The Exciting Star of the Berkeley 59/Cepheus OB4 Complex and Other Chance Variable Star Discoveries

A study is presented regarding the nature of several variable stars sampled during a campaign of photometric monitoring from the Abbey Ridge Observatory: 3 eclipsing binaries, 2 semiregulars, a luminous Be star, and a star of uncertain classification. For one of the eclipsing systems, BD+66 1673, spectroscopic observations reveal it to be an O5 V((f))n star and the probable ionizing star of the Berkeley 59/Cep OB4 complex. An analysis of spectroscopic observations and BV photometry for Berkeley 59 members in conjunction with published observations imply a cluster age of ~2 Myr, a distance of d = 883+-43 pc, and a reddening of E(B-V) =1.38+-0.02. Two of the eclipsing systems are Algol-type, but one appears to be a cataclysmic variable associated with an X-ray source. ALS 10588, a B3 IVn star associated with the Cepheid SV Vul, is of uncertain classification, although consideration is given to it being a slowly pulsating B star. The environmental context of the variables is examined using spectroscopic parallax, 2MASS photometry, and proper motion data, the latter to evaluate the membership of the variable B2 Iabe star HDE 229059 in Berkeley 87, an open cluster that could offer a unique opportunity to constrain empirically the evolutionary lineage of young massive stars. Also presented are our null results for observations of a sample of northern stars listed as Cepheid candidates in the Catalogue of Newly Suspected Variables.

Knowledge, Attitude and Practice of Cervical Cancer Screening among Reproductive Age Group Women in Ekpoma, South-South Nigeria

Background: Cervical cancer screening is an effective preventive approach to reduce the incidence of women developing cervical cancer. The utilization of Papanicolaou smear and HPV DNA testing has provided doctors with valuable tools for the early detection of women at risk. Method: This study involved 350 respondents and employed a multi-stage sampling technique. Data was collected using questionnaires. Descriptive statistics were used to analyze the data using IBM SPSS version 21.0 software. The Chi-square test was utilized to test for associations, with a significance level set at p &lt; 0.05. Result: The findings revealed a lack of knowledge regarding cervical cancer and screening. Only 136 (38.9%) of the respondents had heard about cervical cancer, and only 50 (14.3%) were aware of cervical cancer screening. Also, 184 (52.6%) had a positive attitude towards being screened, and 176 (50.3%) believed that they did not require their spouse's consent for screening. Regarding the practice of cervical cancer screening, only 22(6.3%) of the participants had undergone a cervical screening. Furthermore, no statistically significant correlation was found between sociodemographic variables and individuals' knowledge, attitudes, and practices regarding cervical cancer screening. Conclusion: This study highlights the poor knowledge regarding cervical cancer and screening among the participants. However, a majority of them expressed willingness to undergo cervical cancer screening and recognized the importance of early detection for better treatment outcomes.

Dynamic metabolic imaging of hyperpolarized [2‐<sup>13</sup>C]pyruvate using spiral chemical shift imaging with alternating spectral band excitation

Purpose In contrast to [1‐ 13 C]pyruvate, hyperpolarized [2‐ 13 C]pyruvate permits the ability to follow the 13 C label beyond flux through pyruvate dehydrogenase complex and investigate the incorporation of acetyl‐coenzyme A into different metabolic pathways. However, chemical shift imaging (CSI) with [2‐ 13 C]pyruvate is challenging owing to the large spectral dispersion of the resonances, which also leads to severe chemical shift displacement artifacts for slice‐selective acquisitions. Methods This study introduces a sequence for three‐dimensional CSI of [2‐ 13 C]pyruvate using spectrally selective excitation of limited frequency bands containing a subset of metabolites. Dynamic CSI data were acquired alternately from multiple frequency bands in phantoms for sequence testing and in vivo in rat heart. Results Phantom experiments verified the radiofrequency pulse design and demonstrated that the signal behavior of each group of resonances was unaffected by excitation of the other frequency bands. Dynamic three‐dimensional 13 C CSI data demonstrated the sequence capability to image pyruvate, lactate, acetylcarnitine, glutamate, and acetoacetate, enabling the analysis of organ‐specific spectra and metabolite time courses. Conclusions The presented method allows CSI of widely separated resonances without chemical shift displacement artifact, acquiring multiple frequency bands alternately to obtain dynamic time‐course information. This approach enables robust imaging of downstream metabolic products of acetyl‐coenzyme A with hyperpolarized [2‐ 13 C]pyruvate. Magn Reson Med 71:2051–2058, 2014. © 2013 Wiley Periodicals, Inc.

The implications and applicability of a QAM high data rate modem

The art of designing successful HF communications systems is growing more complex but with much greater dividends. Many new technologies are now available. Traditional 75 bps broadcast data links are giving way to 19.2 kbps data links using commercial off the shelf HF radios. The developments in STANAG 5066 and Mil Std 188-110B have produced waveforms that allow user data rates up to 9600 bps in a single 3 kHz sideband (SSB) and 19.2 kbps in independent sideband (ISB). This paper reflects on the issues and data collected from actual over-the-air (OTA) testing. These tests measured characteristics over HF skywave paths between Cedar Rapids, Iowa, Ottawa, Canada (1336 km) and San Diego, California (2467 km).

A Sensing-Based Cooperative Position Scheme for Perceptive Mobile Network towards 6G

Integrated Sensing and Communication (ISAC) is a promising technology which will be the core of future 6G network. ISAC will integrate sensing capability into current communication-only mobile network, with the sharing and integration of transmit signals, time-frequency resources, major hardware and signal processing modules. The base-station-orientated sensing network, or also known as perceptive mobile network (PMN), will empower the base station to operate beyond communication and provide seamless sensing services. In this paper, we focus on extracting sensing parameters of multiple targets for accurate positioning in the PMN scenario. Specifically, we first implement Multiple Signal Classification (MUSIC) and Root-MUSIC for velocity and distance estimation, and compare their performances with OFDM-Radar method. Furthermore, based upon the sensing parameter estimation, we propose an integrated localization scheme that utilize both active and passive sensing signals. We also investigate the impact of resource allocation on positioning performance. The effectiveness of three sensing algorithms and proposed cooperative positioning method are verified using link-level simulation platform adopted from latest 3GPP standards.

Immunization of Sheep With Larval Antigens of Lucilia cuprina

Sheep were immunized with antigens extracted from third-instar larvae of L. cuprina. This procedure produced substantial titres of circulating antibody as measured by solid-phase radioimmunoassay or immunodiffusion or by both techniques. However, immunization did not confer protection against subsequent implant challenge with first-instar larvae. In vitro studies indicated that pooled sera from immunized sheep (mean immunodiffusion titre = 3) significantly reduced larval survival. Antigen specificity and the modulating effects of concomitant humoral responses to larval challenge are discussed in relation to the findings.

Bilateral Pseudo-Kaposi Sarcoma in Upper Limbs

Acroangiodermatitis or pseudo-Kaposi sarcoma is an angioproliferative, self-limited entity that includes a group of diseases, congenital or acquired, with cutaneous lesions similar to Kaposi sarcoma (KS). This term can lead to confusion because it comprises several entities that are completely different, nonetheless, it has an important clinical value as it guides the diagnosis and management of these patients. We report the case of a 67-year-old patient with lesions of acroangiodermatitis in both forearms secondary to arteriovenous shunts from hemodialysis. Doppler ultrasound showed a former arteriovenous fistula in addition to the one already known. Immunohistochemical study showed CD34+ staining in endotelial cells and absence of HHV-8 expression.

Correlation and function in Cerec 3.

The Correlation and Function modes are valuable assistants for an anatomical occlusal surface design in the Cerec method. Because of the extensive improvements of the Cerec 3 software, particularly the Correlation mode considerably simplifies the clinical procedure. Correlation works so accurately that even with small restorations, provided that the initial situation is anatomically correct, a second exposure is worthwhile, since the intraoral corrections on the occlusal surface are reduced to a minimum by the use of Correlation. The Correlation algorithm also brings somewhat incongruent exposures into exact alignment. With this principle and the enormous progress made in the hardware, further exceptional development of the Cerec occlusal surface can be expected.

Acute Kidney Injury Prevention

Acute kidney injury (AKI) is a condition associated with significant morbidity and mortality. The incidence of AKI is increasing due to predisposing factors (sepsis, nephrotoxins, and hypotension). This review will focus on the risk stratification of patients vulnerable to developing AKI in whom the timing of the insult is known (e.g., cardiac surgery, contrast exposure) as well as the clinical context in which the risk intensifies. The review will also focus on preventive measures and different pharmacological agents for preventing AKI. Clinical trials of pharmacological agents for the prevention of AKI are challenging. While many compounds are promising in preclinical testing, only a few compounds have been tested, and none has shown consistent results in clinical trials. This is in part due to the lack of large and well-designed trials. With well-designed clinical trials, the use of novel biomarkers and innovative therapeutic strategies, we are on the verge of improving outcomes in the prevention of AKI.

Dataset: Scleractinian coral larval settlement, post-settlement survival, and substrate fouling data

This dataset compiles the raw and processed data supporting the manuscript "Antifouling capacity of substrate materials and their effects on settlement and post-settlement survival of scleractinian corals".The research evaluated the antifouling performance of different substrate materials and their impact on the larval settlement and post-settlement survival of scleractinian corals.<br><b>Abstract</b><br>In coral reef restoration, sexual reproduction is a key methodology to enhance coral population recovery. However, significant challenges remain during the post-settlement phase, where primary polyps are particularly vulnerable to predation, sedimentation, and competition with fouling organisms. To mitigate these challenges, the development of substrates with antifouling properties has been proposed. These substrates aim to reduce colonization by fouling organisms, thereby minimizing competition with the coral primary polyps. This study evaluated the efficacy of different substrate materials in the settlement and post-settlement survival of scleractinian corals, as well as their antifouling capability. Three experiments were conducted, each assessing distinct substrate materials with their corresponding treatments. Settlement and post-settlement survival of <i>Acropora palmata</i> and <i>Orbicella faveolata</i>, as well as the colonization of fouling organisms, were evaluated. Results indicated that larval settlement occurred across the different treatments derived from the tested substrate materials. However, none of these substrate materials enhanced post-settlement survival in <i>ex situ</i> tests. Some substrate materials exhibited lower fouling colonization after two months at sea. Ongoing research evaluating these antifouling substrate materials is a critical component of early coral restoration approaches, with the potential to significantly influence coral survival on the reef after outplanting.

Determinants of commitment and opportunism of institutional investors’ behaviour: an empirical investigation on Robo-voting Phenomenon

Purpose of the paper: Recent research identifies a troubling number of institutional investors that automatically follow the advice of their proxy advisors so that they can prove to have complied with their fiduciary duties in a practice known as robo-voting. Therefore, our central research questions are: How could the characteristics of institutional investors affect robo-voting phenomenon? How could robo-voting phenomenon favour the creation of new opportunistic behaviour, changing the scope of shareholder engagement? Methodology: Our paper directly addresses these questions by using ANCOVA (Analysis of Covariance) to test the effect of characteristics of institutional investors on the dependent variable under study. We use a manually constructed sample of coverage information from 123 Annual General Meetings held by large Italian companies in the 4-year period 2015 to 2018 and the voting reports of three proxy advisors. Findings: We show that such voting based on robo-voting phenomenon is restricted to specific types of institutional investors and it may be highlighted as a negative aspect of a duty to ‘demonstrate’ engagement on the part of institutional investors. Specifically, this duty could depend on location, strategy and category of institutional investors. Research limits: We refer only to the Italian market and it may be considered as a peripheral market by investors. Practical implications: We argue that legal enforcement of the conceptual and operational spectrum of engagement duties currently sits uncomfortably upon institutional investors and proxy advisors. Originality of the paper: We think it is important to consider how to promote shareholder engagement in general in a European context and at the same time curb negative activism by some shareholders.

DETERMINATION OF CATHETER WALL HEAT TRANSFER IN CARDIAC OUTPUT MEASUREMENT BY THERMODILUTION*

SUMMARY 1. A model system of the thermal dilution technique was used to determine in vitro the loss of thermal indicator across different sizes of polyethylene catheters. 2. Thermal indicator loss (caloric gain by the indicator fluid or caloric loss by the catheter) per unit length of catheters (H/L) increased as a function of the outer radius (OR) of the catheters. Linear regression analysis gave the following equation: H/L=0‐337OR+0‐073 ( r =0‐88, P &lt;0‐05). 3. Thermal indicator loss per unit surface area (H/SA) decreased almost linearly with the following regression equation: H/SA =–1‐860 OR+0‐364 ( r =0‐97, P &lt;001). 4. Thermal indicator loss per unit volume contained in the catheter (H/vol) decreased exponentially according to the following equation: H/vol = 89‐le −25.4(OR) ( r =0‐97, P&lt;001). 5. This study indicates that there is a measurable loss of thermal indicator during injection corresponding to a loss of between 9 and 16% (for a 11.5 cm length of PE 50 and PE 240) of the required calories for warming the injectate to 37°C. Data is provided for correction of heat loss across the wall of a given length and diameter of polyethylene tubing.

A backbone assisted hybrid key management scheme for WSN

Wireless Sensor Networks (WSNs) are receiving increased focus due to their applicability to crucial applications like military, healthcare, habitat monitoring etc. However, wireless communication poses additional threats to the critical information being sent over the wireless media. Therefore there is a dire need to have a secure way of communication for a WSN. Public Key Cryptography (PKC) holds the capacity to provide much needed security to WSN; however it is considered an expensive option for already constrained network. On the contrary, Symmetric Key Cryptography (SKC) is considered ideal for resource hungry WSN, nevertheless it has drawbacks too. In this paper we present a secure and reliable key management scheme for backbone assisted WSNs. Our scheme deploys both the symmetric and public key cryptography. We utilize PKC for node authentication and to share the initial secret key. SKC is then used for subsequent communication. We analyze performance of our proposed scheme and compare it with the existing approaches. We prove that our scheme is much more secure and stable and outperforms other schemes in terms of communication and memory overheads.
