Biomass proximate analysis using thermogravimetry

Bioresource Technology, 2013
This work proposes a 25 min-last thermogravimetric method as a tool to determine biomass sample's proximate analysis data (moisture, ash, volatile matter and fixed carbon contents) just by direct measure of weight changes on each sample's TG chart. Compared with international standards commonly used to that aim, TG is a faster and easier to develop ...

Proximal mediation analysis

Biometrika, 2023
Summary A common concern when trying to draw causal inferences from observational data is that the measured covariates are insufficiently rich to account for all sources of confounding. In practice, many of the covariates may only be proxies of the latent confounding mechanism.

Proximate Analysis of Biomass

International Journal of Membrane Science and Technology, 2023
One of the sustainable and renewable energy sources that doesn't produce a lot of greenhouse gas emissions is biomass. Using biomass energy effectively will aid in addressing issues brought on by the use of fossil fuels. The biomass has only issue of low calorific value. For biomass as a fuel the calorific value plays a very crucial role.

Link Proximity Analysis - Clustering Websites by Examining Link Proximity [PDF]

, 2010
This research-in-progress paper presents a new approach called Link Proximity Analysis (LPA) for identifying related web pages based on link analysis. In contrast to current techniques, which ignore intra-page link analysis, the one put forth here examines the relative positioning of links to each other within websites.

Proximal Analysis and Minimization Principles

Journal of Mathematical Analysis and Applications, 1995
Let \(X\) be a Hilbert space, and suppose \(f:X\to\mathbb{R}\cup\{+\infty\}\) is lower semicontinuous. Given a point \(x\) where \(f(x)0\) and a neighbourhood \(\Omega\) of \(x\) such that \[ f(y)-\langle z y-x\rangle+\sigma|y-x|^2\geq f(x)\quad\forall y\in\Omega.

Cortical thickness analysis of the proximal humerus [PDF]

Shoulder & Elbow, 2017
Background Structural changes within the proximal humerus influence the mechanical properties of the entire bone and predispose to low-energy fractures with complex patterns. The aim of the present study was to measure the cortical thickness in different regions of the proximal humerus.

Magnetic Control of Chiral Hybridized Phonon Magnetic Moments in Ferrimagnets Fe2‐xZnxMo3O8

Advanced Functional Materials, EarlyView.
Helicity‐resolved magneto‐Raman spectroscopy reveals magnetic control of chiral phonon magnetic moments in polar ferrimagnet (ZnxFe2−xMo3O₈). Large spontaneous zero‐field phonon splittings, selective phonon–magnon coupling, and asymmetric Zeeman responses demonstrate that phonon chirality is governed by magnon‐phonon coupling and magnetization.

Variational analysis of proximal compositions and integral proximal mixtures

Evolution Equations and Control Theory
This paper establishes various variational properties of parametrized versions of two convexity-preserving constructs that were recently introduced in the literature: the proximal composition of a function and a linear operator, and the integral proximal mixture of arbitrary families of functions and linear operators.

Steering Oxygen Activation Pathways via Redox Dual‐Defects in 2D Hydrated WO3 for High‐Yield Singlet Oxygen Evolution

Advanced Functional Materials, EarlyView.
Redox dual‐defects (Cs substitution and O vacancies) in 2D hydrated WO3 steer O2 activation toward selective singlet oxygen evolution. WO‐CO achieves 8.6–15.8 times higher 1O2 production than single‐defect or pristine catalysts, enabling efficient pollutant mineralization via a pathway‐selective photocatalytic mechanism.

Evidence for Itinerant Ferromagnetic Flat Bands Producing Large Transverse Responses

Advanced Materials, EarlyView.
Itinerant ferromagnetic flat bands are demonstrated in GdCo5 with a high Curie temperature of 940K, a stacked honeycomb–kagome lattice, through angle‐resolved photoemission spectroscopy and magneto‐thermoelectric measurements. These topological flat bands generate large Berry curvaturte, producing gigantic anomalous Nernst effect with record‐high ...
