Inverse melting and inverse freezing: A spin model [PDF]
Physical Review E, 2005 Systems of highly degenerate ordered or frozen state may exhibit inverse melting (reversible crystallization upon heating) or inverse freezing (reversible glass transition upon heating). This phenomena is reviewed, and a list of experimental demonstrations and theoretical models is presented.

Squared distance matrices of trees with matrix weights
AKCE International Journal of Graphs and Combinatorics, 2023 Let T be a tree on n vertices whose edge weights are positive definite matrices of order s. The squared distance matrix of T, denoted by Δ, is the ns × ns block matrix with [Formula: see text], where d(i, j) is the sum of the weights of the edges in the ...

Optimal Regularized Inverse Matrices for Inverse Problems [PDF]
SIAM Journal on Matrix Analysis and Applications, 2017 In this paper, we consider optimal low-rank regularized inverse matrix approximations and their applications to inverse problems. We give an explicit solution to a generalized rank-constrained regularized inverse approximation problem, where the key novelties are that we allow for updates to existing approximations and we allow for incorporation of ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Cytomegalovirus (CMV) is a recognized trigger of immune thrombocytopenia (ITP); however, its incidence and impact on disease course in children remain controversial. Therefore, we aimed to characterize the clinical course of pediatric patients with CMV‐associated ITP.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Outcomes in relapsed or refractory pediatric and AYA bone sarcomas remain poor, and the impact of early referral to specialized sarcoma centers on survival is unclear. Early centralization of care may improve local and systemic treatment quality, but evidence in this population is limited.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Inverse problems for elliptic equations with fractional power type nonlinearities
, 2022 We study inverse problems for semilinear elliptic equations with fractional power type nonlinearities. Our arguments are based on the higher order linearization method, which helps us to solve inverse problems for certain nonlinear equations in cases ...

Direct and inverse scattering from dispersive media [PDF]
, 1994 Direct and inverse scattering from dispersive media are studied in the time domain. The media are one-dimensional and homogeneous but can be impedance mismatched to the surrounding media.

Inverse Problems Have Inverse Complexity [PDF]
, 2008 In this paper we show that inverting problems of higher complexity is easier than inverting problems of lower complexity. While inverting Σp i3CNFSAT is known to be coNP-complete sideri for i=1 we prove that it remains coNP-complete for i=2 and is in P for all i⩾ 3. Relatedly, we show that inverting Σp i3DNFSAT is in P for all i⩾ 1.
