Influence of Hydrogen Embrittlement on the Wierbiecki- Xu Failure Strain Criterion - Application to A Local Strain-Based Design
Authors: Alric Lucas , Pluvinage Guy , Capelle Julien
Published: January 2024

This paper aims to quantify the influence of hydrogen embrittlement on Wierzbicki and Xue (W-X) model parameters. This model has 4 parameters which have been obtained by tensile tests on smooth specimens, tensile notch specimens, single notch tensile specimens (SENT) and pure shear specimens. Hydrogen embrittlement has been obtained by electrolytic method. Application of the (W-X) model has been done to get the local resistance used to predict failure by the Volumetric Method (VM). An example is given for the case of an embedded pipe submitted to service pressure and lateral seismic displacement. The effect of this displacement is then assimilated to the shearing of the straight section of the pipe. The pipe shows a corrosion defect considered a semi-elliptical crack. The influence of hydrogen embrittlement on local strain resistance and safety factors is discussed.

Published: January 2024

Anastomotic Leakage (AL) remains the main cause of post-esophagectomy morbidity and mortality. Early detection can avoid sepsis and reduce morbidity and mortality. This study evaluates the diagnostic accuracy of the NUn-score and its components as early detectors of AL. This single centre observational cohort study included all esophagectomies from 2010-2020. C-reactive Protein (CRP), Albumin (Alb) and White cell count (WCC) were analyzed and Nun-scores calculated. Area under the curves (AUC) were used to assess their predictive accuracy. Seventy-four of the 668 patients (11%) developed an AL. CRP and the NUn-score proved to be good diagnostic accuracy tests on POD2 (CRP AUC:0,859; Nun-score AUC:0,869) and POD4 (CRP AUC:0,924; Nun-score AUC:0,948). A 182mg/L CRP cut-off on POD4 yielded a 87% sensitivity, 88% specificity, a negative predictive value (NPV) of 98% and a positive predictive value (PPV) of 47,7%. A Nun score cut-off>10 resulted in 92% sensitivity, 95% specificity, 99% NPV and 68% PPV. Albumin and WCC have limited value in the detection of post-esophagectomy AL. Elevated CRP and a high NUn score on POD4 provide a high accuracy to predict AL after esophageal cancer surgery. Their high negative predictive value allows to select patients who can safely proceed with enhanced recovery protocols.
Induction Motor Improved Vector Control Using Predictive and Model Free Algorithms Together with Homotopy-based Feedback Linearization
Authors: Costin Madalin , Lazar Corneliu
Published: January 2024

Usually, the vector control of the induction machine (IM) is done by using cascade control structures with conventional linear PI controllers, the inner loop being designed for current control, and the outer loop for rotor flux and speed control. In this paper, starting from the dq model of the IM with the rotor magnetic flux space vector aligned along the d axis, advanced control algorithms are proposed for the two control loops of the cascade structure. For the current inner loop, after the decoupling control of the two dq currents, predictive algorithms with constraints are used to control and limit the currents. Since the outer loop has a nonlinear affine multivariable plant model, a homotopy-based variant of feedback linearization is used to obtain a non-singular decoupling matrix of the feedback transformation even when the rotor flux is zero at the start-up of the motor. During the continuous variation of the homotopy parameter, the model of the plant is variable, in which case the model free algorithms are properly used to control the flux and speed of the IM. The comparative analysis obtained for the cascade structure with conventional PI controllers and advanced algorithms, respectively, shows that the last lead to improve the dynamical performance of the IM.
Theoretical Derivation and Calculation of Electron Charge
Authors: Deng Chaojun , Wei Xiaoyun
Published: January 2024

In this paper, we propose an assumption of which the relation between electron and phonon is discussed and investigated based on the experiment of γ photon and electric interconverting with each other. We calculated the charge of a particular standing wave topology with Maxwell’s equation rotated in accordance space with the SO3 transformation. The derived charge value is 1.6035 × 10E−19C around 0.0826% different from the experimental data, indicating the proposal is a promising theory to explain the origin of charge and spin of electron particle. Electron spin angular momentum comes from the orbital angular momentum of photon rotation (electromagnetic field rotation), and electron charge comes from photon, that is, the space-time rotation effect of electromagnetic wave.
Breakthrough in Blastic Plasmacytoid Dendritic Cell Neoplasm Cancer Therapy Owing to Precision Targeting of CD123
Authors: Zanotta Serena , Galati Domenico
Published: January 2024

Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN) is a rare and aggressive hematologic cancer originating from the malignant transformation of plasmacytoid dendritic cell precursors. This malignancy progresses rapidly, with frequent relapses and a poor overall survival rate, underscoring the urgent need for effective treatments. However, diagnosing and treating BPDCN have historically been challenging due to its rarity and the lack of standardized approaches.
Recognizing BPDCN as a distinct disease entity is recent, and standardized treatment protocols are yet to be established. Traditionally, conventional chemotherapy and stem cell transplantation have been the primary methods for treating BPDCN patients. Advances in immunophenotyping and molecular profiling have identified potential therapeutic targets, leading to a shift towards CD123-targeted immunotherapies in both clinical and research settings.
Ongoing developments with SL-401, IMGN632, CD123 Chimeric Antigen Receptors (CAR) T-cells, and Bispecific Antibodies (BsAb) show promising advancements. However, the therapeutic effectiveness of CD123-targeting treatments needs improvement through innovative approaches and combining treatments with other anti-leukemic drugs. Exploring combinations, such as CD123-targeted immunotherapies with azacitidine and venetoclax, is suggested to enhance antineoplastic responses and improve survival rates in BPDCN patients.
In conclusion, this multifaceted approach offers hope for more effective and tailored therapeutic interventions against this challenging hematologic malignancy

Published: January 2024

Nurses’ caring behaviors are affected by several determinants. The aim of this study was to explore the factors affecting nurses’ caring behaviors. Nurses (N=309) from three public general hospitals in Greece completed the Factors of Nurses’ Caring Behaviors Scale. The data analysis was carried out with the Statistical Package for the Social Sciences (SPSS), version 26.0. Demographic and occupational data were, also, recorded. The statistical significance level was set at <0.05. The total mean score on the FNCB Scale was 100.4 (SD±26). The dimensions of Workplace Circumstances (Mean: 24.6, SD±8.0) and Workload/Management (Mean: 24.5, SD±6.4) were the most important factors of caring behaviors. On the opposite, nurses perceived the dimensions of Patients’ Demographic Characteristics (Mean: 9.3, SD± 4.4) and Patients’ Clinical Characteristics (Mean: 12.5 SD±4.2) as the least important factors. Men scored higher than women in the dimension of Patients’ Demographic Characteristics (t=3.022, p=0.003). Secondary Education Graduates scored lower in the dimensions of Workplace Circumstances (Tukey, p=0.035) and Workload/Management (Tukey, p=0.033) than MSc/Ph.D. Graduates. Nurses of surgical departments scored lower in total score than ICU nurses (Tukey, p = 0.026). Workplace conditions, workload, and management seem to be the most important factors in nurses’ caring behaviors.

Authors: Powell Jonah , Conlon Jenny , Chivers Paola , Cripps Ashley
Published: January 2024

Workplace exercise programs are imperative for improving employee health and wellbeing. Employee cognition and productivity can also benefit from such programs; however, the practical application of interventions to influence these outcomes is poorly understood. This research aimed to assess the suitability of a university Staff Fitness Program for improving employee productivity and cognition. Forty-seven participants were included in the study, comprising 27 Staff Fitness participants and 20 control group participants. A two (groups) x three (time-points) between-subjects/within-subjects design was employed over 14 weeks, comprising ten weeks of once-weekly exercise intervention for Staff Fitness participants. All participants completed the Victoria Stroop Colour and Word Test and the Health and Work Questionnaire at each time-point, to assess cognition and productivity, respectively. Participants also completed the International Physical Activity Questionnaire (short form) at time-point one, three and during training weeks (excluding week one) to measure physical activity. Appropriate T-tests and non-parametric equivalents were used to assess group differences in outcome measures and across time-points. There were no significant between group or longitudinal differences indicative of improved productivity or cognition. The Staff Fitness group demonstrated a non-significant improvement (Z = 73.00, p = .055) in physical activity from time-point one (M = 1540.93 MET-min-week, SD = 1083.74) to three (M = 2077.32 MET-min-week, SD = 1401.48) with a large effect size (d = 0.97), while control group physical activity significantly decreased (Z = 10.00, p = .013). The present Staff Fitness Program benefited employees by improving physical activity, despite no improvements in productivity or cognition. Future research should further explore the application of workplace exercise programs and the manipulation of exercise parameters to show improvements in employee productivity and cognition.

Authors: Bernat Tomasz , Flaszewska Sylwia , Lisowska Renata , Szymańska Katarzyna
Published: January 2024

Energy transition is one of the greatest challenges facing humanity today. All micro, small, medium and large enterprises in operation will have to face it, and some can al-ready boast the first successes in this regard. This paper focuses on the involvement of these smallest players in energy transition. Micro and small entities are the largest part of the economy, having a great influence on its development. Looking at the wide scale of their activities, these entities are distinguished by a specific owner-manager relationship. This means that the final decision-making is influenced by business goals, but also by the manager's approach, their awareness of changes, and personal and other factors. Based on a structured and standardized survey questionnaire, the research was carried out using the Computer-Assisted Telephone Interviewing technique between April and May 2022 among owners of micro and small enterprises operating in Poland. The survey showed that active engagement of micro and small enterprises in energy efficiency initiatives is related to their market success and financial health.
Nonlinear Dynamics in HfO2/SiO2-Based Interface Dipole Modulation Field-Effect Transistors for Synaptic Applications
Authors: Miyata Noriyuki
Published: January 2024

In the pursuit of energy-efficient spiking neural network (SNN) hardware, synaptic devices lev-eraging emerging memory technologies hold significant promise. This study investigates the ap-plication of the recently proposed HfO2/SiO2-based interface dipole modulation (IDM) memory for synaptic spike timing-dependent plasticity (STDP) learning. Firstly, through pulse measure-ments of IDM metal-oxide-semiconductor (MOS) capacitors, we demonstrate that IDM exhibits an inherently nonlinear and near-symmetric response. Secondly, we discuss the drain current re-sponse of a field-effect transistor (FET) incorporating a multi-stack IDM structure, revealing its nonlinear and asymmetric pulse response, and suggest that the degree of the asymmetry depends on the modulation current ratio. Thirdly, to emulate synaptic STDP behavior, we implement dou-ble-pulse-controlled drain current modulation of IDMFET using a simple bipolar rectangular pulse. Additionally, we propose a double-pulse-controlled synaptic depression that is valuable for optimizing STDP-based unsupervised learning. Integrating the pulse response characteristics of IDMFETs into a two-layer SNN system for synaptic weight updates, we assess training and classification performance on handwritten digits. Our results demonstrate that ID-MFET-based synaptic devices can achieve classification accuracy comparable to previously re-ported simulation-based results.

This study outlines a comprehensive examination of risks and hazards in three egg sorting and packing stations, covering the entire process from supplier selection and evaluation to egg delivery in chain stores. The analysis is conducted within the framework of Codex Alimentarius and GFSI-integrated food safety programs. Salmonella is the greatest significant threat. To enhance the Hazard Analysis of Critical Control Points (HACCP), preparatory programs were incorporated into the quality management system (QMS) by monitoring and assessing the biological, chemical, and physical threats according to Code Alimentarius and further integrated into GFSI food safety programs, including food authenticity and food defense. The procedure offered sophisticated preventive tools, hand-on at any time, for eliminating, reducing, or mitigating the risks encountered in egg packing and sorting facilities.
The Clinical Concurrence of Migraine and Transient Global Amnesia: “Migramnesia”?
Authors: Fratalia Lauren , Larner Andrew J.
Published: January 2024

Complaint of transient impairment or loss of memory as an attendant feature in some migraine attacks has long been recognised. In some cases, migraine may be a trigger or precipitating factor for the syndrome of transient global amnesia (TGA). However, the exact frequency of this concurrence is unknown, perhaps related to the absence from the International Classification of Headache Disorders (ICHD3) of amnesia or memory loss symptoms in association with migraine, unlike the situation with epileptic seizure (migralepsy) or stroke (migrainous infarction). Similarly, headache has generally been regarded as an incidental feature of TGA, reported in about 10% of cases. We present further examples of TGA in the context of migraine headache; consider possible reasons why this concurrence might be under-recognised, such as the retrograde amnesia characteristic of TGA; review possible shared pathogenetic mechanisms; and suggest a new terminology, “migramnesia”, which may encourage clinicians to address the possible significance of migraine in the context of an episode of TGA.

Published: January 2024

The aim of this study was to explore the perceived impact of artificial intelligence (AI) on radiographers’ activities and profession in Switzerland. A survey conducted in the UK, translated into French and German, was disseminated through professional bodies and social media. The participants were Swiss radiographers (clinical/educators/ researchers/students) and physicians working within the medical imaging profession (radiology/nuclear medicine/radiation-oncology). The survey covered five sections: demographics, AI-knowledge, skills, confidence, perceptions about the AI impact. Descriptive, association statistics and qualitative thematic analysis were conducted. A total of 242 responses were collected (89% radiographers; 11% physicians). AI is being used by 43% of participants in clinical practice, but 63.8% of them did not feel confident with AI terminology. Participants viewed AI as an opportunity (57.2%), while 18.5% considered it as a threat. The opportunities were associated with streamlining repetitive tasks, minimizing errors, increasing time towards patient-centred care, research, and patient safety. The significant threats identified were reduction on work positions (22.6%), decrease of the radiographers’ expertise level due to automation bias (16.4%). Participants (68.3%) did not feel well trained/prepared to implement AI in their practice, highlighting the non-availability of specific training (87.6%). 93% of the participants mentioned that AI education should be included at undergraduate education program. Although most participants perceive AI as an opportunity, this study identified areas for improvement including lack of knowledge, educational supports/training, and confidence in radiographers. Customised training needs to be implemented to improve clinical practice and understanding of how AI can benefit radiographers.
Differentiating Red From Red: A guide to understanding Dermatological lesions
Authors: Desai Dev , Gamal Abouarab Ahmed
Published: January 2024

Diagnosing skin lesions can be a challenging task. Dermatologic lesions are hard to differentiate especially for an untrained eye. However, carefully analyzing every aspect of the lesion can help clinicians reach an accurate diagnosis. If diagnosed correctly with the naked eye, many lesions can be treated without the need for further histopathology or investigations. Those aspects include morphology, color, distribution, configuration and arrangement, texture and consistency, and any evolutions or changes within the lesion. Clinicians must also contextualize those lesions into the patient’s history and overall systemic symptoms and signs. Risk factors should be taken into consideration and whether there are evolutionary changes in the lesions. Clinicians should also look for patterns as they might be the key to diagnosis. If definitive diagnosis is still not reached, biopsy, dermatoscopy, cultures, skin scrapings, patch testing, blood tests, and imaging studies may be necessary for confirmation. Integrating these methods with clinical judgment and patient history significantly enhances the accuracy of diagnosis in dermatology. Treatment for dermatologic lesions varies depending on the underlying cause.

Published: January 2024

In addition to changes in the amount of rain, changes in land use upstream are considered a factor that directly affects the maximum runoff flow in a basin, especially in areas that have experienced floods and flash floods. This research article presents the application of the SWAT model to assess runoff in areas that have experienced flash floods, in order to analyze the proportion of land use change to the maximum runoff. Study areas that had experienced flash floods were in 3 basins in Thailand (Lam Saphung Basin, Phrom River Basin, and Chern River Basin Part 1 which is a subbasin of the Nam Chi River Basin). This study analyzed two main factors that influence runoff in the river basin: Changes in rainfall and changes in land use by considering 2 simulation situations.: (1) Changes in land use affecting runoff assessed by considering land use maps in 2006, 2008, 2010, 2015, 2017, 2019, and 2021 when using rainfall data only in the year 2021 for all cases, and (2) Changes in the amount of rainfall influencing runoff by considering the rainfall record in 2006, 2008, 2010, 2015, 2017, 2019, and 2021 when using the land use data only in the year 2021 for all cases. The results of the study found that the SWAT model can be effectively applied to estimate annual runoff in areas that have experienced flash floods under 8 parameters with R2 values of 0.74, 0.82 and 0.74 for the Lam Saphung River Basin and the Phrom River Basin and the Chern River Basin Part 1 respectively. In addition, it was found that the proportion of land use changes that involved changes from forest areas to residential areas was the greatest from 2008 to 2010 in the Phrom River Basin and Chern River Basin Part 1. This resulted in an increase in the maximum runoff amount of 77.78% and 46.87%, respectively. When land use was constant, it was found that the rainfall in 2010, which was the highest, also had the greatest impact on the runoff in all 3 areas.

Published: January 2024

(1) Background: Bats are reservoirs and vectors of significant zoonotic diseases. Our study focuses on understanding the role of bats as reservoirs and carriers of coronaviruses, given their epidemiological significance and the recent global health crises stemming from coronavirus outbreaks. (2) Methods: We conducted virological screening of bats hibernating in military bunkers at the Natura 2000 site "Nietoperek" in Western Poland. This involved collecting and analyzing oral and anal swab samples from 138 bats across six species, using a combination of pan-coronavirus and SARS-CoV-2 specific PCR assays. (3) Results: Out of 138 bats, only one anal swab tested positive for coronavirus. However, we were not able to obtain genomic sequence from the sample. No SARS-CoV-2 was detected in any of the samples. The low prevalence of coronavirus in the studied colony contrasts with higher rates found in other regions and may be influenced by the physiological and behavioral conditions of bats during hibernation. (4) Conclusions: Hibernating bats may show a low prevalence of coronavirus, potentially due to the hibernation process itself. This finding indicates that hibernating bats may not be the most optimal subjects for screening zoonotic pathogens. However, continuous monitoring of bat populations for emerging and reemerging diseases is recommended for a comprehensive epidemiological understanding.

Authors: Gil Olaf , Fenske Benjamin , Bremert Thomas , Vollmer Marcus , Scharf Christian , Busch Chia-Jung , Blaurock Markus
Published: January 2024

Introduction: Obstructive sleep apnea (OSA) is not only common in the general population but even more so in patients with tumors of the head and neck region. Untreated, it leads to reduced quality of life, increased daytime sleepiness, and other comorbidities. The aim of this study was to determine the difference in the occurrence of OSA in the patient population with head and neck tumors compared to the general population as represented by the Trend cohort of the Study of Health in Pomerania (SHIP) , and to assess the influence of tumor treatment.

Methods: Between July 2018 and December 2021, preoperative polysomnography was conducted in 47 patients with histologically confirmed squamous cell carcinoma in the oropharynx, hypo-pharynx, or larynx. A follow-up polysomnography was performed in 23 patients 2-11 months af-ter completing treatment. The collected data was correlated with tumor treatment and tumor size.
Results: Of the included patients, 43 were male and four were female. Age ranged from 54 to 90 years. The pretherapeutic measurement found no significant difference in the prevalence of a pathologically elevated apnea-hypopnea index (AHI) in our patients compared to the SHIP-Trend cohort. In the follow-up measurement after treatment completion, a significant deterioration in AHI was observed. Initially, 70 % of patients had an AHI > 5, after therapy this increased to 87 %. The effect was particularly pronounced in the group of patients with advanced tumor stages who had received primary chemoradiation.

Conclusion: OSA is a relevant condition in patients with head and neck cancer. Tumor treatment can lead to an increased occurrence of sleep-related breathing disorders, especially in patients with advanced tumor stages undergoing primary chemoradiation. Additional studies are neces-sary to better understand the exact mechanism involved.

Published: January 2024

Abstract: Circuit breakers are affected by multiple lightning strikes after the breaker has been tripped and can break down again, which will reduce the life of the circuit breaker and threaten the stable operation of the power system. Aiming at this problem, the paper obtained the temperature diffusion process of the inrush current process of circuit breaker opening and breaking through the schlieren technique, and combined with the existing image recognition technology to obtain the temperature characteristics of the airflow in the air gap of the contact, and the characteristics of the airflow flow. The results of the study show that the circuit breaker breakdown process generates a shock wave with a velocity approximately equal to the speed of sound under the same conditions. The maximum velocity of the airflow boundary diffusion is about 1/4 of the speed of sound under the same condition, and it decays very fast, reducing to the airflow drift velocity within 10ms after breakdown. The maximum temperature of the thermals is concentrated between 6000 and 8000 K and the temperature change is approximately inversely proportional to the square of time. The research provides the basis for the design of circuit breaker contact structure, opening speed optimization method, interrupter chamber and insulation design optimization.
A Life Course Perspective on the Sexual Development of Young Intersex People
Authors: Marinus Mir Abe , Cense Marianne
Published: January 2024

Previous research showed that intersex people face specific challenges in their sexual development, including uncertainties or confusion about their gender, a negative genital self-image, and hesitance to engage in romantic and sexual relationships. However, in-depth knowledge of a central period of this development, adolescence, is missing. In our qualitative study, we explore which factors influence the relational and sexual development of intersex youth and what elements contribute to a positive development. We interviewed eighteen intersex persons aged 18-38. We identified three main themes: (1) intersex experiences, (2) the described sexual and relational life course, and (3) factors influencing a positive development. Our findings show that intersex youth face many obstacles to their relational and sexual development, many of which related to healthcare. However, their life stories also illuminate how healthcare professionals but also parents, friends, partners, teachers and others can make a substantial difference in intersex lives by breaking normative, binary thinking on sex and gender.

Authors: Ashraf Humaira , Nawaz Mamona , Jhanjhi NZ
Published: January 2024

Mobile Ad hoc Networks (MANETs) play an important role in the technological era by enabling wireless communication in dynamic and infrastructure-free contexts. Because of Manet’s unique qualities and decentralized nature, MANETs are subject to many attacks such as the Blackhole attack, grey hole attack, Byzantine attack, Wormhole attack, and Sybil attack. Sybil attacks pose a substantial risk to MANETs. A Sybil attack occurs when a malicious node impersonates many identities inside the network, resulting in the creation of multiple suspicious nodes that appear as independent entities. This study presents a thorough analysis of the literature on the detection of Sybil attacks on MANETs. To find gaps in the literature, current surveys are also looked at. Also taken into consideration are several contemporary systems built on distinct techniques. In terms of throughput, detection rate, low energy consumption, packet delivery ratio, and end-to-end latency, some recent methods-based approaches are also evaluated severely. To address the stated state-of-the-art issues in Sybil attack detection, this paper suggests ML-based strategies as the most suitable answer. Machine learning has huge potential for effective wireless network management. According to the researcher, this is the first comprehensive assessment of ML-based techniques for Sybil attack detection in wireless networks. Finally, we considered the unsolved issues in Sybil assault detection in wireless networks.

Badan Kependudukan dan Keluarga Berencana Indonesia diberikan target utama untuk menurunkan angka kelahiran menjadi 2,1 anak dari 1000 kelahiran wanita usia subur. Selain daripada itu program Keluarga Berencana juga diyakini dapat mencegah resiko terjadinya stunting pada balita melalui upayanya dalam mengatur kehamilan melalui penggunaan alat dan obat kontrasepsi. Adapun salah satu masalah yang saat ini dialami oleh Provinsi Aceh adalah tingginya angka unmet need. Unmet need sendiri merupakan kondisi tidak terpenuhinya kebutuhan ber-KB bagi Pasangan Usia Subur (PUS) yang ingin menunda kehamilan ataupun tidak menginginkan anak lagi. Tujuan dari kajian ini adalah untuk mengetahui hal-hal yang menyebabkan tingginya persentase unmet need di Provinsi Aceh sehingga target untuk menurunkan persentase unmet need dapat diturunkan. Penelitian ini dilakukan dengan menggunakan mix method. Adapun sampel lokus yang dipilih adalah 4 Kab/Kota yang memiliki persentase jumlah PUS dengan status sangat tinggi di Provinsi Aceh, yaitu: Kota Banda Aceh Kota Subulussalam, Kab. Singkil dan Kab. Pidie yang berjumlah 200 responden. Berdasarkan hasil wawancara dan temuan pada penelitian ini diketahui faktor yang menentukan tingginya angka unmet need di Provinsi Aceh antara lain disebabkan karena informasi masyarakat yang keliru terhadap alat dan obat kontrasepsi; kurangnya sinergi antara PKB dan tenaga kesehatan; rendahnya kualitas komunikasi kader dan keterbukaan PUS yang didata dalam memberikan informasi.

One of the tasks of banking institutions is to channel funds to the public through loan products. Banking institutions transfer the risk of non-performing loans to insurance companies and then partially reinsured to reinsurers. The purpose of this study is to determine the non-proportional reinsurance threshold based on the risk of loss of the 20% largest loan principal, using the Tail Value-at-Risk (TVaR) method. The threshold value will be estimated using a sample of 5,000 loans principal. The loan characteristics can be described by a Mixture Gamma Distribution consisting of components with different weights and parameters. The weights and parameters are 19% from the Gamma distribution with parameters α = 2.45 and β = 0.04, 34.5% from Gamma with parameters α = 8.29 and β = 0.07, and 46.5% from Gamma with parameters α = 30 and β = 0.13. Analysis using TVaR produces a threshold value of 274.9 million rupiah. In real cases, if the claim value exceeds 274.9 million rupiah. The insurance company will bear a value of 274.9 million rupiah and the reinsurer will bear the difference in the size of the claim against the threshold limit.

Published: January 2024

Clustering is a process of grouping data into several groups (clusters) so that data in one cluster has a homogeneous level of similarity and data between clusters has heterogeneous similarity. A common example of a clustering algorithm is K-Means Clustering. Compared with classical clustering algorithms, the biclustering algorithm is a two-dimensional data grouping process. The biclustering algorithm functions to find data submatrices, namely row subgroups and column subgroups that have high correlation. One example of a biclustering algorithm is Cheng and Church Biclustering (CC Biclustering). The aim of this research is to evaluate the performance of the biclustering algorithm against classical clustering algorithms. Analysis applied to CC Biclustering and K-Means Clustering to identify distribution patterns of Indonesian export goods in the period 2013 to 2022. Based on research results, the optimal scenario for the K-Means algorithm is scenario 2, that is the application of the 7 cluster K-Means algorithm with pre- processing data scaling. Meanwhile, the optimal scenario for the CC Biclustering algorithm is scenario 1, that is the application of the CC Biclustering algorithm with a tolerance value of 0.10 with data scaling pre-processing. However, from these two scenarios, based on the MSR/Volume value, it was concluded that the best scenario is scenario 1 in the application of the CC Biclustering algorithm which has an MSR/Volume value of 0.077.

“Por el de pila famosa” (DQ, I, 1): modesta conjetura cervantina
Authors: Baldissera Andrea
Published: January 2024

La lección “por Hepila famosa”, que se asomó en el primer capítulo de la princeps del Quijote y luego desapareció durante siglos, sustituida por la enmienda trivializadora “por hacerla famosa” (ya desde la segunda edición de Juan de la Cuesta, 1605), acuciado a varios filólogos y críticos de nuestros días, instando a buscar miradas hermenéuticas capaces de justificar el enigmático nombre propio. La insatisfacción originada por las principales propuestas avanzadas hasta ahora –que se debaten aquí– obliga a considerar nuevas perspectivas. Por ello, se intenta mostrar que “Hepila” es, muy probablemente, síntoma y consecuencia de un proceso de deterioro textual que generó una falsa difficilior. Finalmente, se plantea una conjetura que se funda tanto en las circunstancias materiales como en la lógica discursiva del Quijote, el usus scribendi y la ironía de Cervantes.

Introduction: Esophagectomy is considered as procedure with highest morbidity and mortality; yet one of the main stream treatment for esophageal cancers. Genetics, age, sex, gender are unmodifiable risk factors for esophageal cancers, it is one of the most common cancers occurring in the world. Most important features of oesophagectomy are perioperative risk assessment, pulmonary morbidity, ventilation strategies, thoracic epidural analgesia, goal directed fluid therapy, ERAS protocol, management of cardiovascular complications. Thoracic epidural analgesia helps in reducing the systemic inflammatory response, by decreasing pain stimulus and post-operative pain control. Case Report: A 62 year old, 50 kgs man was posted for transthoracic esophagectomy presented with complaints of difficulty in swallowing and generalized weakness. Patient medical history was not significant. Patient had received 4 cycles chemotherapy (paclitaxel and carboplatin). Anaesthetic management was planned with the aim of proper analgesia, minimum respiratory complications following ERAS protocol. Conclusion: Pre-operative anesthesiological evaluation is mandatory in order to stratify and optimize any medical condition. During surgery, protective ventilation and judicious fluid management are the cornerstones of intraoperative “protective anesthesia”. Post-operative care should be provided by an intensive care unit or high-dependency unit depending on the patient’s condition, the type of surgery endured and the availability of local resources.

The patient waiting in the Emergency room for both the patient assessment and patient transfer out to the assigned destination (ward or intensive care unit) are major indicators in healthcare reform. This is generally assessed by patient satisfaction score. This score is usually lowest in the emergency room worldwide, mostly due to the patient load in the emergency room. We aim to assess the patient satisfaction score and the cause of delay in patient shifting out of the emergency room in our institute as the emergency department is the first point of contact in patients.

Coronary angiography and catheterisation of the heart are most widely performed tests for the diagnosis and quantification of coronary artery diseases, identification of structural abnormalities of the heart (including valvular heart diseases), and hemodynamic status monitoring. There are very high risks and complications associated with these procedures that relate to the patient’s conditions and also, the skill and operational abilities of the operator. In this case report we see a very interesting case of fractured coronary guide wire retention in the heart, its migration to distant artery and later its retrieval through surgical approach.
