THE EFFECT OF OWNERSHIP STRUCTURE ON THE PRICE EARNINGS RATIO — R... Business Administration

Prior studies document the systematic tendency for firms with low price to earnings ratios (LPE) to earn higher stock returns and firms with high price to earnings ratios (HPE) to earn lower stock returns, in both the United States and in international markets (Campbell & Shiller, 2001; Capaul, Rowl...

THE ATMOSPHERIC CHEMISTRY OF PARTICULATE-BOUND POLYCYCLIC AROMATI... Bio Chemistry

Atmospheric particulate matter with diameter <2.5 um (PM2.5) was collected at Peking University (PKU) in Beijing, China before, during, and after the 2008 Olympics and analyzed for black carbon (BC), organic carbon (OC), lower molecular weight (MW<300) and MW302 Polycyclic Aromatic Hydrocarbons (P...

HETEROAGGREGATION BETWEEN CITRATE-STABILIZED GOLD NANOPARTICLES A... Chemical Engineering

Understanding the aggregation behavior of engineered nanomaterials (ENMs) in aqueous environments is essential to understanding their fate, transport, and toxicity. Because naturally occurring colloids will likely be present at much higher concentrations than ENMs in environmental systems, heteroag... Continue Reading

LEAF PROCESSING BEHAVIOUR IN ATTA LEAFCUTTER ANTS 90% OF LEAF CUT... Bio Chemistry

We observed and videotaped processing behaviours of our laboratory A. cephalotes colony. For ease of recording, we scooped roughly 10 cm diameter balls of comb material and the associated ants into glass-topped containers and provided them with Rubus armeniacus or Prunus lusitanica leaves. During mo... Continue Reading

VALENCE CHANGE ABILITY AND GEOMETRICAL OCCUPATION OF SUBSTITUTION... Chemical Engineering

Nanoparticles were then mixed with Vulcan carbon CX72 with a mass ratio of C:XFe2O4 = 40:60. The as-prepared C/XFe2O4 (XFe2O4 = 60 w%) material and polyvinylidene difluoride (PVDF) were mixed in a mass ratio of 90:10 and dispersed in N-methyl pyrrolidone (NMP). The resulting slurry was pasted onto n... Continue Reading

A MULTIPLEXER-BASED DIGITAL PASSIVE LINEAR COUNTER (PLINCO) Electrical Electronics

A ones adder is an important circuit block that is required in many varying applications. This work proposes a design that largely relies on passive transmission-gate multiplexers. Many variations are suggested that can inherently generate a thermometer coded output or one-hot encoded output. The pr... Continue Reading

PROTEOMICS-DRIVEN ANTIGEN DISCOVERY FOR DEVELOPMENT OF VACCINES A... Pharmacy

Pioneered by Rappuoli and colleagues, reverse vaccinology—which initially included genome and later proteome mining—has proven to be very successful in the discovery of vaccine candidates against many pathogenic bacteria (12– 15). In particular, these methodologies paved the way for the newly develo... Continue Reading

USAGE, COSTS, AND BENEFITS OF CONTINUOUS INTEGRATION IN OPEN-SOUR... Computer Science

Continuous integration (CI) systems automate the compilation, building, and testing of software. Despite CI rising as a big success story in automated software engineering, it has received almost no attention from the research community. For example, how widely is CI used in practice, and what are s... Continue Reading

AROMA POTENTIAL IN EARLY- AND LATE-MATURITY PINOT NOIR GRAPES EVA... Food Science And Technolo...

Grape-derived aromas are of great importance to differentiate wines on the basis of the grape variety1 and quality. Grape-derived volatile compounds as well as their precursors are formed during the ripening stage of the grape.2,3 Their specific profiles mainly depend on the variety although environ...

ON-CHIP NEAR-INFRARED SPECTROSCOPY OF CO₂ USING HIGH RESOLUTION P... Electrical Electronics

Carbon dioxide (CO2) is the most important greenhouse gas and the major product of combustion. Detecting CO2 is critical for many practical applications such as combustion control1 and pollution monitoring.2 Of all existing gas sensor technologies, infrared (IR) absorption is widely used as a simple...

SOLAR THERMOCHEMICAL ENERGY STORAGE THROUGH CARBONATION CYCLES OF... Chemical Engineering

Concentrated solar power (CSP) generation combined with energy storage has the intrinsic advantage of dispatchability, which is the ability to provide energy upon demand, or alternatively, store energy when there is no demand. Despite this advantage, a transformational breakthrough is needed in the... Continue Reading

MULTISCALE EFFECTS OF INTERFACIAL POLYMER CONFINEMENT IN SILICA N... Chemical Engineering

For many natural and synthetic composite materials, enhancing or reinforcing the linear and nonlinear viscoelastic properties of polymer (elastomer) materials is accomplished by inclusion filler particles (e.g. carbon black, silica).1–4 Mechanical properties of elastomer systems can be substantial...

HOMOGENEITY GROUPS OF ENDS OF OPEN 3-MANIFOLDS Mathematics

Each Cantor set C in S3 has for complement an open 3-manifold M3 with end set C. Properties of the embedding of the Cantor set give rise to properties of the corresponding complementary 3-manifold M3. See [Souto and Stover 2013], [Garity and Repovš 2013], and [Garity et al. 2014] for examples of thi... Continue Reading

Sputter deposited amorphous Ge thin films had their nanostructure altered by irradiation with highenergy Arþ ions. The change in the structure resulted in a reduction in medium range order (MRO) characterized using fluctuation electron microscopy. The pulsed laser crystallization kinetics of the as-...
