Abstract
The aim of this study is to evaluate the association of perinephric fat volume (PNFV) and the Mayo Adhesive Probability (MAP) score with time to clamping (TTC) in robot-assisted partial nephrectomy (RAPN). The study subjects consisted of 73 tumors in 72 patients who underwent trans-peritoneal RAPN at a single cancer center between February 2020 and July 2022. Clinical characteristics including R.E.N.A.L. Nephrometry score, MAP score and PNFV were evaluated in a multivariate analysis in relation to TTC, which was classified into two groups based on median TTC. MAP score and PNFV were analyzed separately. PNFVs were measured by SYNAPSE VINCENT® by a single expert urologist. Median TTC was 67 (range: 36-119) minutes. Spearman’s rank correlation analysis indicated that a significant correlation was observed between PNFV and MAP score with a value of 0.81 (p < 0.0001). Univariate analysis revealed that R.E.N.A.L. nephrometry score ≥7 (p = 0.036), posterior tumor location (p = 0.033), Map score ≥3 (p = 0.02) and PNFV ≥250ml (p = 0.02) were significant factors for prolonged TTC. In a multivariate analysis including PNFV (analysis 1), R.E.N.A.L. nephrometry score ≥7 (OR 3.54, p = 0.018) and PNFV ≥250cm3 (OR 3.94, p = 0.010) were independent factors for prolonged TTC. Similarly for MAP score (analysis 2), R.E.N.A.L. nephrometry score ≥7 (OR 3.54, p = 0.018) and Map score ≥3 (OR 3.94, p = 0.010) were independent factors for prolonged TTC. Both MAP score and PNFV may have a significant impact on TTC.
Experimental investigation of blade tip vortex behavior in the wake of asymmetric rotors
Authors: Abraham Aliza , Leweke Thomas 
Published: January 2023

Abstract
Wakes behind rotors such as wind turbines, propellers, and helicopters can have detrimental effects on downstream structures including increased structural loading. These wakes are characterized by helical vortices shed from the blade tips, which are subject to instabilities that cause the vortices to break down, reducing the strength of the wake. One type of instability, vortex pairing, can be triggered by introducing a slight asymmetry to the rotor. The current study investigates the effectiveness of different types of rotor asymmetries at triggering the pairing instability through an experimental campaign involving 14 rotor configurations. The leapfrogging distance, or the point where adjacent vortex loops swap positions, is used as a metric to compare the different types of asymmetries. For all cases tested, leapfrogging occurs between 4.1 and 1.8 rotor radii downstream of the rotor for the baseline and most perturbed configurations, respectively. Even a small perturbation of 6% of the vortex spacing reduces the leapfrogging distance by 25% relative to the baseline configuration. Some of the most interesting similarities and differences between cases are discussed in more detail, including the analogy between azimuthal and axial displacements, the importance of perturbation direction, and the effects of blade devices such as winglets and fins on the vortex system. The findings of the current study can be used to design rotors that passively accelerate wake recovery, mitigating detrimental effects on downstream structures.
On the effect of maintaining a fixed ambient temperature in the analysis of a photovoltaic device's performance
Authors: Frenkel Ido , Niv Avi 
Published: January 2023

Abstract
This article studies the consequence of shifting the point of view of photovoltaic system analysis from having a constant temperature to having a constant temperature of its ambient environment. To do so, we derive the power balance of the photovoltaic system—the rate equivalent of the first law of thermodynamics. We solve this equation in conjunction with the detailed balance photon rate equation to find the current and the temperature as a function of the cell's potential for a given bandgap, sources (sun and sky), ambient temperature, and heat conduction coefficient. We find the model to give the expected behavior of a photovoltaic system close to standard conditions. However, we find that the expected rise in efficiency for moderate concentration may flip to reduction if the cell’s ability to dissipate heat is not exquisite. Our model's applicability to any photovoltaic device is demonstrated by analyzing a thermoradiative cell—the inverse of a solar cell. We show compatibility with known models and the flexibility at which less-than-ideal systems can be analyzed in our approach. We believe that centering the analysis on a fixed ambient temperature is a more faithful representation of photovoltaic systems' experimental and real-life conditions. As such, it is essential for the development of photovoltaic technology. Also, this shift in point of view raises some fundamental questions regarding the energy carried by the electrical current that may prove vital for developing future photovoltaic concepts.

Abstract
Light scattering, whether caused by desired or spurious elements, is considered one of the main phenomena that present great challenges for the nonlinear (NL) optical characterization of turbid media. The most relevant disturbing factor is the random deformation suffered by the spatial intensity distribution of the laser beam due to multiple scattering. In this work, we report the IC-scan (intensity correlation scan) technique as a new tool to characterize the NL optical response of scattering media, by taking advantage of light scattering to generate speckle patterns sensitive to wavefront changes induced by the self-focusing and self-defocusing effects. Peak-to-valley transmittance curves, with a higher signal-to-noise ratio, are obtained by analyzing the spatial intensity correlation functions of the different speckle patterns, even in very turbid media where conventional NL spectroscopy techniques fail. To demonstrate the potential of the IC-scan technique, the NL characterization of colloids that contain a high concentration of silica nanospheres as scatterers, as well as gold nanorods, which act as NL particles and light scatterers, was performed. The results show that the IC-scan technique is more accurate, precise and robust to measure NL refractive indices in turbid media, overcoming limitations imposed by well-established Z-scan and D4σ techniques.

Abstract
Objective

There is hardly any information on the consumption of healthcare resources by older people with differentiated thyroid cancer (DTC). We analyzed these consumptions in older patients with DTC and compared patients 75 years and older with subjects aged 60–74 years.

Methods

A multicenter, retrospective analysis was designed. We recorded three groups of health resources consumption (visits, diagnostic procedures, and therapeutic procedures) and identified a subgroup of patients with high consumption of resources. We compared elderly patients (group 1, 60–74 years) with very old patients (group 2, ≥ 75 years).

Results

We included 1654 patients (women, 74.4%), of whom 1388 (83.9%) belonged to group 1 and 266 (16.1%) to group 2. In group 2, we found a higher proportion of patients requiring emergency department visits (7.89% vs 4.32%, P < 0.05) and imaging studies (24.1% vs. 17.3%; P < 0.05) compared to group 1. However, we did not find any significant difference between both groups in the consumption of other visits, diagnostic procedures, or therapeutic procedures. Overall, 340 patients (20.6%) were identified as high consumers of health resources, 270 (19.5%) in group 1 and 70 (26.3%) in group 2 (P < 0.05). Multivariate logistic regression analysis showed that the risk of recurrence and mortality, radioiodine treatment, tumor size, and vascular invasion were significantly related to the high global consumption of resources. However, the age was not significantly related to it.

Conclusion

In patients with DTC over 60 years of age, advanced age is not an independent determining factor in the consumption of health resources.
Electrospun ZnO-SnO2 Heterojunction Belts for Hydrogen Sensing
Authors: Bulemo Peresi Majura 
Published: January 2023

Abstract
Chemiresistive sensors are promising devices for H2 sensing in a broad range of applications including fuel cells, hydrogen storage systems, petroleum refinement, and diagnosis of oil-insulated transformers. Herein, electrospun ZnO-SnO2 belts were synthesized and applied as resistive-type sensing layers for H2 sensing. The ZnO-SnO2 belts containing 20 mol% of Zn relative to Sn showed a response (Ra/Rg) of 6.7, fast response speed (3.6 sec), and a distinguishable selectivity toward 5 ppm H2 at 400°C in the presence of HCHO, CH4, NH3, CO, and CO2. The sensor displayed a repeatable response when subjected to 15 cycles of alternate air and 5 ppm H2 exposure. A unique H2 sensing performance of the belts was attributed to their belt morphology, numerous surface pores, smaller crystal size, ZnO/SnO2 heterojunction, and ZnO metallization following H2 exposure.

Published: January 2023

Abstract
Background:
Robotic-assisted appendectomies and cholecystectomies are believed to increase cost compared to the gold standard laparoscopic approach. Two equally qualified surgeons performed both approaches over two years to evaluate intraoperative duration, time to discharge, conversion to open procedure, and readmission within 30 days.
Findings:
110 laparoscopic, 81 robotic-assisted appendectomies; and 105 laparoscopic and 165 robotic-assisted cholecystectomies were performed. Intraoperative time; laparoscopic appendectomy was 1.402 vs 1.3615 hours for robotic-assisted (P-value = 0.304); laparoscopic cholecystectomy was 1.692 vs 1.634 hours for robotic-assisted (P-value = 0.196). Time to discharge, was 38.26 for laparoscopic vs 28.349 hours for robotic-assisted appendectomy (P-value = 0.010), and 35.95 for laparoscopic vs 28.46 hours for robotic-assisted cholecystectomy (P-value = 0.002). Intraoperative conversion to open; only laparoscopic procedures were converted, one appendectomy and nine cholecystectomies. None in the robotic-assisted procedures. Readmissions, none in the appendectomy group and three in the cholecystectomy group. One laparoscopic and two robotic-assisted cholecystectomy patients were readmitted.
Conclusion:
Intraoperative times for robotic appendectomy and cholecystectomy were not longer than laparoscopic approach. Robotic approach shortened the time to discharge and the likelihood for conversion to open procedure.
Mindfulness in the Digital Workplace: an explorative study of the compatibility of mindfulness and technology
Authors: Wrede Sammy J.S. , Esch Tobias , Michaelsen Maren M. 
Published: January 2023

Abstract
Mindfulness has made its way into the business context. Simultaneously, several options for digitally encouraging mindfulness have been proposed in recent years, with opposing opinions questioning the compatibility of mindfulness and technology, claiming it is a paradox. This study aims to examine the compatibility of mindfulness and technology, i.e., how mindfulness and digitalization interact as compatible or incongruous phenomena in the digital working context. Semistructured interviews with 15 experts, all specializing in technology and mindfulness in the workplace, were conducted to generate hypotheses of digital mindfulness at work. Qualitative content analysis as well as content analysis via extraction were utilized in this study to explore mutual relationships. Information about workplace mindfulness, digitalization, technology and digital stress was synthesized. The themes “Mindful by Workplace-Design” (a) and “Working Mindfully in a Digital Cooperation” (b) resulted in suggested modifications for digital workplaces. The compatibility of the two phenomena escalated at the “Tipping Point” (c), reached beyond the use of mindfulness apps, i.e., when wearables are added. The results point out the limits of digital mindfulness, as well as opportunities for the cooperation of mindfulness and technology. For employers, the study provides guidance for shaping mindful digital workplaces and mindful work cultures.

Abstract:
An iodobenzene diacetate (IBD)-mediated simple and green method was determined for
the intramolecular oxidative cyclization of 3-aryl-2-pyridiylhydrazones of different aromatic
aldehydes in an aqueous medium at room temperature. This efficient strategy provides a route to
the synthesis of 3-aryl-1,2,4-triazolo[4,3-a]pyridines in water which eliminates the requirement to
use costly and unsafe volatile organic solvents. All reactions were carried out by just stirring the
reaction components in water at room temperature. This protocol provides a wide substrate scope
and good functional group tolerance.
Comparison of the Users’ Attitudes Toward Cannabidiol on Social Media Platforms: Topic Modeling Study
Authors: Li Yongjie , Yan Xiangyu , Wang Zekun , Ma Mingchang , Zhang Bo , Jia Zhongwei 
Published: January 2023

Background
As one of the major constituents of the cannabis sativa plant, cannabidiol (CBD) is approved for use in medical treatment and cosmetics because of its potential health benefits. With the rapid growth of the CBD market, customers purchase these products, and relevant discussions are becoming more active on social media.

Objective
In this study, we aimed to understand the users’ attitudes toward CBD products in various countries by conducting text mining on social media in countries with different substance management policies.

Methods
We collected posts from Reddit and Xiaohongshu, conducted topic mining using the latent Dirichlet allocation model, and analyzed the characteristics of topics on different social media. Subsequently, a co-occurrence network of high-frequency keywords was constructed to explore potential relationships among topics. Moreover, we conducted sentiment analysis on the posts’ comments and compared users’ attitudes toward CBD products on Reddit and Xiaohongshu using chi-square test.

Results
CBD-related posts on social media have been rapidly increasing, especially on Xiaohongshu since 2019. A total of 1790 posts from Reddit and 1951 posts from Xiaohongshu were included in the final analysis. The posts on the 2 social media platforms, Reddit and Xiaohongshu, were categorized into 7 and 8 topics, respectively, by the latent Dirichlet allocation model, and these topics on the 2 social media were grouped into 5 themes. Our study showed that the themes on Reddit were mainly related to the therapeutic effects of CBD, whereas the themes on Xiaohongshu concentrated on cosmetics, such as facial masks. Theme 2 (CBD market information) and theme 3 (attitudes toward CBD) on Reddit had more connections with other themes in the co-occurrence network, and theme 3 and theme 1 (CBD therapeutic effects) had a high co-occurrence frequency (22,803/73,865, 30.87%). Meanwhile, theme 1 (CBD cosmetics) on Xiaohongshu had various connections with others (169,961/384,575, 44.19%), and the co-occurrence frequency of theme 4 (CBD ingredients) and theme 1 was relatively prominent (27,128/49,312, 55.01%). Overall, users’ comments tended to be positive for CBD-related information on both Reddit and Xiaohongshu, but the percentage was higher on Xiaohongshu (82.25% vs 86.18%; P<.001), especially in cosmetics and medical health care products.

Conclusions
The CBD market has grown rapidly, and the topics related to CBD on social media have become active. There are apparent differences in users’ attitudes toward CBD in countries with different substance management policies. Targeted CBD management measures should be formulated to suit the prevalence of CBD use of each country.

Published: January 2023

Background
The strategic plan of the Ethiopian Ministry of Health recommends an electronic medical record (EMR) system to enhance health care delivery and streamline data systems. However, only a few exhaustive systematic reviews and meta-analyses have been conducted on the degree of EMR use in Ethiopia and the factors influencing success. This will emphasize the factors that make EMR effective and increase awareness of its widespread use among future implementers in Ethiopia.

Objective
This study aims to determine the pooled estimate of EMR use and success determinants among health professionals in Ethiopia.

Methods
We developed a protocol and searched PubMed, Web of Sciences, African Journals OnLine, Embase, MEDLINE, and Scopus to identify relevant studies. To assess the quality of each included study, we used the Joanna Briggs Institute quality assessment tool using 9 criteria. The applicable data were extracted using Microsoft Excel 2019, and the data were then analyzed using Stata software (version 11; StataCorp). The presence of total heterogeneity across included studies was calculated using the index of heterogeneity I2 statistics. The pooled size of EMR use was estimated using a random effect model with a 95% CI.

Results
After reviewing 11,026 research papers, 5 papers with a combined total of 2439 health workers were included in the evaluation and meta-analysis. The pooled estimate of EMR usage in Ethiopia was 51.85% (95% CI 37.14%-66.55%). The subgroup study found that the northern Ethiopian region had the greatest EMR utilization rate (58.75%) and that higher (54.99%) utilization was also seen in publications published after 2016. Age groups <30 years, access to an EMR manual, EMR-related training, and managerial support were identified factors associated with EMR use among health workers.

Conclusions
The use of EMR systems in Ethiopia is relatively low. Belonging to a young age group, accessing an EMR manual, receiving EMR-related training, and managerial support were identified as factors associated with EMR use among health workers. As a result, to increase the use of EMRs by health care providers, it is essential to provide management support and an EMR training program and make the EMR manual accessible to health professionals.

Objective: The present studies discuss the anticancer activity of different topoisomerase II inhibitors with docking study.
Methods: The work reports the synthesis of novel diethyl (4-oxo-4H-chromen-3-yl)(5-substituted phenyl-1,3,4-thiadiazol-2-ylamino)methyl phosphonate derivatives 6(a-j). They were synthesized through one-pot three-component Kabachnik-Fields reaction by using ultrasonicator processor, at room temperature in presence of Zirconium oxychloride (ZrOCl2).
Results: The structures of the synthesized compounds were confirmed by spectral analysis. The synthesized derivatives 6(a-j) were evaluated for their in vitro anticancer activity against human cancer cell lines such as DU 145 (Human Prostate Cancer) and MCF-7 (Breast cancer) and also on non-tumor cell lines such as MCF-10 (normal breast epithelial cell) by MTT assay. From the anticancer screening results data, compound 6e was found to be the most potent anticancer compound among the synthesized compounds against MCF-7 and DU 145 cancer cell lines with IC50 value of 2.97 µM and 3.11 µM, respectively. The compound 6h has shown cell cycle arrest at G2/M phase, along with the decrease of cells at G0/G1 phage. The compound 6h was able to induce apoptosis in DU 145 cell lines. The synthesized compounds 6(a-j) were further evaluated for their topoisomerase II inhibitory activity.
Conclusion: The anticancer screening result and MTT assay, along with the docking study shows that the synthesised derivative are active anticancer agent against MCF-10, DU-145 and MCF-7 cell line.
CRECIMIENTO ECONÓMICO, TIPO DE CAMBIO REAL Y EXPORTACIONES MANUFACTURERAS DE MÉXICO, 1998-2020
Authors: Castañeda Martínez Ana Erika , López González Teresa 
Published: January 2023

El principal objetivo del artículo es comprobar empíricamente, para el caso de México en el periodo 1998-2020, la hipótesis central del enfoque neoestructuralista que sostiene la existencia de una relación positiva entre el tipo de cambio real y el crecimiento económico. Utilizamos un modelo de cointegración del tipo Engle y Granger. Exponemos hechos estilizados sobre los flujos comerciales que muestran algunas características de dichos flujos, los cuales permiten entender por qué en la economía mexicana no se registraron las derramas de la difusión tecnológica (spillovers from technology difussion) que, según la nueva teoría del comercio internacional, son inducidas por la liberalización comercial, más concretamente por las exportaciones de mercancías. Estos hechos estilizados contribuyen a la interpretación de los resultados del modelo de cointegración, así como a identificar algunos de los factores de la restricción externa al crecimiento en la economía mexicana (Thirlwall, 1979).

ECONOMIC GROWTH, REAL EXCHANGE RATE AND MEXICO’S MANUFACTURING EXPORTS, 1998-2020
ABSTRACT
The main objective of this article is to empirically test, for the case of Mexico over the period 1998-2020, the central hypothesis of the Neostructuralist approach, namely the existence of a positive relationship between the real exchange rate and economic growth. To this purpose, a cointegration model of the Engle and Granger type is used. Stylized facts about trade flows are presented showing some characteristics of the said flows, which allow us to understand why in the Mexican economy the spillovers of technological diffusion are not seen, spillovers which, according to the new international trade theory, are induced by trade liberalization, more specifically by merchandise exports. These stylized facts contribute to the interpretation of the results of the cointegration model as well as to identify some of the factors involved in the external constraints on the growth rate of the Mexican economy (Thirlwall, 1979).
