Oral History Interview: Arno T. Lenz (0366)
No full textIn his 1983 interview with Barry Teicher, Arno T. Lenz discussed his experiences as a student and employee of the University of Wisconsin-Madison from 1924-1974. Lenz cited his courses and faculty during his studies that inspired a career in civil engineering from his undergraduate through his graduate program (1924-1932). The creation and evolution of the civil engineering department, as well as Lenz?s contributions in departmental committees is discussed. Also, Mrs. Lenz spoke on the social obligations of a spouse of a faculty member. This interview was conducted for inclusion into the UW?Madison Oral History Program.

On the theorems of Drake and Lenz
No full textA generalization and an improvement of the results of Drake and Lenz on the constructions of projective Hjelmslev planes are obtained. Using this, some new series of invariant pairs including 4 new pairs (t, 2), t ≤ 1000, for projective Hjelmslev planes are obtained

Algebra of Dunkl Laplace–Runge–Lenz vector
No full textWe introduce the Dunkl version of the Laplace–Runge–Lenz vector associated with a finite Coxeter group W acting geometrically in RN and with a multiplicity function g. This vector generalizes the usual Laplace–Runge–Lenz vector and its components commute with the Dunkl–Coulomb Hamiltonian given as the Dunkl Laplacian with an additional Coulomb potential γ/r. We study the resulting symmetry algebra Rg, γ(W) and show that it has the Poincaré–Birkhoff–Witt property. In the absence of a Coulomb potential, this symmetry algebra Rg, 0(W) is a subalgebra of the rational Cherednik algebra Hg(W). We show that a central quotient of the algebra Rg, γ(W) is a quadratic algebra isomorphic to a central quotient of the corresponding Dunkl angular momenta algebra Hgso(N+1)(W). This gives an interpretation of the algebra Hgso(N+1)(W) as the hidden symmetry algebra of the Dunkl–Coulomb problem in RN. By specialising Rg, γ(W) to g=0, we recover a quotient of the universal enveloping algebra U(so(N+1)) as the hidden symmetry algebra of the Coulomb problem in RN. We also apply the Dunkl Laplace–Runge–Lenz vector to establish the maximal superintegrability of the generalised Calogero–Moser systems
Some projective planes of Lenz-Barlotti class I
No full textWe construct an infinite projective plane with Lenz-Barlotti class I. Moreover, the plane is almost strongly minimal in a very strong sense: each automorphism of each line extends uniquely to an automorphism of the plane.</p
Some new invariant pairs (t,3) for projective Hjelmslev planes
No full textAssociated with every finite projective Hjelmslev plane is an invariant pair (t, r): t is the number of neighbours of a given point on a given line passing through it and r is the order of the underlying projective plane. The Drake-Lenz method [2], [3] of using auxiliary matrices for the constructions of projective Hjelmslev planes has become standard by now. This paper is intended to give some new constructions of projective Hjelmslev planes with invariant pairs (t, 3) by making use of the generalization and improvement of the Drake-Lenz theorem [3] obtained by the author in [6] and [7]. The results of this paper add 8 new values to the list ([5], example 3.7(ii)) of invariant pairs (t, 3) with t ≤ 1,000 for projective Hjelmslev planes
CAR-T Cell Therapy Shows Similar Efficacy and Toxicity in Patients With DLBCL Regardless of CNS Involvement.
No full textEfficacy and toxicity of chimeric antigen receptor T (CAR-T) cell therapy in relapsed/refractory (r/r) diffuse large B-cell lymphoma (DLBCL) with central nervous system (CNS) involvement remain understudied. Here we analyzed the outcomes of CAR-T cell therapy in r/r DLBCL patients with CNS involvement and compared them with patients without CNS disease. Retrospective and monocentric comparative analysis of patient cohort with r/r DLBCL treated with CAR-T cell therapy: 15 patients with CNS versus 65 patients without CNS involvement. Overall response rates (80% versus 80%; P = 1.0), progression-free survival (P = 0.157), and overall survival (P = 0.393) were comparable for both cohorts. The frequency of cytokine release syndrome was comparable in the CNS and non-CNS cohorts; 93% versus 80%; P = 1.0. Numerically, immune effector-cell-associated neurotoxicity syndrome (all grades) was more frequent in patients with CNS manifestation (53% versus 29%; P = 0.063), although no grade 4 events were documented. Our study suggests that CAR-T cell therapy is effective and feasible in patients with r/r DLBCL and CNS manifestation
