This paper describes a 1GHz differential to single-ended amplifier for instrumentation. The unity gain amplifier can directly drive a 50Ω load with a common-mode voltage centered at ground and can accept up to a 1 VP-P input signal. The measured noise floor is below 20nV/√Hz for most of the bandwidth and the common-mode rejection is 20dB at 1GHz.

Efficient mass transport through porous networks is essential for achieving rapid response times in sensing applications utilizing porous materials. In this work, we show that open-ended porous membranes can overcome diffusion challenges experienced by closed-ended porous materials in a microfluidic environment. A theoretical model including both transport and reaction kinetics is employed to s...

The  purpose of this  study  is  to  assess  the  practice  and  challenges of BSC  encountered  by  public  higher education institutions   as  a strategic management  tool  in  implementing  their  strategic  plans. In this research, the researchers used  both  quantitative  and  qualitative  research  approaches  in  its  successful  accomplishment.  The  quantitative  frames  will  be  made...

Many real-life large-scale datasets are open-ended and dynamic: new images are continuously added to existing classes, new classes appear over time, and the semantics of existing classes might evolve too. Therefore, we study large-scale image classification methods that can incorporate new classes and training images continuously over time at negligible cost. To this end we consider two distanc...

Ethoxy-, methoxy- and hydroxy-terminated polydimethylsiloxanes (PDMS) are formed as the result of the methanolysis of diethoxy-ended PDMS during its infusion in electrospray ionization. The negative ion mode permits only hydroxy-ended products to be detected, and isomeric interference is avoided in single stage and tandem mass spectrometry. The routes for the fragmentation of (ethyl, hydroxy)-,...

The convergent validity of popularly used open-ended and closed-ended self-report measures of smoking was examined. Carbon monoxide (CO) samples were obtained as an independent method of assessing recent smoking. In addition to CO, 5 known psychosocial correlates of smoking (attitude, subjective norm, risk-taking, best friend's smoking, and other friends' smoking) were used to estimate converge...

Single-ended double-strand breaks (DSBs) are a common form of spontaneous DNA break, generated when the replisome encounters a discontinuity in the DNA template. Given their prevalence, understanding the mechanisms governing the fate(s) of single-ended DSBs is important. We describe the influence of the Ku heterodimer and Mre11 nuclease activity on processing of single-ended DSBs. Separation-of...

LinkedIn is one of the most popular social networking sites that is used for professional purposes and it is the world’s largest professional network as well. The aim of this study is to explore the uses and gratifications of LinkedIn among users in Turkey. For this, a two-stage approach was used. In the first stage, a total of 45 open-ended questionnaires were collected and 33 closed-ended ite...
