An insidious cardiac sarcoma presenting with progressive neurologic dysfunction.

Rare tumors

Pasalic D, Hegerova LT, Gonsalves WI, Robinson S.
PMID: 24416490
Rare Tumors. 2013 Oct 18;5(4):e56. doi: 10.4081/rt.2013.e56. eCollection 2013.

Central nervous system metastases as the presentation of primary cardiac sarcoma are a very rare entity, with only a few previously reported cases. Sarcomas specifically make up 10 to 20% of all primary cardiac tumors. Patients with primary cardiac...

Aromatic Sulfonium Polyoxomolybdates: Solid-State Photochromic Materials with Tunable Properties.

Chemistry (Weinheim an der Bergstrasse, Germany)

Kumar A, Devi M, Mamidi N, Gonsalves KE, Pradeep CP.
PMID: 26502775
Chemistry. 2015 Dec 14;21(51):18557-62. doi: 10.1002/chem.201503574. Epub 2015 Nov 10.

A new aromatic sulfonium counter-ion motif for polyoxometalate (POM) clusters with potential for structural and electronic fine-tuning has been designed. Its two derivatives 4-hydroxyphenyl dimethylsulfonium triflate (HPDST) and 4-(allyloxy)phenyl dimethylsulfonium triflate (APDST) exhibit ionic liquid behaviors under ambient conditions....

Reactivity of 2-halo-2H-azirines. 1. Reactions with nucleophiles.

The Journal of organic chemistry

Pinho e Melo TM, Lopes CS, Gonsalves AM, Beja AM, Paixão JA, Silva MR, da Veiga LA.
PMID: 11777440
J Org Chem. 2002 Jan 11;67(1):66-71. doi: 10.1021/jo010504v.

Nucleophilic substitution reactions of 2-halo-2H-azirines 1a, 1b, 1d, and 1e with potassium phthalimide and aniline allowed the preparation of new substituted 2H-azirines 2-5. The reactions of 2-bromo-2H-azirine 1a with methylamine led to the synthesis of alpha-diimines 7 and 8....

Transverse interferometry of a hydrogen-filled capillary discharge waveguide.

Physical review letters

Gonsalves AJ, Rowlands-Rees TP, Broks BH, van der Mullen JJ, Hooker SM.
PMID: 17358614
Phys Rev Lett. 2007 Jan 12;98(2):025002. doi: 10.1103/PhysRevLett.98.025002. Epub 2007 Jan 09.

Transverse interferometric measurements are presented of the plasma channel formed in a hydrogen-filled capillary discharge waveguide recently used to generate 1 GeV electrons in a laser-driven plasma accelerator for the first time. The measurements were found to be in...

Cramér-Rao bounds on mensuration errors.

Applied optics

Gonsalves RA.
PMID: 20165164
Appl Opt. 1976 May 01;15(5):1270-5. doi: 10.1364/AO.15.001270.

The Cramér-Rao (CR) bound is an inequality that sets a lower bound on the variance of an estimator. The paper presents an application of this bound to the problem of mensuration. Explicit results are given for the width of...

Nonisoplanatic imaging by phase diversity.

Optics letters

Gonsalves RA.
PMID: 19844351
Opt Lett. 1994 Apr 01;19(7):493-5. doi: 10.1364/ol.19.000493.

Phase diversity allows one to use multiple images with known phase changes such as defocus to learn the optical characteristics of an imaging medium and to estimate the unknown object. It is shown that the method can be extended...

Small-phase solution to the phase-retrieval problem.

Optics letters

Gonsalves RA.
PMID: 18040419
Opt Lett. 2001 May 15;26(10):684-5. doi: 10.1364/ol.26.000684.

A solution to the phase-retrieval problem when the unknown phase is small is presented. The solution specifies the even and odd parts of the unknown phase in two separate equations. The odd part requires a single intensity measurement, and...

W production at large transverse momentum at the CERN Large Hadron Collider.

Physical review letters

Gonsalves RJ, Kidonakis N, Sabio Vera A.
PMID: 16384211
Phys Rev Lett. 2005 Nov 25;95(22):222001. doi: 10.1103/PhysRevLett.95.222001. Epub 2005 Nov 21.

We study the production of W bosons at large transverse momentum in pp collisions at the CERN Large Hadron Collider. We calculate the complete next-to-leading order (NLO) corrections to the differential cross section. We find that the NLO corrections...

Secondary Hemophagocytic Syndrome Associated with Richter's Transformation in Chronic Lymphocytic Leukemia.

Case reports in hematology

El-Haj N, Gonsalves WI, Gupta V, Smeltzer JP, Parikh SA, Singh PP, Gangat N.
PMID: 24551464

Hemophagocytic syndrome (HPS) is an extremely rare condition arising from the overactivation of one's own immune system. It results in excessive inflammation and tissue destruction. Prompt initiation of treatment is warranted in either scenario in order to decrease mortality....
