Graphene oxide modified polypropylene filter membrane for enhanced a filter of face masks
Authors: Asriza R O , Puspita I , Yulia  
Published: December 2024

Abstract
In this paper, polypropylene/graphene oxide composites were prepared through a melt process method. Polypropylene was melted at 180 °C and then added with graphene oxide. When graphene oxide was added, graphene oxide was encapsulated on the polypropylene surface through hydrogen bonds. This event shifted the degradation temperature to 169 °C. This membrane has a pore size of 0.17 μm. This research provides a new and simple material to prepare a mask filter membrane that is effective in absorbing particulate matter and is environmentally friendly.

Authors: Reniati R , Faisal F 
Published: December 2024

Abstract
Micro, Small, and Medium Enterprises (MSMEs) are vital to Indonesia’s economy, contributing significantly to income generation across sectors. These enterprises, often small or micro-scale, are owned and managed by entities meeting specific size criteria. This study in Bangka Belitung Province aims to assess Green SME adoption among MSMEs and propose policies for sustainable practices. Using quantitative methods, the study collected numerical data to analyze relationships between variables. Research instruments were rigorously validated, with validity coefficients exceeding 0.300 and reliability surpassing 0.600. Through purposive sampling, 50 actively engaged MSMEs were selected, with data collected via questionnaires, observations, and documentation. Structural Equation Modeling (SEM), specifically Partial Least Squares Path Modeling (PLSPM), was used for its ability to handle complex relationships. Findings show that Green Entrepreneurship and Innovation significantly enhance environmental sustainability in MSMEs, promoting carbon-neutral activities and resource efficiency. Sustainable Business practices under the Green SMEs framework reduce operational costs and prioritize environmental conservation, shaping a model integrating environmental principles into business strategies. Policy recommendations include incentivizing green practices, training for sustainable methodologies, and supporting green innovation. These steps are crucial for enhancing MSME resilience and sustainability while advancing environmental goals in Bangka Belitung and beyond.

Abstract
At present, the culture-based bacterial detection approach is time-consuming and necessitates a thorough sample preparation process. Surface-enhanced Raman spectroscopy (SERS) and surface plasmon-enhanced auto-fluorescence spectroscopy (SPEAS) enable the label-free identification and quantification of bacterial pathogens at low concentrations. The identification is done using its unique auto-fluorescence and Raman signatures utilising highly anisotropic three-dimensional nanostructures of silver nano dendrites (Ag-NDs). The SERS data facilitates qualitative bacterial identification using the spectral features from the bacterial cell wall or its compound. The SPEAS data was utilised to gain unique auto-fluorescence spectra present on the bacterial cell wall with enhanced quantification. The enhancement of Raman and auto-fluorescence signals of Ag-NDs were first evaluated using rhodamine 6 G(R6G) as a probe molecule that exhibits a significant enhancement of 106 and limit of detection (LOD) of 10−12 M for SERS and 15-fold intensity enhancement and LOD of 10−15 M for SPEAS measurements. Further, the SERS and SPEAS measurements of bacterial pathogens, such as Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), using the Ag-NDs were recorded. The results exhibit high auto-fluorescence and Raman signal intensity for the samples up to 100 cfu/ml for both modalities. The significant photon count and distinct emission range in SPEAS measurements of bacteria enables accurate quantification. Therefore, the comprehensive investigation of plasmonic enhancement of Ag-NDs for SPEAS and SERS techniques provides complementary information about molecules to enable accurate and quick identification and quantification of pathogens.
Interlayer dislocations in multilayer and bulk MoS2
Authors: Soltero Isaac , Fal’ko Vladimir I 
Published: December 2024

Abstract
Dislocations in van der Waals materials are linear defects confined to the interfaces between consecutive stoichiometric monolayers of a bulk layered crystal. Here, we present a mesoscale model for the description of interlayer dislocations in thin films of transition metal dichalcogenides. Taking 2H-MoS2 as a representative material, we compute the dependence of the dislocation energy on the film thickness, from few-layer MoS2 to the bulk crystal, and analyse the strain field in the layers surrounding a dislocation. We also analyse the influence of strain field on the band edge profiles for electrons and holes, and conclude that the resulting energy profiles are incapable of localising charge carriers, in particular at room temperature.

Abstract

Purpose. To investigate the effect of the position and orientation of the detector and its influence on the determination of output factors (OF) for small fields for a linear accelerator (MR-linac) integrated with 1.5 T magnetic resonance following the TRS-483 formalism. Methods. OF were measured for small fields in the central axis following the recommendations of the manufacturer and at the dose maximum following the TRS-483 formalism. OF were determined using a microDiamond (MD), a Semiflex (SF) 31021 ionization chamber, Gafchromic EBT3 film and were calculated in Monaco treatment planning system (TPS). Additionally, the orientation response of SF was evaluated, placing it in parallel and perpendicular direction to the radiation beam. The values were compared taking film measurements as reference. The corrected factors,

for SF and MD, following the measured values in this work. Results. In fields smaller than 4 cm, the positioning of the SF and MD in the central axis or at the point of dose maximum affects the reading significantly with differences of up to 6% and 4%, respectively. For the data calculated in the TPS, the maximum difference of the OF between MD and TPS for fields greater than 2 cm was 0.6% and below this field size the TPS underestimates the OF up to 10.6%. The orientation (parallel or perpendicular) of the SF regarding the radiation beam has a considerable impact on the OF for fields smaller than 3 cm, showing a variation up to 10% for the field of 0.5 cm. Conclusion. This study provides valuable information on the challenges and limitations of measuring output factors in small fields. The outcomes have important implications for the practice of radiosurgery, underscoring the need for accuracy in detector placement and orientation, as well as the importance of using more advanced technologies and more robust measurement methods.
Graphical User Interface Using Tkinter
Authors: Essick John 
Published: December 2024

Abstract
Readers use Tkinter, the graphical user interface (GUI) toolkit included as part of the Python Standard Library, to equip their integer-parity-testing program with a GUI. After importing Tkinter into the program, an interactive GUI is created by populating an operating-system window with Tkinter label, entry, and button widgets, along with a frame widget to organize the GUI layout. In the process of creating this program, Python’s support of both object-oriented programming (via classes) and functional programming (via functions) is discussed and implemented. Readers carry out the procedure for creating their own custom-made function and learn how to call this function from the body of a Python program and also how to import this function when it resides in an external Python module. A Do It Yourself project explores writing a GUI-equipped program that converts values between two different temperature scales, and a Use It! example demonstrates how to execute a Python module as a stand-alone program.
Data Acquisition Using NI DAQ Device
Authors: Essick John 
Published: December 2024

Abstract
After their Chapter 6 orientation to the NI DAQ device’s capabilities via MAX, readers write Python-based data acquisition and generation programs that call functions from the NI device driver software NI-DAQmx. These programs execute analog-to-digital and digital-to-analog tasks on the NI DAQ device in order to realize several computer-based instruments, including a DC voltmeter, digital oscilloscope, DC voltage source, and hardware-timed waveform generator. The necessity for placing GUI and DAQ operations on separate execution threads, as well as the need for triggering in an oscilloscope application, are explored. A Do It Yourself project implements the DAQ device’s digital outputs to create a blinking LED array and a Use It! example demonstrates how a lowpass filter can effectively eliminate aliasing in the waveform-digitization process.
Single-Stage Alar Nostril Ring Correction Using Auricular Composite Grafts in Reconstructive Rhinoplasty
Authors: Sazgar Amir A , Sazgar Amir K , Hatami Nikou , Sazgar Mehr A 
Published: December 2024

Abstract

Background
Alar nostril ring correction in patients with multiple previous surgeries is one of the most challenging procedures in reconstructive rhinoplasty. Assessment of patient satisfaction and the technique's failure rate is essential in evaluating its effectiveness.

Objectives
In this study, we aimed to assess the outcomes of alar nostril ring correction with auricular composite grafts (ACGs) in patients with severe postrhinoplasty deformities from multiple previous surgeries.

Methods
A retrospective review of medical records from April 2016 to October 2023 was conducted. Patient demographics, surgical techniques, and functional and aesthetic outcomes were analyzed. Patient satisfaction was measured with the Obstruction and Cosmesis scores from the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS).

Results
A total of 45 cases (38 female and 7 male) ages 36.4 ± 7.64 years underwent alar nostril ring correction with ACGs from the antihelix, with an average of 2 previous rhinoplasties. Preoperative SCHNOS-O and SCHNOS-C scores were 88.44 (SD = 14.41) and 88.30 (SD = 12.44), respectively. The shape of the ACGs was similar to parabolic cylinders, with arc lengths between 15 and 21 mm and flat dimensions of 6 to 9 by 3 to 7 mm. No graft failures were observed, even in 10 patients with a history of nasal skin necrosis. Postoperative SCHNOS-O and SCHNOS-C scores after 1 year were 35.44 (SD = 21.07) and 35.85 (SD = 19.04), representing significant improvement (P &lt; 0.05).

Conclusions
ACGs from the antihelix effectively address external valve stenosis due to aggressive alar-sill junction tissue resection in reconstructive rhinoplasty, even in complex cases.

Testing Routine Activity Theory: Behavioural Pathways Linking Temperature to Crime
Authors: Thomas Christopher , Jeong Jinuk , Wolff Kevin T 
Published: December 2024

Abstract
This study examines direct observations of outdoor routine activities to investigate the pathways through which temperatures shape crime. Daily administrative records of crime, weather and outdoor activity were assembled from 2015 to 2019 in New York City. Mediation analysis (with bootstrapped standard errors) reveals that alterations in routine activities account for a statistically significant, yet modest, proportion of temperature’s relationship with homicides, shootings, assaults, larceny and public consumption violations. The comparable mediation effects across violent and nonviolent crimes support routine activity theory as an explanatory framework for understanding temperature’s impact on crime. The measures introduced here offer a novel approach for testing the theory and suggest other potential applications.

Abstract
Plasma phosphorylated-tau217 (p-tau217) has been shown to be one of the most accurate diagnostic markers for Alzheimer’s disease. No studies have compared the clinical performance of p-tau217 as assessed by the fully automated Lumipulse and single molecule array (SIMOA) AlZpath p-tau217.
The study included 392 participants, 162 with Alzheimer’s disease, 70 with other neurodegenerative diseases with CSF biomarkers and 160 healthy controls. Plasma p-tau217 levels were measured using the Lumipulse and ALZpath SIMOA assays. The ability of p-tau217 assessed by both techniques to discriminate Alzheimer’s disease from other neurodegenerative diseases and controls was investigated using receiver operating characteristic analyses.
The p-tau217 levels measured by the two techniques demonstrated a strong correlation, showing a consistent relationship with CSF p-tau181 levels. In head-to-head comparison, Lumipulse and SIMOA showed similar diagnostic accuracy for differentiating Alzheimer’s disease from other neurodegenerative diseases [area under the curve (AUC) 0.952, 95% confidence interval (CI) 0.927–0.978 versus 0.955, 95% CI 0.928–0.982, respectively] and healthy controls (AUC 0.938, 95% CI 0.910–0.966 and 0.937, 95% CI 0.907–0.967 for both assays).
This study demonstrated the high precision and diagnostic accuracy of p-tau217 for the clinical diagnosis of Alzheimer’s disease using fully automated or semi-automated techniques.
The “Great Powers” and The Formation of International Law
Authors: Heller Kevin Jon 
Published: December 2024

Abstract
The US, Russia, and China – the current “Great Powers” – often disagree over primary rules of international law, such as the scope of self-defence in response to an armed attack. Such disagreements over primary rules can often be explained in traditional realist fashion, because powerful States generally interpret international law in a manner that reflects and advances their interests. But that is not always the case. In some situations, Great Power disagreements over primary rules are driven less by realpolitik than by very different understandings of the formal sources of international law – the sources that determine what qualifies as a primary rule.
Most comparative international law scholarship has focused on how the Great Powers view primary rules, ignoring how the US, Russia, and China disagree over the formal sources of international law. This article focuses on disagreements in the latter category. After a brief introduction in Part I, Part II explains how the US, Russia, and China perceive the formal sources of internal law in abstracto – which they privilege and why, methodological inconsistencies in how they understand and apply a particular source, and so on. Part III then examines four areas of international law in which different perceptions of the formal sources have a significant effect on how the US, Russia, and China perceive the primary rules: the jus ad bellum, the jus in bello, arms control, and cyberspace. Some concluding remarks follows in Part IV.

Abstract

OBJECTIVES
Mesenteric malperfusion in acute aortic dissection remains a life-threatening complication with no standardized treatment strategy. This study aimed to describe and evaluate the outcomes of our integrated approach combining exploratory laparotomy, immediate mesenteric reperfusion, and central aortic repair.

METHODS
We retrospectively reviewed patients with acute aortic dissection with a preoperative diagnosis of mesenteric malperfusion who were treated between August 2011 and November 2022. Our surgical approach was to establish cardiopulmonary bypass, followed by exploratory laparotomy with mesenteric artery flow assessment using Doppler ultrasound and direct perfusion if needed, central aortic repair, and subsequent mesenteric artery reconstruction. The primary end-point was the 30-day operative mortality.

RESULTS
Among 217 patients with acute aortic dissection, 12 (5.5%) had mesenteric malperfusion on preoperative computed tomography. Ten patients underwent exploratory laparotomy, where Doppler ultrasonography revealed reduced mesenteric blood flow in five patients (2.3% of the total 217 patients). These patients underwent direct perfusion of the mesenteric artery via a side branch of the cardiopulmonary bypass circuit. Doppler ultrasound confirmed the restoration of mesenteric blood flow in all perfused patients. No bowel resections were required. The operative mortality in patients with mesenteric malperfusion was 20%. The causes of death were stroke (n = 1) and acute myocardial infarction (n = 1).

CONCLUSIONS
Our integrated surgical strategy combining central aortic repair with concurrent exploratory laparotomy and immediate mesenteric perfusion demonstrated technical feasibility in managing mesenteric malperfusion during aortic repair. Further prospective studies with larger cohorts are warranted to validate these findings.

Abstract

Objective
Adreno CorticoTropic Hormone (ACTH)-independent Cushing's syndrome (CS) in children is very rare but potentially fatal. In bilateral nodular hyperplasia, synchronous bilateral adrenalectomy (SBA) represents the definitive treatment to correct hypercortisolism. We aim to report the multidisciplinary management of this rare condition.

Methods
Presentation, management, and outcomes of all children with ACTH-independent CS who underwent SBA in a tertiary reference center between 1992 and 2022 were retrospectively analyzed.

Results
Ten children were included: 6 with McCune–Albright syndrome, 4 with primary pigmented nodular adrenocortical disease (3 with Carney complex). Presentation varied according to age at diagnosis. In infants (n = 7), failure to thrive with anorexia (n = 7), cushingoid facies (n = 7), arterial hypertension (n = 6), hypotonia (n = 5), hyperglycemia (n = 4), liver dysfunction (n = 4), and hypercalcemia with nephrocalcinosis (n = 4) were the main reasons for urgent hospitalization. Prepubertal children (n = 3) presented with linear growth arrest associated with obesity, cushingoid facies, and hirsutism. SBA was indicated in severe neonatal hypercortisolism, or in those that were non-responsive to medical treatment. SBA was performed by robot-assisted laparoscopy (n = 6), laparoscopy (n = 2) or laparotomy (n = 2). One post-operative complication occurred (seroma in the adrenal bed). During follow-up, (median: 4.8 years) no deaths or acute adrenal crisis occurred.

Conclusion
Pediatric CS must be referred to a pediatric center with medical and surgical expertise. Shared decision-making regarding SBA must be prompt to allow rapid cure of CS, even if it implies lifelong steroid replacement. This avoids long-term complications of hypercortisolism, particularly cognitive decline. Robot-assisted SBA is feasible and safe, even in infants when performed by an experienced robotic team.

Published: December 2024

Abstract
This review essay of Data Driven by Karen Levy explores the legal infrastructures of capital flow in trucking. Trucking sits alongside other modes of the transportation of commodities, like shipping, where networks of laws and regulations for global capital movement (public, private, domestic, transnational and international) become visible. The insightful centring of truckers in Data Driven acts as an example of sensitive and critical storytelling around capitalism, highlighting the classed, devalued and exploited labour facilitating capital flow.
Evolutionary mismatch in emotional support during childbirth: Lessons from the COVID-19 pandemic
Authors: Thayer Zaneta M , Samsonov Anna , Farewell Charlotte V , Gildner Theresa E 
Published: December 2024

Abstract

Background and Objectives
Selective pressures on human childbirth have led to the evolution of cooperative birth practices, with birth attendants playing a crucial role in providing emotional support during labor.

Methodology
We leveraged COVID-19-related healthcare disruptions to investigate the impact of the evolutionary mismatch in the availability of emotional support persons on perceived birth stress among a US-based convenience sample (N = 1082).

Results
Individuals who stated during pregnancy that they desired support from their partner or a doula but who did not receive this support had significantly higher perceived childbirth stress (B = 12.5, P &lt; .0001; and B = 5.2, P = .02, respectively, measured on a scale of 0–100). The absence of any support persons (B = 6.7, P &lt; .001), the number of emotional support persons present (B = −5.8 for each additional support person, P = .01), and the feeling that the healthcare provider was busy or distracted during labor (B = 15, P &lt; .001) was significantly associated with childbirth stress. Virtual support did not attenuate these effects.

Conclusions and Implications
Not being able to have desired emotional support during labor was associated with significantly higher childbirth stress, even after adjusting for clinical childbirth complications. These effect sizes were substantial, comparable to the elevated stress associated with cesarean section delivery and other childbirth complications. These findings underscore the importance of preventing an evolutionary mismatch in emotional needs during labor by ensuring access to continuous support, even during public health emergencies.
