Suspension theory for the effect of silt particles on attenuation of compressional waves in marine mud sediments [PDF]
Proceedings of Meetings on Acoustics, 2016 Mud in marine sediments is a mixture of clay and silt particles. Paper follows a suggestion by Holland and Dosso (JASA, 2013) that the variability of the measured frequency-dependent compressional wave attenuation may be caused by the variability of the amounts of silt particles. The premise is that the silt particles are in suspension.

On compactly generated torsion pairs and the classification of co-t-structures for commutative noetherian rings [PDF]
, 2014 We classify compactly generated co-t-structures on the derived category of a commutative noetherian ring. In order to accomplish that, we develop a theory for compactly generated Hom-orthogonal pairs (also known as torsion pairs in the literature) in ...

From m-clusters to m-noncrossing partitions via exceptional sequences [PDF]
, 2011 Let W be a finite crystallographic reflection group. The generalized Catalan number of W coincides both with the number of clusters in the cluster algebra associated to W, and with the number of noncrossing partitions for W.

Silting theory under change of rings
, 2022 The main goal of this paper is to compare the silting theory of an $R$-algebra $Λ$ over a Noetherian ring $R$ with that of its tensor product $Λ\otimes Γ$ with another $R$-algebra $Γ$. In the case that the $R$-algebra $Λ$ is Noetherian, $R$ a complete local ring and $\mathfrak{a}$ a certain ideal of the ring $R$, we obtain an isomorphism between the ...

$\tau$-tilting finiteness of two-point algebras I [PDF]
, 2019 In this paper, we give criteria on $\tau$-tilting finiteness for two kinds of two-point algebras. Moreover, we show the $\tau$-tilting finiteness of some algebras, such as the (infinite-)tame block algebras of Hecke algebras of classical type over an ...

Silting mutation in triangulated categories
, 2011 In representation theory of algebras the notion of `mutation' often plays important roles, and two cases are well known, i.e. `cluster tilting mutation' and `exceptional mutation'.

Silting and cosilting classes in derived categories
, 2017 An important result in tilting theory states that a class of modules over a ring is a tilting class if and only if it is the Ext-orthogonal class to a set of compact modules of bounded projective dimension.

Experimental study and statistical theory of creep behavior of warm frozen silt
KSCE Journal of Civil Engineering, 2016 To investigate the soil parameters and stochastic mechanical characteristics of warm frozen silt, a series of triaxial compression tests were conducted on frozen silt at the temperature of -1.5°C under confining pressures of 0.5, 1.0, and 2.0 MPa. The results indicate that the creep properties of warm frozen silt are affected considerably by stress ...

Classifying tilting complexes over preprojective algebras of Dynkin type
, 2017 We study tilting complexes over preprojective algebras of Dynkin type. We classify all tilting complexes by giving a bijection between tilting complexes and the braid group of the corresponding folded graph.

Global Nitrogen Deposition Promotes Carbon Sink Formation in Terrestrial Ecosystems
Advanced Science, EarlyView.Nitrogen deposition alleviates ecosystem N limitation and enhances carbon sinks. Using 829 observations, we show 36% of deposited N is retained globally (39.15 Tg N yr−1), with distinct NHx and NOy contributions. This retention drives a terrestrial C sink of 0.88 Pg C yr−1 (25.48%), highlighting the importance of pool‐specific C:N stoichiometry ...
