Sensitivity of Left Handed Material Film-Superconductor Waveguide Sensors

The sensitivity of planar waveguide sensor containing dielectric, superconductor, and left-handed materials has been theoretically investigated. The proposed waveguide sensor in this study consists of a metamaterial film bounded by a dielectric cover and a superconductor substrate. The variation of the sensor sensitivity are found to be strongly depended on the metamaterial film, the film thickness and the temperature of the superconductor

Non-linear surface waves at a single interface of semimagnetic semiconductor–left handed materials (LHM)

The nonlinear characteristics of TE surface waves at microwave frequencies in a layered structure of non-linear semimagneticsemiconductor cover and left-handed material substrate have been investigated. Numerical analysis and derivation were carried out for the dispersion relation in its general form. The power flow has also been studied as a function of wave number for different frequencies and magnetic fields. It is shown that the proposed waveguide structure depends significantly on the operating wave frequency and can be efficiently controlled by varying the frequency

Distributed Space Time Block Coding for Asynchronous Cooperative Communication Systems

Multiple-Input-Multiple-Output (MIMO) communication techniques have been an important area of focus for 4th generation wireless systems. This is mainly because of their potentials for high capacity, increased diversity, and interference suppression. The cooperative communication techniques can avoid the difficulties of implementing actual antenna arrays and convert the single-input single-output (SISO) system into a virtual MIMO system. In this scheme, the user explores its other neighbor users to act as relaying nodes and forming virtual MIMO system. Space-Time Block Coding (STBC) is used to improve the transmission reliably and spectral efficiency of MIMO systems. When STBC is applied to a cooperative diversity, the system termed as Distributed Space Time Block Code (D-STBC). Most of the existing research assumes perfect synchronization among cooperative users in D-STBC. This means that they have identical timing, carrier frequency, and propagation delay, which is almost impossible to be achieved. The lack of common timing reference can badly influence the performance of the D-STBC system. There are different research efforts to overcome this problem; most of which have high decoding complexity. In this research, two low decoding complexity detection schemes of D-STBC have been proposed and they have proven their efficiency in mitigation the impact of imperfect synchronization between the relay nodes. The first one is based on Parallel Interference Cancellation (PIC) method and the other is based on Successive Interference Cancellation (SIC) method

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

A Move Analysis of a ChatGPT-4o-Generated News Release: Insights from a Quasi-Experimental Study in the Digital Transformation Era

This quasi-experimental paper aims to assess the quality of news releases generated by ChatGPT-4o. To that end, I purposively selected a short news release from PR Newswire—a global press release distribution partner. The news release was divided into sentences and fed to ChatGPT-4o, which was prompted to generate a news release based on the provided information. To orient analysis, the study proposed a rhetorical move model comprising three main constant (obligatory) moves—headline, lead, and body—and optional sub-moves within the lead and body that may vary from one situation to another. This paper recommends customized news release training for ChatGPT. The paper is expected to be of considerable value and benefit to PR educators and practitioners, presenting both (a) a cover-all prompt model for producing news releases using ChatGPT and (b) a model example for manually crafting news releases. Ultimately, the paper lays the groundwork for future research on the capabilities of other AI writing tools and their applications to various genres

The Actualities of Public Relations Practice at an Eastern Ontario University: A Quasi-ethnographic Study

Although various studies have used ethnographic techniques to examine different concepts, contexts, and practices in public relations (Sriramesh, 2000; Daymon & Hodges, 2009), none of these studies ethnographically examined the culture within which public relations is practiced, and discourse is produced in a college or university context. This quasi-ethnographic study aims to: (1) produce an account of the core aspects of the culture within which public relations is practiced at a university in Eastern Ontario and (2) identify what PR model best represents the PR practice there. To collect data for this study, I conducted e-mail interviews with five public relations participants at the university under investigation to collect data for this study. The data collected was about the groups’ routines, practices, and behaviors that shape their experience and facilitate producing relevant discourse. I also collected some genres and documents. The findings showed that (1) collaboration characterized the culture within which PR performs its duties and activities and produces relevant discourse, and (2) the two-way asymmetrical model best represents the PR practice in the university examined. Besides filling the gap identified here, the study contributes to theory and practice in the field. It benefits those who teach public relations writing and the institution itself as it evaluates how excellent the PR practice in that institution is

Generalized PIC detector for distributed STBC under quasi-synchronization

In this paper, we propose a Generalized Parallel Interference Cancelation (G-PIC) approach for the detection of D-STBC under Quasi-Synchronization in the case of any number of relay nodes with just statistical information about time misalignment. While as, most researches assume perfect synchronization between the relay nodes for the detection of D-STBC which is hard to achieve. This approach proved to be very effective to mitigate the degradation in the system performance due to the imperfect synchronization. The numerical simulations, for the proposed approach, showed that in just three iterations we can achieve performance close to the D-STBC with perfect synchronization
