Published: September 2024

Background: Neuropathologic studies of brains from autopsy series show tau inclusions (pretangles, neuropils threads, neurofibrillary tangles) are detectable more than a decade before amyloid-β (Aβ) deposition in Alzheimer’s disease (AD) and develop in a characteristic manner that forms the basis for AD staging. An alternative position views pathological tau without Aβ deposition as a ‘primary age-related tauopathy’ (PART) rather than prodromal AD. Recently, an early focus of tau inclusions in the Ammon’s horn second sector (CA2) with relative sparing of CA1 that occurs before tau inclusions develop in the entorhinal cortex (EC) was proposed as an additional feature of PART. Objective: To test the ‘definite PART’ hypothesis. Methods: We used AT8-immunohistochemistry in 100μm sections to examine the EC, transentorhinal cortex (TRE), and Ammon’s horn in 325 brains with tau inclusions lacking Aβ deposits (average age at death 66.7 years for females, 66.4 years for males). Results: 100% of cases displayed tau inclusions in the TRE. In 89% of cases, the CA1 tau rating was greater than or equal to that in CA2. In 25%, CA2 was devoid of tau inclusions. Only 4% displayed a higher tau score in CA2 than in the TRE, EC, and CA1. The perforant path also displayed early tau changes. APOE genotyping was available for 199/325 individuals. Of these, 44% had an ɛ4 allele that placed them at greater risk for developing later NFT stages and, therefore, clinical AD. Conclusions: Our new findings call into question the PART hypothesis and are consistent with the idea that our cases represent prodromal AD.

Authors: Rajamaki Blair , Braithwaite Billy , Hartikainen Sirpa , Tolppanen Anna-Maija
Published: September 2024

Background: Multimorbidity is common in older adults and complicates diagnosing and care for this population. Objective: We investigated co-occurrence patterns (clustering) of medical conditions in persons with Alzheimer’s disease (AD) and their matched controls. Methods: The register-based Medication use and Alzheimer’s disease study (MEDALZ) includes 70,718 community-dwelling persons with incident AD diagnosed during 2005-2011 in Finland and a matched comparison cohort. Latent Dirichlet Allocation was used to cluster the comorbidities (ICD-10 diagnosis codes). Modeling was performed separately for AD and control cohorts. We experimented with different numbers of clusters (also known as topics in the field of Natural Language Processing) ranging from five to 20. Results: In both cohorts, 17 of the 20 most frequent diagnoses were the same. Based on a qualitative assessment by medical experts, the cluster patterns were not affected by the number of clusters, but the best interpretability was observed in the 10-cluster model. Quantitative assessment of the optimal number of clusters by log-likelihood estimate did not imply a specific optimal number of clusters. Multidimensional scaling visualized the variability in cluster size and (dis)similarity between the clusters with more overlapping of clusters and variation in group size seen in the AD cohort. Conclusions: Early signs and symptoms of AD were more commonly clustered together in the AD cohort than in the comparison cohort. This study experimented with using natural language processing techniques for clustering patterns from an epidemiological study. From the computed clusters, it was possible to qualitatively identify multimorbidity that differentiates AD cases and controls.
On the distribution of rally length in professional tennis matches
Authors: Lisi Francesco , Grigoletto Matteo , Briglia Mirko Gabriel
Published: September 2024

In the literature, information on the rally length distribution is quite incomplete, fragmented and non-homogeneous. In this paper we fill the gap deeply analyzing the distribution of rally length in professional tennis matches in the following directions: i) we provide the empirical distribution of the rally length, not only for some categories, but for each single length; ii) we consider different distributions for men and women and for different surfaces; iii) we find the statistical distribution best fitting the data for each surface; iv) we show how the rally distribution depends on some variables, such as the probabilities of winning a point at serve and players’ heights; v) previous points are based on a much larger sample size than other works leading to very reliable results. Our analyses point out that the best distribution for rally length is a zero-one-modified Geometric distribution, whose parameters are functions of the probabilities of winning a point at serve and of the players’ heights. Results suggest that the the players’ heights is the most impacting variable on the rally length distribution.

Authors: Abiramalatha T. , Govindaraju G. , Rajaiah B. , Chandrasekar P. , Srinivas U. , Ramakrishnan S.
Published: September 2024

BACKGROUND: There is no objective criteria to wean CPAP in preterm neonates. We aimed to assess the accuracy of ‘saturation trends’ to predict successful CPAP discontinuation. METHODS: We included very preterm neonates who required CPAP. Index tests were ‘saturation trends’. Outcome was successful CPAP discontinuation, defined as baby stable in room air for 72 h. RESULTS: We had 120 neonates with mean±SD gestation 28.6±1.8 weeks. 96 (80%) neonates had successful discontinuation and 24 (20%) failed. Neonates with successful discontinuation had significantly greater ‘saturation trends’ during 24 h before discontinuing CPAP compared to those who failed [64.3 (48.1–83.7) vs. 47.3 (23.0–65.0), p = 0.001]. Saturations > 95% while on CPAP with 21% FiO2 for > 60% time had 63% sensitivity and 70% specificity to predict successful CPAP discontinuation. CONCLUSION: ‘Saturation trends’ is a readily available objective parameter that can be used to guide weaning CPAP in preterm neonates.
Revealing the unseen: The 21st ICLS statistical standards on the informal economy
Authors: Frosch Michael
Published: September 2024

Informality is widespread globally, with many workers and enterprises lacking formal arrangements. Effective statistics on the informal economy are essential for policy development, improving working conditions, and promoting decent work. Over the past 30 years, the establishment of statistical standards on informality has helped countries better measure and understand the informal sector and informal employment. Recent revisions to these standards, driven by evolving statistical labour standards and growing national experience, have led to a new resolution on informal economy statistics. Adopted at the 21st ICLS in 2023, this resolution offers a comprehensive framework for defining and measuring informality. It introduces concepts such as informal productive activities, the informal economy, the informal market economy, and informal work, setting the structure and boundaries for informality statistics. By integrating the 19th ICLS resolution on work, employment, and labour underutilization and the 20th ICLS resolution on work relationships, including ICSE-18, the new standards align with previous resolutions, promoting coherence in labour statistics. The resolution includes improved definitions of the formal and informal sectors, household own-use production and community sector, and formal and informal employment, enhancing data quality and harmonization across countries. Overall, the 21st ICLS resolution significantly enhance countries’ capacity to produce harmonized, policy-relevant statistics on the informal economy, aiding efforts to formalize it.

Authors: Zhang Xian , Yang Xia , Li Yanhong
Published: September 2024

BACKGROUND:

Bronchopulmonary dysplasia (BPD) ranks among preterm infants’ most common and severe respiratory diseases. Lung ultrasound scores (LUS) play a vital role in predicting early BPD and guiding treatment and intervention strategies for affected patients.

OBJECTIVE:

Performed a meta-analysis to assess the diagnostic LUS for newborns with BPD.

METHODS:

Online electronic databases such as MEDLINE, CINAHL, the Cochrane Library, and Web of Science were used to retrieve relevant research until May 2023. A total of 117 literatures were collected, and ten eligible articles were selected for meta-analysis.

RESULTS:

Meta-analysis was performed on 10 studies (1274 neonates). LUS at 7 days after birth (7 days of life, DOL 7) showed good diagnostic accuracy for any type of BPD, moderate and severe BPD. DOL 7 was more accurate in predicting all types of BPD (AUC [Formula: see text] 0.87, sensitivity [Formula: see text] 0.75, specificity [Formula: see text] 0.83) than moderate and severe BPD (AUC [Formula: see text] 0.80, sensitivity [Formula: see text] 0.69, specificity [Formula: see text] 0.79). There was no statistical significance between DOL 7 and DOL 14 in their accuracy for predicting all types of BPD (difference in AUC [Formula: see text] 0.04, [Formula: see text] 0.068). There was no notable distinction between DOL 7 and DOL 14 in their accuracy for predicting moderate and severe BPD (difference in AUC [Formula: see text] [Formula: see text]0.04, [Formula: see text] 0.104).

CONCLUSIONS:

The diagnostic efficacy of LUS on DOL 7 in predicting the occurrence of all types of BDP and moderate-severe BPD is determined. This will facilitate rapid and accurate detection and timely treatment, thereby reducing the risk of neonatal mortality and sequelae.

Meta-analysis of the effects of bundle interventions on ICU-acquired weakness intervention
Authors: Zhou Yan , Liu Yubao , Han Yutong , Yan Hongxia
Published: September 2024

BACKGROUND:

Intensive care unit acquired weakness (ICU-AW) is a secondary neuromuscular complication in critically ill patients, characterized by profound weakness in all four limbs. Studies have shown that bundles of care are nursing strategies that combine a series of evidence-based interventions, which collectively optimize patients’ clinical outcomes compared to individual interventions.

OBJECTIVE:

This study aims to conduct a meta-analysis of the effects of bundle interventions on ICU-AW deeply exploring the characteristics of bundle interventions, patient outcomes related to ICU-AW, and primarily investigating the effects of bundle interventions on ICU-AW. The main focus is to explore the clinical value of bundle interventions in treatment of ICU-acquired weakness in patients.

METHODS:

Computer and manual searches were conducted using keywords to retrieve relevant studies on the effects of bundle interventions on ICU-AW from databases such as PubMed, Web of Science, Cochrane Library and EMbase. The search period ranged from database inception to the present. The control group received standard ICU care, including basic nursing, while the intervention group received bundle nursing interventions.

RESULTS:

A total of 10 randomized controlled trials (RCTs) involving 1545 participants (790 in the intervention group and 755 in the control group) were included. Meta-analysis results showed that the intervention group had significantly higher muscle strength (MD [Formula: see text] 7.41, 95% CI: 6.65–8.16, [Formula: see text] 0.00001) and daily living ability (MD [Formula: see text] 34.01, 95% CI: 32.54–35.48, [Formula: see text] 0.00001) than the control group. Additionally, the incidence of ICU-AW (OR [Formula: see text] 0.39, 95% CI: 0.26–0.59, [Formula: see text] 0.00001), mechanical ventilation time (MD [Formula: see text]3.71, 95% CI: [Formula: see text]3.58[Formula: see text] [Formula: see text]2.76, [Formula: see text] 0.0001), and ICU length of stay (MD [Formula: see text]2.73, 95% CI: [Formula: see text]3.14[Formula: see text] [Formula: see text]2.31, [Formula: see text] 0.00001) were significantly lower in the intervention group than in the control group.

CONCLUSION:

ICU-AW has a severe negative impact on the recovery and functional restoration of ICU patients, increasing the treatment complexity for healthcare providers and the mortality and disability rates for patients. The bundled care approach may help reduce the incidence of ICU-AW, promote the restoration of daily activity function, enhance muscle strength, and reduce ICU stay and mechanical ventilation time for ICU patients. However, the long-term effects of bundle interventions still require further in-depth research.
BADIUZZAMAN SAID NURSI'S PERSPECTIVE ON THE NEO-TASAWWUF ISSUE OF RISALE-I NUR IN URBAN MUSLIM SOCIETY
Authors: Prayogo Tonny Ilham , Yusron Saidil , Saleh Sujiat Zubaidi , Mulyana Agus , Muhajir Muhammad Arif
Published: September 2024

Tasawwuf is a part of the study that can explore mysticism in life to get nearer to God. The modern era has disrupted the essence of the role of religion and metaphysics to be something more material and substantial. As a consequence, there is a development of Islam with socio-moral reconstruction of urban society which is called neo-Sufism. The aim of this research is to see how Sa'id Nursi tried with his 'Aql (intellect) and Qalb (heart) to comprehend the al-Qur'an in order for human beings to reach the haqiqi (ultimate) truth. The type of this research is literature research (library research). In this regard, it is more focused on studying, analyzing, researching, and understanding the renewal of Sufism in the book of Kulliyyat Risale-I Nur. A thematic approach is also employed in interpreting Sa'id Nursi's Sufism. The finding in this study is that Said Nursi had provide neo-Sufism in tasawwuf is by making nature as a mediator between man and God by including an element of fikr between dzikr and shukr, where the other Sufis only use dzikr and shukr without fikr, for achieving makrifatullah. Also, it provides a reformation of Sa'id Nursi's tasawwuf in relation to the contextual-conditional factors and the spiritual aridity of twentieth-century urban Moslem society. Therefore, this neo-Tasawwuf could potentially serve a more positive functional role in contemporary society in all aspects.

Published: September 2024

Loading and unloading works are an integral part of the construction process. Cranes of various types were mostly use to perform these works.
To ensure trouble-free operation and increase the reliability of cranes, when calculating structures and components of their working equipment, it is important to take into account dynamic loads, which are several times higher than static loads. Elements of dynamic loads in the crane suspension are its elastic components (flexible traction bodies) - ropes.
The process of lifting a load from a rigid base and picking it up is considered, which divided into three stages: the first is the selection of clearances and the tension of the ropes; the second is the pre-opening stage of lifting the load; the third is the post-detachment stage of lifting the load.
For each stage, the initial conditions accepted, the differential equations of the movement of loads compiled, their solution given taking into account many factors, and expressions derived for determining the forces in the load suspension. At the first stage, the duration of the gap selection (tension of the ropes) is determined, at the second stage, the speed of separation of the load from the base is determined, at the third stage, the maximum force in the elastic element determined.
The method of determining the forces in the suspension of the load, the duration of the selection of clearances (tension of the ropes), the speed of separation of the load from the base, and the maximum force in the elastic element presented in the work allows you to significantly simplify the solution of complex equations, to determine simple expressions and to determine them with sufficient accuracy for practical calculations values.

Published: September 2024

In quantum physics, the choice of basis is crucial for formulation. The generalization of the Pauli matrices via Kronecker product, called Kronecker-Pauli matrices,  is typically restricted to  for \(2^n\) dimensional systems. This paper explores extending this generalization to \(N\)-dimensional systems, where \(N\) is a prime integer, in order to construct \(N\times N\)-Kronecker-Pauli matrices. We begin by examining the specific cases of \(3\times 3\) and \(5\times 5\) Kronecker-Pauli matrices, with the goal of the purpose constructing a set of \(N\times N\)-Kronecker-Pauli matrices for any prime integer \(N\).
Geopolitical Risk and Emerging Markets Sovereign Risk Premia
Authors: Gamboa-Estrada Fredy , Romero José Vicente
Published: September 2024

This study examines the determinants of sovereign risk, focusing on the impact of geopolitical risk in emerging market economies (EMEs) sovereign risk metrics. Using local projection techniques, we evaluate the effects of geopolitical risk on credit default swaps (CDS) and EMBI indices in EMEs, including the recent war between Ukraine and Russia. Our findings highlight the significance of considering geopolitical risk when analyzing risk premiums for emerging markets. Notably, we find that the impact of geopolitical risk shocks on CDS is higher than the effect on EMBI spread dynamics. Furthermore, using recursive estimations, we show that the effect of geopolitical risk on sovereign CDS and EMBI spreads has been relatively stable. On the other hand, we find an important degree of heterogeneity across countries by analyzing evidence from individual countries. Some countries in our sample seem statistically unaffected by geopolitical risk, particularly when examining EMBI dynamics.

Authors: Barus Diana Alemin , Kevin Nainggolan
Published: September 2024

The development of efficient and environmentally friendly clean water production systems is becoming increasingly important. This study focuses on an innovative evaporator for a Solar Steam Generator (SSG) system designed to produce clean water using accessible materials. The SSG evaporator is constructed from cellulose bonded with Polyvinyl Alcohol (PVA) and incorporates a freeze-drying method to enhance porosity, which improves water delivery within the SSG system. To further boost the efficiency of the evaporator, activated carbon (AC) is added due to its effective absorption of visible to infrared radiation. Evaporation rate testing demonstrates that the addition of 3 wt% AC yields an evaporation rate of 1.39 kg/m²/h and an efficiency of 58.56%. Fourier-transform infrared (FTIR) spectroscopy was employed to analyze changes in the sample after AC addition and to examine infrared absorption characteristics.

Published: September 2024

This study investigates the viscosity characteristics of Renewable Energy Fuel derived from plastic waste, specifically Polypropylene (PP) and High-Density Polyethylene (HDPE). The plastics were subjected to pyrolysis using a plastic waste conversion technology machine at temperatures of 250°C to 400°C. Compared to diesel, the average viscosity of pyrolyzed PP oil is approximately 4.25 cSt, while for pyrolyzed HDPE oil, it is about 3.3725 cSt. Compared to gasoline, the average viscosity values for the oils are 0.603 cSt for PP and 0.5965 cSt for HDPE. These results indicate that both oils have viscosities similar to petrol, suggesting that PP and HDPE plastics can produce fuels with comparable fluid properties. However, further evaluation of other factors like yield, chemical composition, and combustion performance is necessary to determine which plastic provides the overall best characteristics for renewable energy fuel.

Authors: Sahrinah Erna Frida , Sahrinah
Published: September 2024

LDPE thermoplastics have been made with rice husk ash nanosilica filler, which is synthesized using the coprecipitation method. The nanosynthesis of rice husk ash silica was carried out with HCl 2M and NaOH 2.5M solvents with a ratio of 1:3. The synthesized nanosilica was then characterized using XRD and obtained an average size of 23.09 nm. Based on the results of XRF characterization, it is known that there is 92.99% SiO2 and the most abundant element, namely Si, 43.47%. The composition of each LDPE/nanosilica rice husk silica was varied (100/0, 98/2, 96/4, 94/6, and 92/8 % by weight), and mechanical properties in the form of tensile strength, elongation at break, and modulus of elasticity were tested using ASTM D638 standard. The results of the mechanical test were obtained with the optimum tensile strength value in the composition (96/4% by weight) of 10.53 MPa, the optimal elongation value at the break in the composition (100/0% by weight) of 201.5%, and the optimum elastic modulus value in the composition (96/4% by weight) of 226.57 MPa. The addition of RICE HUSK SILICA nanosilica as a filler is proven to improve the mechanical properties of LDPE thermoplastic in terms of tensile strength and modulus of elasticity compared to LDPE without filler material (100/0% by weight).

A jegybankok által alkalmazott eszközök az adott ország gazdasági, piaci, intézményi adottságaihoz, monetáris politikai szabályrendszeréhez, szakmai „hagyományaihoz” és törvényi felhatalmazásához illeszkednek. Az eszköztárakat a 2008-as pénzügyi válság előtt az „általános hatókörű” eszközök uralták, a célzott jegybanki programok a válságkezelés részeként „érkeztek meg” ebbe a keretrendszerbe. Jelen tanulmányban definiálásra kerül az általános és a célzott jegybanki eszköz fogalma, rámutatva, hogy a célzott programok eredetileg a monetáris transzmisszió hatékonyabbá tételét célozták, de bizonyos iparágak eltérő kezelésére is lehetőséget nyújthatnak. A célzott eszközök kínálta lehetőségek mellett a kapcsolódó kihívásokat is ismertetem, majd a célzott programok négy rendszertani pillérét (hozzáadott érték, célmeghatározás, legitimáció és intézményi keretek, illetve operatív megvalósíthatóság) ismertetem. Dolgozatom a nemzetközi és hazai gyakorlati példák bemutatásával, illetve a jövőbeli várható trendek és kutatási irányok felvázolásával zárul.

Planning in the use of components in a power system needs to be done correctly. The planning will affect the optimization of the system in distributing power. Suboptimal power distribution will have an impact on the continuity of the power being distributed. The analysis that will be carried out is a power flow analysis. This research was taken using data from ULP Kota Baru Penyulang Palem, the location of this research is located in the distribution system area of Jambi City, Jambi Province, with the connection center at Penyulang Palem which is located in Kota Baru District, Jambi City, Jambi Province. . KVA is used to measure the total power in an electrical system. Total power includes active power and reactive power, so KVA provides a more complete picture of the power requirements of an electrical system. In the KVA measurement, it is assumed that all loads connected on a single line are 85%, 90%, 95%. That the greater the assumed load of the transformer and the farther away from the source, the greater the voltage drop / the smaller the voltage The greater the resistance the smaller the voltage drop, if the smaller the resistance then the drop will be larger. The wider the cross-section, the smaller the strain drop. The highest measurement of all loads is 3918 kv at the base of the source located near the bus in JB1100 assuming all loads of 95%.

Leadership is an indispensable element in the process of initiating and maintaining the development of a quality culture in a construction organization. Leadership can create an appropriate environment to provide maximum comfort to group members to improve performance and productivity. Strong leadership from top management is essential in developing and maintaining a quality-based culture in an organization that acts as a catalyst for the implementation of Total Quality Management (TQM). This paper aims to discuss the conceptual framework of how leadership can help change the quality culture in an organization. The discussion was carried out using a literature review of the concepts of Quality, Culture and Leadership and Organizational Culture. Analysis of the study was carried out on cultural changes and the role of leadership in developing a quality culture. The results of the study show that organizations need to shift from their current culture to a TQM culture that focuses on quality as the main strategy. Furthermore, thirteen important cultural dimensions can be identified that contribute to the successful implementation of TQM, where most of these dimensions are related to leadership. The proposed Quality Culture Development and Leadership Framework in Construction in Indonesia can be a model for developing a quality culture in construction organizations through effective leadership, so that construction organizations can use it creatively to minimize inconsistencies and conflicts.

Construction in Indonesia is one of the government's top priorities in an effort to improve the welfare of the society. Construction planning must be carefully planned in order to achieve efficiency in project implementation, in terms of time and cost. A construction project requires planning and controlling material inventory. The purpose of material planning and control is so that construction projects can run smoothly, effectively and efficiently. Material planning and control can be analyzed using the material requirements planning (MRP) method. In this study, using economic order quantity (EOQ) and period order quantity (POQ) techniques. Cost budget design data, s-curves, work unit price analysis, and work progress reports are the data components to be processed. The results showed the cost of procurement of materials needed with the EOQ technique, namely: purchase cost of IDR 8,466,623,718.49, ordering cost of IDR 1,598,050.00, and storage cost of IDR 8,942,979.62. The total cost required is IDR 8,477,164,748.11. Furthermore, for the POQ technique, namely: purchase cost of IDR 8,466,623,718.49, ordering cost of IDR 1,598,050.00 and storage cost of IDR 9,674,554.05. The total cost required is IDR 8,477,896,322.53 Comparison of the costs required from the EOQ and POQ techniques can be concluded that Material Requirement Planning (MRP) using the Economic Order Quality (EOQ) technique is less costly than the Period Order Quantity (POQ) technique. Material procurement using Economic Order Quality (EOQ) is more effective. This is because the EOQ technique requires less costly / economic procurement compared to the POQ technique. In addition, with the application of the EOQ technique, there is a clearer material ordering schedule and the amount of material ordered is in accordance with the needs so that the material storage is not too much.

One piece of infrastructure that has an important role in a road network is a bridge. Bridges are land transportation infrastructure that is useful for continuing roads through existing obstacles such as rivers, so the collapse of a bridge will reduce or hold up traffic, which means disrupting the smooth transportation of people and goods. A bridge is a structure that crosses a river or other traffic barrier, so the collapse of the bridge will reduce or hold back traffic, which as a result will disrupt the comfort of traffic and disrupt economic relations. The purpose of a bridge inspection is to ensure that the bridge is in a safe condition for road users and also to secure the investment value of the bridge. In this thesis, we will discuss the identification of bridge condition checks which are carried out directly by conducting field surveys.
