Interdiffusion and grain isolation in Co/Cr thin films (1994)

In this work, interdiffusion and grain isolation in Co/Cr films have been investigated by studying the dependence of the magnetic properties on the substrate preheating temperature as well as on post-deposition annealing processes. By choosing pure Co instead of a Co-alloy, the possibility of grain isolation caused by the segregation of solute atoms from within the magnetic layer has been eliminated. It is found that both post-deposition thermal annealing and substrate preheating can effectively increase the isolation of the Co grains.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Erratum to Analytical solution to the transient phase of steady state free precession sequences. Magn Reson Med 2009;62:149-164 (2010)

When calculating the average course of the decay of RF-spoiled SSFP sequences (red curves in Fig. 9c and d), the integration contour not only enclosed the singularities on the real positive axis (red line in Fig. 9b) but, accidentally, also the two adjacent complex conjugate end points of the green cut lines. Due to their small but nonzero phase, the latter added low-frequency oscillations to the decay, which perfectly reproduced the observed nonexponential behavior, but were erroneously attributed to and explained with the dispersion of real valued singularities (Fig. 10). Taking account of that, no further changes to the article are necessary. The author regrets this oversight.
Regulation of simian virus 40 gene expression in Xenopus laevis oocytes. (1985)

Expression of the simian virus 40 (SV40) early and late regions was examined in Xenopus laevis oocytes microinjected with viral DNA. In contrast to the situation in monkey cells, both late-strand-specific (L-strand) RNA and early-strand-specific (E-strand) RNA could be detected as early as 2 h after injection. At all time points tested thereafter, L-strand RNA was synthesized in excess over E-strand RNA. Significantly greater quantities of L-strand, relative to E-strand, RNA were detected over a 100-fold range of DNA concentrations injected. Analysis of the subcellular distribution of [35S]methionine-labeled viral proteins revealed that while the majority of the VP-1 and all detectable small t antigen were found in the oocyte cytoplasm, most of the large T antigen was located in the oocyte nucleus. The presence of the large T antigen in the nucleus led us to investigate whether this viral product influences the relative synthesis of late or early RNA in the oocyte as it does in infected monkey cells. Microinjection of either mutant C6 SV40 DNA, which encodes a large T antigen unable to bind specifically to viral regulatory sequences, or deleted viral DNA lacking part of the large T antigen coding sequences yielded ratios of L-strand to E-strand RNA that were similar to those observed with wild-type SV40 DNA. Taken together, these observations suggest that the regulation of SV40 RNA synthesis in X. laevis oocytes occurs by a fundamentally different mechanism than that observed in infected monkey cells. This notion was further supported by the observation that the major 5' ends of L-strand RNA synthesized in oocytes were different from those detected in infected cells. Furthermore, only a subset of those L-strand RNAs were polyadenylated.
Intelligent-Slicing: An AI-Assisted Network Slicing Framework for 5G-and-Beyond Networks (2023)

5G-and-beyond networks are designed to fulfill the communication and computation requirements of various industries, which requires not only transporting the data, but also processing them to meet/address diverse key performance indicators (KPIs). Network Function Virtualization (NFV) has emerged to enable this vision by: (i) collecting the requirements of diverse services, using graphs of Virtual Network Functions (VNFs); and (ii) mapping these requirements into network management decisions. Because of the latter, we need to efficiently allocate computing and network resources to support the desired services, and because of the former such decisions must be jointly optimized considering all KPIs associated with supported services. Thus, this paper proposes an optimized, intelligent network slicing framework to maintain a high performance of network operation by supporting diverse and heterogeneous services, while meeting new KPIs, e.g., reliability, energy consumption, and data quality. Different from the existing works, which are mainly designed considering traditional metrics like throughput and latency, we present a novel methodology and resource allocation schemes that enable high-quality selection of radio points of access, VNF placement and data routing, as well as data compression ratios, from the end users to the cloud. Our results depict the efficiency of the proposed framework in enhancing the network performance when compared to baseline approaches that consider partial network view or fair resource allocation.

Investigation of Spectrum Signature Instrumentation (1965)

A relationship between pulse-power input to a receiver of finite bandwedth and a siustituted CW signal is derived. Experimntal data is obtained on narrow bandwidt. (optetrum analysers) and wide bancdwidth (RF-FI meters) receivers to verify the theoretical results. It is shovn that using the proposed method data collected on different bandwidth spectrum analysers can be correlated. Equations for power per unit bandwidth are also derived. The results indicate present correlation techniques are inadequate.
Magnetic Microactuators for MEMS-Enabled Ventricular Catheters for Hydrocephalus (2006)

The most common treatment for patients with hydrocephalus is the surgical implantation of a cerebrospinal fluid (CSF) shunt. Unfortunately, this device, which is critical for lowering intracranial pressure, has a substantial failure rate (40% in the first year). A leading cause of failure is the obstruction of the ventricular catheter. The goal of this project is to design a ventricular catheter that will resist occlusion through the use of micromachining and micro electro-mechanical systems (MEMS) technologies. We designed, fabricated, and tested magnetic microactuators. The theoretical results show that the fabricated microactuators can produce the force necessary to remove an adherent cellular layer grown over the actuator surface. By integrating the microactuators into the catheters, we hope to produce an improved catheter with the ability to actively combat the health-threatening occlusion process
Laser Scanning–Based Tissue Autofluorescence/Fluorescence Imaging (LS-TAFI), a New Technique for Analysis of Microanatomy in Whole-Mount Tissues (2012)

Intact organ structure is essential in maintaining tissue specificity and cellular differentiation. Small physiological or genetic variations lead to changes in microanatomy that, if persistent, could have functional consequences and may easily be masked by the heterogeneity of tissue anatomy. Current imaging techniques rely on histological, two-dimensional sections requiring sample manipulation that are essentially two dimensional. We have developed a method for three-dimensional imaging of whole-mount, unsectioned mammalian tissues to elucidate subtle and detailed micro- and macroanatomies in adult organs and embryos. We analyzed intact or dissected organ whole mounts with laser scanning-based tissue autofluorescence/fluorescence imaging (LS-TAFI). We obtained clear visualization of microstructures within murine mammary glands and mammary tumors and other organs without the use of immunostaining and without probes or fluorescent reporter genes. Combining autofluorescence with reflected light signals from chromophore-stained tissues allowed identification of individual cells within three-dimensional structures of whole-mounted organs. This technique could be useful for rapid diagnosis of human clinical samples and possibly the effect of subtle variations such as low dose radiation.
[Correlation of malabsorption of bile acids, bile lipid composition and calculi]. (1977)

&lt;p&gt;Transition metal dichalcogenides (TMDs), such as MoS2 and WS2, are promising alternative non-noble metal catalysts to drive the electrocatalytic H2 evolution reaction (HER). However, their catalytic performance is inherently limited by the small number of active sites as well as their poor electrical conductivity. Here, we grow vertically aligned 2H-WS2 on different substrates to expose their edge sites for the HER and introduce a scalable approach to tune these active sites via defect engineering. In a thermal hydrogen treatment procedure, sulfur vacancies and metallic tungsten nanoparticles are formed. The extent of desulfurization, and thus the HER activity, can be tuned via controlling the H2 annealing conditions. The obtained W/WS2-x electrocatalysts are evaluated experimentally and theoretically to arrive at a better understanding of how to modify the inherently inert 2H-WS2 for more efficient HER.&lt;/p&gt;
Chylomicron-lipid-splitting activity in homogenates of rabbit polymorphonuclear leukocytes (1965)

Evidence for hydrolysis of chylomicron-triglyceride was sought in homogenates of polymorphonuclear leukocytes obtained from rabbit peritoneal exudates. Such activity was found using chylomicra from human thoracic duct lymph. Release of fatty acid was greatest at pH 4.8 and a triglyceride concentration of 5 mm. Most of the activity was found associated with particulate fractions of the homogenate. Almost 50% of the total activity occurred in association with the granules (lysosomes) of the leukocytes. Repeated freezing and thawing of whole homogenate or its particulate fractions resulted in an increase in activity of approximately 50%. The activity was inhibited by phosphate and NaF but not by protamine or iodoacetate. It is concluded that homogenates of leukocytes contain an acid glycerolester hydrolase, which splits triglycerides of naturally occurring lipoproteins. The intracellular distribution of the activity suggests that it is at least in part lysosomal in origin.
High soluble Fas and soluble Fas Ligand serum levels before stent implantation are protective against restenosis (2011)

Percutaneous coronary intervention (PCI) represents the most important treatment of coronary artery stenosis today. But instent restenosis (ISR) is a limitation for the outcome. Fas and Fas Ligand have been implicated in apoptosis and vessel wall inflammation. Their role in ISR is not known so far. In this prospective study we studied 137 patients with stable coronary artery disease who underwent elective PCI. Blood samples were taken directly before and 24 hours after PCI. Soluble (s)Fas and sFas Ligand serum levels were measured by ELISA. Restenosis was evaluated six to eight months later either by coronary angiography or by exercise testing. During the follow-up period, 18 patients (13%) developed ISR. At baseline, patients with ISR had significantly lower median sFas, as well as sFas Ligand levels compared to patients without ISR (sFAS: ISR 492 pg/ml, no ISR 967 pg/ml, p=0.014; sFAS Ligand: ISR: 26 pg/ml, no ISR: 42 pg/ml, p=0.001). After PCI median sFas levels significantly decreased in patients with ISR compared to patients without ISR [ISR: -152 pg/ml (IQR -36 to -227), no ISR: -38 pg/ml (IQR -173 to +150 pg/ml), p=0.03]. sFas Ligand levels after PCI significantly increased in ISR patients compared to patients without ISR [ISR: 14 pg/ml (IQR -3 to +26 pg/ml), no ISR -6 pg/ml (IQR -22 to +21 pg/ml), p=0.014]. In conclusion, sFas and sFas Ligand seem to be associated with the development of ISR. Determination of serum levels before and after PCI might help identifying patients at higher risk of ISR.
Sparks of GPTs in Edge Intelligence for Metaverse: Caching and Inference for Mobile AIGC Services (2023)

Aiming at achieving artificial general intelligence (AGI) for Metaverse, pretrained foundation models (PFMs), e.g., generative pretrained transformers (GPTs), can effectively provide various AI services, such as autonomous driving, digital twins, and AI-generated content (AIGC) for extended reality. With the advantages of low latency and privacy-preserving, serving PFMs of mobile AI services in edge intelligence is a viable solution for caching and executing PFMs on edge servers with limited computing resources and GPU memory. However, PFMs typically consist of billions of parameters that are computation and memory-intensive for edge servers during loading and execution. In this article, we investigate edge PFM serving problems for mobile AIGC services of Metaverse. First, we introduce the fundamentals of PFMs and discuss their characteristic fine-tuning and inference methods in edge intelligence. Then, we propose a novel framework of joint model caching and inference for managing models and allocating resources to satisfy users' requests efficiently. Furthermore, considering the in-context learning ability of PFMs, we propose a new metric to evaluate the freshness and relevance between examples in demonstrations and executing tasks, namely the Age of Context (AoC). Finally, we propose a least context algorithm for managing cached models at edge servers by balancing the tradeoff among latency, energy consumption, and accuracy.
The Effects of Suction and Pin/Lock Suspension Systems on Transtibial Amputees’ Gait Performance (2014)

The suction sockets that are commonly prescribed for transtibial amputees are believed to provide a better suspension than the pin/lock systems. Nevertheless, their effect on amputees' gait performance has not yet been fully investigated. The main intention of this study was to understand the potential effects of the Seal-in (suction) and the Dermo (pin/lock) suspension systems on amputees' gait performance.
Himalayan black bulbuls (Hypsipetes leucocephalus niggerimus) exhibit sexual dichromatism under ultraviolet light that is invisible to the human eye (2017)

Sexual dichromatism is a key proxy for the intensity of sexual selection. Studies of dichromatism in birds may, however, have underestimated the intensity and complexity of sexual selection because they used museum specimens alone without taking colour-fading into account or only measured conspicuous visual traits in live animals. We investigated whether the Himalayan black bulbul (Hypsipetes leucocephalus nigerrimus), which is sexually monomorphic to the human eye, exhibits sexual dichromatism distinguishable by a spectrometer. We measured the reflectance (within both the human visual perceptive and the ultraviolet ranges) of two carotenoid-based parts and eight dull and melanin-based parts for each individual live bird or museum skin sampled. According to an avian model of colour discrimination thresholds, we found that males exhibited perceptibly redder beaks, brighter tarsi and darker plumage than did females. This suggests the existence of multiple cryptic sexually dichromatic traits within this species. Moreover, we also observed detectable colour fading in the museum skin specimens compared with the live birds, indicating that sexual dichromatism could be underestimated if analysed using skin specimens alone.
<title>Image and video search engine for the World Wide Web</title> (1997)

We describe a visual information system prototype for searching for images and videos on the World-Wide Web. New visual information in the form of images, graphics, animations and videos is being published on the Web at an incredible rate. However, cataloging this visual data is beyond the capabilities of current text-based Web search engines. In this paper, we describe a complete system by which visual information on the Web is (1) collected by automated agents, (2) processed in both text and visual feature domains, (3) catalogued and (4) indexed for fast search and retrieval. We introduce an image and video search engine which utilizes both text-based navigation and content-based technology for searching visually through the catalogued images and videos. Finally, we provide an initial evaluation based upon the cataloging of over one half million images and videos collected from the Web.
A USA-based registry for pulmonary arterial hypertension: 1982–2006 (2007)

The aim of this study was to define the epidemiology of World Health Organization (WHO) Group I pulmonary arterial hypertension (PAH) in a large referral centre in the USA. The Pulmonary Hypertension Connection registry, initiated in 2004, evaluated all patients in a single USA practice from 1982-2006. For comparison, the authors divided the group by incident versus prevalent cohorts, aetiology and by treatment era. In total, 578 patients (77% female) aged 48+/-14 yrs were entered. Of these, 80% had class III or IV symptoms. Over time, connective tissue disease-associated PAH increased, while referrals for HIV remained low. One-third of patients were referred on calcium channel blocker therapy even though only 4.6% had an acute response to vasodilator challenge. When compared by treatment era, there were no differences in the severity of PAH. However, survival had improved over time, with a 1-yr survival of 85% in the incident cohort. In the USA, pulmonary arterial hypertension patients are still referred to tertiary centres too late. Referral of connective tissue disease is increasing, while referral of HIV remains low. Inappropriate calcium channel blocker treatment is common. Survival rates have increased but remain low suggesting that prognosis is improving but PAH is still a progressive, fatal disease.

Forward covariance least-squares algorithm: a new method in AR spectral estimation (1981)

A new method for estimating autoregressive (AR) process coefficients for spectral estimation is introduced by minimising the average power of the forward covariance prediction error. AR spectra generated by this method are shown to have improved performance over AR spectra generated by the best alternative forward prediction error method, the Yule-Walker estimator.
Photostable and highly emissive glassy organic dots exhibiting thermally activated delayed fluorescence (2019)

Organic nanoparticles (O-dots) with a high photoluminescence quantum yield (94%) and long-lived delayed emission (3.1 μs) originating from thermally activated delayed fluorescence (TADF) were developed as glassy state particles using an oil in water emulsion under high pressure (<20 bar). The TADF glassy O-dots exhibit not only good dispersibility and high photostability in water but also good uptake properties into living cells. The glassy O-dots will open new uses as organic emitters in biological applications.
Clinical Factors Affecting Lipid Metabolism and Optimal Dose of Heparin in Preterm Infants on Parenteral Nutrition (2013)

Preterm infants receiving parenteral nutrition, particularly SGA and extremely low birth weight infants, tend to have hypertriglyceridemia. Thus, administration of 1 U/mL of heparin rather than 0.5 U/mL or none may be helpful to prevent hypertriglyceridemia in preterm infants.

Maximum likelihood speed and distance estimation for OFDM radar (2010)

A distance and speed estimation algorithm for OFDM based radar is analysed statistically. The maximum likelihood estimator is derived and compared to previous results. A connection to spectral analysis is drawn, simplifying the analysis of the estimator in question. Finally, a method to evaluate the performance of the algorithm is presented and conclusions for the structure of the OFDM signals are drawn. It is shown that the estimation algorithm works well above an SNR threshold, but rapidly degrades below.
Speech recognition method using quantisedLSP parameters in CELP-type coders (1998)

A low-complexity speech recognition method applicable to digital communication networks is proposed. A feature set suitable for speech recognition is obtained from quantised LSP parameters in CELP-type coders without reconstructing the speech signals. The authors present the effects of the speech coder on speaker-independent recognition performance, and show that the recognition accuracy of the proposed method is better than that of the recogniser using reconstructed speech signals.
