θm. 4. Simulation Results In this simulation we assume M HAPs uniformly located along a circular boundary, with the centre of the circular boundary acting as the pointing direction of the HAPs base station antennas which simulate several overlapping cells, see figure 1. The beamwidth of these base station antennas are determined by the radius of the cell coverage area (see figures 1 and 3). These results are acquired through running Monte Carlo simulations of the multiple HAP system. The aim of the simulation is to assess the effect of adding more HAPs on the system’s capacity and of the impact of using space-time diversity techniques. The distance dm between the cell centre and the vertical projection of the HAP on the earth’s surface is denoted as ”distance on the ground” and is varied from 0 to 70 km with a fixed cell position, as shown in figure 4. The distance to the cell centre is also changing the elevation angle θm towards the HAP base station m as seen from the user. The cell radius has been set to 10 km and 30 km, and the HAP altitude is 20 km. Each HAP base station serves 100 users within each corresponding cell.

In a cathode-ray tube (CRT), the movement of the electron beam tracing the image on the screen from the end of the trace to the beginning where it starts over on the next line. Flyback is usu- ally associated with a blanking interval in which the beam is turned off so as not to interfere with the im- age already displayed. There is more than one type of flyback on a monitor. The flyback associated with scanning each line is similar to the line feed and car- riage return on a typewriter, in that the scan finishes at the end of one line and flies back to the next line down (or two lines down in interlaced screens) and the beginning of the subsequent line, in a zigzag (sawtooth) pattern. The other type offlyback is when the full video frame is finished, the beam is at the bottom or last line of the screen and then flies back to the top or first line of the screen. (This example assumes a typical CRT in which the scanning is left to right and top to bottom.)

PTV CT . The largest increase was observed with the heart V30. Although the absolute increase in normal tissue dose seems to be relatively small, clinical consequences can never be ruled out and attempts should always be made to minimise the dose delivered to organs at risk. A number of studies pointed out that patients who received partial irradiation of the heart had an increased risk of dying from cardiac disease [20-22]. In these studies, conven- tional radiotherapy techniques were used. The present study demonstrates that the introduction of CT-guided target definition and planning may result in an increase of the dose delivered to the heart in some cases. Other authors already reported on restricting the 3D-CRT field edges in the vicinity of the heart and the application of cardiac shielding to reduce the heart dose [23]. We also tested this method at our institute in three patients that had upper-quadrant tumour sites. It appeared that the heart V30 could be reduced to 0% at the cost of reduced coverage of the breast PTV CT (Table 4). Although the use of cardiac shielding was not specifically analysed as a part of the current study, it could be regarded as a first and rather safe step towards partial breast irradiation in selected patients who have early-stage disease at locations remote from the heart. In this way, it may be possible to reduce the heart dose with 3D-CRT even below the levels resulting from conventional treatment. A large rand- omized trial would be necessary to determine tumour control probability and normal tissue complication prob- ability with the different uses of 3D-conformal techniques in breast conserving radiotherapy.

topology control in WSNs, we studied coverage provision based on a prior proof that if the radio range of sensor is equal to or greater than twice the sensing range, then complete cov- erage implies connectivity, as a result, the network connectivity is provided as well. Second, algorithm efficiency is another essential aspect of our proposed algorithm. Due to the fact that inefficient ones always produce long time delay and energy dissipation, this problem was thereby investigated by avoiding deadlock during cluster forming phase. Accordingly, we designed a dynamic refusal scheme to break circular-waiting by setting a time-varying possibility in each cluster, which determines whether a merging request should be accepted. The last but not least important, we obtained an energy-balanced network by allowing more than one node in each cluster to keep in an active state. Simulations were conducted to evaluate the performance of our proposed algorithm. The results illustrate that CDSWS outperforms existing algorithms with respect to coverage guarantee, algorithm efficiency and energy conservation.

If the ZIP code prediction is off the mark, it does not necessarily mean a poor sample size. When I consistently received much lower than expected results in the Groton/New London area, I reported this fact to ARDIS. The Motorola maintenance force reported the base station on spec. The coverage results remained dismal. ARDIS network management people were dispatched and found that a new building had been erected beside the base station. It was on spec all right, but blasting much of its energy into a brick wall. An exculpatory comment: Groton/New London has fallen on terrible economic times with the cancellation of virtually all submarine contracts. Message traffic has declined precipitously as users moved away. The practical existence of the problem had thus been somewhat masked.

FUNDAMENTALS OF ACOUSTICS

FUNDAMENTALS OF ACOUSTICS

This effect is due to the thermal conduction: when the pressure increases, the temperature in the elementary volume considered increases as well (Lechatelier’s law, equation (1.22)), but the outward heat transfer from this volume occurs with delay. The average temperature (and consequently the product PV) is then greater in the first curve than in the 2 nd curve: the energy provided to the volume during the compression phase is not released entirely during the decompression. This delay in “going back” to equilibrium is called a relaxation phenomenon. (The phenomena related to viscosity can also be interpreted as relaxation phenomena with delays in impulse transfers.) There are other relaxation phenomena occurring during propagation that are related to physical and chemical equilibrium. One is particularly important since it is responsible for most of the acoustic dissipation in specific conditions in air: the molecular thermal relaxation. It is presented in the forthcoming section.

The rational selection of triple-drug regimens is based pri- marily on the results of clinical trials, but also on the potency and durability of response, drug toxicity, drug- drug interactions, potential for resistant mutation selec- tion, impact on future treatment, and dosing convenience of the individual agents.[2] Although indirect compari- sons of controlled trials of PI- vs NNRTI-based HAART had been made,[36] until the final results of ACTG study 384 were published in December 2003, the clinical effec- tiveness of PI- and NNRTI-based 3-drug combinations had not been compared directly in randomized controlled studies. Because zidovudine/lamivudine and stavudine/ didanosine had been compared previously in clinical tri- als of 2-drug regimens and because of the favorable results observed in these trials,[37,38] these NRTI combinations have been frequently used in 3-drug regimens. NRTIs such as zidovudine, which was introduced almost 2 decades ago, continue to remain reliably effective when used in current combination regimens when patients are adher- ent.

pools, indicating potential rare variants. Tailcurve analysis Initial validations by Sanger sequencing indicated that ~25% or more of these variant calls were false positive. Sequencing errors contribute to false positive calls and are particularly problematic for pooled samples where rare variant frequencies approach the error rate. To determine the effect of cycle-dependent errors on variant calls [7], we analyzed the proportions of each nucleotide called at each of the 47 sequencing cycles in each variant. We refer to this analysis as a tailcurve analysis due to the characteristic profile of these proportion curves in many false-positive variant calls (Figure 5; Additional File 2). This analysis indicated that many false positive calls arise from cycle- dependent errors during later sequencing cycles (Figure 5, Panel D). The default base- calling algorithm (BUSTARD) and the quality values it generates make existing variant detection software prone to false positive calls because of these technical biases. Examples of tailcurves reflecting base composition by cycle at specific genetic loci for wild type, common SNP, rare variant, and false positive calls are shown in Figure 5.

occurs. All these observations are contrary to the conventional quantum-confined nanostructures. These can be attributed to the continuous PL wavelength blue-shift observed in both as-grown and intermixed samples, as shown in Fig. 5, with increasing optical excitation densities. The continuous blue-shift of the PL peak wavelength up to 88 nm in the as-grown sample and 61 nm in the intermixed sample at the optical excitation density of 1500 W/cm 2 , relative to those obtained at the excitation of 3 W/cm 2 , are shown in the inset of Fig. 5. The effect of band-filling is insufficient to explain the large degree of blue- shift observed from sample excited under high density excitation. Hence, it is reasonably ascribed this to the postulation of continuum states (Van der Poel et al., 2006) in the Qdash nanostructures, although spectral widening at a shorter wavelength is expected in an inhomogeneous Qdash structure (Hadass et al., 2004). Continuum states serve as an effective medium for exciton scattering and thus change the dephasing rate (Tan et al., 2007) at each energy level within the highly inhomogeneous ensembles and the radiative recombination profile will be different from that of conventional QW. The wide distribution of energy levels due to the nature of Qdash inhomogeneous (FWHM of 76 nm from PL measurement of as-grown sample at low excitation of 3 W/cm 2 ) will further serve as the radiative recombination states or “sink” for the scattered excitons from the dense continuum states. Consequently, quasi-supercontinuum lasing spectra of the diode laser fabricated from these samples are observed, which will be discussed in the later section. Nevertheless, smaller blue-shift of PL peak wavelength in the intermixed sample, as depicted in the inset of Fig. 5, indicates that IFVD enhances the Qdash inhomogeneity more so in larger sizes of Qdashes, which emit at longer wavelengths. Assuming a uniform injection of group-III vacancies from the surface during the IFVD process, the interdiffusion in the vertical direction will affect the dash height more than other directions (Djie et al., 2008; Wei et al., 2005). At an intermediate stage of intermixing, the thick dash family, where the quantized energy level located closer to the conduction band minima, will experience a larger degree of intermixing as the effective height or thickness of the dash decreases, as depicted in the inset of Fig. 3. In addition, the local effective concentration for the thick dash family is higher than the thin dashes. Under uniform annealing temperature, the thick Qdash family that has larger interdiffusion length will yield larger degree of intermixing. As a result, largest degree of wavelength blue-shift (~65 nm) is observed at low excitation of 3 W/cm 2

3.2 Simulation model of group-III interdiffusion The understanding of diffusion processes is important to the interpretation of interdiffusion induced compositional change and the band structure modification related to the experimental works and selected postgrowth operating conditions presented in the previous sections. In IFVD process, majority vacancies are injected vertically from the dielectric cap during thermal treatment and therefore the interdiffusion will occur more effectively in the transverse direction that corresponds to the dash height (Tan et al., 2008; Wei & Chan, 2005). This diffusion effect becomes more pronounced at very thin Qdash layer when the dash height to base ratio is of ~ 0.1 or less (Wang et al., 2006). At intermediate stage of intermixing, the partial intermixing might occur, which the thick dash family will experience a larger degree of wavelength blue-shift due to the larger concentration (Crank, 1975) of active medium composition and hence its interdiffusion length is larger than the thin dash family. The solution of the diffusion problem (Crank, 1975) in the Qdash can be estimated by an equivalent one dimensional quantum-confined model (transverse direction of vacancies interdiffusion) by assuming a substance of concentration C 0 , confined in a region of n repeating well and barrier of width w and b , respectively, centered at zero (Gontijo et al., 1994) that is given by

Caution should be exercised not to discharge a lithium-based battery too low. Discharging a lithium-based battery below 2.5V may cut off the battery’s protection circuit. Not all chargers accommodate a recharge on batteries that have gone to sleep because of low voltage. Some Li-ion batteries feature an ultra-low voltage cut-off that permanently disconnects the pack if a cell dips below 1.5V. This precaution prohibits recharge if a battery has dwelled in an illegal voltage state. A very deep discharge may cause the formation of copper shunt, which can lead to a partial or total electrical short. The same occurs if the cell is driven into negative polarity and is kept in that state for a while. A fully discharged battery should be charged at 0.1C. Charging a battery with a copper shunt at the 1C rate would cause excessive heat. Such a battery should be removed from service.

BÁO CÁO HÓA HỌC: " RESEARCH ARTICLE SCALABLE COVERAGE MAINTENANCE FOR DENSE WIRELESS SENSOR NETWORKS" DOC

Owing to numerous potential applications, wireless sensor networks have been attracting significant research effort recently. The critical challenge that wireless sensor networks often face is to sustain long-term operation on limited battery energy. Coverage maintenance schemes can effectively prolong network lifetime by selecting and employing a subset of sensors in the network to provide sufficient sensing coverage over a target region. We envision future wireless sensor networks composed of a vast number of miniaturized sensors in exceedingly high density. Therefore, the key issue of coverage maintenance for future sensor networks is the scalability to sensor deployment density. In this paper, we propose a novel coverage maintenance scheme, scalable coverage maintenance (SCOM), which is scalable to sensor deployment density in terms of communication overhead (i.e., number of trans- mitted and received beacons) and computational complexity (i.e., time and space complexity). In addition, SCOM achieves high energy efficiency and load balancing over different sensors. We have validated our claims through both analysis and simulations. Copyright © 2007 Jun Lu et al.

Providing statistics on the multi-path components for the delay profile management is the job of the traffic searcher. Access searcher : after having successfully completed the downlink synchronization, a mobile station enters the cell network by sending a request on a common uplink access channel according to certain schemes. There are several types of access channels but they all have the same global structure: a preamble made of a non-modulated pilot, followed by an encapsulated message. The access searcher’s function is to detect this new user in the cell by monitoring these access channels. Thus, a relatively large search window, proportional to the cell radius, is used. The access searcher searches for the preamble, whose structure differs from one standard to another. The IS-2000 access channel preamble is a simple non-data- bearing PN-spread pilot, while in 3GPP, a 16-chip Walsh signature randomly selected by the mobile station is superimposed on the PN-spread pilot.

Despite minor modifications of the BARRIERS scale across studies, our results support the reliability of the BARRIERS scale; that is, the reported Cronbach's alpha values indicate internal consistency. However, the validity of the scale to accurately capture barriers to research use is much more at issue. This instrument, developed in accordance with healthcare environments in the late 1980s and early 1990s, has been administered predomi- nantly in its original format since then, without detecting any changes in the perceptions of barriers over time. Both healthcare systems and the nursing profession have undergone significant changes over the past 30 years, and it is difficult to believe that such changes have not affected nurses' reported perceptions of barriers to research use. For example, in healthcare today, patient participation in decision making is much more evident and, in some countries, even legally regulated. Patients' preferences and opinions could, hypothetically, present a barrier to research use. Barriers with respect to patients' opinions were added to the BARRIERS scale by Greene, who measured barriers toward pain management in oncology care [51]. 'Patients will not take medication or follow the recommendations' was rated as the third high- est ranked barriers by the nurses.

The piriform aperture is dissected, sometimes removing a portion of the nasal spine, and the nasal mucoperiosteum is dissected back to the hard palate- soft palate junction. The septum either can be sepa- rated bluntly from the vomer or a guarded osteotome can be used. The osteotomy is performed largely with the reciprocating saw, starting laterally in the thick bone beneath the buttress of the zygoma and proceed- ing medially through thinner bone (Fig. 23C.6a,b). The osteotomy through the piriform aperture and medial wall of the antrum is done with the saw blade pointed laterally (Fig. 23C.6 b, c). Section of the pala- tine bone, the sole attachment of the maxillary tuberosity to the pterygoid plate of the sphenoid, is done with either a curved Dautrey osteotome or the somewhat larger Kawamoto osteotome (Fig. 23C.6d). The lateral osteotomy can be taken a bit further back by a few taps on a straight osteotome, and the medial antral wall can be further sectioned with a guarded nasal osteotome. At this point, the only remaining attachment of the lower maxillary segment is the pos- terior wall of the antrum, and firm, downward finger pressure on the maxilla is usually enough to produce a down-fracture (Fig. 23C.6e). If not, the Rowe forceps can be inserted underneath the nasal mucosa and the maxilla completely mobilized with a downward and side-to-side motion. It can be further mobilized with a blunt elevator used as a lever (Fig. 23C.6f,g).
