated. Substituent groups in the α-positions affect the tautomerism much more than groups in the β-positions. The protonation behaviour of pyridones in strong acids is discussed. The base strengths of pyridones can be predicted from equation (2), and such calculated values are used to estimate for tautomeric derivatives KT values which are compared with experimental data.
Structure and Properties of Albumin Tokushima and Its Proteolytic Processing by Cathepsin B In Vitro1 (1986)

Albumin Tokushima is a Japanese genetic variant of human serum albumin. Two homozygous and 6 heterozygous subjects with this variant were found in a family. Albumin Tokushima was purified from sera of the homozygous subjects. Its amino acid composition and amino-terminal sequence were determined and compared with those of a normal serum albumin. Albumin Tokushima with the amino-terminal sequence of Arg-Gly-Val-Phe-His-Arg-Asp-Ala-His-Lys-Ser-Glu-Val-Ala-His-Arg-Phe-Lys- Asp- Leu-Gly-Glu-Glu-Asn-Phe was found to be the same abnormal proalbumin as proalbumin Lille (Abdo, Y. et al. (1981) FEBS Lett. 131, 286-288). The isoelectric points of albumin Tokushima were pH 4.70 and 4.90 as compared with pH 5.05 and 5.25 of a normal serum albumin. Albumin Tokushima was converted to normal serum albumin by purified cathepsin B in vitro. Albumin Tokushima can bind Ni2+ at 4 degrees C but binds little at 37 degrees C.
How Many Americans Will Be Eligible for Biliary Lithotripsy? (1989)

Extracorporeal shock wave lithotripsy has received increasing attention as a possible alternative to cholecystectomy. Good data, however, are not available on what percentage of the 500,000 Americans presently undergoing cholecystectomy annually might be eligible for extracorporeal shock wave lithotripsy. Therefore, we studied 100 consecutive adult patients undergoing cholecystectomy and applied present exclusion criteria to determine their suitability for extracorporeal shock wave lithotripsy. In each patient, preoperative history and operative findings were reviewed. Gallstone size and number were recorded, and cholesterol content and radiopacity were determined. Cholesterol stones were found in 74 patients, pigment stones in 21, and acalculous cholecystitis in 5. Of the 100 patients, only 19 (19%) had no exclusion criteria and, thus, would have been eligible for extracorporeal shock wave lithotripsy. These data suggest that approximately 95,000 Americans a year will be candidates for shock wave biliary lithotripsy.

Android Forensics: Investigating Social Networking Cybercrimes against Man-in-the-Middle Attacks (2016)

Cyber-attacks are on the rise due to the increased usage of social networking application's built-in Android devices via Wi-Fi connections, which has resulted in privacy issues. Several studies have been conducted to investigate Android phones, however, none of these have proposed a comprehensive Android investigation method, which begins with a Man-in-the-Middle attack and ending in a criminal investigation. The purpose of this research is to propose an Android forensics framework against such Wi-Fi attacks, using advanced forensic tools, such as the Cellebrite Universal Forensic Extraction Device and the Oxygen. This will assist the researcher to prove the suggested arguments in the following: 1. To implement guidelines for the forensic examiners, especially for those new in the field of forensics, and 2. To guide Android and social networking application developers to enhance the level of security. Furthermore, this study recommends the best data extraction methods designed for Android devices.

Safety of Intermittent Pringle Maneuver Cumulative Time Exceeding 120 Minutes in Liver Resection (2011)

This study shows that hepatectomies done with intermittent clamping exceeding 120 minutes are as safe as those performed with shorter one despite more complex tumor presentations. This seems encouraging the diffusion of procedures done in 1 stage for extensive liver diseases despite the prolonged clamping time.

Effect of methylxanthine derivatives on T cell activation. (1992)

In a Phase I-II trial examining the effect of prophylactic administration of pentoxifylline (PTX) on bone marrow transplant-associated morbidity, there was an apparent reduction in the incidence and severity of acute graft-versus-host disease. To determine if PTX might be directly immunosuppressive, its effects on T cell activation and proliferation were examined. PTX and several cogeners were found to directly suppress T cell proliferation in response to phytohemagglutinin, to allogeneic cells in a mixed leukocyte reaction, and to cross-linking the CD3 complex. The effects were dose-related and associated with suppression of secretion of tumor necrosis factor-alpha (TNF alpha). However, the inhibition of proliferation was not solely due to this effect since adding excess recombinant TNF alpha did not restore the proliferative response. These data suggest that PTX may be clinically useful in suppressing allogeneic reactions in bone marrow transplantation.
Short-term real-world outcomes following intravitreal brolucizumab for neovascular AMD: SHIFT study (2021)

The results of the SHIFT study indicate that switch to brolucizumab may represent a treatment option in patients with nAMD poorly responsive to other anti-VEGF agents. Further long-term analyses appear prudent to assess efficacy and safety of brolucizumab in a routine clinical setting.
Agile gesture recognition for capacitive sensing devices: adapting on-the-job (2023)

Automated hand gesture recognition has been a focus of the AI community for decades. Traditionally, work in this domain revolved largely around scenarios assuming the availability of the flow of images of the operator's/user's hands. This has partly been due to the prevalence of camera-based devices and the wide availability of image data. However, there is growing demand for gesture recognition technology that can be implemented on low-power devices using limited sensor data instead of high-dimensional inputs like hand images. In this work, we demonstrate a hand gesture recognition system and method that uses signals from capacitive sensors embedded into the etee hand controller. The controller generates real-time signals from each of the wearer's five fingers. We use a machine learning technique to analyse the time-series signals and identify three features that can represent 5 fingers within 500 ms. The analysis is composed of a two-stage training strategy, including dimension reduction through principal component analysis and classification with K-nearest neighbour. Remarkably, we found that this combination showed a level of performance which was comparable to more advanced methods such as supervised variational autoencoder. The base system can also be equipped with the capability to learn from occasional errors by providing it with an additional adaptive error correction mechanism. The results showed that the error corrector improve the classification performance in the base system without compromising its performance. The system requires no more than 1 ms of computing time per input sample, and is smaller than deep neural networks, demonstrating the feasibility of agile gesture recognition systems based on this technology.
Post‐transcriptional processing of the LEE4 operon in enterohaemorrhagic Escherichia coli (2012)

This article appeared in Mol Microbiol (2009) 71(2): 273–90. In the article by Lodato and Kaper (2009) there is an error in the description of one of the gene fusions constructed. On page 278, left column, line 12, instead of ‘For this purpose, sepL–espADB genes were cloned . . . ’ it should read ‘For this purpose, sepL–espAD genes were cloned . . . ’. Similarly, on page 286, under Plasmid constructions, line 15 of the first paragraph, instead of ‘. . . the sepLespADB sequence was amplified . . . ’ it should read ‘. . . the sepL–espAD sequence was amplified . . . ’. This fusion is correctly described in the legend to Fig. 5 and elsewhere in the paper. In summary, the gene fusion contained in plasmid pPL1 carries the genes sepL, espA and espD but not espB.
Testosterone And Androgen Receptor Responses To Resistance Exercise (2005)

L-carnitine supplementation has been shown to affect androgenic hormonal responses to chronic exercise stress in animal studies. In humans, resistance exercise-induced muscle damage and soreness decreased following L-carnitine supplementation. This response was potentially due to enhanced hormonal receptor availability for binding interactions; however, this hypothesis has not been directly tested. PURPOSE To examine the effects of L-carnitine supplementation on testosterone (T) and androgen receptor (AR) responses to resistance exercise. METHODS Ten recreationally weight-trained men (mean±SD age: 22±1 y, mass: 86.3±15.3 kg, height: 181±11 cm) supplemented with L-carnitine (2g d−1) or placebo for 21-d followed by an acute heavy resistance exercise challenge (4 sets of 10 repetitions each of back squat, bench press, bent over row, and shoulder press exercises) in a randomized, balanced, repeated measures design. T concentrations were determined from blood samples obtained preexercise, immediately post-exercise, and serially every 10-min for 60-min thereafter. AR content was evaluated from skeletal muscle biopsies of the vastus lateralis obtained 48 to 72-h pre- and 1-h post-resistance exercise. RESULTS L-carnitine supplementation significantly (p < 0.05) increased T concentrations pre-exercise, at 0-, 30-, 40-, 50-, and 60-min post-exercise, and T integrated area under the curve. L- carnitine supplementation significantly increased pre-exercise AR content (12.9±5.9au for L-carnitine vs. 11.2±4.0au for placebo; p < 0.05). Post-exercise AR content was significantly greater than baseline during the placebo trial only (11.2±4.0au preexercise vs. 12.9±6.3au post-exercise; p < 0.05); however, post-exercise AR content was not different between L-carnitine and placebo (11.8±3.8au vs. 12.9±6.3au, respectively; p > 0.05). CONCLUSIONS L-carnitine supplementation up-regulated AR content per-exercise and increased T concentrations post-exercise. These responses may support T and AR interactions and promote recovery from resistance exercise.
Information filtering and query indexing for an information retrieval model (2009)

In the information filtering paradigm, clients subscribe to a server with continuous queries or profiles that express their information needs. Clients can also publish documents to servers. Whenever a document is published, the continuous queries satisfying this document are found and notifications are sent to appropriate clients. This article deals with the filtering problem that needs to be solved efficiently by each server: Given a database of continuous queries db and a document d , find all queries q ∈ db that match d . We present data structures and indexing algorithms that enable us to solve the filtering problem efficiently for large databases of queries expressed in the model AWP . AWP is based on named attributes with values of type text, and its query language includes Boolean and word proximity operators.
A Multi-Slice Dual Layer MR-Compatible Animal PET System (2009)

A multi-slice depth-of-interaction (DOI) MR-compatible PET system for imaging small animals such as mice or rats was developed and tested It employs DOI block detectors made of mixed lutetium silicates (MLSs), optical fibers, and multi-channel position sensitive photo-multiplier tubes (PSPMTs). The size of a single MLS was 2.5 mm times 3.5 mm times 3.5 mm and eight MLSs were combined to form a DOI block detector using the Anger principle and connected to four optical fibers with light guides. Thirty-two sets of block detectors were arranged in a 51 mm diameter circular ring. The scintillation light signals from the DOI detectors are read from the side of the detector ring. The configuration makes the diameter of the detector ring small and easy to use in the small imaging area of the MRI. Position histograms showed good separation for all block detectors. The timing resolution was 6 ns FWHM. The measured transaxial spatial resolution was 2.8 mm FWHM at the center of the image and the axial resolution was 3 mm FWHM. Sensitivity was around 0.23% at the center of the axial field of view (FOV). Simultaneous imaging of PET and MRI was also tested using a 0.15 T permanent magnet system with a 30-mm FOV. The detector part of the PET system was set inside the gradient coil of the MRI system and the RF coil was positioned inside the FOV of the PET system. No difference was found in the PET images among outside MRI, inside MRI without gradient and RF, and inside MRI with the gradient and the RF sequences. Also there is no noticeable change of the MRI images with and without the detector ring of the PET system. We also successfully obtained simultaneously measured rat brain with the PET and MRI. These results indicate that the developed MR-compatible PET system can be used for simultaneous measurements with an MRI system.
Does the Application of Constraint-Induced Movement Therapy During Acute Rehabilitation Reduce Arm Impairment After Ischemic Stroke? (2000)

A clinical trial of CIM therapy during acute rehabilitation is feasible. CIM was associated with less arm impairment at the end of treatment. Long-term studies are needed to determine whether CIM early after stroke is superior to traditional therapies.
Smelling fit: scent marking exposes parasitic infection status in the banded mongoose (2017)

Preference for uninfected mates is presumed beneficial as it minimizes one's risk of contracting an infection and infecting one's offspring. In avian systems, visual ornaments are often used to indicate parasite burdens and facilitate mate choice. However, in mammals, olfactory cues have been proposed to act as a mechanism allowing potential mates to be discriminated by infection status. The effect of infection upon mammalian mate choice is mainly studied in captive rodents where experimental trials support preference for the odors of uninfected mates and some data suggest scent marking is reduced in individuals with high infection burdens. Nevertheless, whether such effects occur in nonmodel and wild systems remains poorly understood. Here, we investigate the interplay between parasite load (estimated using fecal egg counts) and scent marking behavior in a wild population of banded mongooses <i>Mungos mungo</i>. Focusing on a costly protozoan parasite of the genus <i>Isospora</i> and the nematode worm <i>Toxocara</i>, we first show that banded mongooses that engage in frequent, intensive scent marking have lower <i>Isospora</i> loads, suggesting marking behavior may be an indicator trait regarding infection status. We then use odor presentations to demonstrate that banded mongooses mark less in response to odors of opposite sexed individuals with high <i>Isospora</i> and <i>Toxocara</i> loads. As both of these parasites are known to have detrimental effects upon the health of preweaned young in other species, they would appear key targets to avoid during mate choice. Results provide support for scent as an important ornament and mechanism for advertising parasitic infection within wild mammals.
