• #### Physical and real-time delineations on the electro-mechanical threshold ﻿

(1995)
As we increasingly encounter electronic communication and information systems in our everyday environment, we must recognize and critically respond to their impact on built architecture and on our physical and social bodies. ...
• #### Physical attractiveness biases in ratings of employment suitability: In search of the "beauty is beastly" effect ﻿

(2002)
The "beauty is beastly" effect, in which physically attractive females are held at a disadvantage in selection for male sex-typed jobs, is often cited in the physical attractiveness bias research, but has rarely ever been ...
• #### PHYSICAL CHARACTERIZATION AND HYDROISOMERIZATION ACTIVITY OF A PLATINUM-RHENIUM/PILLARED CLAY CATALYST ﻿

(1985)
Montmorillonite is a clay mineral which when exchanged with hydroxyaluminum oligomers produces a pillared clay mineral. On calcination at 500(DEGREES)C the pillars are fixed, and a microporous structure having good thermal ...
• #### Physical characterization of lithium niobate thin films on silicon substrates ﻿

(1988)
The structure and orientation of radio frequency sputtered lithium niobate (LiNbO$\sb3$) films on silicon substrates is determined using x-ray diffraction. The structure of the LiNbO$\sb3$ films is determined to be a strong ...
• #### Physical examination of binding parameters for tryptophan and oligomerization of tryptophan repressor and its site-specific mutants ﻿

(1988)
The interactions of Escherichia coli trp aporepressor and its ligands, tryptophan and trp operator DNA, were examined. To avoid the interference of fluorescence from the ligand, a hydrophobicity-dependent fluorophore, ...
• #### Physical Implementation of Synchronous Duty-Cycling MAC Protocols: Experiences and Evaluation ﻿

(2013-07-24)
Energy consumption and network latency are important issues in wireless sensor networks. The mechanism duty cycling is generally used in wireless sensor networks for avoiding energy consumption due to idle listening. Duty ...

• #### Physical Layer Algorithm and Hardware Verification of MIMO Relays Using Cooperative Partial Detection ﻿

(2010-03-01)
Cooperative communication with multi-antenna relays can significantly increase the reliability and speed. However, cooperative MIMO detection would impose considerable complexity overhead onto the relay if a full ...
• #### Physical layer algorithms with limited feedback: Power control and coding strategies ﻿

(2007)
The uncertainty in the received signal is the main limiting factor for the throughput of any communication system with limited resources. In this thesis we analyze the potential gain in throughput by managing channel ...
• #### PHYSICAL MAPPING OF THE ORIGINS OF REPLICATION OF BACILLUS SUBTILIS BACTERIOPHAGE SP01 ﻿

(1985)
The DNA of Bacillus subtilis bacteriophage SP01 is a linear duplex 140 kilobasepairs long, with direct terminal repeats of 12.4 kilobasepairs. It contains the unusual base 5-hydroxymethyluracil in place of thymine. Southern ...
• #### Physical model of the immune response of bacteria against bacteriophage through the adaptive CRISPR-Cas immune system ﻿

(2013)
Bacteria and archaea have evolved an adaptive, heritable immune system that recognizes and protects against viruses or plasmids. This system, known as the CRISPR-Cas system, allows the host to recognize and incorporate ...
• #### Physical removal of metallic carbon nanotubes from nanotube network devices using a thermal and fluidic process ﻿

(2013)
Electronic and optoelectronic devices based on thin films of carbon nanotubes are currently limited by the presence of metallic nanotubes. Here we present a novel approach based on nanotube alkyl functionalization to ...

(1979-10)

(1921-04)
• #### Physician supply, treatment, and amputation rates for peripheral arterial disease ﻿

(2005)
Objective: To test whether the availability of vascular surgeons and interventional radiologists in a region affects revascularization and amputation rates for patients with peripheral arterial disease (PAD). Methods: We ...
• #### Physicists Gather For Conference Joint Meeting Of Famous Societies ﻿

(1963-03-06)
