The Renal Activity Index for Lupus Identifies Active Renal Disease and Treatment Response in Adult Patients With Systemic Lupus Erythematosus and Lupus Nephritis

Arthritis Care &Research, EarlyView.
Objective We evaluated the ability of the Renal Activity Index for Lupus (RAIL) to discriminate active lupus nephritis (LN) in adult patients with active systemic lupus erythematosus (SLE) and differentiate LN treatment response. Methods Urine samples from adults with biopsy‐proven active class III and IV LN from TULIP‐LN (active LN group ...

Marked Long‐Term Improvement in Lung Function in Melanoma Differentiation–Associated Protein 5 Antibody–Positive Dermatomyositis Patients: Experience of a Single‐Center Longitudinal Cohort in North America

Arthritis Care &Research, EarlyView.
Objective The objective of this study was to describe the longitudinal disease course and pulmonary outcomes of North American patients with melanoma differentiation–associated protein 5 (MDA5) antibody–associated dermatomyositis (DM). Methods Thirty patients with MDA5 antibody–associated DM were identified in a single‐center longitudinal cohort of 352

P-Algebras

Axioms
Following the notions of Ω-set and Ω-algebra where Ω is a complete lattice, we introduce P-algebras, replacing the lattice Ω by a poset P. A P-algebra is a classical algebraic structure in which the usual equality is replaced by a P-valued equivalence ...

Congruences and group congruences on a semigroup [PDF]

Semigroup Forum, 2012
Let \(S\) be a semigroup and \(E\) be the set of idempotents of \(S\). A subsemigroup \(N\) of \(S\) is called normal if it is full (i.e., \(E\subseteq S\)), dense (i.e., \((\forall s\in S)(\exists x,y\in S)(sx,ys\in N)\)), reflexive (i.e., \((\forall a,b\in S)(ab\in N\Rightarrow ba\in N)\)) and closed in \(S\) (i.e., \(N\omega=N\), where \(N\omega=\{s\

Congruences for Fishburn numbers modulo prime powers

, 2014
The Fishburn numbers $\xi (n)$ are defined by the formal power series \[ \sum_{n \geq 0} \xi (n) q^n = \sum_{n \geq 0} \prod_{j = 1}^n (1 - (1 - q)^j). \] Recently, G. Andrews and J.

Cubic congruences.

Michigan Mathematical Journal, 1957
Es wird bewiesen, daß jede Kongruenz \(\sum_{i=1}^n \alpha_ix_i^3\equiv 0 \pmod {\mathfrak m}\), wobei die \(\alpha_i\) ganze Zahlen eines Ringes algebraischer Zahlen sind und \(\mathfrak m\) ein Ideal dieses Ringes ist, für \(n\geq 7\) eine nichttriviale Lösung in ganzen Zahlen dieses Ringes besitzt; ferner, daß dies für ...

Discordance between systemic lupus erythematosus disease activity index domain weights and their association with organ damage accrual

Arthritis Care &Research, Accepted Article.
Objective Studies of damage accrual in patients with systemic lupus erythematosus (SLE) show associations with disease activity measured by the SLE Disease Activity Index 2000 (SLEDAI‐2K), but these associations are imperfect. SLEDAI scores are powerfully influenced by weightings (1‐8) assigned to each domain.

A note on finite lattices with many congruences [PDF]

, 2017
By a twenty year old result of Ralph Freese, an $n$-element lattice $L$ has at most $2^{n-1}$ congruences. We prove that if $L$ has less than $2^{n-1}$ congruences, then it has at most $2^{n-2}$ congruences.

Proofs of Some Conjectures of Chan on Appell-Lerch Sums

, 2018
On page 3 of his lost notebook, Ramanujan defines the Appell-Lerch sum $$\phi(q):=\sum_{n=0}^\infty \dfrac{(-q;q)_{2n}q^{n+1}}{(q;q^2)_{n+1}^2},$$ which is connected to some of his sixth order mock theta functions. Let $\sum_{n=1}^\infty a(n)q^n:=\phi(q)$
