TENISKA TERMINOLOGIJA NA ENGLESKOM I SRPSKOM JEZIKU
Authors: Panić Kavgić Olga V.
Published: July 2021

Rad se bavi terminologijom tenisa – jednog od najstarijih i najpopularnijih sportova u svetu, i to engleskim terminima kao izvornim, i srpskim, kao pozajmljenicama ili prevodnim ekvivalentima. Dvojezični korpus za istraživanje predstavlja iscrpna paralelna lista od 950 teniskih termina na engleskom jeziku i odgovarajućih ekvivalenata na srpskom, sastavljena na osnovu relevantnih štampanih i elektronskih izvora. Kvalitativna analiza prikupljenih jedinica sastoji se iz prikaza postupaka primenjenih u tvorbi izvornih engleskih termina, opisa primerâ metafore, metonimije, eponimije i ikoničnosti u oba jezika, te, u slučaju srpske terminologije, utvrđivanja osobina pozajmljenica i postupaka kojima su prevedeni izvorni izrazi. Pretpostavka je da većina termina na srpskom jeziku predstavlja po obličkoj realizaciji očigledne, a po nastanku preoblikovane anglicizme (forhend, gem, viner, čelendž, čip-end-čardž), te, u manjoj meri, ekvivalente dobijene postupcima strukturnog (linijski sudija, osnovna linija, oko sokolovo, neiznuđena greška), definicionog (meč bez takmičarskog značaja u ekipnom teniskom takmičenju) i direktnog prevođenja (teren, sudija, udarac, prednost), ili pak funkcijske aproksimacije (skupljač loptica, meč lopta, dijagonala). Cilj rada jeste utvrđivanje, opis i klasifikacija primerima potkrepljenih izvornih tvorbenih postupaka, semantičkih fenomena prenosa značenja u terminologiji u oba jezika, ali i, pre svega, postupaka kojima su srpski termini nastali, bilo pozajmljivanjem, ili prevođenjem izvorne teniske terminologije sa engleskog jezika.

Authors: Halas Popović Ana
Published: July 2021

U ovom radu predstavlja se model definisanja značenja sinonima primenjen prilikom sastavljanja Englesko-srpskog kontrastivnog rečnika sinonima, jedinstvenog kod nas, na kome je rad započet na Odseku za anglistiku Filozofskog fakulteta Univerziteta u Novom Sadu 2016. godine. Cilj ovog rada je da izloži teorijsko-metodološke postavke pomenutog modela, ali i njegove praktične aspekte uključujući ilustraciju njegovog funkcionisanja u različitim konkretnim slučajevima. Posebna pažnja biće posvećena održanju principa uniformnosti definicija, posebno u retkim primerima u kojima su se javile izvesne poteškoće u primeni datog modela, čiju osnovu čini ovaj princip. Ovi slučajevi ukazali su na činjenicu da univerzalnost primene modela zahteva fleksibilnije definisanje principa uniformnosti definicija tako da on predviđa upotrebu identičnog obrasca u svim definicijama u članku, ali da dozvoljava i opravdane varijacije i modifikacije datog obrasca u meri koja neće ugroziti transparentnost međusobne značenjske povezanosti sinonima u okviru jednog rečničkog članka.

Published: July 2021

Aim: This study aimed to evaluate the pH, Ca2+ release, solubility, and antimicrobial activity of calcium hydroxide (Ca(OH)2) pastes in association with different substances. Methods: Sixty acrylic teeth (n=10) were filled with pastes that associated Ca(OH)2 with the following substances: benzalkonium chloride 5% (G1) and 50% (G2) both in propylene glycol, arnica glycolic extract (G3), green tea glycolic extract (G4), Calen/PMCC™ (G5), and Calen™ (G6). In the group G1 to G4 were used 1g of Ca(OH)2 powder with 0,8g of vehicle. pH and Ca2+ release was measured after 7, 15, and 30 days. For solubility, micro-CT was used immediately and at the periods of 7, 15, and 30 days. For the antimicrobial analysis, a biofilm of E. faecalis was induced in vitro on bovine dentin discs. Live/dead viability dye and confocal scanning microscopy were used. Results: The highest pH values occurred on the first 7 days, and the G6, G1, G3, and G5 presented the highest pH values at this period (P <0.05). Ca2+ release was higher in all groups at 7 days, with the highest values observed in G1, G5, and G6. The volume of all pastes showed no significant difference in the intragroup analysis at 7 and 15 days (P <0.05). G1 and G2 showed the highest antimicrobial action (P <0.05). For the biovolume, there was difference between the G6 and the other groups (P >0.05) with G1 presenting the lowest values. Conclusion: Benzalkonium chloride 5% increases the antimicrobial action of the Ca(OH2), without impairs physicochemical properties.

Published: July 2021

La isquemia mesentérica es una condición que puede volverse muy grave y ser letal, más aún en los casos agudos. Un tratamiento precoz es muy importante. Se presentaron cuatro casos consecutivos tratados por nuestro equipo con trombosis, o disección o aneurismas de arterias mesentérica superior y tronco celíaco, se revisaron las indicaciones y se evaluaron los tratamientos llevados a cabo. Se utilizaron procedimientos endovasculares en todos, técnicamente en forma exitosa, evitando que progrese a un desenlace peligroso. Hubo diversidad de técnicas endovasculares adaptándolas a cada caso. En ningún paciente se requirió un acceso quirúrgico abierto para completar el tratamiento realizando las intervenciones prontas. El manejo endovascular de las lesiones mesentéricas es factible y replicable, y en nuestros casos podría haber prevenido una necrosis intestinal así como la necesidad de cirugías resectivas.

Allergic conjunctivitis (AC) is an inflammation of the conjunctiva due to allergens that come in contact with the eye. Seasonal AC and perennial AC are the most commonly encountered subtypes. Each can be identified by itching, tearing, and swelling or inflammation of the eye, and these symptoms can contribute to decreased quality of life for patients. Many patients will seek symptomatic relief with topical ophthalmic formulations. Pharmacists and pharmacy technicians should be familiar with the clinical presentation of AC to best recommend appropriate treatments for AC. This review illustrates counseling interactions between a patient and a pharmacist to provide a clear understanding about recommending over-the-counter treatment options for patients. Effective communication is a cornerstone for pharmacists and pharmacy technicians to optimize patient management and relay vital information for the management of AC, such as assisting patients with therapies that can help provide relief of symptoms.
Amine Modified Magnetic Diatomite Particles as an Effcicent Adsorbent for Pecticide Removal
Authors: Alacabey İhsan
Published: July 2021

Pesticides are one of the most critical emerging contaminants which are highly toxic for the environment and have potential risk to human health. In this study, surface-modified magnetic diatomite particles (m-DE-APTES) have been suc-cessfully synthesized and used as a sorbent for the removal of endosulfan from an aqueous solution. Magnetic diatomite particles with surface modification were characterized by Fourier transform-infrared spectroscopy (FT-IR), scan-ning electron microscopy (SEM), energy dispersive X-ray (EDX), electron spin resonance (ESR), and surface area measurements. Characterization results sug-gest that magnetic diatomite has a high surface area and porous structure. In addition, m-DE-APTES has higher adsorption capacity (97.2 mg/g) for en-dosulfan pesticide than unmodified diatomite particles (DE) (16.6 mg/g). The adsorption data fit the Langmuir model (R2=0.9905), and the adsorption process took place spontaneously with the values of ΔGo as -2.576. In conclusion, the surface-modified diatomite particles are promising alternative adsorbents for pesticide removal from aqueous solutions.
Antibiotic Removal from Aquatic Environment with Activated Carbon Produced from the Pumpkin Seeds
Authors: Alacabey İhsan
Published: July 2021

Antibiotics are among the most critical environmental pollutant drug groups. One of the methods used to remove this pollution is adsorption. In this study, activated carbon was produced from the pumpkin seed shell and then modified with KOH. This adsorbent obtained was used in the re-moval of ciprofloxacin from aqueous systems. Fourier Transform-Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), elemental, X-ray Photoelectron Spectroscopy (XPS), Brunauer-Emmett-Teller (BET) and Zeta analyzes were used for the characterization of the ad-sorbent. In particular, the surface area was found to be a very remarkable value of 2730 m2/g. The conditions of the adsorption experiments were optimized based on interaction time, adsorbent amount, pH and temperature. Over 99% success has been achieved in removal works carried out under the most optimized conditions. In addition, it was determined that the Langmuir isotherm is the most suitable model for the adsorption interaction.
Variability of Gravel Pavement Roughness: Analysis of the Impact on Vehicle Response and Driving Comfort
Authors: Žuraulis Vidas , Sivilevičius Henrikas , Šabanovič Eldar , Ivanov Valentin , Skrickij Viktor
Published: July 2021

The gravel road pavement has a lower construction cost but poorer performance than the asphalt surface. It also emits dust and deforms under the impact of vehicle loads and ambient air factors. The resulting ripples and ruts are constantly deepening, increasing vehicle vibrations and fuel consumption, reducing safe driving speed and comfort. In this article, existing pavement quality evaluation indexes are analysed, and a methodology for their adaptation for roads with gravel pavement is proposed. This article reports the measured wave depth and length of the gravel pavement profile by the straightedge method of a 160 m long road section in three road exploitation stages. The measured pavement elevation was processed according to ISO 8608, and vehicle frequency response has been investigated using simulations in MATLAB/Simulink. The applied International Roughness Index (IRI) analysis showed that a speed of 30-45 km/h instead of 80 km/h provides the objective results of IRI calculation on the flexible pavement due to a decreasing velocity of vehicle's unsprung mass on a more deteriorated road pavement state. The influence of the corrugation phenomenon of gravel pavement has been explored, identifying specific driving safety and comfort cases. Finally, an increase in the Dynamic Load Coefficient (DLC) at a low speed of 30 km/h on the most deteriorated pavement and a high speed of 90 km/h on the middle-quality pavement demonstrates the demand for timely gravel pavement maintenance and the complicated prediction of a safe driving speed for drivers.

Supplier selection (SC) product life cycle cost (SCPLCC) is an important consideration among corporations, SCPLCC problem has become associated with deciding how one supplier should be selected from possible alternatives. In this study, we applied two types of goal programming, multiobjective linear programming and revised multichoice goal programming to develop a PLCC-based concept to solve the SCPLCC problem and construct a decision-making tool for application to a case of supply chain management in a Taiwanese light-emitting diode company in the high-tech industry. Our study main contribution Company managers can easily use the two approaches of the SCPLCC model with different parameters to solve SCPLCC model problems. Finally, we comparing five models found RMCGP with weighted linear goal programming had an adequate effect for application to the PLCC concept for high-technology company; this cloud makes company decision–makers focus on low PLCC and select a better supplier in sustainable supply chains goal.
Development and Validation of a Masking System for Mitigation of Low-Frequency Audible Noise from Electrical Substations

Published: July 2021

Low-frequency audible noise generated by the magnetostriction effect inherent to the operation of power transformers has become a major drawback, especially in cases where the electrical substation is located in urban areas subject to strict environmental regulations that imposes sound pressure limits, differing for day and night periods. Such regulations apply a +5 dB penalty if a tonal component of noise is present, which is clearly the case of magnetostriction noise, typically concentrated at twice the industrial frequency (50 Hz or 60 Hz, depending on the country). The strategy used to eliminate the tonal characteristics, therefore contributing to establish compliance with the applicable regulation and to alleviate the discomfort it causes to the human ear, consisted in superimposing to the substation noise a masking sound synthesized from “sounds of nature” with suitable intensities, to flatten the noise spectrum while enhancing the soundscape. The masking system (heavy-duty speakers powered by a microprocessor platform) was validated at an already judicialized urban scenario. Measurement results confirmed that the masking solution was capable of flattening the tonal frequencies, whose beneficial effect yielded the cancellation of the public civil action filed by the neighbors. The proposed solution is ready to be replicated to other scenarios.
The "Global Salt Cycle": Formation of Giant Salt Accumulations, a Result of Subduction, Mantle Upwelling, and Rifting
Authors: Johnsen Hans Konrad , Rueslatten Hakon G , Hovland Martin Torvald
Published: July 2021

The main objective of this communication is to describe the ‘Global Salt Cycle’. Giant salt accumulations are commonly found along continental margins of former rifts. The first stage in the accumulation process is saturation of newly formed oceanic crust with seawater. Final mobilisation and accumulation of the salts occurs during rifting, localised in the vicinity of relict subduction zones. Oceanic crust is created along the spreading ridges in the deep oceans of the Earth. It exchanges mass and energy with seawater in hydrothermal circulation cells that penetrate deep into the new and fractured crust. Water-rock interactions include the formation of hydrated and hydroxylated minerals, e.g., serpentinites and clay minerals. By incorporating hydroxyl groups and water in their crystal lattices, the salinity of remaining brines increases. Subduction of oceanic crust and serpentinised lithosphere transports water, hydrated minerals, and marine salts deep into the crust and mantle. Upon pressurisation and heating of the subducting slab, different parts of this water are expelled at different depths/temperatures. The resulting fluids will contain salts brought in with the slab, as well as new salts formed by water-rock interaction. The combination of elevated pressures and temperatures, water, salinity, and CO2, create permeability in the normally impermeable, peridotitic mantle, by altering the fluid-rock dihedral angles of mineral grains. This P/T-determined intergranular permeability allows ascent of saline fluids, under lithostatic pressure, within the mantle wedge, or the slab itself. The fluids produce a mechanically weakened and buoyant zone within the mantle wedge due to high pore pressure between mineral grains and reduced mantle density. During the lifetime of a subduction zone, a substantial accumulation of saline fluids within the mantle wedge and crust, is evident. Deep, fluid reservoirs accumulate between the subduction trench and the volcanic front. They may exist for hundreds of millions of years, even after the extinction of the subduction zone. Saline fluids may escape to the surface along deep faults, due to overfilling of available pores/fractures. Fluids within the mantle wedge may form rock melts or exist as supercritical, mineral rich fluids. The combination of reduced pressure due to rifting, and a saline and buoyant mantle, creates a mantle circulation that brings the accumulated, saline fluids, to crustal levels. Salts will therefore accumulate during initial stages of rifting as a result of massive fluid expulsion, phase change and boiling of mantle fluids. No extra energy is required to produce phase change and boiling. The result is formation of solid salts or dense brines/slurries invading fractured crustal rocks, or escaping to the surface/seabed. This process may take place both before and after the sea has invaded a continental rift.
T-proper Hypercomplex Centralized Fusion Estimation for Randomly Multiple Sensor Delays Systems with Correlated Noises
Authors: Fernández-Alcalá Rosa M. , Navarro-Moreno Jesús , Ruiz-Molina Juan C.
Published: July 2021

The centralized fusion estimation problem for discrete-time vectorial tessarine signals in multiple sensor stochastic systems with random one-step delays and correlated noises is analyzed under different T-properness conditions. Based on Tk, k=1,2, linear processing, new centralized fusion filtering, prediction, and fixed-point smoothing algorithms are devised. These algorithms have the advantage of providing optimal estimators with a significant reduction in computational cost compared to that obtained through a real or widely linear processing approach. Simulation examples illustrate the effectiveness and applicability of the algorithms proposed, in which the superiority of the Tk linear estimators over their counterparts in the quaternion domain is apparent.

Published: July 2021

Due to their well-defined plasmonic properties, gold nanorods (GNRs) can be fabricated with optimal light absorption in the near-infrared region of the electromagnetic spectrum, which make them suitable for cancer-related theranostic applications. However, their controversial safety profile, as a result of surfactant stabilization during synthesis, limits their clinical translation. We report a facile method to improve GNR biocompatibility through the presence of sodium dodecyl sulfate (SDS). GNRs (120 x 40 nm) were synthesized through a seed-mediated approach, using cetyltrimethylammonium bromide (CTAB) as a cationic surfactant to direct the growth of nanorods and stabilize the particles. Post-synthesis, SDS was used as an exchange ligand to modify the net surface charge of the particles from positive to negative while maintaining rod stability in an aqueous environment. GNR cytotoxic effects, as well as the mechanisms of their cellular uptake, were examined in two different cancer cell lines, Lewis lung carcinoma (LLC) and HeLa cells. We not only found a significant dose-dependent effect of GNR treatment on cell viability but also a time-dependent effect of GNR surfactant charge on cytotoxicity over the two cell lines. Our results promote a better understanding of how we can mediate the undesired consequences of GNR synthesis byproducts when exposed to a living organism, which so far has limited GNR use in cancer theranostics.

Published: July 2021

The outbreak of COVID-19 is a public health emergency that caused disastrous results in many countries. The global aim is to stop transmission and prevent the spread of the disease. To achieve it, every country needs to scale up emergency response mechanisms, educate and actively communicate with the public, intensify infected case finding, contact tracing, monitoring, quarantine of contacts, and isolation of cases. Responding to an emergency requires efficient collaboration and a multi-skilled approach (medical, information, statistical, political, social, and other expertise), which makes it hard to define one interface for all. As actors from different perspectives and domain backgrounds need to address diverse functions, the possibility to exchange available information quickly would be desirable. Geoportal provides an entry point to access a variety of data (geospatial data, epidemiological data) and could be used for data discovery, view, download, and transformation. It helps to deal with challenges like data analysis, confirmed cases geocoding, recognition of disease dynamics, vulnerable groups identification, and capacity mapping. Predicting and modeling the spread of infection, along with application support for communication and collaboration, are the biggest challenges. In response to all these challenges, we have established the Epidemic Location Intelligence System (ELIS) using open-source software components in the cloud, as a working platform with all the required functionalities.
High-resolution Bistatic Wind Lidar
Authors: Wilhelm Paul , Eggert Michael , Hornig Julia , Oertel Stefan
Published: July 2021

The high-resolution bistatic lidar developed at the Physikalisch-Technische Bundesanstalt (PTB) aims to overcome the limitations of conventional monostatic lidar technology which is widely used for wind velocity measurements in wind energy and meteorology applications. Due to the large measurement volume of a combined optical transmitter and receiver tilting in multiple directions, monostatic lidar generally has poor spatial and temporal resolution. It also exhibits large measurement uncertainty when operated in inhomogeneous flow, for instance, over complex terrain. In contrast, PTB’s bistatic lidar uses three dedicated receivers arranged around a central transmitter, resulting in an exceptionally small measurement volume. The coherent detection and modulation schemes used allow the detection of backscattered, Doppler shifted light down to the scale of single aerosols, realising the simultaneous measurement of all three wind velocity components. This paper outlines design details and the theory of operation of PTB’s bistatic lidar and provides an overview of selected comparative measurements. The results of these measurements have shown that the measurement uncertainty of PTB’s bistatic lidar is well within the measurement uncertainty of traditional cup anemometers, while being fully independent of its site and traceable to the SI units. This allows its use as a transfer standard for the calibration of other remote sensing devices. Overall, PTB’s bistatic lidar shows great potential to universally improve the capability and accuracy of wind velocity measurements, such as for the investigation of highly dynamic flow processes upstream and in the wake of wind turbines.
Strategy Control Model for Sustainable Manufacturinｇ through Rural Development
Authors: Wu Haishang
Published: July 2021

Additive manufacturing (AM) has been the core area of sustainable manufacturing commonly recognized for its high efficiency in enabling cost-effective production towards sustainability. There are three models this research constituted: In Collection-Recycling-Manufacturing (CRM) model, technologies and processes are benchmarked followed by Business model that evaluates industrial key criteria. However, these are insufficient for AM to effectively play dominant role as the realization requires human factors such as multi-entities authorities, policy making and AM society to initiate and execute the plan. Strategy control model focuses on human-centric approaches such as demography, population control, policy, regulations, and management. It investigates each nation’s demography, and enables strategy, plan and control to relocate overcrowding population to rural areas. It also produces robust workforce to support AM and materials recycling through the appropriate applications. Through the construction of AM and materials recycling, strategy control model creates job opportunities for those unemployed people. It further builds infrastructure for the livelihood of new residents and supports AM home-based business (HBB).

Published: July 2021

A comparative analysis of the equations of state for the detonation products of condensed explosives, which are most used in solving problems of the mechanical action of an explosion, is presented. For the most widespread (cited) equations of state of explosion products in the form of JWL, methods and algorithms are proposed for determining the correctness of specifying the coefficients included in this equation. To solve radiation-gasdynamic problems, including multicomponent mixtures, a version of the thermal equation of state of explosion products in the form of JWL is proposed, and a constant set for the most common explosives is recommended.

Large annotated datasets are crucial for training deep machine learning models, but they are expensive and time-consuming to create. There are already numerous public datasets, but a vast amount of unlabeled data, especially video data, can still be annotated and leveraged to further improve the performance and accuracy of machine learning models. Therefore, it is essential to reduce the time and effort required to annotate a dataset to prevent bottlenecks in the development of this field. In this study, we propose Anno-Mate, a pair of features integrated into the Computer Vision Annotation Tool (CVAT). It facilitates human–machine collaboration and reduces the required human effort. Anno-Mate comprises Auto-Fit, which uses an EfficientDet-D0 backbone to tighten an existing bounding box around an object, and AutoTrack, which uses a channel and spatial reliability tracking (CSRT) tracker to draw a bounding box on the target object as it moves through the video frames. Both features exhibit a good speed and accuracy trade-off. Auto-Fit garnered an overall accuracy of 87% and an average processing time of 0.47 s, whereas the AutoTrack feature exhibited an overall accuracy of 74.29% and could process 18.54 frames per second. When combined, these features are proven to reduce the time required to annotate a minute of video by 26.56%.
Densification and Fracture Type of Desert in Tight Oil Reservoirs: A Case Study of the Fuyu Tight Oil Reservoir in the Sanzhao Depression, Songliao Basin

Published: July 2021

The exploration of unconventional oil and gas, especially the exploration process of tight oil, is closely related to the evolution of tight reservoirs and the accumulation process. In order to investigate the densification and accumulation process of the Fuyu tight oil reservoir in the Sanzhao depression, Songliao Basin, through the new understanding of reservoir petrological characteristics, diagenesis and diagenetic sequence are combined with a large number of inclusions: temperature measurement, spectral energy measurement, and single-well burial history analysis, and then contrastive analysis with current reservoir conditions. The results prove that diagenesis is dominated by compaction and cementation, and the restoration of paleoporosity shows that its porosity reduction rate reached 67% and the densification process started in the early Nenjiang Formation and was finalized at the end of the Nenjiang Formation. The accumulation of the Fuyu oil layer generally has the characteristics of two stages and multiple episodes, and the main accumulation period is the end of the Mingshui Formation. The end of the Nenjiang Formation, where the main body of the reservoir is densified, is just a prelude to the massive expulsion of hydrocarbons in the Songliao Basin, which makes the Fuyu oil layer have the characteristics of first compacting and then accumulating. Through the above analysis, it can be seen that the accumulation of oil and gas in the Fuyu oil layer, Sanzhao depression, is more dependent on the fault-dominated transport system. In addition, it is believed that tight oil accumulation should have the characteristics of short-distance oil enrichment around the fault, and the development area of fracture deserts near the fault sand body should be the key area for further exploration.

Published: July 2021

Background: Several epidemiologic studies have reported that dietary acid load is associated with metabolic profiles; however, to our knowledge, the relationship of this dietary pattern with resting metabolic rate (RMR) among obese and overweight females remains unreported. Therefore, this study aimed to evaluate the association of dietary acid load RMR and metabolic components among overweight and obese adult women.Methods: This cross-sectional study was conducted on 375 Iranian adults, aged 18–48 years. Dietary acid load indexes were calculated by using a validated 147-item semi-quantitative FFQ. Biochemical and anthropometric measures were assessed using standard methods. An impedance fat analyzer was used to obtain the body composition and an indirect calorimeter was used to assess the RMR. Result: It was observed that after correction for potential confounders, DBP and NEAP and PRAL scores were inversely associated (P<0.05). NEAP index was inversely associated with RMR (β= -0.25, 95% CI=-0.1.5 to 2.08, P=0.02), and positively associated with WC (β= 1.009, 95% CI=-1.43 to 3.45, P=0.05) and WHR (β= 0.01, 95% CI= -0.01 to0.04, P=0.03), such that subjects with higher scores in NEAP had lower RMR and higher WC and WHR. We also observed that DAL (β= -0.02, 95% CI= -0.08 to0.03, P=0.08) and PRAL (β= -0.037, 95% CI= -1.05 to 0.03 P=0.07) were marginally associated with RMR.Conclusion:The results of the present study suggested that higher dietary acid load scores may be negatively associated with lower RMR, while directly associated with greater WC, WHR, DBP, and HOMA-IR.

NEAP index was inversely associated with RMR (β= -0.25, 95% CI=-0.1.5 to 2.08, P=0.02), and positively associated with WC (β= 1.009, 95% CI=-1.43 to 3.45, P=0.05) and WHR (β= 0.01, 95% CI= -0.01 to0.04, P=0.03), such that subjects with higher scores in NEAP had lower RMR and higher WC and WHR. We also observed that DAL (β= -0.02, 95% CI= -0.08 to0.03, P=0.08) and PRAL (β= -0.037, 95% CI= -1.05 to 0.03 P=0.07) were marginally associated with RMR.

Background: The advantages of laparoscopic left-sided hepatectomy (LLH) for treating hepatolithiasis in terms of the time to postoperative length of hospital stay (LOS), morbidity, long-term abdominal wall hernias, hospital costs, residual stone rate and recurrence of calculus have not been confirmed by a randomized controlled trial. The aim of this trial is to compare the safety and effectiveness of LLH to those of open left-sided hepatectomy (OLH) for the treatment of hepatolithiasis. Methods: Patients with hepatolithiasis eligible for left-sided hepatectomy will be recruited. The experimental design will produce two randomized arms (laparoscopic and open hepatectomy) at a 1:1 ratio and a prospective registry. All patients will undergo surgery in the setting of an enhanced recovery after surgery (ERAS) program. The prospective registry will be based on patients who cannot be randomized because of the explicit treatment preference of the patient or surgeon or because of ineligibility (not meeting the inclusion and exclusion criteria) for randomization in this trial. The primary outcome is the LOS. The secondary outcomes are percentage readmission, morbidity, mortality, hospital costs, long-term incidence of incisional hernias, residual stone rate and recurrence of calculus. It will be assumed that, in patients undergoing LLH, the length of hospital stay will be reduced by 1.3 days. A sample size of 44 patients in each randomization arm has been calculated as sufficient to detect a 1.3-day reduction in LOS (90% power and α = 0.05 (two-tailed)). The trial is a randomized controlled trial that will provide evidence for the merits of laparoscopic surgery in patients undergoing liver resection within an ERAS program. Discussion: Although the outcomes of LLH have been proven to be comparable to those of OLH in retrospective studies, the use of LLH remains restricted, partly due to the lack of short-and long-term informative RCTs pertaining to patients with hepatolithiasis in ERAS programs. To evaluate the surgical and long-term outcomes of LLH, we will perform a prospective RCT to compare LLH with OLH for hepatolithiasis within an ERAS program.Trial registration: ClinicalTrials.gov NCT03958825.

When an epidemic spreads into a population, it is often unpractical or impossible to have a continuous monitoring of all subjects involved. As an alternative, algorithmic solutions can be used to infer the state of the whole population from a limited amount of measures. We analyze the capability of deep neutral networks to solve this challenging task. Our proposed architecture is based on Graph Convolutional Neural Networks. As such it can reason on the effect of the underlying social network structure, which is recognized as the main component in the spreading of an epidemic. We test the proposed architecture with two scenarios modeled on the CoVid-19 pandemic: a generic homogeneous population, and a toy model of Boston metropolitan area.

Precipitation time series exhibit complex fluctuations and statistical changes. We investigate and forecast precipitation variations in South Korea from 1973 to 2019 using cyclostationary empirical orthogonal function (CSEOF) and regression methods. First, empirical orthogonal function (EOF) and CSEOF analyses are used to examine the periodic changes in the precipitation data. Then, the autoregressive moving average (ARMA) method is applied to the principal component (PC) time series derived from the EOF and CSEOF precipitation analyses. The fifteen leading EOF and CSEOF modes and their corresponding PC time series clearly reflect the spatial distribution and temporal evolution characteristics of the precipitation data. Based on the PC forecasts of the EOF and CSEOF models, the EOF-ARMA composite model and CSEOF-ARMA composite model are used to obtain quantitative precipitation forecasts. The comparison results show that both composite models have good performances and similar accuracies. However, the performance of the CSEOF-ARMA model is better than that of the EOF-ARMA model under various measurements. Therefore, the CSEOF-ARMA composite forecast model can be considered an efficient and feasible technology representing an analytical approach for precipitation forecasting in South Korea.

Introduction To evaluate the effects of combined therapy using intravitreal Aflibercept (IVA) and photodynamic therapy (PDT) on polypoidal choroidal vasculopathy related to pachychoroid disease (PPCV).Methods Patients with PPCV were treated with PDT combined with 3 IVA injections on a monthly basis, followed by pro re nata criteria. The 12-month follow-up consisted of multiple revaluations of visual acuity and SSOCT parameters of clinical activity.Results Nineteen eyes were included in the study; mean age was 65.5 years. Visual acuity improved after 12 months (0.35 ± 0.25 to 0.2 ± 0.20 logMAR, p = 0.005). Percentage of eyes with intraretinal and subretinal fluid reduced from baseline to the 12-month follow-up (from 52.6–10.5%, p = 0.12, and from 89.5–5.3% p = 0.0009, respectively). Central retinal and mean macular thicknesses reduced (258 ± 39.6 to 204.8 ± 38.8 µm p = 0.04 and 293.8 ± 32.1 to 248.1 ± 29.6 µm p = 0.017 respectively). Central choroidal and mean choroidal thicknesses also displayed a reduction (328.6 ± 54.9 to 289.8 ± 44.6 µm p = 0.001 and 314.5 ± 55.3 to 287.9 ± 47.6 µm p = 0.015 respectively). The mean number of injections was 4.6/year.Conclusion The results support the use of a combined therapy with Aflibercept and PDT in PPCV. This treatment would act in synergy, with anti-VEGF controlling exudation and PDT closing the aneurysmal vessel and reducing choroidal congestion.

Background: Dental caries is associated with Biological, behavioral, socioeconomic, and environmental factors; however, socioeconomic status is a distal determinant of dental caries development that modulates exposure to risk and protective factors. This study aimed to analyze the factors associated with the distribution and concentration of oral diseases in a population-based study in Brazil.Methods: This is a quantitative, analytical, cross-sectional study based on secondary data from the SB São Paulo 2015 epidemiological survey. A total of 17,560 subjects were included. The concentration of oral disease in the population was estimated by the oral disease burden (ODB) variable. The ODB consists of four components: dental caries; tooth loss; need for dental prosthesis and periodontal condition. Thus, the total score on the ODB could vary between 0 and 4, with the highest score indicating the worst possible situation. ODB was analyzed in multivariate negative binomial regression, and multivariate binary logistic regression analysis. The following demographic data were included as independent variables: age group, skin color, socioeconomic data, and family income.Results: ODB was present in 86.9% of the sample. Negative multivariate binomial regression showed a statistically significant relationship (p<0.005) between ODB and all variables analyzed (skin color, family income, education, OIDP results and age range). The adjusted multivariate binary logistic regression showed that the individuals most likely to have at least one component of ODB were nonwhite (25.5%), had a family income of up to R$ 1,500.00 / month (19.6%), had only completed primary education (19.1%), and reported that their oral health had an impact on their daily activities (57.6%). Elderly individuals were two times more likely than adolescents to have an ODB component.Conclusions: ODB is associated with factors related to social inequality. Adults and elderly individuals had the highest cumulative number of ODB components.

Backgound Impaired fasting glucose (IFG) is an invertible interim hyperglycemia period with an increasing risk of diabetes and related complications. Our study was designed to identify that the serum anion gap is related to the risk of progressing to IFG and diabetes. Methods We performed a prospective, population-based study among 1191 Chinese individuals aged 22-87 years who taken health examinations annually between 2006 and 2012 including clinical features and plasma metabolites. All of the participants had no history of diabetes or related chronic complications. We designed logistic regression analysis to examine the associations between clinical and metabolomic factors and the risk of developing to IFG or diabetes. Results Among them, 58 subjects whose fasting glucose were between 6.1 and 7 mmol/L were diagnosed as IFG or diabetes. After adjusting for age, gender, body mass index (BMI), low-density lipoprotein (LDL), high-density lipoprotein (HDL), alanine aminotransferase (ALT), aspartate aminotransferase (AST), systolic blood pressure (SBP), diastolic blood pressure (DBP), potassium and albumin at baseline, the participants in the upper tertiles of serum anion gap (SAG) are more likely to progress to IFG or diabetes than those in the lower tertiles. Receiver operating characteristic (ROC) curve analysis was used to predict incidence of IFG or diabetes. We found the optimal cutoff level for the anion gap was 13.76 mmol/L and the AUC (area under ROC curve) was 0.623. Conclusions Our data demonstrate that a higher SAG is associated with the risk of developing IFG or diabetes.
