Pemberian Diet Pasca Bedah pada Pasien Kista Ovarium Pasca Bedah Kistektomi: Laporan Kasus
Authors: Anindya Faradhila , Atmaka Dominikus Raditya
Published: December 2024

Latar belakang: Penyakit kista ovarium merupakan keadaan dimana terdapat benjolan yang berisi cairan, nanah atau jaringan padat pada ovarium atau indung telur. Berdasarkan Survei Demografi Kesehatan Indonesia, angka kejadian kista ovarium di Indonesia mencapai 37,2% dan paling sering terjadi pada wanita usia 20-50 tahun. Penanganan kista ovarium dapat dilakukan dengan tindakan operasi kistektomi. Anemia dapat terjadi pada pasien kista ovarium baik karena adanya riwayat genetik, perubahan gaya hidup maupun efek samping dari pembedahan. Proses Asuhan Gizi Terstandar (PAGT) dilakukan untuk memberikan asuhan gizi yang tepat pada pasien kista ovarium setelah melakukan operasi kistektomi.
Tujuan: Mengetahui penerapan Proses Asuhan Gizi Terstandar dengan pemberian diet pasca bedah pada pasien kista ovarium.
Metode: Studi kasus dilakukan bulan Maret 2021 pada pasien RS Bakti Dharma Husada Surabaya. Pengambilan sampel telah ditentukan sebelumnya oleh ahli gizi rumah sakit dan pembimbing magang sesuai kriteria kasus. Metode pengambilan data dilakukan dengan studi literatur dan observasi analitik selama 3 hari pada domain asupan, fisik/klinis, biokimia dan antropometri.
Hasil: Monitoring dan evaluasi didapatkan bahwa terdapat perubahan fluktuatif pada hasil laboratorium, fisik/klinis, dan asupan pasien mengalami peningkatan dalam 3 hari. Asupan makanan pasien mengalami peningkatan signifikan dan dapat mencapai target minimal 70%.
Kesimpulan: Kondisi pemulihan tergolong cukup baik berdasarkan hasil pemantauan asupan makanan meskipun asupan pada hari pertama dan kedua tidak dapat dikategorikan sebagai peningkatan signifikan karena pasien hanya diberikan makanan cair melalui nasogastric tube (NGT). Hasil pemeriksaan fisik/klinis pada hari kedua dan ketiga pasien masih merasa mual, akan tetapi kondisi tersebut tidak mempengaruhi asupan makanan secara keseluruhan.

Post-transplant complications in alcohol- and metabolic-associated steatotic liver disease
Authors: Jadaun Shekhar Singh , Saigal Sanjiv
Published: December 2024

Alcohol-associated liver disease (ALD) and metabolic-associated steatotic liver disease (MASLD)/metabolic-associated steatohepatitis (MASH) are severe liver diseases, with liver transplant being the primary curative treatment option. Transplant recipients with ALD suffer from alcohol use disorder (AUD) and poor drug compliance, which can result in graft injury and even graft loss. Relapse of alcohol consumption, lack of drug compliance, and smoking negatively impact the graft and clinical outcome of ALD-related transplantation patients. Furthermore, these patients are at a higher risk of developing non-hepatic complications such as malignancies, cardiovascular diseases, and other metabolic conditions. The management of these conditions requires pharmacological and behavioral strategies to manage complications as soon as they arise. Critical monitoring of these conditions is also advocated. In patients undergoing transplants for MASLD/MASH, early complications arise in obese and diabetic patients. Late post-transplant complications such as cardiovascular diseases, chronic kidney disease, recurring MASLD/MASH, immunosuppression, and arterial hypertension are reported. Integrating behavioral strategies with diet modification and physical activity is crucial to balance underlying metabolic disorders and improve clinical outcomes. Early steroid withdrawal and low calcineurin inhibitor doses can decrease the risk of post-transplant diabetes, hypertension, and dyslipidemia. Lifestyle modifications and tailored immunosuppression are helpful in the prevention and management of post-transplant recurrent MASLD/MASH.
The Modification of Post-Quantum AJPS-1 Cryptosystem by Changing the Metric
Authors: Yadukha Dariya
Published: December 2024

This paper considers the AJPS-1 post-quantum cryptosystem.A feature of this cryptosystem is the use of arithmetic modulo Mersenne number, in particular, the AJPS cryptosystem uses relations for the Hamming weight of integers modulo Mersenne number.To create a modification of this cryptosystem by changing the metric, relations of the OSD metric for integers modulo Mersenne number were obtained.The paper describes the constructed modification of the AJPS-1 cryptosystem with a changed metric and analyses its advantages compared to the AJPS-1 cryptosystem.This modification allows to increase the variance of the decryption parameter, which improves the resistance of the cryptosystem to ciphertext-only (known ciphertext) attacks aimed at determining the private key.
Application of Large Language Models for Assessing Parameters and Possible Scenarios of Cyberattacks on Information and Communication Systems
Authors: Alekseichuk Lesia , Lande Dmitry , Novikov Oleksii
Published: December 2024

This paper explores the use of large language models (LLMs) to evaluate parameters and identify potential hostile penetration scenarios in corporate networks, considering logical and probabilistic relationships between network nodes. The developed methodology is based on analyzing the network structure, which includes components such as the Firewall, Mail Server, Web Server, administrator and client workstations, application server, and database server. The probabilities of transitions between these nodes during adversarial attacks are determined using a swarm of virtual experts and two sets of prompts aimed at different LLMs. Among the results obtained through the swarm approach are average transition probabilities, which enable modeling the most likely attack paths from both external and internal network origins. Based on logical-probabilistic analysis, penetration scenarios are ranked according to probabilities, execution time, and resource minimization required by attackers. The proposed methodology facilitates rapid response to threats and ensures an adequate level of cybersecurity by focusing on the most probable and dangerous attack scenarios.
On the cryptosystems based on two Eulerian transformations defined over the commutative rings Z2s, s>1
Authors: Ustymenko Vasyl
Published: December 2024

We suggest the family of ciphers sEn, n = 2, 3, ... with the space of plaintexts (Z2^s)^n, s > 1, such that the encryption map is the composition of kinds G = G1 A1 G2 A2, where Ai are the affine transformations from AGLn(Z2^s) preserving the variety (Z*2^s)^n. Eulerian endomorphisms Gi, i = 1, 2, of K[x1, x2, ..., xn] move xi to the monomial term M x1^d(1) x2^d(2) ... xn^d(n), M in Z2^s, and act on (Z2^s)^n as bijective transformations. The cipher is converted to a protocol-supported cryptosystem. Protocols of Noncommutative Cryptography implemented on the platform of Eulerian endomorphisms are used for the delivery of Gi and Ai from Alice to Bob. One can use twisted Diffie-Hellman protocols, which security rests on the complexity of the Conjugacy Power problem, or the hidden tame homomorphism protocol, which security rests on the word decomposition problem. Instead of delivering Gi, Alice and Bob can elaborate these transformations via the inverse twisted Diffie-Hellman protocol, implemented on the platform of tame Eulerian transformations of (Z*2^s)^n. The cost of a single protocol is O(n^3), and the cost of computing the reimage of the used nonlinear map is O(n^2). So, the verification of nt, t ≥ 1, signatures takes time O(nt + 2). Instead of the inverse twisted Diffie-Hellman protocol, correspondents can use the inverse hidden tame homomorphism protocol, which rests on the complexity of word decomposition for tame Eulerian transformations. We use natural bijections between Z2^s and Z2^(s-1), Z2^s and finite field F2^(s-1), and Z2^s and Boolean ring B(s-1) of order 2^(s-1) to modify the family of ciphers or cryptosystems via the change of AGLn(Z2^s) for AGLn(K), where K is one of the rings Z2^(s-1), F2^(s-1), or B(s-1). New ciphers are defined via the multiplication of two different commutative rings Z2^s and K. This does not allow treating them as stream ciphers of multivariate cryptography and using corresponding cryptanalytic techniques. An adversary is not able to use known cryptanalytical methods such as linearization attacks. We discuss the option of changing the elements of AGLn(Z2^s) or AGLn(K) for nonlinear multivariate transformations F of (Z2^s)^n or K^n with a symmetric trapdoor accelerator T, i.e., a piece of information such that the knowledge of T allows computing the value F(p) for an arbitrarily chosen p in P in time O(n^2) and solving the equation of the form F(x) = c for each c in C in time O(n^2).

Authors: Korolev I.
Published: December 2024

The article argues that despite general uncertainty of world economic situation Russia founds itself in sufficiently favorable position for sustainable growth. The main reason is the availability of huge resources, including natural, human, financial, technological, special and administrative. However, in order to successfully utilize these resources for the sake nation’s development Russian economic policy-makers have to solve a number of serious tasks. Essentially, we have to objectively assess the risks that Russia is facing under current conditions. This can help to choose the directions of economic policy that will enable to trigger the most efficient growth factor throughout the whole economic space of the country.

Authors: Singh Manju , Gorasiya Kruti , Modha K. G.
Published: December 2024

The present experiment was carried out to evaluate 142 genotypes of Indian bean for different qualitative and quantitative characters. The genotypes showed considerable variation for flower bud colour, standard and wing colour, pod curvature, pod constriction, pod colour, pod attachment, fresh and dry seed colour, fresh seed shape and dry seed texture. The analysis of variance revealed the significant differences among the mean sum of squares with respect to plant height, pod length, pod width, pod weight and seed yield per plant under study. This showed that a sufficient amount of variability is present within the material under study for these traits. Progenies exhibited higher values of GCV and PCV for seed yield per plant indicating the greater scope of improving this character by applying selection in an appropriate direction. High heritability coupled with high genetic advance as per cent mean were observed for plant height, pod weight and seed yield per plant indicating the role of additive gene effects and less effects of environmental factors on the expression of the traits. Thus, the improvement of these traits could be achieved through direct phenotypic selection.

Published: December 2024

Recent years have seen a resurgence of interest in under-utilized legumes with high nutritional and therapeutic properties. Ricebean are an appropriate option for inclusion in the list of existing legumes. Ricebean seeds are a well-balanced source of constituents that are beneficial to health and combat malnutrition. Although very important from a dietary point of view in Burkina Faso, there is as yet no research into the nutrient composition and antioxidant properties of rice beans. The aim of this study was to analyze the biochemical composition of a ricebean collection. Total of 24 ricebean seed accessions were evaluated for various biochemical traits using official and standard analytical methods. Results showed great variability in protein content (11.493 to 33.852 mg/g) and sugar content (4.207 to 8.48 mg/g). Concentrations of phenolic compounds such as phenols and flavonoids varied respectively from 1.140 to 3.446 mg EQ/g and from 0.559 to 1.322 mg EAG/g. DPPH ranged from 3.285% to 27.018% and FRAP from 2.042 to 35.21 mM EAA/g DM. Correlation coefficient between parameters was calculated to understand the relationship between variables. First three principal components contributed 62.7% of the variation. CAH formed four groups based on levels of macromolecules, ascorbic acid, pigments, phenolic compounds and antioxidants. Accessions RB27, RB10 RB59, RB60 RB127 RB79 showed interesting antioxidant and phenolic activity, high protein, ascorbic acid and sugar content. Results of this study suggest the use of these potential accessions in breeding programs with the main aim of improving the nutritional quality of ricebean.

Published: December 2024

Artificial intelligence (AI) is used in many aspects of life, from personal voice assistants to product recommendations in online stores to advanced diagnostic systems in medicine. All these applications show how AI technology is becoming an increasingly integral part of everyday life. Understanding the basics of AI is key to recognizing its role in traffic management. AI can be used to monitor and control road traffic, prevent traffic jams and road crashes, support vehicle diagnostics, and optimize response times for emergency services and roadside assistance. Particular attention should be paid to reducing the number of fatal road crashes. This goal is to be achieved by integrating AI with autonomous vehicle technology, which should improve or even reduce the number of road accident victims to 0.
EVALUATION OF TIMING CHAIN QUALITY AND ITS EFFECT ON TIMING SYSTEM OPERATION
Authors: WITASZEK Kazimierz , STANIK Zbigniew
Published: December 2024

Internal combustion engines are still the main source of propulsion for automotive vehicles. The timing system plays a very important role in the proper functioning of these engines. One of the widely used technical solutions to drive this system is the timing chain. However, in recent years, there has been a clear trend towards more frequent timing system failures. Many research works have focused on wear analysis or finite element method (FEM) modeling of chains. In contrast, it was decided to carry out a comparative study of the mechanical properties of new timing chains that are commercially available as spare parts for automotive workshops. The present study was carried out on timing system components of the popular Multijet 1.3 diesel engine used in Fiat, Opel, and Suzuki vehicles. Force-elongation curves were obtained for each of the tested chains, allowing their elongation under load to be estimated. In addition, breaking forces were measured, and breaking mechanisms were analyzed to compare the quality of the chains. Numerical parameters were proposed to estimate the quality of the tested chains. The chain tensioning forces resulting from the operation of the hydraulic tensioner were also estimated. The effect of the dynamic forces stretching the chain elastically on the timing accuracy during engine operation was also calculated.
ANALYZING THE IMPACT OF DEMOGRAPHIC FACTORS AND URBAN DENSITY ON MODE CHOICE IN THE GREATER BRISBANE AREA
Authors: HAFENRICHTER Dennis , STERN Steven , RAJAGURU Gulasekaran
Published: December 2024

Understanding the influence of demographic factors and urban density on transportation mode choice is crucial for promoting sustainable mobility in urban areas. This study examines these influences in the Greater Brisbane Area using data from the Queensland Household Travel Survey (QHTS) collected between 2018 and 2023. We apply binomial logistic regression models to analyze how age, gender, employment status, presence of children, and urban density at origin and destination locations affect the likelihood of choosing transportation modes, including car, walking, bicycling, public transport, and Mobility as a Service (MaaS). The results indicate that higher urban density is significantly associated with reduced car usage and increased use of sustainable modes such as walking, public transport, and bicycling. Older individuals are more likely to use cars and less likely to choose active modes, while males have a higher propensity to bicycle compared to females. Employment status also influences mode choice, with employed individuals more likely to drive or use public transport and less likely to walk. Although the number of MaaS users in the dataset is limited, preliminary findings suggest potential higher adoption in high-density areas and among older individuals. These insights provide empirical evidence from Brisbane and have practical implications for urban planners and policymakers. Enhancing infrastructure for sustainable transportation in densely populated areas and considering demographic factors can promote sustainable mobility patterns. Future research should include additional variables such as transportation supply factors and use longitudinal data to explore causal relationships. Investigating the barriers to MaaS adoption in Brisbane would also be valuable for shaping future urban mobility strategies.
SENSITIVITY ASSESSMENT OF A GRADIENT-BASED LEAK LOCALIZATION PROCEDURE FOR PRESSURE SENSOR FAULTS USING A LABORATORY MODEL OF A TRANSMISSION PIPELINE
Authors: OSTAPKOWICZ Paweł
Published: December 2024

This research addresses the topic of leakage localization in liquid transmission pipelines. Particularly, it deals with the standard gradient-based procedure used for performing such a task. The procedure relies on pressure gradient calculations based on pressure data collected from measurement points distributed along the pipeline. This study aimed to verify this procedure regarding its sensitivity to typical systematic errors related to pressure transducers. The primary measure evaluated was the accuracy of the calculated coordinate of a leak spot. The uncertainty of the leak localization result was also estimated following the Guide to the Expression of Uncertainty in Measurement convention. A laboratory model of the pipeline was used to practically implement and test the procedure. During experiments, low-intensity leakages with a level of 0.25–2.00% were simulated. Regarding typical systematic errors, the bias (zero moving) type and the proportional ratio type were considered, which were numerically simulated in the measurement data. The findings reveal how sensitive the examined procedure is in relation to these errors, considering their different levels and scenarios related to used pressure transducers.

Authors: LUPI Marino , CONTE Daniele , SARNO Maurizio , ZOPPI Sara , FARINA Alessandro
Published: December 2024

In this paper, the resilience of the Italian deep sea shipping (DSS) container routes in situations of severe crisis (in this case, the COVID-19 pandemic), is studied quantitatively, distinguishing gateway and transshipment DSS routes. In addition, DSS container routes in the pandemic period (i.e., from 2020 to 2023), have been compared to those before the pandemic, in particular from 2011 to 2019. The results have shown that while gateway traffic decreased from 2019 to 2023, due to the reduction of the demand connected to the pandemic, transshipment traffic has increased, in contrast to the trend before the pandemic that has shown a considerable reduction from 2011 to 2019. The results also show that the naval gigantism phenomenon increased from 2011 to 2019 but seems to have stopped since 2019. This analysis is highly important in the field of maritime studies, as it covers the two most important phenomena concerning maritime transport that have occurred over the past 10 years (i.e., naval gigantism and the COVID-19 pandemic).
Health and the Work Absence Gap Across Employment Sectors in the United States
Authors: Bednarczuk Michael
Published: December 2024

Those in the public sector in the United States are historically known to have more work absences than those in the private sector. While long attributed to various individual-level or organizational-level characteristics, there has not been an examination of the role that physical and mental health may play in impacting that difference. Using data gathered from the National Health Interview Study, descriptive statistics found that those in the public sector tend to be in worse physical health but better mental health than those in the private sector. While Poisson models found that health did not impact the likelihood of those in the public sector having more absences than those in the private sector, a Blinder-Oaxaca decompositional analysis found that the majority of the gap in absences across sectors can be attributed to the distribution of characteristics across the private and public sectors. These findings suggest that demographic and organizational differences across the public and private sectors, not simply health, are the main determinants of the gap in work absences across sectors.

Published: December 2024

Los rumiantes, debido a las características fermentativas de su sistema digestivo, generan y emiten metano a la atmósfera, un gas de efecto invernadero que contribuye al calentamiento global. Debido a la importancia que tiene la ganadería en España, es necesario plantear estrategias que reduzcan dichas emisiones. Una de ellas, es la utilización de almidones vítreos en la formulación de dietas de rumiantes. Su menor degradabilidad ruminal, da lugar a una disminución de la producción de metano. El objetivo de este estudio fue evaluar el comportamiento fermentativo de un sistema de mezclas cebada/maíz, así como, de un concentrado comercial de cebo de terneros con diferentes niveles de maíz. Para ello, se llevó a cabo un análisis in vitro de producción de gas y metano. Las mezclas de cebada/maíz se fermentaron durante 18h y los concentrados durante 18 y 96h. Para las mezclas ceba/maíz, la menor producción de gas se obtuvo con 100% maíz (207,97ml/g), aumentando el metano 0,11mlCH4/g por cada punto porcentual de cebada añadido. Respecto a los concentrados, tras 18h de fermentación la menor producción de gas y metano se asoció al control y al concentrado con mayor nivel de maíz respectivamente. Tras la fermentación 96h el concentrado con mayor nivel de maíz registro los mayores niveles de producción de gas y metano. Ambos cereales muestran diferentes perfiles fermentativos y metanogénicos in vitro, limitando la producción de gas y metano al incluir maíz en concentrado de terneros.

En esta exhaustiva exploración de la precisión en la definición de los estándares de raza canina, el artículo emplea herramientas analíticas avanzadas, como las correlaciones de Spearman y los residuos de Procrustes, para evaluar las relaciones entre variables zoométricas, fanerópticas y de comportamiento. Las correlaciones de Spearman cuantifican las asociaciones entre rasgos, guiando la priorización de elementos para estándares de raza sólidos, mientras que los residuos de Procrustes añaden una dimensión geométrica, revelando sutiles desviaciones morfológicas. La integración sinérgica de análisis estadísticos y geométricos marca un cambio de paradigma en la selección de estándares de raza, capacitando a los interesados para navegar la complejidad de las variables. La evaluación sistemática de diversos rasgos físicos y temperamentales en perros asegura una comprensión holística, y la aplicación de medidas estadísticas en razas de perros de las Islas Baleares identifica elementos obligatorios y revela combinaciones que indican la falta de rasgos distintivos. Los hallazgos ofrecen valiosas perspectivas para criadores, entusiastas y jueces, guiándolos para adherirse a estándares reconocidos y preservar las cualidades distintivas de la raza.

Las técnicas de recongelación permiten darle al semen otros tratamientos y lograr una mayor eficiencia en la reproducción animal, como realizar técnicas de sexado en semen previamente congelado. El objetivo de este estudio fue evaluar el efecto de la recongelación del semen bovino, sobre la integridad de la membrana plasmática, morfología, viabilidad y motilidad individual. Se utilizó semen de tres toros Brahman colectados en tres ocasiones (n=9) cada uno con electroeyaculador; los eyaculados fueron congelados en nitrógeno líquido (-196°C) utilizando el diluyente Triladyl®. Se analizaron tres tratamientos: Semen Fresco Diluido (SFD), Semen Congelado Descongelado (SCD) y Semen Congelado Descongelado Recongelado (SCDR). Se aplicaron las tinciones Spermac (Minitube®) para morfología, BLOM para viabilidad y la prueba de HOST (endósmosis celular) para integridad de membrana plasmática. Hubo diferencias significativas (P≤0.05) entre SFD, SCD y SCDR para los porcentajes de motilidad individual (92.5%, 65.42% y 46.25%), porcentaje de espermatozoides vivos (84.18%, 61.70% y 48.21%), porcentaje de espermatozoides normales (97.60%, 95.97% y 93.46%) y porcentaje de espermatozoides con endosmosis positiva (82.50%, 50.13% y 31.58%) respectivamente. Bajo las condiciones de este estudio, el proceso de recongelación del semen bovino disminuye la motilidad individual, la viabilidad y afecta la integridad de la membrana plasmática, sin embargo, puede ser una alternativa viable cuando es aplicado solo a eyaculados que hayan presentado inicialmente una motilidad individual en fresco ≥ 80%.

O objetivo deste estudo foi caracterizar morfologicamente e avaliar a variabilidade fenotípica do grupo genético de frango Peloco utilizando técnicas multivariadas, bem como descrever a curva de crescimento dessas aves com base em modelos não lineares. As características mais importantes para a variação entre as aves foram comprimento da crista (47,38%), para os machos, e comprimento do peito (41,27%), para as fêmeas. Entre os machos, os dois primeiros componentes principais foram necessários para explicar 85,94% da variação fenotípica e os três primeiros componentes representaram 86,61% da variação entre as fêmeas. O modelo de Gompertz apresentou o melhor ajuste aos pesos, sendo selecionado para descrever o crescimento das aves Peloco. A taxa de crescimento absoluto máxima foi de 15 g/ dia, identificada aos 83 dias de idade, enquanto que o ponto de inflexão da curva foi observado aos 84 dias de idade. A idade de abate sugerida para o grupo genético Peloco varia de 120 a 150 dias, garantindo um peso de mercado apropriado. O grupo genético Peloco apresentou variabilidade fenotípica para as características avaliadas, sendo adequado à seleção. Além disso, manejo nutricional específico é necessário para a melhoria da curva de crescimento nestas aves.
Building Professional Relationships and Student Confidence through Early Childhood Graduate Practitioner Competencies

Published: December 2024

This paper reports on how Early Childhood Graduate Practitioner Competencies (ECGPCs) impact on professional relationships and develop bidirectional confidence in the practical abilities of Early Childhood Studies (ECS) students in England. The study adopted an interpretive approach, seeking views through questionnaires (n=38) which were administered, through purposeful sampling, to students, mentors and academics from three universities in England offering Early Childhood Studies (ECS) degrees with ECGPCs. Findings suggest that the ECGPCs enabled focused placement students, with stakeholders recognising the potential for confidence and increased professionalism through the direction that the ECGPCs provide. In contexts of rapid change in Early Childhood policy this article argues the importance of the ECGPCs and of placement to support the graduate professional identity of the early childhood workforce. Interlinking and evidencing knowledge from research and practice enable graduates to articulate and have competencies in; ‘what they do’, ‘how they do ‘it’’ and essentially ‘why they do ‘it’’’. This is essential in promoting graduate relational/collegial professionals and advocating for stronger societal recognition and valuing of young children and the professionals working with them. With the ECGPCs being a new initiative within the United Kingdom, this study is unique in that it begins the research conversation around the success and challenges that this new initiative brings to the suite of Early Childhood (EC) qualifications.
A simplified method to a three-dimensional spherical reciprocal cloak via shell-based dielectric metamaterials

Published: December 2024

In the past, all the cloaks based on transformation optics or scattering cancellation posed some insufficiencies, for example, only two-dimensional concealment in experiments for the transformation-optics-based cloak and custom made and small hidden objects for scattering cancellation. Therefore, in this work, we proposed a spherical reciprocal cloak composed of shell-based dielectric metamaterials that could be realized by sophisticated ceramic manufacturing procedure. Field distributions of the integrated reciprocal cloaks without and with multiple objects suggested that although some scattering field appeared, yet, the normalized differences of the scattering cross section when hidden objects were put within the cloak was only 8.44% and 1.11% along q and f directions, and field distributions for the cloak without and with hidden objects revealed an average relative deviation of 7.2%, revealing the capability of the cloak to conceal multiple arbitrary objects. Furthermore, the design procedure of the reciprocal cloak was further simplified since the thicknesses of the shell played the major role in the performances of the cloak and were the same within the same regime according to the previous simulation results. Again, the simplified cloak demonstrated the normalized differences of the scattering cross section of 29.93% and 4.58% along q and f directions and an average relative deviation of 6.1%. We believe such design strategy could be extended to other transformation optics based optical devices such as concentrators, rotators, illusion devices, etc., and pave a route toward a practical three-dimensional concealment in the field of stealth technology.

Gliomas, the most common brain tumors, present significant challenges in treatment, particularly glioblastoma multiforme (GBM), due to their infiltrative nature and difficulty in achieving gross total resection (GTR). Accurate assessment of surgical resection extent is critical for patient prognosis and survival. This study investigates the utility of cerebrospinal fluid (CSF) circulating tumor DNA (ctDNA) as a quantitative biomarker for evaluating glioma resection extent and patient prognosis. We employed next-generation sequencing (NGS) to profile genomic alterations in both tumor DNA and CSF ctDNA collected pre- and post-operatively. A high concordance rate (83.50%) between CSF ctDNA and tumor tissue was found, particularly for key somatic mutations such as TERT, TP53, PTEN and IDH1. Post-operative ctDNA analysis revealed a significant reduction in mean mutant allele frequency (MAF) and tumor mutational burden (TMB). Apart from non-GTR and multiple lesions, patients who exhibited a ≥ 90% reduction in mean MAF or in the MAF of driver mutations post-surgery demonstrated significantly improved overall survival (OS). These findings suggest that CSF ctDNA effectively represents the genetic profile of gliomas and serves as a sensitive measure for surgical resection efficacy and patient prognosis, highlighting its potential as a non-invasive biomarker for enhancing post-operative management in glioma patients.
Cross-cultural measurement invariance and comparison of the mobile phone dependence questionnaire (MPDQ) between adolescents from mainland China and Hong Kong
Authors: Wang Hanbin , Chin Fung , Chen Chun
Published: December 2024

Background
Mobile phone dependence (MPD) is a serious public health concern in schools. To advance cross-cultural understanding of MPD, this study examined factor structure, measurement invariance, and latent mean differences of the mobile phone dependence questionnaire (MPDQ) across mainland Chinese and Hong Kong adolescents.
Methods
A total of 918 middle school students (588 boys and 310 girls; Mage = 13.58, SD = 1.46) were involved, comprising 367 mainland Chinese adolescents and 551 Hong Kong adolescents.
Results
The three-factor structure of the MPDQ, proposed by previous research conducted in Hong Kong adolescents, was also supported in mainland Chinese adolescents. Configural, partial metric, and partial scalar cross-cultural measurement invariance were all achieved. Hong Kong adolescents reported higher scores on all MPD factors than their mainland Chinese counterparts with large effect sizes.
Conclusions
The findings highlight the cross-cultural similarities and differences of MPD among adolescents in mainland China and Hong Kong. The MPDQ is culturally sensitive to measure MPD in both cultures, while certain items may need further cultural adaptation. Moreover, Hong Kong adolescents demonstrated more disordered thoughts and behaviors associated with MPD than mainland Chinese adolescents. Implications for using the MPDQ for assessing and understanding the MPD from diverse cultural backgrounds are discussed.
