Heat kernel asymptotics of the subordinator and subordinate Brownian motion

For a class of Laplace exponents, we consider the transition density of the subordinator and the heat kernel of the corresponding subordinate Brownian motion. We derive explicit approximate expressions for these objects in the form of asymptotic expansions: via the saddle point method for the subordinator’s transition density and via the Mellin transform for the subordinate heat...

SecurAcath for Securing Peripherally Inserted Central Catheters: A NICE Medical Technology Guidance

Central venous catheters are commonly used to deliver therapies and to monitor patients, and require securing at the point of percutaneous entry to avoid dislodgement. SecurAcath is a catheter securement device designed for central venous catheters. The National Institute for Health and Care Excellence, as a part of its Medical Technologies Evaluation Programme, selected this...

Necessary Criterion for Approximate Recoverability

A tripartite state \(\rho _{ABC}\) forms a Markov chain if there exists a recovery map \(\mathcal {R}_{B \rightarrow BC}\) acting only on the B-part that perfectly reconstructs \(\rho _{ABC}\) from \(\rho _{AB}\). To achieve an approximate reconstruction, it suffices that the conditional mutual information \(I(A:C|B)_{\rho }\) is small, as shown recently. Here we ask what...

"Now you're competing": how historically-Black colleges and universities compete (and don't) on the Internet

No extant research has examined the web presence, web popularity, and paid adword tactics of historically-Black colleges and universities (HBCUs) compared to similar institutions. This study explores these measures and evaluates how HBCU web presence, web popularity, and paid search tactics compare to similar institutions to learn whether HBCUs are competing in one of the most...

Coaxial superposition of Bessel beams by discretized spiral axicons

BackgroundA diffractive spiral axicon can be used for the generation of a vortex beam with orbital angular momentum. The coaxial superposition of multiple vortices can generate a complex field with off-axis optical vortices. These fields are known as optical vortex lattices. In general, this superposition is done by the use of spatial light modulators. Discretization of the...

Measuring the Accessibility and Equality of Civil Justice

While, in the UK, attitudes to the criminal justice system have been routinely investigated less effort has been made to measure attitudes to the civil justice system. However, globally, there are increasingly numerous examples of studies of attitudes to civil justice. Robust standardised scales are important to establishing change and difference between groups; for example, in...

Ensemble feature learning for material recognition with convolutional neural networks

Material recognition is the process of recognizing the constituent material of the object, and it is a crucial step in many fields. Therefore, it is valuable to create a system that could achieve material recognition automatically. This paper proposes a novel approach named ensemble learning for material recognition with convolutional neural networks (CNNs). In the proposed...

A dynamic geo-based resource selection algorithm for LTE-V2V communications

The geography-based (geo-based) resource selection algorithm is one of the feasibility schemes of third-generation partnership project (3GPP). However, most researches about it ignore the impacts of boundary interference and vehicle density. Therefore, this paper firstly puts forward an enhanced geo-based resource selection algorithm (EGRSA). This algorithm can eliminate the...

Quantum character varieties and braided module categories

We compute quantum character varieties of arbitrary closed surfaces with boundaries and marked points. These are categorical invariants \(\int _S{\mathcal {A}}\) of a surface S, determined by the choice of a braided tensor category \({\mathcal {A}}\), and computed via factorization homology. We identify the algebraic data governing marked points and boundary components with the...

Diagnostic value of salivary CRP and IL-6 in patients undergoing anti-TNF-alpha therapy for rheumatic disease

IntroductionSaliva has been increasingly used as a diagnostic medium for disease detection and monitoring. The aim of this observational, prospective, pilot study was to investigate whether salivary concentrations of CRP and IL-6 correlate with those in serum and with the clinical course of a rheumatic disease.Materials and methodsNineteen patients with rheumatic disease newly...

Severity-Stratified Discrete Choice Experiment Designs for Health State Evaluations

BackgroundDiscrete choice experiments (DCEs) are increasingly used for health state valuations. However, the values derived from initial DCE studies vary widely. We hypothesize that these findings indicate the presence of unknown sources of bias that must be recognized and minimized. Against this background, we studied whether values derived from a DCE are sensitive to how well...

Image denoising with morphology- and size-adaptive block-matching transform domain filtering

BM3D is a state-of-the-art image denoising method. Its denoised results in the regions with strong edges can often be better than in the regions with smooth or weak edges, due to more accurate block-matching for the strong-edge regions. So using adaptive block sizes on different image regions may result in better image denoising. Based on these observations, in this paper, we...

Delay-based and QoS-aware packet scheduling for RT and NRT multimedia services in LTE downlink systems

Guaranteeing Quality of Service (QoS) for heterogeneous traffic is a major challenge in the Fourth Generation (4G) mobile networks. Therein, the absence of sophisticated resources allocation process at the base station jeopardizes QoS in terms of latency data transfer. It has been observed from the literature that low delay bounds might be ensured, however, at the expense of...

Inhibitory effects against α-glucosidase and α-amylase of the flavonoids-rich extract from Scutellaria baicalensis shoots and interpretation of structure–activity relationship of its eight flavonoids by a refined assign-score method

A flavonoids-rich extract of Scutellaria baicalensis shoots and its eight high content flavonoids were investigated for their inhibitory effects against α-glucosidase and α-amylase. Results show that abilities of the extract in inhibiting the two enzymes were obviously higher than those of acarbose. Moreover, inhibitory abilities of all the eight individual flavonoids against the...

A unified regularization theory: the maximum non-extensive entropy principle

Tsallis' non-extensive entropy is used as a regularization operator. The parameter ''q'' (non-extensivity parameter) has a central role in the Tsallis' thermostatiscs formalism. Here, several values of q are investigated in inverse problems, using q < 1 and q > 1. Two standard regularization techniques are recovered for special q-values: (i) q = 2 is the well known Tikhonov...

Removal of malachite green from aqueous solution using pulverized teak leaf litter: equilibrium, kinetic and thermodynamic studies

The removal of malachite green (MG) from aqueous solution using teak leaf litter powder (TLLP) was investigated. The process was influenced by initial concentration, pH and temperature of dye solution as well as TLLP dosage. Optimum removal of MG per gram of TLLP occurred at 2 g/L and at pH 6–8. Dubinin–Radushkevich and Freundlich isotherm models fit the batch adsorption data...
