Narrative, Activism, and Aesthetics: Composing Electroacoustic Music for Mexicans
Authors: Soria Luz Rosalia 
Published: February 2023

Abstract
This article presents the composition process of three electroacoustic pieces belonging to the project Contra el racismo en Mexico (Against Racism in Mexico). The project aims to raise awareness about racism. Concerned with engagement, national identity, and the invisibility of racism in Mexico, I included fragments of interviews with Mexicans to share their views and call for a change. In the article, aspects such as compositional methodology, selection of sound materials, cultural aspects addressed in each piece, and engagement with society are discussed. Aesthetics and form are also examined, as they played a significant role when composing electroacoustic music for broad audiences. I argue that these pieces may have documentary qualities that depict racism in Mexico.
Towards Text-to-SQL over Aggregate Tables

ABSTRACT
Text-to-SQL aims at translating textual questions into the corresponding SQL queries. Aggregate tables are widely created for high-frequent queries. Although text-to-SQL has emerged as an important task, recent studies paid little attention to the task over aggregate tables. The increased aggregate tables bring two challenges: (1) mapping of natural language questions and relational databases will suffer from more ambiguity, (2) modern models usually adopt self-attention mechanism to encode database schema and question. The mechanism is of quadratic time complexity, which will make inferring more time-consuming as input sequence length grows. In this paper, we introduce a novel approach named WAGG for text-to-SQL over aggregate tables. To effectively select among ambiguous items, we propose a relation selection mechanism for relation computing. To deal with high computation costs, we introduce a dynamical pruning strategy to discard unrelated items that are common for aggregate tables. We also construct a new large-scale dataset SpiderwAGG extended from Spider dataset for validation, where extensive experiments show the effectiveness and efficiency of our proposed method with 4% increase of accuracy and 15% decrease of inference time w.r.t a strong baseline RAT-SQL.
A Critical Analysis of the Assumptions Underlying the Formulation of Maximum Potential Intensity for Tropical Cyclones
Authors: Makarieva Anastassia M. , Nefiodov Andrei V. 
Published: February 2023

Abstract
Emanuel’s concept of maximum potential intensity (E-PI) estimates the maximum velocity of tropical cyclones from environmental parameters assuming thermal wind (gradient-wind and hydrostatic balances) and slantwise neutrality in the free troposphere. E-PI’s key equation relates proportionally the radial gradients of saturated moist entropy and angular momentum. Here the E-PI derivation is reconsidered to show that the thermal wind and slantwise neutrality imply zero radial gradients of saturation entropy and angular momentum at an altitude where, for a given radius, the tangential wind has a maximum. It is further shown that, while E-PI’s key equation requires that, at the point of maximum tangential wind, the air temperature must increase toward the storm center, the thermal wind equation dictates the opposite. From the analysis of the equations of motion at the altitude of maximum tangential wind in the free troposphere, it is concluded that here the airflow must be supergradient. This implies that the supergradiency factor (a measure of the gradient-wind imbalance) must change in the free troposphere as the airflow tends to restore the balance. It is shown that such a change modifies the derivative of saturation entropy over angular momentum, which cannot therefore remain constant in the free troposphere as E-PI requires. The implications of these findings for the internal coherence of E-PI, including its boundary layer closure, are discussed.
Role of the Aleutian Low in Modulating the Connection between the Moderate El Niño and the Following Spring North Tropical Atlantic SST Anomalies
Authors: Chen Wei 
Published: February 2023

Abstract
El Niño events are likely to be followed by significant positive sea surface temperature anomalies (SSTAs) over the north tropical Atlantic (NTA). We find that this is not always true for El Niño with moderate intensity. Nearly half of the moderate El Niño cases are followed by the strong NTA SSTAs, but others are followed by the weak NTA SSTAs, indicating the uncertainty in the connection between the moderate El Niño and the NTA. The differences in the El Niño–related NTA SSTAs are due to the different extratropical teleconnection between El Niño and the NTA, manifesting as a Pacific–North American (PNA) pattern. Further analysis suggests that the deepened Aleutian low (AL) induces the negative North Pacific SSTA, which is associated with a wave train propagating eastward, and, modulates the El Niño–generated PNA pattern. Therefore, El Niños that are accompanied by the strong AL induce a strong PNA pattern that, in turn, leads to the strong NTA SSTAs. The strength of the AL coinciding with El Niño plays a crucial role in modulating the connection between the moderate El Niño and the NTA SSTAs. This observational evidence about the uncertainty in the El Niño–NTA connection and the role of the AL in modulating this connection is further supported by the model simulations that participated in phase 6 of the Coupled Model Intercomparison Project (CMIP6). These results indicate that the combined effects of El Niño and the AL must be considered to fully understand the NTA SSTA variability.

Significance Statement
El Niño events often lead to significant warming over the north tropical Atlantic (NTA). We find that the strong El Niño almost always is accompanied by the strong NTA sea surface temperature anomalies (SSTAs), whereas the moderate El Niño can be followed by either the strong or weak NTA SSTAs, indicating the uncertainty in the connection between the moderate El Niño and the NTA SSTAs. Further analysis demonstrates that El Niño, which is accompanied by the strong (weak) Aleutian low leads to the strong (weak) NTA SSTAs, suggesting that the role of the Aleutian low must be considered to fully understand the El Niño–NTA connection.
Assessment of OTT Parsivel2 Raindrop Fall Speed Measurements
Authors: Saha Rupayan , Testik Firat Y. 
Published: February 2023

Abstract
This study was to assess the raindrop fall speed measurement capabilities of OTT Parsivel2 disdrometer through comparisons with measurements of a collocated High-speed Optical Disdrometer (HOD). Raindrop fall speed is often assumed to be terminal in relevant hydrological and meteorological applications, and generally predicted using terminal speed–raindrop size relationships obtained from laboratory observations. Nevertheless, recent field studies have revealed that other factors (e.g., wind, turbulence, raindrop oscillations, and collisions) significantly influence raindrop fall speed, necessitating accurate fall speed measurements for many applications instead of reliance on laboratory-based terminal speed predictions. Field observations in this study covered rainfall events with a variety of environmental conditions, including light, moderate, and heavy rainfall events. This study also involved rigorous laboratory experiments to faithfully identify the internal filtering and calculation algorithm of OTT Parsivel2. Our assessments revealed that, for the smaller diameter bins, Parsivel2 filters out many of the observed raindrops that fall faster than predicted terminal speeds, bringing down the mean fall speed for those size bins without observational evidence. Furthermore, Parsivel2 fall speed measurements exhibited notable artificial bell-shaped deviations from the predicted terminal speeds toward subterminal fall starting at around 1 mm diameter raindrops with peak deviations around 1.625 mm diameter bin. Such bell-shaped fall speed deviation patterns were not present in collocated HOD measurements. Assessment results along with the faithfully identified Parsivel2 algorithm are presented with discussions on implications on reported raindrop size distributions (DSD) and rainfall kinetic energy.
Spatial Variation in the Synoptic Structure of Convective Systems over the Great Plains
Authors: Verevkin Iaroslav , Folkins Ian 
Published: February 2023

Abstract
During the summer, rainfall over the Rocky Mountains peaks in the afternoon. The diurnal time of maximum rain becomes progressively delayed in going eastward from the Rocky Mountains, such that over much of the Great Plains, maximum rain occurs near 0300 local time. We use Rapid Refresh (RAP) reanalysis data from July and August of 2009–19 to show that there is continuous spatial variation in the mean structure of the high-rain events that occur along this anomalous diurnally propagating rainfall feature. High-rain events that occur farther from the Rockies are more likely to be associated with a larger warm anomaly to the south of the rain event center, a smaller cold anomaly, a larger negative surface pressure anomaly, and increased low-level southerly meridional wind. We also use the Integrated Multi-Satellite Retrievals for GPM (IMERG) rainfall dataset to show that, on hourly time scales, afternoon rainfall that occurs over the Rocky Mountains propagates eastward onto the Great Plains but is rapidly attenuated and becomes negligible east of 100°W. This eastward rainfall propagation appears to be mediated in part by the formation of a low-level cold anomaly and increased surface pressure over the Rocky Mountains, a reversal of the upslope wind, and increased low-level zonal mass convergence over the adjacent near plains.

Significance Statement
Models have difficulty in simulating the diurnal time of nocturnal rainfall over the Great Plains. Deep convection in this region is often associated with severe weather. Rainfall variability over the Great Plains has a significant impact on soil moisture and agricultural productivity. This paper explores how the structure of deep convective rain events over the Great Plains varies with longitude. The results improve our understanding of deep convection development in the Great Plains and have the potential to contribute to improved forecasts of convective rainfall.

Published: February 2023

Background Pistacia integerrima (PI) galls, being rich in polyphenolic compounds, owing to its high restorative worth and restricted assets and exorbitant utilization lead to the overexploitation of the species and availability issues. It is expected to categorise under the red list of threatened taxa. Ayurveda text Bhaishajaya Ratnavali mentioned Quercus infectoria (QI) as ‘pratinidhi’ or substitute of PI and Yogaratnakara (abhavvarga) text reference indicated Terminalia chebula (TC) having the same therapeutic character as in PI. Hence, this study was focused on the comparative quantification of major polyphenolic compounds in aqueous and hydro-alcoholic extracts of PI, QI and TC by liquid chromatography and tandem mass spectroscopy (LC-MS/MS). Objectives The LC-MS/MS method was used for the determination of polyphenolic compounds in aqueous and hydro-alcoholic extracts of PI, QI and TC. Materials and Methods The LC-MS/MS method was developed for the quantification of targeted polyphenolic compounds and validated in terms of linearity, accuracy, precision, limit of detection and limit of quantification. Analysis performed by LC-MS/MS 6460 C triple quad coupled with Agilent HPLC. The chromatographic separation was performed on the RP C18 column with gradient elution. Results The developed method of LC-MS/MS was used for the quantitative estimation of gallic acid, corilagin acid, caffeic acid, syringic acid, rutin hydrate, ellagic acid, quercetin and morin hydrate in PI, QI and TC. As per method validation parameters, calibration plots were found to be linear, accurate, precise and specific for LC-MS/MS. The calibration plot exhibited an excellent coefficient of determination ( R2 ≥ 0.99), and extraction recovery was found 96.20%–103.71%. Gallic acid and ellagic acid are the most abundant compound among eight targeted polyphenolics in all extracts. Conclusion The finding of LC-MS/MS analysis of polyphenolic compounds in aqueous and hydro-alcoholic extracts indicates that PI, QI and TC are having phytochemical similarities up to an extent in polyphenolic compounds as a secondary metabolite; however, a firmer opinion can be formed after a comparative efficacy study and the evaluation of all three extracts.
Cartilage degeneration of patellofemoral joint occurs in open wedge high tibial osteotomy, rather than in hybrid closed wedge high tibial osteotomy, during the early postoperative period: A qualitative analysis using MRI T2 mapping

Published: February 2023

Purpose After high tibial osteotomy, the patella may change position and osteoarthritis of the patellofemoral joint (PFJ) may occur. It was hypothesized that the course of PFJ degeneration would differ between open wedge high tibial osteotomy (OWHTO) and hybrid closed wedge high tibial osteotomy (hybrid HTO). Accordingly, this study aimed to evaluate the qualitative changes in PFJ articular cartilage, during the early postoperative period after OWHTO and hybrid HTO. Methods This was a retrospective observational study of 75 knees that underwent OWHTO (N = 37) or hybrid HTO (N = 38) for medial knee osteoarthritis. OWHTO and hybrid HTO were indicated for corrections of less than 10° and more than 10°, respectively. MRI of all knees was performed before and 6 months after surgery to evaluate patellar cartilage in sagittal images for T2 mapping. Three regions of interest (medial, middle, and lateral facets) were defined in the articular cartilage, and T2 values were measured. Patellar tilting angle, lateral shift ratio, and patellar height were compared before and after surgery. Results There was no significant change in arthroscopic findings of PFJ articular cartilage between the OWHTO and hybrid HTO groups. In the OWHTO group, the mean T2 value of medial and middle facets increased significantly (lateral, 43.0 ± 3.9 to 43.7 ± 3.5; middle, 44.2 ± 3.9 to 46.2 ± 3.8; medial 41.0 ± 4.3 to 42.4 ± 4.0). Conversely, no significant change was observed in the hybrid HTO group (lateral, 41.1 ± 4.0 to 42.3 ± 4.0; middle, 43.6 ± 4.2 to 44.5 ± 4.3; medial, 40.7 ± 4.1 to 41.5 ± 4.5). Patellar height decreased and increased in the OWHTO and hybrid HTO groups, respectively, and patellar tilt decreased in the OWHTO group. Lateral shift ratio decreased significantly in both groups. Conclusions OWHTO with a small correction angle may result in qualitative changes in PFJ articular cartilage from an early stage, while hybrid HTO with a relatively large correction angle is unlikely to affect PFJ articular cartilage.

Published: February 2023

The functional results of proximal row carpectomy with a proximal capitate resurfacing using a pyrocarbon implant were evaluated in a retrospective, multicentric, multi-operator study. The outcomes of patients operated on at five surgical centres between January 2005 and December 2018 were reviewed. The data were collected by an independent observer during standardized consultations. Based on 30 patients with a mean follow-up of 7 years, the median range of flexion and extension was 65° and the median radioulnar tilt was 45°. The median Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score was 14 and the improvements in strength and pain were good. Compared with the preoperative values, significant improvements were seen in the flexion and extension range of motion, radioulnar tilt and pain score. No postoperative complications were recorded. Level of evidence: IV
Tiktoking COVID-19 with frontline workers
Authors: Al-Rawi Ahmed , Zemenchik Kiana 
Published: February 2023

Introduction/Objective During the COVID-19 pandemic, frontline workers have taken to social media platforms to discuss a variety of issues that concern their personal and professional lives. In particular, TikTok's increased prominence as a social media channel has proved significant for enhancing the public presence of healthcare workers and their ability to disseminate content to a wider audience. The ways that healthcare workers use TikTok draws attention to the type of health information disseminated to the public through social media platforms. This provides the public with succinct and often visually entertaining information that may not be otherwise distributed to them directly from elsewhere. This study also provides relevant insights into how social media—TikTok in particular—can be used as a tool for disseminating knowledge about COVID-19 related topics and combatting misinformation by using the credibility of frontline workers. Methods This study collected a sample of over 2100 TikTok videos posted by healthcare workers that were coded according to the dominant overarching themes. Results The themes that arose from this sample were: (1) healthcare workers’ mental health and working conditions, (2) healthcare heroes/appreciation, (3) criticism against official authorities, (4) countering misinformation, (5) humor/satire, and (6) educational content. Conclusion Due to the rise in public appreciation for frontline workers, examining the effects of the pandemic through the eyes of frontline workers has drawn attention to their lived realities in various forms. This study provided some insight into how frontline workers use TikTok to disseminate information and education to the public, often relying on their perceived credibility.

Background Sleep disorders are common in patients with multiple sclerosis and have a bidirectional interplay with fatigue and depression. Objective To evaluate the effect of treatment with oral dimethyl fumarate on the quality of sleep in relapsing-remitting multiple sclerosis. Methods This was a multicentre observational study with 223 relapsing-remitting multiple sclerosis subjects starting treatment with dimethyl fumarate ( n=177) or beta interferon ( n=46). All patients underwent subjective (Pittsburgh Sleep Quality Index) and objective (wearable tracker) measurements of quality of sleep. Fatigue, depression, and quality of life were also investigated and physical activity was monitored. Results Patients treated with dimethyl fumarate had significant improvement in the quality of sleep as measured with the Pittsburgh Sleep Quality Index ( p<0.001). At all-time points, no significant changes in Pittsburgh Sleep Quality Index score were observed in the interferon group. Total and deep sleep measured by wearable tracker decreased at week 12 with both treatments, then remained stable for the total study duration. Depression significantly improved in patients treated with dimethyl fumarate. No significant changes were observed in mobility, fatigue and quality of life. Conclusion In patients with relapsing-remitting multiple sclerosis, the treatment with dimethyl fumarate was associated with improvements in patient-reported quality of sleep. Further randomised clinical trials are needed to confirm the benefits of long-term treatment with dimethyl fumarate.

Published: February 2023

Study Design Randomized controlled trial Objective The primary objective of this study was to compare the short-term clinical and radiological outcomes of full-endoscopic lumbar laminotomy (FEL) with those of subtotal lumbar laminectomy (STL) for lumbar spinal stenosis (LSS). Methods In this prospective randomized trial a total of 52 patients were enrolled from May 2016 to September 2021 after providing written informed consent. The authors investigated 45 patients who were followed up for more than 6 months. Results There were significant improvements in visual analogue scale (VAS) and Oswestry Disability Index (ODI) scores after the operation in both groups. The FEL group tended to have significantly shorter hospital stay. Interestingly, a statistically significant increase in postoperative lumbar lordosis and segmental angle was observed in the FEL group and both groups, respectively. Spondylolisthesis was exacerbated or newly developed in five of the 21 patients (24%) in the STL group. In contrast, improvement in spondylolisthesis was observed in two of the 24 patients (8%) in the FEL group. There were no complications that resulted in fatal sequelae and no significant difference in the complication rate. Conclusions The clinical results of FEL were similar to those of STL. In addition, the results of FEL were superior to those of STL in terms of a decrease in the postoperative length of stay and radiologic instability, such as iatrogenic spondylolisthesis. The results of this study indicate that FEL is a comparable surgical method to STL for LSS.

Background: Youth represent 21% of the Egyptian population; such proportion can create a leading demographic power for economic development and transition. However, with the current COVID-19 pandemic, everyone is exposed to more than usual stressors, adding a burden to their mental health and well-being. Aim: This study aims to understand the pandemic’s effect on youth’s mental health in Egypt to strengthen the intervention areas needed to tackle such issues. Methods: This observational, analytical, cross-sectional study employed internet platforms of Facebook & WhatsApp groups for a web-based survey that included 412 respondents between 15 and 30 years old. RESULTS The median age of the respondents was 22 years. At least 30% reported increased violence in the street and/or household, and 27.4% of the respondents have considered visiting a psychiatrist during the last period. Conclusion: It is evident that the current situation is unprecedented and challenging for everyone; however, some populations are more vulnerable than others. Thus, it’s important to support young people to ensure that the whole community can withstand the pandemic. The governments should support and mitigate some of the stresses that can be directly amended, like the education and job security concerns.
