We designed a waveguide SIS mixer based on NbN for the 900-GHz band. The waveguide mixer block with an MgO substrate was designed using Hewlett Packard's High Frequency Structure Simulator (HFSS) and uses a waveguide-to-microstip transition. Simulation by HFSS showed that a source impedance of around 60 12 can be achieved from 786 to 988 GHz by using an MgO substrate about 30 gra thick. The tun...

Needlestick/sharp injuries (NSIs/SIs) are a serious threat to medical/nursing students in hospital internships. Education for preventing NSIs/SIs is important for healthcare workers but is rarely conducted and evaluated among vocational school nursing students. We conducted an educational intervention for such students after their internship rotations before graduation. This program consisted o...

Since a real epidemic process is not necessarily Markovian, the epidemic threshold obtained under the Markovian assumption may be not realistic. To understand general non-Markovian epidemic processes on networks, we study the Weibullian susceptible-infected-susceptible (SIS) process in which the infection process is a renewal process with a Weibull time distribution. We find that, if the infect...

In ALMA Memo 321, Plambeck points out that saturation (gain compression) is likely to be a significant factor limiting the calibration accuracy of ALMA observations. In this memo, saturation by broadband noise and CW signals is analyzed for representative SIS receivers operating at different frequencies. Many SIS mixers in current use are expected to exhibit a significant degree of gain compres...

BACKGROUND Due to numerous complications associated to gastrointestinal augmented cystoplasty, this study aimed to analyze the anatomic repair of the bladder of 10 female dogs using grafts of porcine small intestinal submucosa (SIS) seeded with cultured homologous smooth muscle cells, and compare them with the acellular SIS grafts. RESULTS We assessed the possible side effects and complicatio...

A Safety Instrumented System (SIS) is designed to achieve or maintain a safe state of the process when unacceptable process conditions are detected. An SIS is an Independent Protection Layer that is covered by the performance-based standard ANSI/ISA 84.00.01-2004. The risk reduction allocated to the SIS determines its target safety integrity level (SIL). ANSI/ISA 84.00.01-2004 allows a combinat...

Characterization of a partial-loss-of-function, female-specific lethal mutation has identified an X-linked genetic element (1-34.3; 10B4) that functions as a positive regulator of Sxl, a central gene controlling sex determination in Drosophila melanogaster. The name, sisterless-a, was chosen both to suggest functional similarities that exist between this gene and another positive regulator of S...

Peoples can readily and affordably obtain small indigenous fish species (SIS), with a maximum length of 25 cm, that be found in niches bodies water (such as canals, ponds, wetlands, streams, etc.). SIS contribute valuable significant macro- micronutrients Bangladesh. are excellent suppliers vitamins minerals. The main copper, iodine, iron, selenium, chromium, zinc, which help prevent mineral de...

Exploiting the power of the expectation operator and indicator (or Bernoulli) random variables, we present the exact governing equations for both the SIR and SIS epidemic models on networks. Although SIR and SIS are basic epidemic models, deductions from their exact stochastic equations without making approximations (such as the common mean-field approximation) are scarce. An exact analytic sol...

Since a real epidemic process is not necessarily Markovian, the epidemic threshold obtained under the Markovian assumption may be not realistic. To understand general non-Markovian epidemic processes on networks, we study the Weibullian SIS process in which the infection process is a renewal process with a Weibull time distribution. We find that, if the infection rate exceeds 1/ ln(λ1 + 1), whe...
