Review on plasma sprayed oxidation resistant coatings for C/C composites

open access: yesXibei Gongye Daxue Xuebao, 2022
Oxidation sensitivity is a critical obstacle to the rapid development of carbon/carbon(C/C) composites as the thermal structural materials in aerospace applications.

Heterotic Weight Lifting [PDF]

open access: yes, 2009
We describe a method for constructing genuinely asymmetric (2,0) heterotic strings out of N=2 minimal models in the fermionic sector, whereas the bosonic sector is only partly build out of N=2 minimal models.

“Do I look fat?” Self-perceived body weight and labor market outcomes [PDF]

open access: yes, 2018
Research reporting that greater body weight is associated with lower wages and employment, particularly among women, focuses on how employers perceive workers. In contrast, we examine whether workers’ own perceptions of body weight influence labor market

Weight Trimming and Propensity Score Weighting

open access: yesPLoS ONE, 2011
Propensity score weighting is sensitive to model misspecification and outlying weights that can unduly influence results. The authors investigated whether trimming large weights downward can improve the performance of propensity score weighting and whether the benefits of trimming differ by propensity score estimation method. In a simulation study, the

Weighted numbers

open access: yesBehavioral and Brain Sciences, 2021
Abstract Clarke and Beck (C&B) discuss in their sections on congruency and confounds (sects. 3 and 4) literature that has challenged the claim that the approximate number system (ANS) represents numerical content. We argue that the propositions put forward by these studies aren't that far from the indirect model of number perception suggested by

Weight modules over generalized Witt algebras with 1-dimensional weight spaces [PDF]

open access: yes, 2004
In this paper, indecomposable and irreducible weight representations with 1-dimensional weight spaces for simple generalized Witt algebras over any field of characteristic 0 are classified.

Drude weight, Meissner weight, rotational inertia of bosonic superfluids: how are they distinguished? [PDF]

open access: yes, 2014
The Drude weight, the quantity which distinguishes metals from insulators, is proportional to the second derivative of the ground state energy with respect to a flux at zero flux. The same expression also appears in the definition of the Meissner weight,

Effect of powder characteristics on microstructure and properties of 30CrMnSiNi2A steels

open access: yesFenmo yejin jishu, 2022
The 30CrMnSiNi2A steel powders were prepared by water atomization (WA), gas atomization (GA), and plasma rotating electrode process (PREP) in this paper.
