Background
Recently, with the development of multidisciplinary treatment, the treatment outcomes of esophageal cancer (EC) have improved. However, despite advances in diagnostic imaging modalities, preoperative diagnosis of T4 EC is still difficult, and the prognosis of T4 EC remains very poor. In addition, the prognosis of surgical T4b EC (sT4b EC) after surgery remains unclear. In this study, we retrospectively reviewed sT4b EC.
Methods
We evaluated the clinical course of sT4b EC and compared palliative esophagectomy with R2 resection (PE group) with other procedures without esophagectomy (NE group) (e.g., only esophagostomy) for sT4b EC.
Results
Forty-seven patients with thoracic EC underwent R2 resection at our institution between January 2009 and December 2020. Thirty-four patients were in the PE group and 13 patients were in the NE group. The 2-year overall survival rate was 0% in the PE group and 20.2% in the NE group (p = 0.882). There was one case of long-term survival in the NE group that underwent surgery followed by definitive chemoradiation. Postoperative complications (Clavien–Dindo grade ≥3) were observed in 25 patients (73.5%) in the PE group and three patients (23.1%) in the NE group (p = 0.031). The median time to the initiation of postoperative treatment was 68.1 days in the PE group and 18.6 days in the NE group (p = 0191).
Conclusions
If EC is diagnosed as sT4b, palliative esophagectomy should be avoided because of the high complication rate and the lack of long-term survival.
Intensive Neurophysiological Rehabilitation System for Children with Cerebral Palsy: A Quasi-Randomized Controlled Trial
Authors: Kushnir Anna , Kachmar Oleh
Published: December 2022

Background. Recent research indicates that intensive rehabilitation tends to be effective for children with cerebral palsy (CP). Intensive Neurophysiological Rehabilitation System (INRS) is a multi-component approach that combines various interventions and addresses functional goals in different domains according to the International classification of functioning, disability, and health (ICF). This study aimed to examine the effectiveness of the INRS treatment in children with bilateral CP.
Methods. In this quasi-randomized controlled study, 48 children with spastic bilateral CP (age 5-12 years, GMFCS Levels I-IV, MACS Levels I-IV) were assigned to an experimental or control group in order they have been enrolled. The experimental group underwent INRS treatment and continued routine home treatment for four weeks. After the first evaluation, participants from the control group stayed on the waiting list for four weeks receiving home treatment and then starting the INRS treatment. Thereby, all participants were assessed three times. The primary outcome measure was a Gross Motor Function Measure 66 Item Set (GMFM). The secondary outcome measures included the Jebsen-Taylor Hand Function test, Box and Blocks test, ABILHAND-Kids Questionnaire, Self-care and Mobility domain of the Pediatric Evaluation of Disability Inventory, and the ankle dorsiflexion passive range of motion.
Results. There was a statistically significant increase in the GMFM score after the INRS treatment in both the experimental group (mean difference (MD) 2.0, P<0.01) and control group (MD 1.5, P<0.05), with a large size effect (partial eta squared (η2) =0.21 and η2=0.14). The mean difference between groups during the first study period was 2.89 points (p<0.01) in the GMFM score with a medium effect size (η2=0.12). Statistically significant superiority of the INRS treatment over home treatment was also obtained by Jebsen-Taylor Hand Function Test and the Box and Blocks Test in both dominant and non-dominant hands.
Conclusions. The study indicates that the INRS treatment can be beneficial for improving both gross motor functions and hand function in children with bilateral CP. Further longitudinal studies are required to evaluate the effects of the INRS treatment on the participation level of children with CP.
Trial registration: The study protocol was registered on ClinicalTrials.gov under the identifier: NCT04093180.

In this article, we presented the development of fully modular microfluidic flow cells for an electrochemical using 3D printing. The proposed devices are potential for electrochemical measurements using a small sample volume on a fully portable, reusable, simply fabricated, low-cost, PDMS-free, and leakage-free flow cell. This concept offers a simple, controllable sample over the conventional electrochemical platform with a three-electrode system, which requires a considerable volume of samples or a non-controllable drop cast method for sequential protocols. We demonstrated an easy alignment and lock, namely, click-and-fit modular microfluidics, for quick and easy assembly and disassembly of flow cell modules using magnetic force instead of the screw, polymer glue, or resin. Two microfluidic modules were presented using tube- and syringe-flow cells (TFC and SFC) to integrate the screen-printed carbon electrodes (SPCE) in the electrochemical sensor. The proof-of-concept of the integrated sensor-microfluidic platforms was conducted under cyclic voltammetry using a tiny volume of a ferricyanide redox probe at only ~50 µL, differential pulse voltammetry, and square wave voltammetry. Implementing the proposed click-and-fit microfluidic modules in electrochemical detection achieves higher current peaks than droplet measurements. These flow cell modules are promising for biosensing applications using a small volume of physiological fluid samples.
Chinese quantifier scope, concord, and Lexical Resource Semantics
Authors: Niu Jingcheng , Kang Xinyu , Hohmann Pascal , Penn Gerlad
Published: December 2022

This paper considers Chinese quantifier scope, an important, outstanding
area of Chinese linguistics. In particular, there are two open questions on the
subject: (1) the guiding principles that determine (a) the scopal
readings of quantifiers and (b) the sometimes mandatory co-occurrence of the
universal quantifier mei (every) and the universal
adverb dou, and (2) the semantic functions of mei and
dou and their connection to the co-occurrence of these words.

We reappraise three prior accounts of these subjects, reason through their
consequences on some exemplary data, offer a new explanation based upon
concord, a mechanism that is commonplace in many languages, and formulate it in
lexical resource semantics (LRS). We use two principles adapted from
Richter and Sailer's (2004) analysis of negative concord,
expanded with a new quantifier order constraint to generate a
coherent answer to the two aforementioned questions.
Exogeneity of the circaseptan mood rhythm and its relation to the working week

Published: December 2022

Previous longitudinal studies of mood showed that mood displays a circaseptan (weekly) rhythm, reaching its peaks during weekends and falling during the working week. These studies stirred numerous debates about whether the circaseptan nature of the mood is determined culturally or biologically. The goal of the present study was to determine how the division of the week on the working week and the weekend impacts mood. A sample of students completed the shortened version of the PANAS-X questionnaire each day throughout July (working week and the weekend not separated) and November (working week and the weekend separated). Cosinor rhythmometry was used to analyze the data. As in previous research, a circaseptan mood rhythm was detected in November. However, a circaseptan rhythm was not detected in July - a circasemilunar rhythm was detected instead. These results suggest that the division of the week on the working week and the weekend has a great impact on mood and that more longitudinal studies of this type are needed to better understand this relationship.
Economic growth and its relationship with the macroeconomic factors: An analysis of Oman
Authors: Khan Uzma , Mohammad Khan Aarif , A. Siddiqi Nahid
Published: December 2022

This study determines Oman’s most important macroeconomic factors between 1990 and 2019. The ARDL bound test findings for co-integration show that both long and short runs exist. The error-correcting mechanism further states that when the divergence from long-run equilibrium is rectified at an adaptation speed of 78.9%, it signals an inversion to a long-run stable state. In response to a change in the previous year’s economic growth, the final consumption expenditure indicates a rise of 0.472; the gross fixed capital formation and export indicate hikes of 0.149 and 0.358 at a 1% significance level. Additionally, the findings of co-integration regression using fully modified ordinary least square (FMOLS), dynamic ordinary least square (DOLS), and canonical co-integration regression (CCR) were used to strengthen and validate the results that export ranks first in Oman, followed by final consumption spending. Therefore, export, gross fixed capital formation, and final consumption expenditure are vital macroeconomic elements supporting Oman’s economic development.
The Evolution of Violence Structures in Sports: From Colonialism to Asian-Oriented Capitalism
Authors: Dudnik Elizaveta
Published: December 2022

The author adopted the postcolonial perspective to analyze how sport has affected the destruction of violence structures, the emancipation, and the voice of subalterns since the decolonization. Having summarized the imperial sports policy, the article introduces 4 major trends in sports after decolonization. Nationalization is described through the prism of Indonesian badminton, Moroccan football, and petanque in Pondicherry. Integration is illustrated by the participation of former colonies in the Olympic Movement, world football, and IOC statistics. Commercialization is exemplified by the growing influence of new actors, i.e., non-traditional states, non-governmental organizations, multinational companies and by the migration of African footballers, Indonesian badminton players and rugby players from Oceania. The rise of Asian countries is revealed by means of the analysis of rankings of the highest-paid female athletes and leading sports manufacturers, LPGA Tour statistics on players’ origins, the geography of international tournaments, and the case of subaltern athlete P. V. Sindhu. The researcher concludes that the growing number and the changing nature of violence structures keeps subaltern athletes in a dependent and vulnerable position, forcing them to follow the rules set by longstanding and emerging centers of power, both politically and economically.

Socio-Economic Effects of Agricultural Holdings in Rural Areas of Novosibirsk Region: Indicators and Projection of Their Expression
Authors: Kondratev Mikhail
Published: December 2022

The ongoing socio-economic transformations have a significant impact on global food security and expose the problem of access to quality food for different population groups. In order to intensify food production, public institutions support large infrastructure projects in the agricultural sector and expand large vertically-integrated entities into rural areas, including regions with low agricultural development. A thorough analysis of negative experience in agricultural holdings could prevent the implicit degradation of the rural territories which they strive to support. The author developed a systematic multistage methodological approach to assessing the socio-economic effects of agricultural holdings. The method was tested in the Maslyanino municipal district of the Novosibirsk Region. The article introduces a matrix of potential socio-economic effects from the activities of agricultural holdings and a list of indicators to assess their expression. The study used such methods as description, classification, economic-mathematical modeling, trend analysis, analysis of financial coefficients, factor analysis, adaptive short-term forecasting, and formalization. The new methodological approach can be used to design scenarios of rural development by agricultural holdings, as well as to promote their positive socio-economic effects.
Zero additional maintenance stormwater biofilters: from laboratory testing to field implementation
Authors: Prodanovic Veljko , Hatt Belinda , Fowdar Harsha , Al-Ameri Mohammed , Deletic Ana
Published: December 2022

Stormwater biofilters are one of the most widely used nature-based solutions for urban water management. In the last 20 years, biofilters have been extensively studied for their pollutant removal performance; however, their application in the field is limited by high maintenance requirements. In this work, we propose the concept of zero additional maintenance (ZAM) biofilters as a solution to this challenge. To understand the design and operation of ZAM biofilters, a three-stage research programme was conducted to (i) examine filter media configurations that could protect against surface clogging, (ii) test the pollutant removal performance of a variety of lawn grasses, and (iii) validate the laboratory findings through field monitoring. The results showed that a protective filter media layer delayed the onset of clogging. Five lawn grasses – Kenda Kikuyu, Empire Zoysia, Santa Ana Couch, Village Green Kikuyu and Palmetto Soft Leaf Buffalo – were found to effectively reduce nitrogen concentrations and meet other local pollution reduction requirements. Monitoring of three field-scale ZAM biofilters confirmed their high nutrient and heavy metal removal performance. Overall, the findings of these three studies confirm the potential for well-designed ZAM biofilters to achieve stormwater management requirements with no additional maintenance compared with standard street landscaping.

This study conveys how to learn with digital media so students can easily understand the material presented independently. The research aims to create new learning innovations through digital audio-visual media easily accessible via mobile phones. Teaching media is made as a barcode that can be scanned and then pasted into the teaching material book. Audio-visual material can then be displayed on the topics discussed in the textbook. Students can easily understand the material because digital media can be explained in detail and completely about the material in student textbooks. The approach is carried out through the local wisdom of Sad Kerti Loka Bali in the Jagat Kertih section, which means glorifying the human environment so that students can adapt the teaching materials. The method used in this research is the Qualitative Method. The design process is carried out in three stages: pre-production, production, and post-production. In testing, in the first stage, students were taught conventional face-to-face methods. Then in the second stage, learning was carried out by adding digital material and being observed. Tests were carried out on early childhood students, teachers as material experts, and visual communication designers as media experts.

Thinking Transindividuality along the Spinoza-Marx Encounter: A Conversation
Authors: Wiggers Bram , Read Jason
Published: December 2022

Ever since the publication of Read’s The Politics of Transindividuality (2015), the academic interest in transindividuality has steadily mounted. In this conversation, Bram Wiggers and Jason Read discuss the current state of affairs around the concept of transindividuality. The conversation begins with a definition of transindividuality and discusses what sets the term apart from other philosophies of social individuation. Having defined the concept of transindividuality, the conversation then engages with the question of how transindividuality can be adopted as a means of social-political critique. First, Bram and Jason discuss how transindividuality is evoked but not explicitly mentioned in the social-political critiques of Spinoza and Marx. Secondly, the conversation takes up the social-political critiques of Paolo Virno and Bernard Stiegler who make explicit use of transindividuality. Central to the later parts of the conversation is the complicated interrelation between the political and economic domains of individuation, as well as the tendency of collective modes of representation to be effaced and obscured by (neoliberal) individualism and the post-Fordist conditions of labor. Overall, the conversation highlights the relevance of transindividuality for social-political philosophical critique.

Высокая подвижность дырок в дельта-легированных бором слоях алмаза: почему она до сих пор не достигнута и как ее можно достичь
Authors: Кукушкин В.А.
Published: December 2022

Рассчитаны параметры нанометровых delta-легированных бором слоев в алмазе, необходимые для достижения высоких проводимости и подвижности дырок. Концентрация бора в таких слоях должна быть достаточной для фазового перехода изолятор--металл, приводящего к металлическому типу проводимости. Показано, что учет сдвига энергии края валентной зоны из-за присутствия ионизованных атомов бора вызывает значительное углубление потенциальной ямы, образованной delta-легированным слоем для дырок. Это приводит к гораздо более сильному ограничению пространственного распределения последних, чем ожидалось ранее. В итоге предсказано, что значительное увеличение подвижности дырок, вызванное их делокализацией, может быть достигнуто, если толщина металлического delta-легированного слоя порядка и меньше 0.5 нм и степень компенсации не превышает 42%. Ключевые слова: delta-легированные слои, наноструктуры, осажденные из газовой фазы алмазные пленки, подвижность дырок, фазовый переход изолятор--металл.

Упругие свойства B2-NiAl с добавлением W: исследование из первых принципов
Authors: Пономарева А.В.
Published: December 2022

The effect of tungsten alloying on the elastic properties of B2 NiAl at low-temperature and high-temperature distribution of W atoms on sublattices. By means of the exact muffin-tin orbitals method in conjunction with the coherent potential approximation, the constants C11, C12, C44, Young's modulus E, shear modulus G, Cauchy pressure values, G/B ratios are calculated. Using phenomenological criteria of the correlation between ductility and elastic properties of solution phases, it has been shown that the addition of tungsten could yield improved ductility for B2 NiAl in both types of alloys. It is established that with the high-temperature distribution of W atoms on the Al sublattice, there is a loss of mechanical stability and a decrease in mechanical properties with increasing W concentration. In alloys with a low–temperature distribution of tungsten atoms between Al and Ni sites a unique combination of properties occurs: in addition to the ductility enhancement, a simultaneous increase of the elastic constants C44 and C11, shear modulus G, Young modulus E with increasing W content is observed. The differences in the behavior of elastic constants in alloys with different types of tungsten distribution on NiAl sublattices are analyzed by calculating the density of electronic states.

The relationship between sp^2/sp^3 hybridizations ratio of atomic bonds in diamond-like carbon (DLC) and its electrical resistivity for coatings with a thickness in the range 22-70 nm prepared by vacuum arc deposition on silicon substrate of the SHB-8 brand has been established.
It is established, that an increase in the coating thickness from 22 to 70 nm is accompanied by a decrease in the specific transverse electrical resistance of samples from 17 to 2 GOhm·m. This effect is explained by an increase in the proportion of carbon atoms with sp^2 hybridization of electronic orbitals from 86 to 91%, which leads to the appearance of an additional number of π-bonds.
A mathematical model, describing the spatial distribution of current when measuring transverse I-V characteristic, has been developed. The results obtained will be useful in creating resistive layers on the electrodes of gas-discharge detectors of charged particle to limit the amount of current in the event of rare spark discharges inside them caused by the registration of random highly ionizing particles.

In this paper, the effect of the orientational stretching rate on the piezoelectric properties and structure of the vinylidene fluoride-tetrafluoroethylene P(VDF-TFE) copolymer was studied. A relationship in the formation of the electret and piezoelectric states in P(VDF-TFE) has been established. The parameters of electrically active defects involved in the polarization process and determining the stability of the electret and, as a consequence, the piezoelectric states in P(VDF-TFE) are calculated.

Polydiphenylenephthalide (PDP) belongs to the class of organic dielectrics, which exhibit electric conductive properties when an external electrostatic field and/or mechanical stress are applied. In this work, the transport properties of thin-film layered lead–PDP–lead structures were experimental-ly studied in a wide temperature range. At sufficiently high temperatures, the volt–ampere depend-ences are satisfactorily described in terms of the injection model of currents limited by the space charge. At temperatures below ~7.5 K, a number of samples exhibit features that can be explained by the effect of induced superconductivity in a thin film of a conducting polymer enclosed between two massive superconductors (lead).

The calculated ratios of the signal of backscattered electrons for multilayer nanostructures are derived depending on the energy of probing electrons and the composition of multicomponent samples. From experimentally measured signals and calculated ratios, not only thicknesses, but also, for the first time, depths of occurrence of local microheterogeneities of three-dimensional nanostructures were determined. The studies were carried out by a non-destructive method for detecting backscattered electrons in a scanning electron microscope.

Using the averaged equations supplemented with 3D particle-in-cells simulation methods, we study the frequency multiplication regime in high-current relativistic gyrotron. We show that the ratio between the output power of the higher (fifth or sixth) harmonics and that on the fundamenta cyclotron resonance may be of about 0.1-0.3%. Accordingly, the nonlinear transformation coefficient as several orders higher than the values achievable in gyrotrons with weakly relativistic electron beams.

Technology of obtaining graphene by means of ultrasonic dispersion of thermally expanded graphite in the presence of a surface-active polymer Nafion is presented. The technology makes it possible to obtain large amounts of low-layer (1-3 layers) graphene in a relatively short time. An approach to control the dispersion process based on UV spectroscopy of dispersions is described. A mechanism is proposed for the effect of a surface-active polymer on the production of low-layer graphene by ultrasonic dispersion.
Estimation of the Return Periods in Hydrology
Authors: Lefebvre Mario
Published: December 2022

A filtered Poisson process is proposed as a model for river flows. With the help of real-life data, the model parameters are estimated. Mathematical formulae are derived in order to estimate the various return periods of the river. An application to two rivers shows that the point estimates are very close to the corresponding values computed by hydrologists, based on historical data. Moreover, by modifying the values of the parameters in the model, we can see the potential effects of climate change on the return periods.

BACKGROUND

Open access (OA) publishing represents an exciting opportunity to facilitate the dissemination of scientific information to global audiences. However, OA publishing is often associated with significant article processing charges (APCs) for authors, which may thus serve as a barrier to publication.

OBJECTIVE

In this observational cohort study, we aimed to characterize the landscape of OA publishing in oncology and, further, identify characteristics of oncology journals that are predictive of APCs.

METHODS

We identified oncology journals using the SCImago Journal & Country Rank database. All journals with an OA publication option and APC data openly available were included. We searched journal websites and tabulated journal characteristics, including APC amount (in US dollars), OA model (hybrid vs full), 2-year impact factor (IF), H-index, number of citable documents, modality/treatment specific (if applicable), and continent of origin. All APCs were converted to US-dollar equivalents for final analyses. Selecting variables with significant associations in the univariable analysis, we generated a multiple regression model to identify journal characteristics independently associated with OA APC amount. An audit of a random 10% sample of the data was independently performed by 2 authors to ensure data accuracy, precision, and reproducibility.

RESULTS

Of 367 oncology journals screened, 251 met the final inclusion criteria. The median APC was US $2957 (IQR 1958-3450). The majority of journals (n=156, 62%) adopted the hybrid OA publication model and were based in Europe (n=119, 47%) or North America (n=87, 35%). The median (IQR) APC for all journals was US $2957 (1958-3540). Twenty-five (10%) journals had APCs greater than US $4000. There were 10 (4%) journals that offered OA publication with no publication charge. Univariable testing showed that journals with a greater number of citable documents (P<.001), higher 2-year IF (P<.001), higher H-index (P<.001), and those using the hybrid OA model (P<.001), or originating in Europe or North America (P<.001) tended to have higher APCs. In our multivariable model, the number of citable documents (β=US $367, SD US $133; P=.006), 2-year IF (US $1144, SD US $177; P<.001), hybrid OA publishing model (US $991, SD US $189; P<.001), and North American origin (US $838, SD US $186; P<.001) persisted as significant predictors of processing charges.

CONCLUSIONS

OA publication costs are greater in oncology journals that publish more citable articles, use the hybrid OA model, have a higher IF, and are based in North America or Europe. These findings may inform targeted action to help the oncology community fully appreciate the benefits of open science.
Moving Beyond Handoffs: Optimizing Decision Support Technology to Reduce Medication Timing Errors for Operative Patients. A Prospective Interventional Study (Preprint)
Authors: Williams Jessica
Published: December 2022

BACKGROUND

Medication administration in the Operating Room presents a unique and heightened set of patient safety challenges due to a combination of design features of modern electronic health records (EHRs) and medication administration workflows common among anesthesiologists. Patients transferring from one area to another within a hospital system, particularly perioperative patients, are at increased risk for medication dose timing errors.

OBJECTIVE

A novel set of decision-support tools incorporating physician-centered design and fulfilling usability heuristics were developed for the operative suite to reduce dose timing errors for targeted medications. We sought to improve the visibility of prior doses of medications and related medications to inform anesthesia providers of relevant recent doses without increasing alert fatigue.

METHODS

Perioperative medication timing errors rates and anesthesia provider perceptions of EHR safety utility and usability were assessed before and after the implementation of electronic health record display reconfigurations and alerts in the operative environment.

RESULTS

In an interrupted time series analysis examining dose timing error rates for patients receiving nonsteroidal anti-inflammatory drug (NSAID) medications in the operating room, the cumulative incidence rate fell from a baseline of .56 (2014 – 16, 15/106) to .28 (2017 – 21, 27/375) after the introduction of novel visibility and alerting tools. Eighty-eight percent of anesthesia providers rated the newly introduced tools as useful in preventing errors, with 55% providers reporting less alert fatigue. Without exception, anesthesia provider respondents described the new tools as usable, effective patient safety improvements. All anesthesia providers reported increased confidence in the safety design of the EHR system to help reduce medication timing errors.

CONCLUSIONS

Medication decision support functionality for anesthesia patient care is an important, under-developed, opportunity for improving patient safety and provider satisfaction. The alerts developed for the anesthesia team achieved meaningful reductions in timing errors, and were overwhelmingly well-received by anesthesiology providers, who endorsed decreased alert fatigue and increased trust in EHR system safeguards.
