Authors: Xu Hui , Yan Rong , Ye Chunmei , Li Jun , Ji Guo 
Published: April 2024

Abstract
Background
The full potential of competing risk modeling approaches in the context of diffuse large B-cell lymphoma (DLBCL) patients has yet to be fully harnessed. This study aims to address this gap by developing a sophisticated competing risk model specifically designed to predict specific mortality in DLBCL patients.

Methods
We extracted DLBCL patients’ data from the SEER (Surveillance, Epidemiology, and End Results) database. To identify relevant variables, we conducted a two-step screening process using univariate and multivariate Fine and Gray regression analyses. Subsequently, a nomogram was constructed based on the results. The model’s consistency index (C-index) was calculated to assess its performance. Additionally, calibration curves and receiver operator characteristic (ROC) curves were generated to validate the model’s effectiveness.

Results
This study enrolled a total of 24,402 patients. The feature selection analysis identified 13 variables that were statistically significant and therefore included in the model. The model validation results demonstrated that the area under the receiver operating characteristic (ROC) curve (AUC) for predicting 6-month, 1-year, and 3-year DLBCL-specific mortality was 0.748, 0.718, and 0.698, respectively, in the training cohort. In the validation cohort, the AUC values were 0.747, 0.721, and 0.697. The calibration curves indicated good consistency between the training and validation cohorts.

Conclusion
The most significant predictor of DLBCL-specific mortality is the age of the patient, followed by the Ann Arbor stage and the administration of chemotherapy. This predictive model has the potential to facilitate the identification of high-risk DLBCL patients by clinicians, ultimately leading to improved prognosis.

Abstract
Background
Attention Deficit/Hyperactivity Disorder (ADHD) is one of the most common disorders in school-aged children. Learning disorder (LD) is also one of the most important psychiatric disorders in children, which can often be associated with ADHD. In this study, we sought to compare self-esteem and quality of life in 8 to 12-year-old children with attention deficit/hyperactivity disorder with and without co-occurring learning disorders in order to emphasize the importance of attention and diagnosis in children with ADHD.

Method
Among the 8- to 12-year-old outpatients referred to the child and adolescent psychiatry clinic of Omid Babol Clinic, 120 children aged 8 to 12 years with attention deficit/hyperactivity disorder whose disease was diagnosed by a child and adolescent psychiatry subspecialist. Among the tools used to collect information was the Colorado Learning Difficulties Questionnaire by Wilcott et al. (CLDQ), five-scale self-esteem test of Pepe et al. (1989) for children and quality-of-life questionnaire for 8–12-year-old children (PedsQL).

Results
This study investigated self-esteem and quality of life in children with ADHD (n = 120, 51.7% boys). Children with ADHD and learning disabilities reported significantly lower self-esteem and quality of life compared to those with ADHD alone.

Conclusion
Considering the relatively high probability of co-occurrence of ADHD and learning disorders, if one of them is diagnosed in a child, it is possible to look for other disorders in the child in order to avoid the more severe negative effects that this co-occurrence can have on the child by diagnosing it as soon as possible.

AbstractThe use of constructed wetlands (CWs) is one of the best options to treat wastewater. In CWs, microorganisms play a major role in the degradation of organic pollutants but the concentration of nutrients, surfactant, and aeration (NSA) in oil-contaminated water is one of the factors that affect the persistence and metabolic functioning of hydrocarbon-degrading microorganisms. In the present investigation, the influence of the addition of NSA on the persistence of the augmented bacteria, copy of (alkane hydroxylase gene) alkB gene, and its expression level in the water, soil, and plants of CWs were evaluated. The CWs mesocosms were developed by the vegetation of Typha latifolia and Cyperus laevigatus and inoculated with the bacterial consortium (Pseudomonas putida TYRI39, Acinetobacter junii TYRH47, Acinetobacter sp. CYRH17, Pseudomonas sp. CYSI27, and Pseudomonas sp. TYRH42). The mesocosms were provided with nutrients (20 mg l− 1 N, 2.6 mg l− 1 P, and 16.4 mg l− 1 K) in liquid form, surfactant Tween-20 (0.2%, v/v) in liquid form, and aeration (≥ 7.0 ± 1 mg l− 1 DO) using aeration pump. The addition of NSA in CWs enhanced the persistence and metabolic functioning of the inoculated bacteria in the water, rhizospheric soil, and plants. The maximum hydrocarbon removal (97%) was observed in the water treated by CWs having C. laevigatus, bacteria, and NSA, and it is correlated with the copy numbers of alkB and its expression level. The application of NSA in CWs not only improved bacterial persistence and catabolic gene expression but also increased plant development and hydrocarbon removal.
Forecasting relative returns for S&P 500 stocks using machine learning
Authors: Htun Htet Htet , Biehl Michael , Petkov Nicolai 
Published: April 2024

AbstractForecasting changes in stock prices is extremely challenging given that numerous factors cause these prices to fluctuate. The random walk hypothesis and efficient market hypothesis essentially state that it is not possible to systematically, reliably predict future stock prices or forecast changes in the stock market overall. Nonetheless, machine learning (ML) techniques that use historical data have been applied to make such predictions. Previous studies focused on a small number of stocks and claimed success with limited statistical confidence. In this study, we construct feature vectors composed of multiple previous relative returns and apply the random forest (RF), support vector machine (SVM), and long short-term memory (LSTM) ML methods as classifiers to predict whether a stock can return 2% more than its index in the following 10 days. We apply this approach to all S&P 500 companies for the period 2017–2022. We assess performance using accuracy, precision, and recall and compare our results with a random choice strategy. We observe that the LSTM classifier outperforms RF and SVM, and the data-driven ML methods outperform the random choice classifier (p = 8.46e−17 for accuracy of LSTM). Thus, we demonstrate that the probability that the random walk and efficient market hypotheses hold in the considered context is negligibly small.
Hepatic artery stenosis following adult liver transplantation: evaluation of different endovascular treatment approaches
Authors: Desai Sagar V. , Natarajan Balasubramani , Khanna Vinit , Brady Paul 
Published: April 2024

Abstract
Purpose
To evaluate the efficacy and safety of hepatic artery interventions (HAI) versus extra-hepatic arterial interventions (EHAI) when managing clinically significant hepatic artery stenosis (HAS) after adult orthotopic liver transplantation.

Materials and methods
A single-center retrospective cohort analysis was conducted on liver transplant patients who underwent intervention for clinically significant HAS from September 2012 to September 2021. The HAI treatment arm included hepatic artery angioplasty and/or stent placement while the EHAI treatment arm comprised of non-hepatic visceral artery embolization. Primary outcomes included peri-procedural complications and 1-year liver-related deaths. Secondary outcomes included biliary ischemic events, longitudinal trends in liver enzymes and ultrasound parameters pre-and post-intervention.

Results
The HAI arm included 21 procedures in 18 patients and the EHAI arm included 27 procedures in 22 patients. There were increased 1-year liver-related deaths (10% [2/21] vs 0% [0/27], p = 0.10) and complications (29% [6/21] vs 4% [1/27], p = 0.015) in the HAI group compared to the EHAI group. Both HAI and EHAI groups exhibited similar improvements in transaminitis including changes of ALT (-72 U/L vs -112.5 U/L, p = 0.60) and AST (-58 U/L vs -48 U/L, p = 0.56) at 1-month post-procedure. Both treatment arms demonstrated increases in post-procedural peak systolic velocity of the hepatic artery distal to the stenosis, while the HAI group also showed significant improvement in resistive indices following the intervention.

Conclusion
Direct hepatic artery interventions remain the definitive treatment for clinically significant hepatic artery stenosis; however, non-hepatic visceral artery embolization can be considered a safe alternative intervention in cases of unfavorable hepatic anatomy.

Abstract

Context
Detecting patients with surgically curable aldosterone-producing adenoma (APA) among hypertensive individuals is clinically pivotal. Liquid chromatography–tandem mass spectrometry (LC-MS/MS) is the ideal method of measuring plasma aldosterone concentration (PAC) because of the inaccuracy of conventional chemiluminescent enzyme immunoassay (CLEIA). However, LC-MS/MS is expensive and requires expertise. We have developed a novel noncompetitive CLEIA (NC-CLEIA) for measuring PAC in 30 minutes.

Objective
This work aimed to validate NC-CLEIA PAC measurements by comparing them with LC-MS/MS measurements and determining screening cutoffs for both measurements detecting APA.

Methods
We retrospectively measured PAC using LC-MS/MS and NC-CLEIA in 133 patients with APA, 100 with bilateral hyperaldosteronism, and 111 with essential hypertension to explore the accuracy of NC-CLEIA PAC measurements by comparing with LC-MS/MS measurements and determined the cutoffs for detecting APA.

Results
Passing-Bablok analysis revealed that the values by NC-CLEIA (the regression slope, intercept, and correlation coefficient were 0.962, −0.043, and 0.994, respectively) were significantly correlated and equivalent to those by LC-MS/MS. Bland-Altman plot analysis of NC-CLEIA and LC-MS/MS also demonstrated smaller systemic errors (a bias of −0.348 ng/dL with limits of agreement of −4.390 and 3.694 within a 95% CI) in NC-CLEIA than LC-MS/MS. The receiver operating characteristic analysis demonstrated that cutoff values for aldosterone/renin activity ratio obtained by LC-MS/MS and NC-CLEIA were 31.2 and 31.5 (ng/dL per ng/mL/hour), with a sensitivity of 91.0% and 90.2% and specificity of 75.4% and 76.8%, respectively, to differentiate APA from non-APA.

Conclusion
This newly developed NC-CLEIA for measuring PAC could serve as a clinically reliable alternative to LC-MS/MS.

Authors: Bin Karnoto Suparjito 
Published: April 2024

This study aims to assess the government policy implementation in assisting communities affected by the COVID-19 pandemic through the Village Fund Direct Cash Assistance (BLT DD). This research is important to assess the success of policies that have been implemented by the government in the field. Data were collected from village funds realized in the Central Java Province in 2020. The regional government's financial performance assessment was analyzed using secondary data. The validity and reliability analysis of the questionnaire data were also used to measure the performance of BLT DD management. The results of secondary data processing showed that the performance of BLT DD management is running effectively and efficiently. Meanwhile, the primary data processing results from the questionnaire indicated that the management has been going well, starting from the planning, implementation, responsibility, professionalism, and accountability stages of the village government apparatus as the spearhead of BLT DD management. The implication of the study is the BLT DD distribution through a transfer to the bank account of each beneficiary.

Published: April 2024

The purpose of this study is to determine the long-term and short-term relationship between inflation, interest rates, exchange rates, and economic growth to the demand for money in Indonesia. The method used in this study is Autoregressive Distributed Lag (ARDL). The Data used are money demand, inflation, interest rates, exchange rates, GDP in Indonesia for the period 2015-2021. The results of this study are inflation has a positive relationship and significantly affects the demand for money, interest rates have a negative relationship and does not affect significantly, the exchange rate has a positive relationship, while GDP has a positive relationship in the short term, but in the long term has a negative relationship and does not affect significantly. Policymakers should develop and implement comprehensive long-term economic plans that prioritize sustainable growth. This may include initiatives to diversify the economy, enhance productivity, improve infrastructure, and promote investments to foster a stable economic environment that minimizes adverse effects on the demand for money in the long run. This research can help monetary authorities determine appropriate policies to maintain economic stability, such as collaborating with the government in overcoming market failures with the aim of achieving price stability.

New multiplicity results in prescribing Q-curvature on standard spheres
Authors: Ben Ayed Mohamed , El Mehdi Khalil 
Published: April 2024

Abstract
In this paper, we study the problem of prescribing Q-Curvature on higher dimensional standard spheres. The problem consists in finding the right assumptions on a function K so that it is the Q-Curvature of a metric conformal to the standard one on the sphere. Using some pinching condition, we track the change in topology that occurs when crossing a critical level (or a virtually critical level if it is a critical point at infinity) and then compute a certain Euler-Poincaré index which allows us to prove the existence of many solutions. The locations of the levels sets of these solutions are determined in a very precise manner. These type of multiplicity results are new and are proved without any assumption of symmetry or periodicity on the function K.
Fiscal Prospects for Italy
Authors: Bordignon Massimo , Turati Gilberto 
Published: April 2024

Abstract
After the pandemic peak, public debt over GDP in Italy has fallen sharply thanks to high real and nominal economic growth; a few institutional changes have further reduced concerns about its medium-term sustainability. Yet, the debt ratio is still too high and needs to be reduced. The gradual adjustment path forecasted by the new Eu fiscal rules seems broadly able to reach this objective without imposing too harsh policies that might turn out to be economically and politically counter-productive. Still, without a serious reform of the Eu and the Eu budget, there remains the problem of how Italy and the other European countries will finance the new spending priorities dictated by the green deal and the mutated geo-political situation. And in the longer run, the demographic shock remains the most serious concern for public debt sustainability.
Interaction and conventionalized expressions create the contexts for bleaching and constructional expansion: the case of GRAB
Authors: Bybee Joan , Moder Carol Lynn 
Published: April 2024

Abstract
A corpus study of 100+ years of usage of the verb GRAB in American English contributes to the understanding of the way bleaching takes place. The meaning of GRAB as ‘take or seize suddenly or eagerly’ is firmly established in usage from 1910 through 1980, but in the 1990’s many instances of a bleached sense of ‘take or get easily or casually’ begin to occur. The proposed hypothesis that bleaching results from hyperbolic uses is supported by the finding that bleaching occurs within three common contexts: narrative sequences of GRAB followed by another verb; contexts expanding on grab a bite (to eat); and GRAB plus human object, which changes from a sense of ‘take custody of’ to simply ‘capture the attention of’. In addition, the interactional context of requests and offers (often of food and drink) hastens the bleaching of GRAB while also contributing the resulting interpretation of GRAB as ‘get or take easily or casually’. The same conversational actions constitute the contexts in which GRAB is established in the ditransitive construction, as well as the contexts in which it takes on the social meaning of getting or taking in a quick, easy and casual manner.
What Research through Art can bring to CSCW: exploring ambiguous futures of work
Authors: Dunn Kellie , Shklovski Irina , Bjørn Pernille 
Published: April 2024

Abstract
As work is shifting and changing, we, CSCW researchers, must consider our role in creating work futures, and what experiences we want to produce through technology design. What qualities are important to consider about the human experience when designing work technologies for the future? Exploring the potentials of artistic practices for epistemological inquiry, we demonstrate Research through Art as a novel futuring approach for CSCW research, leveraging the power of artistic practice for exploring questions of human experience. We engaged with young artists who created art pieces that manifested their hopes, intuitions, and anxieties on the future of work. Our analytical inquiry of these artistic practices allowed us to explore what different futures might be imaginable and what might these futures feel like. We find that futuring entails engaging with ambiguities, which can be a productive resource for design. We identified the ambiguities of time, purpose, body, identity, and agency as foundational for the imaginaries produced by the artists. By intersecting the ambiguities, we can begin to systematically frame novel design questions for CSCW technologies of the future by conceptualizing these ambiguities as multifinalities – single points from which many possibilities emerge.

Published: April 2024

Abstract
The aim of this study was to develop a stable palm carotene-based emulsion using the rice protein isolate-flaxseed gum complex (RPI-FG) with different ratios (3:1, 5:1, 7:1, 9:1, 11:1). RPI achieved highest solubility at pH 12. Meanwhile, RPI-FG complex shows low turbidity value from pH 6 to 12 for all ratios. Emulsion with ratio 7:1 exhibited 33 % droplet size increment throughout 7 days storage and evenly distributed based on the microstructure images. For creaming index (CI), all emulsion shows 0 % separation on day zero except emulsion with ratio 11:1 (1.90 %) and lowest CI on day 7 was 9.05 % in ratio 3:1. Furthermore, emulsion activity index and emulsion stability index of the emulsions decreased significantly with the reduced of FG in the formulation. These results suggested that carotene-based emulsion fabricated using RPI-FG complex with ratio of 7:1 exhibited the highest emulsion stability and could be further applied in aqueous food systems.
