Secondary cluster head based SEP in heterogeneous WSNs for IoT applications
Authors: Hossan Arif , Islam Jahidul
Published: June 2024

A wireless sensor network (WSN) consists of specialized sensor nodes that perform sensing services for Internet of Things devices with limited battery power. As the replacement or recharging of batteries is not possible, energy consumption becomes the most important design issue in WSNs. The energy‐efficient routing protocol gets the most priority in such energy‐constrained networks. The utilization of clustering‐based routing protocols like stable election protocol (SEP) has gained much attention as the network's lifetime is significantly improved due to the clustering of sensor nodes. Moreover, the inclusion of a secondary CH (SCH) is beneficial when the member node with the most remaining energy performs data aggregation and reduces the energy burden of the CH. This article characterizes SEP and Prolong SEP (P‐SEP) protocols and then extends them by incorporating SCH, which ensures balanced energy consumption. The performance of the proposed Extended SEP and Extended P‐SEP protocols has been analysed regarding stability period, network lifetime, energy usage and throughput. The simulation results demonstrate that the proposed protocols outperform state‐of‐the‐art protocols like P‐SEP, Modified SEP (M‐SEP) and SEP. In particular, the stability period of Extended SEP and Extended P‐SEP has improved up to 42% and 89%, respectively, compared to M‐SEP.
A general matrix decomposition approach with application to stabilization of networked systems with stochastic sampling and two‐channel deception attacks
Authors: Li Yizhen , Hu Zhipei , Deng Feiqi , Su Yongkang , Li Guangjie
Published: June 2024

This study is concerned with the stabilization analysis and controller design for networked systems with stochastic sampling and two‐channel deception attacks. First, we give a general matrix decomposition approach which is applicable to scenarios where the system matrix contains complex‐value eigenvalues. Then, a discrete stochastic framework is established for a class of networked systems which considers the joint effects of sampling errors and two‐channel deception attacks. Utilizing the matrix decomposition approach introduced in this study, it becomes feasible to decouple the expectation operations for specific coupling matrices characterized by substantial nonlinearity and randomness. Based on this, a stabilization controller is constructed that ensures the exponential mean‐square stability of the resulting discrete stochastic system. Finally, three simulation examples are provided to validate the effectiveness of the proposed approach.
A high precision estimation algorithm for multi‐channel wide‐area surveillance ground moving target indication mode based on maximum likelihood method
Authors: Yan He , Xu Wenshuo , Liu Hui , Hao Jialin , Min Zhou , Zhu Daiyin
Published: June 2024

A high precision estimation algorithm for ground moving targets in multi‐channel wide‐area surveillance ground moving target indication systems is proposed based on maximum likelihood method. The main concept of this novel algorithm is to estimate the azimuth angle of the detected targets using maximum likelihood method with the space steering vector formed by the estimated interferometric phase extracted from the mainlobe clutter region of the real data. Through this novel algorithm, the effect of channel errors among the multi‐channels can be well reduced. Simulation experiments demonstrate the effectiveness of the proposed algorithm.

The mackerel scad, Decapterus macarellus, is a one of pelagic fish that holds significant market price for the citizens of West Java. Despite this, there has been a puzzling decrease in catches recently. This study describes the reproductive biology of mackerel scad, D. macarellus, in the southern waters of western Java. Mackerel scad samples were collected once a month from July to December 2022 at three locations: Ciwaru Fish Landing Base, Palabuhanratu Nusantara Fisheries Port, and Binuangeun Fish Landing Base. A total of 1,000 fish specimens were obtained, consisting of 544 males (125–331 mm Fork Length, FL) and 456 females (124–322 mm FL). The number of males and females was imbalanced, indicating a discrepancy in the expected 1:1 ratio. The mackerel scad has a varying reproductive potential, with the number of eggs ranging from 35,391 to 167,915. Mature males and females were found from July to December, with the highest GSI occurring between August and November, indicating reproductive season from July to December and spawning peaks from August to November. The estimated sizes at which males and females reach first maturity were 238 mm and 240 mm, respectively. We recommend increasing gear mesh size to reduce catches of immature individuals, as the first catch was smaller than the size of the first matured gonads.

Sponges are animals that can produce bioactive compounds. This use needs to be accompanied by sponge cultivation techniques to avoid decreasing the availability of sponge colonies in nature. This study aims to determine the growth rate and survival rate of sponges Aaptos suberitoides and Petrosia nigricans in a recirculation system and to determine the process of wound healing due to transplantation. The research was carried out in September – November 2010 at the Central Laboratory for Marine Science Studies – IPB University, North Jakarta. Sponges are taken from natural habitats and then transplanted into maintenance ponds. The center of the transplanted sponge fragment is passed through a polyethylene rope which is used as a substrate for the sponge. The survival of Petrosia nigricans is decreasing rapidly every week. At the 6th, week the viability of Petrosia nigricans was 0%. Meanwhile, Aaptos suberitoides has a value of 100% with several fragments of 20. The results of measurements of the Petrosia nigricans sponge for 12 weeks show an average and standard deviation of growth rate in length of -0.04±0.24 cm/week and width of 0.02±0.16 cm/week. Meanwhile, the Aaptos suberitoides sponge is 0.06±0.07 cm/week and 0.05±0.09 cm/week wide. Signs of wound closure in Petrosia nigricans were visible on the fourth day after transplantation, while Aaptos suberitoides experienced wound closure on the second day after transplantation. The measurement value for ammonia in the pool is 0.9542 mg/L, nitrate is 0.3544 mg/L, nitrite is 0.0060 mg/L and salinity is 28-38 0/00, and the temperature is 27-29 °C. The sponge Aaptos suberitoides has a better growth response and has a wider survival tolerance than the sponge Petrosia nigricans in maintaining survival in the recirculation system.

Kappaphycus alvarezii seaweed was widely cultivated in Southeast Sulawesi. However, due to deteriorating water quality, E. denticulatum is gradually becoming its successor. This study aimed to observe three aspects: the activities of Eeucheuma. denticulatum farming based on nine criteria, the adoption level of the Standard Operational Procedure (SOP), and to outline tasks to increase the production of E. denticulatum. The study involved interviewing 59 seaweed farmers using questionnaires. The results showed that among the nine criteria observed, four—seed selection, transportation of seeds, cultivation method, and maintenance monitoring—fall into the highly adopted category, exceeding 70%. One criterion, cultivation method, falls within the medium adoption range (50-69%). Three criteria—farmer profile, farm unit profile, and postharvest documentation and traceability—remain in the low adoption category (<50%). Several future programs need to be addressed, including providing guidance, training, and assistance to farmer groups, managing plastic bottle waste to enhance environmental friendliness, and improving documentation and traceability of seaweed farming.

Authors: Liu Longhui , Wu Chengfeng , Zhao Qiuhong , Wang Longxin
Published: June 2024

With the increasing public awareness of environmental protection, corporate social responsibility has become an important component of sustainable development and competitive advantage for many enterprises. Although there are many studies on corporate social responsibility in the supply chain, there is still a lack of research on the impact of corporate social responsibility on various decision-makers in the competitive green supply chain dominated by upstream enterprises. Therefore, taking into account the greenness and corporate social responsibility, the paper proposes three Stackelberg game models with the two-echelon supply chain consisting of two competing manufacturers and one socially responsible retailer. We develop a series of propositions and corollaries to determine the optimal solutions and offer some managerial insights. The main novelties and contributions of the paper can be demonstrated in two aspects. First, the paper simultaneously considers the impact of competition intensity and CSR level on wholesale prices, retail prices and greenness level. Second, the paper discusses the impact of two manufacturers with different market positions investing in green products on the profits and utility of supply chain members. Numerical illustrations prove that the level of corporate social responsibility is negatively correlated with retailer profitability and the retailer achieve the highest profits when sub-dominant manufacturer produces green products.

Authors: Yao Xintong
Published: June 2024

The process of a company’s IPO application passing the SEC’s review and successfully raising funds from the public by issuing shares on the stock exchange signifies that the company has become a public company and its shares can be listed and traded on the stock exchange. However, the IPO process is actually quite complex, and there are numerous roles involved in the IPO, and a small mistake related to the conduct of the IPO can result in the company not being able to go public. The Securities and Futures Commission (SFC) has some basic requirements for the issuance conditions of the proposed listed company, which gives the proposed listed company an order to ensure that its business system is complete and has the ability to operate independently directly to the market, so that it can have a more definite answer to the success or failure of the IPO. Based on this, the article clarifies the meaning of IPO, and the conditions that the company needs to have and its importance, and lists several factors one by one, such as pricing, efficiency, cost, and stock offering.

Authors: Zhang Ranyanduo
Published: June 2024

Corporate philanthropy is an effective means to help society reduce the various inequalities phenomena and promote social justice. The present research surveys about this topic focus on corporate donations or management but pay less attention to philanthropy methods and corporate foundations. The establishment and development of corporate foundations have become indispensable means for enterprises to engage the philanthropic activities. Therefore, this paper explores the conceptual development, establishment motives, objectives, operational process, and ultimate effectiveness of corporate philanthropic foundations to address the problem of unequal allocation of social resources. In this research, taking the Tencent Public Philanthropy Foundation as an example, and finds that a joint public welfare approach can better promote the establishment of charitable projects. For instance, Tencent Philanthropy Foundation has partnered with One Foundation, the former provides technical and financial support for future classroom projects, while the latter provides professional services and follow-up. The findings suggest that this joint public welfare collaboration is worthy of being used widely by corporate welfare foundations, because the collaboration can play a positive role due to a clear division of labour and professional means in philanthropy projects, and it also could be a new corporate philanthropic strategy in the future.

Research on the Effect of Rwanda Gender Quotas on Political Representation and Optimizing Strategy
Authors: Fan Ho Sio
Published: June 2024

This essay examines the effect of Rwanda's gender quotas on political representation, especially in the Rwandan government, and proposes a few optimizing strategies for it to develop. Rwanda is a developing and post-genocide country in Sub-Saharan Africa, in which the average progress in gender equality is low. However, Rwanda outstands and ranks exceptionally high in gender equality, which largely depends on its gender quotas. Therefore, it is valuable to look at this country, which shows great controversy at the regional level. This essay mainly relies on the Literature Research Method, including the use of academic articles, reliable websites, and news reports to conduct the research. It is concluded that the effect on substantive and descriptive women's political representation of the Rwanda gender quota is quite complex and needs improvement. Utilizing party/ legislative gender quotas with rank order or switching the gender quotas to men are two feasible suggestions for Rwandan gender quotas. Through this study, a more critical perspective on gender quotas could be gained. Also, it inspires more thoughts on how gender quotas in post-genocide developing countries could survive and thrive.

Published: June 2024

Many polyprenylated acylphloroglucinols with fascinating chemical structures and intriguing biological activities have been identified as key to phytochemicals isolated from Garcinia, Hypericum, and related genera. In the present work, two chiral, tautomeric, highly-oxygenated polyprenylated acylphloroglucinols tethered with acyl and prenyl moieties on a bicyclo[3.3.1]nonanetrione core were isolated from the 95% ethanolic extract of Garcinia gummi-gutta fruit. The structures of both compounds were elucidated based on the NMR and MS data with ambiguity in the exact position of the enol and keto functions at C-1 and C-3 of the core structure. The structures of both polyprenylated acylphloroglucinols were established as a structurally revised guttiferone J and the new iso-guttiferone J with the aid of gauge-independent atomic orbital NMR calculations, CP3 probability analyses, specific rotation calculations, and electronic circular dichroism calculations in
combination with the experimental data. The structures of both compounds resemble hyperforin, a potent activator of the human pregnane X receptor. As expected, both compounds showed strong pregnane X receptor activation at 10 µM [7.1-fold (guttiferone J) and 5.0-fold (iso-guttiferone J)], explained by a molecular docking study, necessitating further in-depth investigation to substantiate the herb-drug interaction potential of G. gummi-gutta upon co-administration with pharmaceutical drugs.

Urolithin A is a gut metabolite of ellagitannins and reported to confer health benefits, e.g., by increased clearance of damaged mitochondria by macroautophagy or curbed inflammation. One targeted cell type are macrophages, which are plastic and able to adopt pro- or anti-inflammatory polarization states, usually assigned as M1 and M2 macrophages, respectively. This flexibility is tightly coupled to characteristic shifts in metabolism, such as increased glycolysis in M1 macrophages, and protein expression upon appropriate stimulation. This study aimed at investigating whether the anti-inflammatory properties of urolithin A may be driven by metabolic alterations in cultivated murine M1(lipopolysaccharide) macrophages. Expression and extracellular flux analyses showed that urolithin A led to reduced il1β, il6, and nos2 expression and boosted glycolytic activity in M1(lipopolysaccharide) macrophages. The pro-glycolytic feature of urolithin A occurred
in order to causally contribute to its anti-inflammatory potential, based on experiments in cells with impeded glycolysis. Mdivi, an inhibitor of mitochondrial fission, blunted increased glycolytic activity and reduced M1 marker expression in M1(lipopolysaccharide/urolithin A), indicating that segregation of mitochondria was a prerequisite for both actions of urolithin A. Overall, we uncovered a so far unappreciated metabolic facet within the anti-inflammatory activity of urolithin A and call for caution about the simplified notion of increased aerobic glycolysis as an inevitably proinflammatory feature in macrophages upon exposure to natural products.
Spezielle medikamentöse und interventionelle Therapieverfahren der hypertrophen Kardiomyopathie
Authors: Seggewiß Hubert , Batzner Angelika
Published: June 2024

Die hypertrophe Kardiomyopathie (HCM) ist die häufigste genetische kardiale Erkrankung mit einer Prävalenz von 0,2–0,6% und einer ausgeprägten pathologischen, pathophysiologischen und klinischen Varianz. Aufgrund der therapeutischen Möglichkeiten stehen die bei 70% der betroffenen Patient*innen vorhandene dynamische linksventrikuläre Obstruktion und die seit einigen Jahren in den Vordergrund getretene linksventrikuläre Hyperkontraktilität im Vordergrund des Interesses. Die symptomatische, nicht obstruktive HCM wird entsprechend den Therapieempfehlungen der Herzinsuffizienz behandelt. Therapie der ersten Wahl bei symptomatischer hypertropher obstruktiver Kardiomyopathie (HOCM) sind kardioselektive Betablocker und Verapamil als Nicht-Dihydropyridin-Kalziumantagonist. Selbstverständlich sollte aber zuvor der Einsatz gradientensteigender Medikamente vermieden werden. Bei Nichtansprechen ist aktuell der Septumreduktionstherapie mittels perkutaner Alkoholseptumablation oder in
Einzelfällen der chirurgischen Myektomie der Vorzug zu geben. Bei HOCM mit einer Ausflussbahnobstruktion ist die Behandlung mit Myosin-Inhibitoren zugelassen. Ob diese langfristig wegen zahlreicher offener Fragen (Wechselwirkungsspektrum, Risiko der Verschlechterung der systolischen linksventrikulären Funktion mit notwendigen Kontrolluntersuchungen, Kosten) eine flächendeckende Alternative darstellt, kann aktuell nicht beurteilt werden.

Background We assessed efficacy and safety of endoscopic ultrasound-guided biliary drainage (EUS-BD) vs. endoscopic retrograde cholangiopancreatography (ERCP) as first-line intervention in malignant distal biliary obstruction (MDBO).

Methods PubMed/Medline, Embase, and Cochrane databases were searched until 01 /12 /2023 for randomized controlled trials of EUS-BD vs. ERCP for primary biliary drainage in patients with inoperable MDBO. The primary outcome was technical success. Secondary outcomes were clinical success, adverse events, mean procedure time, 1-year stent patency, and overall survival. Relative risk (RR) with 95 %CI were calculated using a random effects model.

Results Five studies (519 patients) were included. RR (95 %CI) for EUS-BD was 1.06 (0.96 to 1.17; P = 0.27) for pooled technical success and 1.02 (0.97 to 1.08; P = 0.45) for clinical success. 1-year stent patency was similar between the groups (RR 1.15, 0.94 to 1.42; P = 0.17), with lower reintervention with EUS-BD (RR 0.58, 0.37 to 0.9; P = 0.01). The RR was 0.85 (0.49 to 1.46; P = 0.55) for adverse events and 0.97 (0.10 to 0.17; P = 0.98) for severe adverse events. On subgroup analysis, EUS-guided placement of lumen-apposing metal stent (LAMS) outperformed ERCP in terms of technical success (RR 1.17, 1.01 to 1.35; P = 0.03). Procedure time was lower with EUS-BD (standardized mean difference –2.36 minutes [–2.68 to –2.05; P < 0.001]).

Conclusions EUS-BD showed a statistically significant lower reintervention rate than ERCP, but with similar technical success, stent patency, clinical success, and safety. Technical success of EUS-BD with LAMS was better than ERCP.

Published: June 2024

Introduction Postcraniotomy headaches are often underestimated and undertreaded. This study aimed to identify if postoperative administration of sumatriptan after minimally invasive craniotomy for clipping an unruptured aneurysm could reduce postcraniotomy headache and improve the quality of postoperative recovery.

Settings and Design Tertiary care center, single-center randomized double-blind placebo-controlled trial.

Materials and Methods Patients who complained of postoperative headaches after minimally invasive craniotomy for clipping of unruptured aneurysms were randomized to receive subcutaneous sumatriptan (6 mg) or placebo. The primary outcome was the quality of recovery measured 24 hours after surgery. Secondary outcomes were total opioid use and headache score at 24 hours after surgery. Data were analyzed using a Student's t-test or the chi-square test.

Results Forty patients were randomized to receive sumatriptan (n = 19) or placebo (n = 21). Both groups had similar demographics, comorbidities, and anesthesia management. The Quality of Recovery 40 score was higher for patients receiving sumatriptan compared to placebo, however, not statistically significant (173 [156–196] vs. 148 [139–181], p = 0.055). Postoperative opioid use between sumatriptan and placebo was lower, but not significant (5.4 vs. 5.6 mg morphine equivalent, p = 0.71). The severity of headache was also not statistically different between the two groups (5 [4–5] vs. 4 [2–5], p = 0.155).

Conclusion In patients undergoing minimally invasive craniotomies for aneurysm clipping, sumatriptan given postoperatively has a nonsignificant trend for a higher quality of recovery. Similarly, there was a nonsignificant trend toward lower postcraniotomy headache scores and opioid scores for the patient given sumatriptan.

Introduction Differentiation between glioblastoma (GBM), primary central nervous system lymphoma (PCNSL), and metastasis is important in decision-making before surgery. However, these malignant brain tumors have overlapping features. This study aimed to identify predictors differentiating between GBM, PCNSL, and metastasis.

Materials and Methods Patients with a solitary intracranial enhancing tumor and a histopathological diagnosis of GBM, PCNSL, or metastasis were investigated. All patients with intracranial lymphoma had PCNSL without extracranial involvement. Demographic, clinical, and radiographic data were analyzed to determine their associations with the tumor types.

Results The predictors associated with GBM were functional impairment (p = 0.001), large tumor size (p < 0.001), irregular tumor margin (p < 0.001), heterogeneous contrast enhancement (p < 0.001), central necrosis (p < 0.001), intratumoral hemorrhage (p = 0.018), abnormal flow void (p < 0.001), and hypodensity component on noncontrast cranial computed tomography (CT) scan (p < 0.001). The predictors associated with PCNSL comprised functional impairment (p = 0.005), deep-seated tumor location (p = 0.006), homogeneous contrast enhancement (p < 0.001), absence of cystic appearance (p = 0.008), presence of hypointensity component on precontrast cranial T1-weighted magnetic resonance imaging (MRI; p = 0.027), and presence of isodensity component on noncontrast cranial CT (p < 0.008). Finally, the predictors for metastasis were an infratentorial (p < 0.001) or extra-axial tumor location (p = 0.035), smooth tumor margin (p < 0.001), and presence of isointensity component on cranial fluid-attenuated inversion recovery MRI (p = 0.047).

Conclusion These predictors may be used to differentiate between GBM, PCNSL, and metastasis, and they are useful in clinical management.

Published: June 2024

Aim This article determines the compliance rates with low-dose aspirin (LDA) and outcomes in a group of pregnant women identified at high risk for preeclampsia (PE) and fetal growth restriction (FGR) at 11 to 14 gestational weeks (GWs) in a rural district of central India.

Methods A single, experienced fetal radiologist assessed all enrolled pregnant women using trimester-specific antenatal screening protocols that included mean arterial blood pressure assessment, and fetal ultrasound and Doppler studies. A trimester-specific individualized risk for preterm PE and FGR was estimated for each woman. Pregnant women categorized as high risk for preterm PE or FGR based on a 1 in 150 criteria at 11 to 14 GW were recommended LDA 150 mg once daily at bedtime. Outcome measures included compliance with LDA assessed, incidence of PE and FGR, preterm delivery (<37 GW), birth weight, stillbirths, and perinatal mortality.

Results The data of 488 pregnant women with longitudinal trimester-specific assessments from 11 to 14 GW till childbirth was analyzed. At the third trimester assessment, 215 (80.83%) of the high-risk women were compliant with LDA. The incidence of PE, FGR, and preterm births was significantly higher in LDA noncompliant women, and the mean birth weight was significantly higher in LDA-compliant high-risk women.

Conclusion Good compliance for LDA is possible in rural populations with adequate counseling. Starting LDA at 11 to 14 GW for high-risk pregnant women lowered the incidence of PE, FGR, and preterm birth rates and improved birth weight in the study population.
