Observing Scattering Mechanisms of Bubbled Freshwater Lake Ice Using Polarimetric RADARSAT2 (CBand) and UWScat (X and KuBands)
(IEEE, 20180501)A winter time series of groundbased (X and Kubands) scatterometer and spaceborne synthetic aperture radar (SAR) (Cband) fully polarimetric observations coincident with in situ snow and ice measurements are used to ... 
Ocular impressiontaking  which material is best?
(Wolters Kluwer, 201901)Objectives: To assess the efficacy and effect on clinical signs of a polyvinylsiloxane (Tresident; Shütz Dental Group GmbH, Germany) compared with an irreversible hydrocolloid (Orthoprint; Zhermack SpA, Badia Polesine, ... 
Of, By, and For the Internet: New Media Studies and Public Scholarship
(Routledge, 2018)This paper proposes we must actively work to craft a new media studies of, by, and for the internet, one that must seek to transform rather than simply disrupt both scholarship and the broader social landscape, or our ... 
OFFDIAGONAL CORNERS OF SUBALGEBRAS OF L(Cn)
(Elsevier, 20201215)Let n ∈ N, and consider Cn equipped with the standard inner product. Let A ⊆ L(Cn) be a unital algebra and P ∈ L(Cn) be an orthogonal projection. The space L := P ⊥Aran P is said to be an offdiagonal corner of A, and L ... 
Offnormal solar optical property measurements using an integrating sphere
(Elsevier, 20120101)Shading devices attached to windows can be used to control solar gain and hence reduce building peak load and annual energy consumption. The performance of a shading device in this regard is strongly dependent on its solar ... 
OffNormal SolarOptical Performance of Pleated Drapery: Simulation versus Measurement
(American Society of Heating, Refrigerating and AirConditioning Engineers, 201601)In recent years, significant advances have been made in modeling fenestration with shading attachments. Most shading devices have great potential for reducing both peak building cooling load and annual energy consumption ... 
Oligomerization and hemolytic properties of the Cterminal domain of pyolysin, a cholesteroldependent cytolysin
(NRC Research Press, 201304)Pyolysin (PLO) belongs to the homologous family of the cholesteroldependent cytolysins (CDCs), which bind to cell membranes containing cholesterol to form oligomeric pores of large size. The CDC monomer structure consists ... 
Oligonucleotidefunctionalized hydrogels as stimuli responsive materials and biosensors
(Royal Society of Chemistry, 20110807)Hydrogels are crosslinked hydrophilic polymers that undergo swelling in water. The gel volume is affected by many environmental parameters including temperature, pH, ionic strength, and solvent composition. Therefore, these ... 
OMG I can IM the QEII: Networking Through chat
(20070522)Presentation slides as presented at the Newfoundland and Labrador Library Association (NLLA) Conference, 2007. Outlines virtual library reference program in the context of the QEII, a chat program offered at Memorial ... 
On a 2class polling model with reneging and ki limited service
(Springer, 20180618)This paper analyzes a 2class, singleserver polling model operating under a kilimited service discipline with classdependent switchover times. Arrivals to each class are assumed to follow a Poisson process with phasetype ... 
On a general mixed priority queue with server discretion
(Taylor & Francis, 20161001)We consider a singleserver queueing system which attends to N priority classes that are classified into two distinct types: (i) urgent: classes which have preemptive resume priority over at least one lower priority class, ... 
On Achieving High Survivability in Virtualized Data Centers
(Institute of Electronics, Information and Communication Engineers, 20140101)As businesses are increasingly relying on the cloud to host their services, cloud providers are striving to offer guaranteed and highlyavailable resources. To achieve this goal, recent proposals have advocated to offer ... 
On Aharoni’s rainbow generalization of the Caccetta–Häggkvist conjecture
(Elsevier, 20210501)For a digraph G and v is an element of V(G), let delta(+)(v) be the number of outneighbors of v in G. The CaccettaHaggkvist conjecture states that for all k >= 1, if G is a digraph with n = V(G) such that delta(+)(v) ... 
On estimands arising from misspecified semiparametric ratebased analysis of recurrent episodic conditions
(Wiley, 20191110)Marginal ratebased analyses are widely used for the analysis of recurrent events in clinical trials. In many areas of application, the events are not instantaneous but rather signal the onset of a symptomatic episode ... 
On Eulerian orientations of evendegree hypercubes
(Elsevier, 20180901)It is well known that every Eulerian orientation of an Eulerian 2kedge connected (undirected) graph is strongly kedge connected. A longstanding goal in the area is to obtain analogous results for other types of connectivity, ... 
On fixed points of self maps of the free ball
(Elsevier, 20180701)In this paper, we study the structure of the fixed point sets of noncommutative self maps of the free ball. We show that for such a map that fixes the origin the fixed point set on every level is the intersection of the ... 
On nonequilibrium shrinkage of supercritical CO2 droplets in a watercarrier microflow
(AIP Publishing, 20180716)We report an experimental study on the hydrodynamic shrinkage of supercritical carbon dioxide (scCO(2)) microdroplets during a nonequilibrium process. After scCO(2 )microdroplets are generated by water shearing upon a ... 
On selfadjoint extensions of semigroups of partial isometries
(American Mathematical Society, 2016)Let S be a semigroup of partial isometries acting on a complex, infinite dimensional, separable Hilbert space. In this paper we seek criteria which will guarantee that the selfadjoint semigroup T generated by S consists ... 
On Specht's Theorem in UHF C⁎algebras
(Elsevier, 20210101)Specht's Theorem states that two matrices A and B in Mn(C) are unitarily equivalent if and only if tr(w(A;A )) = tr(w(B;B )) for all words w(x; y) in two noncommuting variables x and y. In this article we examine to what ... 
On symmetric intersecting families of vectors
(Cambridge University Press, 202111)A family of vectors in [k]n is said to be intersecting if any two of its elements agree on at least one coordinate. We prove, for fixed k ≥ 3, that the size of any intersecting subfamily of [k]n invariant under a transitive ...
