Estimation of finite population variance using auxiliary information in sample surveys
Statistica, 2014 This paper addresses the problem of estimating the finite population variance using auxiliary information in sample surveys. Motivated by (Singh and Vishwakarma, 2009) some estimators of finite population variance have been suggested along with their ...

Advanced Science, EarlyView.Deterministic crypt fission is achieved in intestinal organoids using photopatternable hydrogels with spatiotemporal control. Daughter‐crypt symmetry is shown to depend on parent‐crypt geometry and epithelial curvature, while myosin‐dependent mechanosensing links tissue shape to regenerative outcomes.

The arithmetic-geometric mean inequality (I)
, 2013 The arithmetic-geometric mean inequality: √ab ≤ (a+b)/2, for a,b ≥ 0. The figure shows that (a+b)²-(a-b)²=4ab, therefore √ab = √[(a+b)²-(a-b)²]/4 ≤ √[(a+b)²]/4 = (a+b)/2Ensino Médio ...

On J.M. Keynes' The principal averages and the laws of error which lead to them: refinement and generalisation [PDF]
Keynes (1911) derived general forms of probability density functions for which the “most probable value” is given by the arithmetic mean, the geometric mean, the harmonic mean, or the median.

Ultrahigh Interfacial Thermal Conductance across GaN/BAs Interfaces via Atomic‐Level Engineering
Advanced Science, EarlyView.The integration of gallium nitride (GaN) with ultrahigh‐thermal‐conductivity boron arsenide (BAs) substrates represents a promising pathway for developing next‐generation high‐power devices. The heat dissipation capability of such integrated systems is fundamentally governed by thermal transport across GaN/BAs interfaces, and buffer layers such as ...

Refined Arithmetic, Geometric and Harmonic Mean Inequalities
Rocky Mountain Journal of Mathematics, 2003 Noting that \(1-1/x\) is a concave function the author applies the Hermite-Hadamard inequality \[ {f(a) + f(b)\over 2}\leq {1\over b-a}\int_a^b f\leq f\bigl((a+b)/2\bigr) \] to obtain the inequalities \[ {(x-1)^2\over2x}\leq(\geq)\, x-1-\log x\leq(\geq)\, {(x-1)^2\over x+1},\quad x>1(\leq 1).

MXene‐Based Room‐Temperature NO2 Gas Sensors: A Meta‐Analysis
Advanced Science, EarlyView.This study presents the first comprehensive meta‐analysis of MXene‐based NO2 sensors, decoding 32 study characteristics across 61 peer‐reviewed studies. By isolating materials chemistry as the primary performance driver over device‐level parameters, the authors establish a methodological blueprint and a predictive structure–function map to accelerate ...

Proposal and validation of geostatistical-based metrics to quantify within-field variability [PDF]
Revista Brasileira de Ciência do SoloMetrics are fundamental to quantify and classify the spatial dependence of soil and agricultural attributes. This study aimed to propose and validate metrics based on two distinct approaches, one additive, which considers the arithmetic mean of the ...
