'Lauren Petrick' 'Maaike van Gerwen'] Surface sampling is a frequent task in laboratory work and field studies. Simple methods usually have low efficiency in collecting target substances from surfaces. This study developed an advanced tape-stripping approach for efficient sampling on non-absorbent surfaces. A…

Accurate and efficient calculation of alchemical free energies is a critical challenge in computational chemistry, frequently hindered by the inherent limitations of conventional Thermodynamic Integration (TI) methods. These limitations include poor phasespace overlap between discrete alchemical states, inefficient…

Efficient information sampling is crucial for human inference and decision-making, even for young children. Information sampling is also closely associated with the core symptoms of autism spectrum disorder (ASD), since both the social interaction difficulties and repetitive behaviors suggest that autistic people may…

While particulate matter (PM) instruments are widely used for air quality monitoring and policy development, there is limited research on how wind speed (U0) and contact angle (θ) affect the measurement accuracy of submicron PM, or particles with their diameters ≤ one µm (PM1). This study addresses this gap by…

Thinning is a sub-sampling technique to reduce the memory footprint of Markov chain Monte Carlo. Despite being commonly used, thinning is rarely considered efficient. For sampling convex polytopes uniformly, a highly relevant use-case in systems biology, we here demonstrate that thinning generally boosts computational…

> Abstract. The effective sample size (ESS) is widely used in samplebased simulation methods for assessing the quality of a Monte Carlo approximation of a given distribution and of related integrals. In this paper, we revisit and complete the approximation of the ESS in the specific context of importance sampling (IS).…

Background Data Envelopment Analysis (DEA) methodology is considered the most suitable approach for relative performance efficiency calculation for banks as it is believed to be superior to traditional ratio-based analysis and other conventional performance evaluations. This study provides statistical evidence on the…

'Abdul Salam'] In survey sampling, systematic sampling design has attracted survey researchers in recent years due to its simplicity of use. We introduce a modified variant of systematic sampling scheme which improves the efficiency of a recently developed diagonal systematic sampling method. The suggested modification…

We provide a narrative review on the published peer-reviewed scientific literature reporting sampler efficiency, performance and comparison studies (where two or more samplers have been assessed) in laboratory settings published between 1994 and 2021 (27 year period). This review is a follow-up to our narrative review…

In this work, we analyze alternative effective sample size (ESS) metrics for importance sampling algorithms, and discuss a possible extended range of applications. We show the relationship between the ESS expressions used in the literature and two entropy families, the R´enyi and Tsallis entropy. The R´enyi entropy is…

Kinetic models are widely used in simulating the relationship between the input space and the outcome space of a chemical process. Ignoring the computational cost, complete profiling, i.e., performing simulation at all grid points in the input space, would be the best way to understand the model, because it provides us…

The algorithm for sampling the Watt spectrum is widely recognized and is provided in Algorithm 1 for completeness. This algorithm has been incorporated into Monte Carlo software packages such as OpenMC [2] and MCNP [3]. However, the rationale behind the selection of parameters K, L, and M in Algorithm 1 remains…

Ultrasensitive, quantitative and simple tests for proteins and nucleic acids could empower analysis and disease diagnosis, but slowness of analyte capture and detection prevent it. We introduce the microfluidic sieve-detector (MSD) based on microfluidic Brownian affinity traps (BATs). A BAT is a micro-conduit coated…

Labeling efficiency is a crucial parameter in fluorescence applications, especially when studying biomolecular interactions. Current approaches for estimating the yield of fluorescent labeling have critical drawbacks that usually lead them to be inaccurate or not quantitative. We present a method to quantify…

Environmental DNA (eDNA) methodology is widely applied in the biomonitoring of organisms, but it requires the target DNA to be detected in a simple, stable, and highly sensitive manner. Detection sensitivity of eDNA measurement becomes particularly critical when monitoring species present at low abundance. In this…

'Asady Sukanya Sukumar' 'Joy J. Mammen' 'Saravanan Mullai'] This study evaluated and compared the overall equipment effectiveness (OEE), sensitivity, specificity, and efficiency of the high-end hematology analyzers, Yumizen H2500, DxH 800, DxH 900 and XN-9000 (XN-10). A total of 400 anonymized left over’s K2 EDTA whole…

Unlike the Carnot heat engine efficiency published in 1824, an isothermal efficiency derived from thermodynamics and information theory can be applied to biological systems. The original approach by Pierce and Cutler in 1959 to derive the isothermal efficiency equation came from Shannon’s channel capacity of 1949 and…

Single particle inductively coupled plasma-mass spectrometry (SP ICP-MS) has emerged as a powerful technique for characterising nanoparticles (NPs) and is increasingly used to target microparticles including microplastics (MPs). The accuracy of determining size distributions and number concentrations in SP ICP-MS is…

Collisional Brownian engines have attracted significant attention due to their simplicity, experimental accessibility, and amenability to exact analytical solutions. While previous research has predominantly focused on optimizing mean values of power and efficiency, the joint statistical properties of these performance…

Energy-poor households often compromise their thermal comfort and refrain from operating mechanical cooling devices to avoid high electricity bills. This is compounded by certain behavioral practices like retention of older, less efficient appliances, resulting in missed energy savings. Thus, the need to enhance…

Would you rather search for a line inside a cube or a point inside a square? Physics-based simulations and wet-lab experiments often have symmetries (degeneracies) that allow reducing problem dimensionality or search space, but constraining these degeneracies is often unsupported or difficult to implement in many…
