Some applications of the sensor network require precise time synchronization among local clocks of the sensors. Due to the limited resource in the sensor network, it is not trivial to maintain the said synchronization. In this paper, we propose a novel method, referred to as the state-based synchronization protocol (SBSP) to solve this issue. We create a finite state machine in the SBSP to desc...
Asteroids with satellites are natural laboratories to constrain the formation and evolution of our solar system. The binary Trojan asteroid (624) Hektor is the only known Trojan asteroid to possess a small satellite. Based on W. M. Keck adaptive optics observations, we found a unique and stable orbital solution, which is uncommon in comparison to the orbits of other large multiple asteroid syst...
The Many Body Localized Phase (MBL) is a phase that exists in distinction to the Ergodic phase. As such, the MBL phase violates the Eigenstate Thermalization Hypothesis and does not undergo thermalization. In this paper, the Ergodic to MBL phase transition will be explored with Artificial Neural Networks (ANNs) trained on a Heisenberg spin chain with disorder. One of the main aspects explored i...
Fluctuations in the basal level of luteinizing hormone (lh) in the plasma of ewes have been measured by the radioimmunoassay technique (Niswender, Roche, Foster & Midgley, 1968; Goding, Catt, Brown, Kaltenbach, Cumming & Mole, 1969). Goding et al. (1969) and Bolt, Kelley & Hawk (1970) reported that the injection ofoestradiol into the ewe caused lh release. In rams, however, the basal level ofpl...
The present paper concerns a numerical benchmark of various turbulence modelings, from RANS to LES, applied to Taylor-Couette-Poiseuille flows in a narrow gap cavity for six different combinations of rotational and axial Reynolds numbers. Two sets of refined Large-Eddy Simulation results, using the WALE and the Dynamic Smagorinsky subgrid scale models available within an in-house code based on ...
An optimization method is introduced for generating minimum-length test sequences taking into account timing constraints for FSM models of communication protocols. Due to active timers in many of today's protocols, the number of consecutive self-loops that can be traversed in a given state before a timeout occurs is limited. A test sequence that does not consider timing constraints will likely ...
This paper presents the architecture and the preliminary evaluation of a request routing DNS server that decouples server selection from the rest of DNS functionality. Our DNS server, which we refer to as MyXDNS, exposes well-defined APIs for uploading an externally computed server selection policy and for interacting with an external network proximity service. With MyXDNS, researchers can expl...
Because the bandwidth usage of broadband wireless access networks is limited, a crucial goal in this field is to improve the system throughput and provisioning of QoS by supporting multiple users based on limited bandwidth resources. This study proposes a two-stage mechanism, called PSBA, to process the operations of packet scheduling and bandwidth allocation based on channel quality informatio...
The relationship between the sperm-coating antigens of rabbit seminal plasma and the phenomenon of decapacitation was studied using agar-gel diffusion, immuno-electrophoresis, chromatography on Sephadex G-200, and polyacrylamide vertical gel electrophoresis. Interpretation of data obtained with these techniques led to the conclusion that a sperm-coating antigen of seminal plasma origin possesse...
LHRH-stimulated LH and FSH secretion was studied in hemipituitaries, in vitro, obtained from several dystrophic mouse mutants (male : 129/ReJ-dy ; 129B6F1/J\x=req-\ dy; C57BL/6J-dy and C57BL/6J-dy2J; female: 129B6F1/J-dy)and a dystrophic hamster mutant (male and female CHF-147). Without exception, pituitary tissue from dystrophic animals released significantly more FSH than did tissue obtained ...
