Rozvíjanie zručnosti počúvania s porozumením vo výučbe odborného nemeckého jazyka pre stredne pokročilých na Ekonomickej univerzite v Bratislave
Authors: Kucharová Jana , Kunovská Ingrid 
Published: May 2021

Komunikatívna výučba cudzích jazykov si vyžaduje rozvíjať u učiacich sa všetky jazykové zručnosti a kompetencie s cieľom nadobudnúť čo najvyššiu komunikatívnu kompetenciu v cieľovom jazyku. Platí to i pre výučbu odborného jazyka. Na jednotlivých fakultách Ekonomickej univerzity v Bratislave absolvujú študenti dvoj- až trojsemestrálne kurzy odborného jazyka v dvoch zvolených cudzích jazykoch. Nemecký jazyk je po angličtine druhým najpočetnejšie zastúpeným cudzím jazykom v rámci výučby na našej univerzite. Študenti si nemčinu vyberajú predovšetkým ako druhý cudzí jazyk. Úroveň jeho ovládania je preto nižšia, v rámci týchto kurzov dosahuje maximálne úroveň B1 podľa Spoločného európskeho referenčného rámca pre jazyky. O to viac je potrebné ponúknuť študentom možnosť zlepšovať ich komunikačné schopnosti pomocou rôznych metód, foriem i prostriedkov výučby a ukázať im, ako sa jazykovej výučbe môžu venovať aj samostatne, po absolvovaní kurzov odborného nemeckého jazyka v rámci ich vysokoškolského štúdia. Preto sme sa v rámci projektu KEGA (KEGA 005EU-4/2018) rozhodli zaoberať problematikou rozvíjania receptívnej jazykovej zručnosti počúvania s porozumením v rámci výučby odborného nemeckého jazyka pre stredne pokročilých na jednotlivých fakultách Ekonomickej univerzity v Bratislave. Ako prostriedok na rozvíjanie počúvania s porozumením sme si na už existujúcej platforme vytvorili vlastný podcast. Použili sme ho ako médium, prostredníctvom ktorého sme postupne študentom zverejňovali nahrávky s textami na počúvanie s porozumením a rôzne typy úloh k nim. V príspevku prezentujeme čiastkové výsledky našej doterajšej práce a formulujeme východiská pre ďalšie, ešte hlbšie skúmanie zvolenej problematiky.
La imagen del Otro chino a través de las portadas: un estudio empírico basado en un corpus de traducciones de narrativa china contemporánea al castellano y al catalán (1949-2019)
Authors: An Tsun-Wei 
Published: May 2021

Este trabajo se centra en revelar la imagen del Otro chino que se puede encontrar en las portadas de la narrativa china contemporánea traducidas al castellano y/o al catalán que se publicaron en España desde 1949 hasta 2019.
La traducción, desde la antigüedad, ha desempeñado un papel clave en la comunicación entre países y culturas. En este proceso, aparte del texto, los paratextos también se encargan de transmitir información y conocimientos socio-culturales de otras literaturas. Además, ofrecen un espacio aún más libre para que los agentes mediadores desplieguen su ideología con el fin de producir una imagen que pueda acercarse más a las expectativas de los lectores receptores.
Las 197 portadas recopiladas en nuestro corpus revelan que los paratextos han servido como plataforma valiosa para establecer la imagen del Otro chino en España un tanto distorsionada, ya que, basándonos en un análisis cuantitativo y cualitativo, apreciamos una discordancia temporal entre los modelos chinos que se presentan en las portadas y los que subyacen en el contenido de la obra. Del mismo modo, en este trabajo también encontramos un uso incoherente de los sinogramas en las portadas, que se convierten en una marca cultural con el fin de subrayar el carácter exótico de la cultura china.
En definitiva, a través del análisis de las portadas de las traducciones de la narrativa china contemporánea al castellano y al catalán, confirmamos que la imagen de los chinos ha sido parcialmente manipulada, mostrándose un estereotipo estancado en la antigüedad, con un uso más predominante del sexo femenino y recurriendo a tópicos exotizantes como la escritura.
Ensemble modeling of watershed‐scale hydrologic effects of short‐rotation woody crop production
Authors: Vache Kellie , Meles Menberu Bitew , Griffiths Natalie A , Jackson C Rhett 
Published: May 2021

AbstractShort‐rotation woody crop (SRWC) production involves a set of silvicultural practices that aim to produce large volumes of biomass over relatively short time frames. The area over which these practices are employed is likely to increase in the coming decades as the demand for bioenergy increases, but the potential effects of this change in land management, including the hydrologic effects, are largely unknown. Here we outline the results from an ensemble modeling study that was developed to forecast the range of potential hydrological responses to the implementation of SRWC production over areas that are large (>1000 ha) relative to the size of individual clearcuts. The three models, SWAT, MIKE‐SHE, and Envision‐SRS, a physically based model designed to represent watersheds with dynamic land cover, represent a range of simulation tools that include hydrological response to landcover change. Results suggest that SRWC production will affect the hydrologic balance, primarily through changes in the volume of transpired water associated with the rapidly growing young stands. In particular, average annual actual evapotranspiration (ET) rates tend to decline under SRWC production in response to the less mature vegetation. These reductions in ET are balanced in the hydrological cycle through elevated groundwater recharge, expressed in the model results as elevated annual stream discharge. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd
Ultrafast Photo‐ion Probing of the Ring‐Opening Process in Trans‐Stilbene Oxide

Published: May 2021

AbstractThe ultrafast photo‐induced ring opening of the oxirane derivative trans‐stilbene oxide has been studied through the use of ultrafast UV/UV pump‐probe spectroscopy by using photo‐ion detection. Single‐ and multiphoton probe paths and final states were identified through comparisons between UV power studies and synchrotron‐based vacuum ultraviolet (VUV) single‐photon ionization studies. Three major time‐dependent features of the parent ion (sub‐450 fs decay, (1.5±0.2) ps, and >100 ps) were observed. These decays are discussed in conjunction with the primary ring‐opening mechanism of stilbene oxide, which occurs through C−C dissociation in the oxirane ring. The appearance of fragments relating to the masses of dehydrogenated diphenylmethane (167 amu) and dehydrogenated methylbenzene (90 amu) were also investigated. The appearance of the 167 amu fragment could suggest an alternative ultrafast ring‐opening pathway via the dissociation of one of the C−O bonds within the oxirane ring.
Spatial distribution and driving factors determining local food and feed self‐sufficiency in the eastern regions of China

Published: May 2021

AbstractAchieving food and feed self‐sufficiency is important for both China and the world. While China's food self‐sufficiency has been examined at the national and provincial levels, few studies consider lower administrative levels or different food and feed items. This study quantifies self‐sufficiency in the eastern regions of China and examines correlations with agronomic (arable area, yield, fertilizer input, and machinery power) and socioeconomic (population density, gross domestic product [GDP]) variables at the local level, which are related to the interactions of the Sustainable Development Goals. We calculated food and feed balances, and checked correlations across and within regions grouped by population density levels between production, balance indices, and other agronomic and socioeconomic variables. The results showed that most regions can achieve self‐sufficiency in cereals, vegetables, and meat. Regarding eggs and maize, there was self‐sufficiency in the north but deficiency in the south. Nearly all regions demonstrated extreme shortages of milk and soybeans. The results also showed a positive correlation between the production of some food commodities and the population in eastern regions of China, demonstrating that the aim of achieving food self‐sufficiency at the local level is pursued. For cereals, vegetables, and maize, the yield and arable land per capita were positive factors for self‐sufficiency, while GDP per capita was a negative factor for cereals, meat, and maize. Various factors have different impacts on the food and feed self‐sufficiency of regions based on population density. Protecting arable land by rural revitalization and mitigating urban sprawl can retain food and feed self‐sufficiency in large cities. This study outlines important implications for policymakers seeking to achieve food and feed self‐sufficiency in China.

AbstractTris (1,3‐dichloro‐2‐propyl) phosphate (TDCIPP) is one of the most commonly used organophosphorus flame retardants. Immuno‐toxicity induced by TDCIPP is becoming of increasing concern. However, effects of TDCIPP on immune cells and mechanisms resulting in those effects are poorly understood. In this study, it was determined, for the first time, by use of isobaric tags for relative and absolute quantification (iTRAQ) based proteomic techniques expression of global proteins in RAW264.7 cells exposed to 10 μM TDCIPP. A total of 180 significantly differentially expressed proteins (DEPs) were identified. Of these, 127 were up‐regulated and 53 were down‐regulated. The DEPs associated with toxic effects of TDCIPP were then screened by use of Gene Ontology and the Kyoto Encyclopedia of Genes and Genomes for enrichment analysis. Results showed that these DEPs were involved in a number of pathways including apoptosis, DNA damage, cell cycle arrest, immune‐toxicity, and signaling pathways, such as the Toll‐like receptor, PPAR and p53 signaling pathways. The complex regulatory relationships between different DEPs, which might play an important role in cell death were also observed in the form of a protein–protein interaction network. Meanwhile, mitochondrial membrane potential (MMP) in RAW264.7 cells after TDCIPP treatment was also analyzed, the collapse of the MMP was speculated to play an important role in TDCIPP induced apoptosis. Moreover, some of the important regulator proteins discovered in this study, such as Chk1, Aurora A, would provide novel insight into the molecular mechanisms involved in toxic responses to TDCIPP.

Objectives/HypothesisSevere acute respiratory syndrome coronavirus 2 (SARSCoV‐2) is transmitted by droplet as well as airborne infection. Surgical patients are vulnerable to the infection during their hospital admission. Some surgical procedures are classified as aerosol generating (AGP).Study DesignRetrospective observational study of four specialties associates with known AGP's during the 4 months of the first wave of UK COVID‐19 epidermic to identify post‐surgical cross‐infection with SARSCoV‐2 within 14 days of a procedure.MethodsRetrospective observational study in a tertiary healthcare center of four specialties associates with known AGP's during the 4 months of the first wave of UK COVID‐19 epidermic to identify post‐surgical cross‐infection with SARSCoV‐2 within 14 days of a procedure.ResultsThere were 3,410 procedures reported during this period. The overall cross‐infection rate from tested patients was 1.3% (4 patients), that is, 0.11% of all operations over 4 months. Ear, nose, and throat carried slightly higher rate of infection (0.4%) than gastroenterology (0.08%). The mortality rate was 0.3% (one gastroenterology patient from 304 positive cases) compared to 0% if surgery performed after recovery from SARSCoV‐2 and 37.5% when surgery was conducted during the incubation period of the disease. Routine preoperative rapid screening tests and self‐isolation are crucial to avoid the risk of cross‐infection. Patients with underlying malignancy or receiving chemotherapy were more prone to pulmonary complications and mortality.ConclusionThe risk of SARS‐COV‐2 cross‐infection after surgical procedure is very low. Preoperative screening and self‐isolation together with personal protective measures should be in place to minimize the cross‐infection.Level of Evidence4 Laryngoscope, 131:E2749–E2754, 2021
Patient‐to‐robot registration: The fate of robot‐assisted stereotaxy

Published: May 2021

AbstractBackgroundRobot‐assisted stereotaxy (RAS) promises higher stereotactic accuracy (SA) and time efficiency (TE) than frame‐based stereotaxy. However, both aspects are attributed to the problem of patient‐to‐robot registration.ObjectiveTo examine different registration techniques regarding their SA and TE.MethodsThis study enrolled 57 patients undergoing RAS with bone fiducial registration (BFR) or laser surface registration (LSR). SA was measured by the entry point error (EPE). Additionally, predictors of SA (registration error [RegE], distance‐to‐registration plane [DTC]) and TE (imaging, skin‐to‐skin) were assessed.ResultsThe mean SA was 1.0 ± 0.8 mm. BFR increased SA by reducing RegE and DTC. In LSR, EPE depended on DTC (face and forehead) with highest accuracy for DTC ≤100 mm. CT‐based LSR exerted a higher SA than MR‐based LSR. In BFR, TE was confined by the additional imaging.ConclusionEvery registration technique counteracts one of the promises of RAS. New solutions are needed to increase the acceptance of RAS in neurosurgery.
Interface Structure and Dynamics in Polymer‐Nanoparticle Hybrids: A Review on Molecular Mechanisms Underlying the Improved Interfaces
Authors: Sattar Mohammad Abdul 
Published: May 2021

AbstractIn a nano‐assembly of soft polymer chains and hard filler nanoparticles (NPs), the intermolecular interactions at the polymer‐filler interface lead to variations in viscoelastic properties in the vicinity of the NP surface. However, unravelling the molecular parameters controlling the entropic and enthalpic interactions, including polymer chain conformation, dynamics, dispersion mechanisms and confinement effects across the interfacial region, has been remote and challenging. Even though the polymer‘s molecular structure and the NPs surface chemistry contribute to these interfacial interactions, the underlying mechanism behind the enhanced dynamic‐mechanical performance is still a hot topic of debate. By controlling the chemistry of NPs and polymer matrix in model nanocomposites, many efforts have been made in elucidating the physical origin of the structure and dynamics of the interfacial polymer layer with estimates varying from 1 to 10 nm around the spherical NPs. Therefore, understanding the interface structure and dynamics influenced by polymer‐NP interaction is of great technological importance. In this article, the latest polymer‐particle interface literature developments are reviewed where computational simulations, calorimetry, and dielectric spectroscopy studies have been used to examine the constraints levied by the interface structure on segmental relaxation dynamics of polymer chains in the vicinity of NP surface.

AbstractThe exploration of hybrid molecules for targeting various diseases represents a highly promising approach which has showcased significant momentum worldwide, in the last two decades. Diversely substituted quinoline scaffolds present in naturally occurring bioactive compounds, signify their role in various biological processes and stimulated the research developments around it, for diverse therapeutic applications. With the ongoing search for suitable pharmacophores, the quinoline derivatives have emerged as versatile compounds possessing significant and broad spectrum of biological activities. Further, conjugation of quinoline with other bioactive heterocycles containing oxygen yielded hybrid organic frameworks with improved therapeutic profile leading to an emerging paradigm and tremendous growth in the contemporary drug discovery regime. The synthesis of these hybrid skeletons with high efficiency still remains the most strenuous task and a lot of research work is being performed in this direction. In the present article, we have reviewed the synthetic protocols leading to quinoline‐oxygen heterocycle hybrids and also highlighted the systematic and biological assessment of developed pharmacophores.

AbstractTwo 20‐membered macrocyclic complexes, [Cu2L1(ClO4)2] (1) and [Ni2L2(ClO4)2(H2O)2][Cu2L2(H2O)2](ClO4)2 (2) (where H2L1 and H2L2 are the condensation products of ɑ, ω‐amine with 3,3′‐((propane‐1,3‐diylbis(azanylylidene)) bis(methanylylidene))bis(5‐X‐2‐hydroxybenzaldehyde)), have been synthesized and characterized by X‐ray diffractions single crystal structure analysis. The results indicated that the structures of two complexes are symmetrical. In complex 1, the geometry around each copper(II) center is a slightly distorted square pyramidal with structural index parameter τ=0.062 for Cu1 and 0.067 for Cu2, the distance between Cu1 and Cu2 is 3.1075 Å. Complex 2 contains two similar macrocyclic units (A and B), the metal‐metal distances in A and B are 3.0760 and 3.0922 Å, respectively. The interaction between the complexes and calf thymus (CT‐DNA) were investigated by spectroscopic method. The phosphate hydrolysis activities of the complexes were examined using 4‐nitrophenyl phosphate disodium salt hexahydrate (pNPP) as the substrate. The corresponding catalytic rate constant (kcat) at pH 7.2 are 2.14×10−5 and 2.85×10−5 s−1, respectively, 104 times faster than the spontaneous hydrolysis of phosphate monoester.
Surgical management and long‐term outcome of complete penoscrotal transposition in a dog

Published: May 2021

AbstractA 1.66 kg, approximately 4‐week‐old, intact male canine mixed breed was evaluated for 'urinating backward'. Genitourinary evaluation revealed that the preputial opening was not patent, and his penis traversed in a caudal direction, exiting in the perineum caudal to the scrotum. Testicles were not palpated at this time. Over an 8‐week period as the dog continued to undergo musculoskeletal maturation, the scrotum would become intermittently infected, and the dermal exit site of the penis constricted the penis resulting in marked paraphimosis. En bloc preputial resection, phallectomy, scrotal ablation, castration and perineal urethrostomy (PU) were performed to correct this abnormality. Histopathology confirmed only a left testicle within the scrotum. Abdominal imaging and anti‐Mullerian hormone assay confirmed right testicular cryptorchidism. Two months after the initial surgery, successful removal of the retained right testicle was performed, and the dog was reported to be urinating through the PU stoma normally. This is the first reported case of penoscrotal transposition in a dog.

AbstractThis report describes the successful treatment of a chronic diaphragmatic hernia in a 2.5‐year‐old crossbred gelding. The tear remained unidentified until colic signs and dyspnoea appeared. In this case, an unconventional surgical approach was used. Based on the clinical findings, diaphragmatic herniation with non‐strangulating large intestinal involvement was diagnosed. From the ventral midline approach, a diaphragmatic tear with a diameter of 20 cm in the left ventral area was found together with a fractured 10th rib. Repositioning of the large colon was unsuccessful through the ventral midline approach, therefore lateral thoracotomy via rib resection was performed without closing the ventral midline incision. The simultaneous laparotomy with thoracotomy can be a useful approach in the treatment of diaphragmatic hernias when the tear is located ventrally. Advantages of the described surgical technique were easier reposition of the herniated intestine and good access to close the diaphragmatic tear, and disadvantage was the longer surgical time.

Published: May 2021

Abstract
We compute the top quark contribution to the two-loop amplitude for on-shell Z boson pair production in gluon fusion, gg → ZZ. Exact dependence on the top quark mass is retained. For each phase space point the integral reduction is performed numerically and the master integrals are evaluated using the auxiliary mass flow method, allowing fast computation of the amplitude with very high precision.

Abstract
Background
Preoperative plasma levels of Interleukin 6 (IL6) and its soluble receptor (IL6sR) have previously been associated with oncologic outcomes in urothelial carcinoma of the bladder (UCB); however, external validation in patients treated with radical cystectomy (RC) for UCB is missing.

Patients/methods
We prospectively collected preoperative plasma from 1,036 consecutive patients at two institutes. These plasma specimens were assessed for levels of IL6 and IL6sR. Logistic and Cox regression analyses were used to assess the correlation of plasma levels with pathologic and survival outcomes. The additional clinical net benefits of preoperative IL6 and IL6sR were evaluated using decision curve analysis (DCA).

Results
Median IL6 and IL6sR plasma levels were significantly higher in patients with adverse pathologic features. Elevated biomarker levels were independently associated with an increased risk for lymph node metastasis and ≥ pT3 disease. Both biomarkers were independently associated with recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS). The addition to, respectively, fitted pre- and postoperative prognostic models improved the predictive accuracy for lymph node metastasis, ≥ pT3 disease, RFS and CSS on DCA.

Interpretation
We confirmed that elevated preoperative plasma levels of IL6 and IL6sR levels are associated with worse oncological disease survival in patients treated with RC for UCB in a large multicenter study. Both biomarkers hold potential in identifying patients with adverse pathological features that may benefit from intensified/multimodal therapy and warrant inclusion into predictive/prognostic models. They demonstrated the ability to improve the discriminatory power of such models and thus guide clinical decision making.
