A sensitive search for dark energy through chameleon scalar fields using neutron interferometry
(IOP Publishing, 2015-01-22)The physical origin of the dark energy, which is postulated to cause the accelerated expansion rate of the universe, is one of the major open questions of cosmology. A large subset of theories postulate the existence of a ... -
Sensitivity of the Solar Heat Gain Coefficient of Complex Fenestration Systems to the Indoor Convection Coefficient
(International Building Performance Simulation Association, 2016)Accurate estimation of the solar gain of a fenestration system is important in analyzing the energy performance of buildings. Recently, models were developed for complex fenestration systems – glazing systems with attachments ... -
Sensor Array for Volatile Organic Compounds based on Doped Poly (2,5-dimethyl aniline)
(Wiley, 2016-12)A sensor array containing five different sensing materials has been created that is able to distinguish between six different volatile organic compounds (VOCs) at an analyte concentration of 5 ppm. While none of the sensing ... -
Sensor Choice for Minimum Error Variance Estimation
(Institute of Electrical and Electronics Engineers, 2017-06-12)A Kalman filter is optimal in that the variance of the error is minimized by the estimator. It is shown here, in an infinite-dimensional context, that the solution to an operator Riccati equation minimizes the steady-state ... -
Sensory Stimulation Training for BCI System based on Somatosensory Attentional Orientation
(Institute of Electrical and Electronics Engineers, 2018-07-04)In this study, we propose a sensory stimulation training (SST) approach to improve the performance of a brain-computer interface (BCI) based on somatosensory attentional orientation (SAO). In this BCI, subjects imagine the ... -
Separating and probing tautomers of protonated nucleobases using differential mobility spectrometry
(Elsevier, 2017-08-26)The protonated nucleobases (C+H)+, (T+H)+, (U+H)+, (A+H)+, and (G+H)+ are investigated in a combined experimental and computational study using differential mobility spectrometry (DMS), mass spectrometry, and electronic ... -
Separation of nanoparticles by a nano-orifice based DC-dielectrophoresis method in a pressure-driven flow
(Royal Society of Chemistry, 2016-10-07)A novel DC-dielectrophoresis (DEP) method employing a pressure-driven flow for the continuous separation of micro/nano-particles is presented in this paper. To generate the DEP force, a small voltage difference is applied ... -
Serum IgM, MH class IIβ genotype and respiratory burst activity do not differ between rainbow trout families displaying resistance or susceptibility to the coldwater pathogen, Flavobacterium psychrophilum
(Elsevier, 2018-01-20)Flavobacterium psychrophilum, the causative agent of bacterial coldwater disease (BCWD) is a significant threat to global aquaculture. True to its name, BCWD tends to occur at temperatures between 8 and 12°C and presents ... -
Settleable engineered titanium dioxide nanomaterials for the removal of natural organic matter from drinking water
(Elsevier, 2018-02-15)Four linear engineered TiO2 nanomaterials (LENs) were synthesized and evaluated in terms of settlability and their ability to remove natural organic matter (NOM) from river water. The size, surface characteristics, and ... -
Sex differences in solute and water handling in the human kidney: Modeling and functional implications
(Elsevier, 2021-06)The kidneys maintain homeostasis by controlling the amount of water and electrolytes in the blood. That function is accomplished by the nephrons, which transform glomerular filtrate into urine by a transport process mediated ... -
Sex-specific long-term blood pressure regulation: Modeling and analysis
(Elsevier, 2019-01)Hypertension is a global health challenge: it affects one billion people worldwide and is estimated to account for 60% of all cases or types of cardiovascular disease. In part because sex differences in blood pressure ... -
Sexual Behavior, Risk Perception, And Hiv Transmission Can Respond To Hiv Antiviral Drugs And Vaccines Through Multiple Pathways
(Nature Publishing Group, 2015-10-28)There has been growing use of highly active antiretroviral treatment (HAART) for HIV and significant progress in developing prophylactic HIV vaccines. The simplest theories of counterproductive behavioral responses to such ... -
Shale heavy metal isotope records of low environmental O2 between two Archean oxidation events.
(Frontiers Media, 2022-04-26)Evidence of molecular oxygen (O₂) accumulation at Earth’s surface during the Archean (4.0–2.5 billion years ago, or Ga) seems to increase in its abundance and compelling nature toward the end of the eon, during the runup ... -
Shear deformation effects on stability of unbraced steel frames in variable loading
(Journal of Constructional Steel Research, 2019-11-11)The generalized lateral stiffness equation of a semi-rigidly connected frame with accounting for shear deformation is derived in this paper. The lateral stiffness equation can be used to determine the critical loads of ... -
Shear Viscosity of Poly (acrylamide/acrylic acid) Solutions
(Wiley, 2016-02-22)Acrylamide (AAm)/Acrylic acid (AAc) copolymers are being used in a wide spectrum of applications, from which enhanced oil recovery (EOR) is the target application in this research study. The shear viscosity of the copolymer ... -
The Shifted Turan Sieve Method on Tournaments
(Cambridge University Press, 2019)Abstract. We construct a shi ed version of the Turán sieve method developed by R. Murty and the second author and apply it to counting problems on tournaments. More precisely, we obtain upper bounds for the number of ... -
The shifted Turan sieve method on tournaments II
(Elsevier, 2021-12)In a previous work [5], we developed the shifted Turán sieve method on a bipartite graph and applied it to problems on cycles in tournaments. More precisely, we obtained upper bounds for the number of tournaments which ... -
Shipment consolidation with two demand classes: Rationing the dispatch capacity
(Elsevier, 2018-10-01)We analyze the problem faced by a logistics provider that dispatches shipment orders (parcels or larger packages) of two order classes, viz. expedited and regular. Shipment orders arrive according to a compound Poisson ... -
Short Directed Cycles in Bipartite Digraphs
(Springer Nature, 2020-08-01)The Caccetta-Häggkvist conjecture implies that for every integer k ≥ 1, if G is a bipartite digraph, with n vertices in each part, and every vertex has out-degree more than n/(k+1), then G has a directed cycle of length ... -
