Published: June 2022

ABSTRACT
Primary colorectal lymphoma is a rare neoplasm. We report the case of a fistula between a diffuse large B-cell lymphoma of the sigmoid colon and an ovarian teratoma. An emergent laparotomy for an acute abdomen in a 90-year-old woman was performed. A pelvic mass of 12 × 9 cm fistulized in the left colon was found with the presence of gas and free liquid within the abdomen. This is an extremely rare condition, and as far as we know, no cases of a fistula between a large B-cell colonic lymphoma and an ovarian teratoma are present in the literature.
Sortledton

Despite the wide adoption of graph processing across many different application domains, there is no underlying data structure that can serve a variety of graph workloads (analytics, traversals, and pattern matching) on dynamic graphs with transactional updates.
In this paper, we present Sortledton, a universal graph data structure that addresses the open problem by being carefully optimizing for the most relevant data access patterns used by graph computation kernels. It can support millions of transactional updates per second, while providing competitive performance (1.22x on average) for the most common graph workloads to the best-known baseline for static graphs - CSR. With this, we improve the ingestion throughput over state-of-the-art dynamic graph data structures, while supporting a wider range of graph computations under transactional guarantees, with a much simpler design and significantly smaller memory footprint (2.1x that of CSR).

Published: June 2022

Distributed machine learning (ML) can bring more computational resources to bear than single-machine learning, thus enabling reductions in training time. Distributed learning partitions models and data over many machines, allowing model and dataset sizes beyond the available compute power and memory of a single machine. In practice though, distributed ML is challenging when distribution is mandatory, rather than chosen by the practitioner. In such scenarios, data could unavoidably be separated among workers due to limited memory capacity per worker or even because of data privacy issues. There, existing distributed methods will utterly fail due to dominant transfer costs across workers, or do not even apply.
We propose a new approach to distributed fully connected neural network learning, called independent subnet training (IST), to handle these cases. In IST, the original network is decomposed into a set of narrow subnetworks with the same depth. These subnetworks are then trained locally before parameters are exchanged to produce new subnets and the training cycle repeats. Such a naturally "model parallel" approach limits memory usage by storing only a portion of network parameters on each device. Additionally, no requirements exist for sharing data between workers (i.e., subnet training is local and independent) and communication volume and frequency are reduced by decomposing the original network into independent subnets. These properties of IST can cope with issues due to distributed data, slow interconnects, or limited device memory, making IST a suitable approach for cases of mandatory distribution. We show experimentally that IST results in training times that are much lower than common distributed learning approaches.
English Portions of the Marriage ordo in Manuscripts of German Provenance: An Edition of Two Middle English Texts in Hanover, Stadtbibliothek, Mag. 3, and Munich, Bayerische Staatsbibliothek, Clm 705
Authors: Schultze Dirk 
Published: June 2022

AbstractThe two manuscripts under discussion are testimonies of two processes, both understudied: first, the codification of English portions in the marriage liturgy in late-medieval England, and secondly, the exchange of manuscripts between England and continental Europe in the later Middle Ages up to and including the sixteenth century. The English fragments in Hanover, Stadtbibliothek, Mag. 3, were reused in Germany in the late fifteenth century, while the Sarum missal in Munich, Bayerische Staatsbibliothek, Clm 705, must have travelled to its current repository in the late sixteenth century. Through the English portions contained in them, they contribute in unique ways to a corpus of marriage-related English micro-texts that can be sourced mainly from liturgical manuscripts and early prints. In what follows, I shall offer a description of the two manuscripts and provide information about their provenance and the transmission to their current German repositories. The English portions and relevant extracts from the Latin are being edited here for the first time, and I will situate them within the corpus of extant English marriage ordines.
Motivation in a Reciprocal Task: Interaction Effects of Task Meaning, Goal Salience, and Time Pressure
Authors: Wagner Valentin , Riener Gerhard 
Published: June 2022

Abstract
We investigate the effectiveness of task meaning, time pressure, and knowing the upper bound of performance (maximum performance goal) in a reciprocal information digitization task and their interactions. Participants search information about schools where the quantity dimension of information refers to the number of schools and the quality dimension to finding the correct name of the headmaster. We obtain measures of quality (correctly entered information) and quantity (number of digitized entities). Time pressure has a positive effect on quantity and a negative on quality. Moreover, we cannot replicate the positive effects of high task meaning found in previous research. This indicates that its effectiveness might depend on the work context. While time pressure significantly decreases quality, its interaction with task meaning and maximum performance goals increases quantity marginally without loss in quality.
Obama’s Party? An Examination of Whether a Reluctant Party Leader Transformed the Democratic Party in his Favor
Authors: Azari Julia R. , Masket Seth 
Published: June 2022

Abstract
We examine Barack Obama’s influence over the Democratic Party as an ex-president from three vantage points: his popularity among partisans, his control over party nominations, and his rhetorical influence over party platform stances. The findings are somewhat mixed. Compared with other contemporary presidents, Obama is far more popular among co-partisan voters. However, he has had only modest influence in presidential nominations, and, unlike other modern presidents, a waning influence on party platform stances. The findings are suggestive not only about Obama’s own interests but also about institutional constraints of modern presidents.
Development of a CPU-GPU heterogeneous platform based on a nonlinear parallel algorithm
Authors: Ma Haifeng 
Published: June 2022

Abstract
In order to seek a refined model analysis software platform that can balance both the computational accuracy and computational efficiency, a CPU-GPU heterogeneous platform based on a nonlinear parallel algorithm is developed. The modular design method is adopted to complete the architecture construction of structural nonlinear analysis software, clarify the basic analysis steps of nonlinear finite element problems, so as to determine the structure of the software system, conduct module division, and clarify the function, interface, and call relationship of each module. The results show that when the number of model layers is 10, the GPU is 210.5/s and the CPU is 1073.2/s, and the computational time of the GPU is significantly better, with an acceleration ratio of 5.1. For all the models, the GPU calculation time is much less than that of the CPU, and when the number of model degrees of freedom increases, the acceleration effect of the GPU becomes more obvious. Therefore, the CPU-GPU heterogeneous platform can more accurately describe the nonlinear behavior in the complex stress states of the shear walls, and is computationally efficient.

Published: June 2022

Abstract
The main goal of this inspection is to explore the heat and mass transport phenomena of a three-dimensional magnetohydrodynamic (MHD) flow of ternary hybrid nanoliquid through a porous media toward a stretching surface. Nowadays, the low thermal conductivity is the key problem for scientist and researchers in the transmission of heat processes. Therefore, in order to improve the thermal conductivity of different base liquids, the scientist and researchers are mixing numerous types of solid particles in the base fluids. That is why the authors have mixed three different types of nanoparticles such as graphene oxide, silver, and copper in a kerosene oil base liquid. The influences of Hall current and ion-slip are also considered. Furthermore, the flow behavior is analyzed under the appliance of Darcy–Forchheimer, activation energy, and chemical reaction. By using the concept of boundary layer theory, the flow equations are modeled in the form of higher order nonlinear partial differential equations (PDEs) along with convective boundary conditions. Suitable similarity transformations are used for the transformation of higher order PDEs into the higher order nonlinear ordinary differential equations (ODEs). Analytical scheme known as the homotopic scheme is utilized for the simulation of the current problem. The impacts of discrete flow parameters on the velocities, temperature, and concentration profiles of the ternary hybrid nanoliquid are inspected. The skin friction coefficients, Nusselt number, and Sherwood number of the ternary hybrid nanofluid are investigated against various flow parameters. The outcomes of the current analysis showed that primary velocity of the ternary hybrid nanoliquid is augmented via Hall current and ion-slip number, while the reverse trend is observed via porosity parameter, Darcy–Forchheimer parameter, and magnetic field parameter. On the other hand, the higher values of Hall current and magnetic parameter enhanced the secondary velocity of the ternary hybrid nanoliquid, while the secondary velocity was reduced due to the increasing ion-slip number and rotation parameter. It is found that the heat transfer rate of the ternary hybrid nanofluid is 46% greater than the silver nanofluid.

A TANULMÁNY CÉLJA
A technikai fejlődés és a digitalizáció hatására új médiafogyasztási felületek jelentek meg, ezen az új piacon pedig a szórakoztatóipar egy eddig nem létező kínálatot alakított ki, ennek részeként jött létre az e-sport. Az elektronikus játékok és a hozzá tartozó tartalmak aktív és passzív fogyasztása is népszerű a fiatalok között. A kapcsolódó szolgáltatók és a gazdasági környezet felmérése elsődleges fontosságú, ha egy új, fejlődő iparágat szeretnénk vizsgálni, hogy meghatározhassuk azon tényezőket, amelyek befolyással vannak az e-sport iparra. Célunk bemutatni az e-sport tevékenységet gazdasági szempontból vizsgáló, jelenleg fellelhető, mind kvalitatív, mind kvantitatív tudományos kutatásokat, publikációkat.
ALKALMAZOTT MÓDSZERTAN
Az elérhető és releváns online adatbázis kereső rendszerekben célzottan, azonos keresőszavak (magyar és angol) révén szűkítettük a kutatás fókuszát az alábbiak szerint: (1) esport, e-sport, electronic sport és (2) economy, economics, business, revenue, income, sponsorship. Az adatbázis keresők egy részénél nem volt lehetőségünk szűkíteni a keresésünket a specifikus keresőszavak összekapcsolásával, ott törekedtünk a teljes feldolgozásra, a hógolyó-módszerrel választottunk ki minél több cikket, azok közül, amelyek megjelentek. A fellelhető irodalom áttekintése folyamán részletesen elemeztük azokat a publikációkat, amelyek címében vagy tartalmában megtalálhatóak voltak a fenti keresőszavak. Ezután kizártuk azokat a publikációkat, ahol ezen keresőszavak megléte ellenére tartalmilag mégsem volt releváns információ az e-sport iparággal kapcsolatban.
LEGFONTOSABB EREDMÉNYEK
Az e-sport iparág az élményalapú gazdaság részeként jellemezhető, egyfajta technológiai és szórakoztató iparági hibridként. Az e-sportot a szórakoztatóipar egy új, erősödő szereplőjeként határozhatjuk meg. A kutatás ideje alatt 33 olyan cikket találtunk, amely gazdasági értelemben foglalkozik az e-sport iparág valamely szegmensével. Feltárásra került a pénz körforgása az e-sport iparágban, ahol a követők/nézők számos terméket és szolgáltatást fogyasztanak: versenyek megtekintése, online és offline belépőjegyek vásárlása, egyéni és csapat támogatások, valamint „merchandising” termékek vásárlása. Cserébe élményeket, tárgyi eszközöket, szoftvereket, tapasztalatokat, valamint a videómegosztó felületeken, feliratkozások általi ajándékokat kaphatnak.
GYAKORLATI JAVASLATOK
A növekvő bevételek és a nézők számának növekedése miatt érdemes a további kutatások fókuszába helyezni az e-sport egyes szegmenseit, a közvetítésmegosztó szolgáltatókról csekély tudományos munka született eddig, amely a Magyarországon elérhető ilyen szolgáltatók nézőit vizsgálja, ezért ennek vizsgálatát elsődlegesnek gondoljuk.
A német szenior utazók tipológiája a Covid-19 járvány időszakában
Authors: Bíró Csaba , Gerdesics Viktória 
Published: June 2022

A TANULMÁNY CÉLJA
A szeniorturizmus már az 1970-es évektől létezik a köztudatban a német küldőpiac vonatkozásában, de az ezredfordulóig jellemzően niche-piacként tekintett rá a szakma. Az idős német utazók bővülő volumene ellenére, a számuk folyamatosan erodálódik a hazai desztinációkban. A fogyasztói magatartásuk, döntéshozataluk a turizmus szektoron belül kevésbé vizsgált és jellemzően sztereotipizált annak ellenére, egyre aktívabbak és tanultabbak a korábbi generációkhoz képest. Az idős utazók szegmense rendkívül heterogénnek tekinthető. Az empirikus vizsgálatunk legfőbb célja ezért az volt, hogy meghatározott szempontok mentén homogén csoportokat sikerüljön azonosítani a szegmensen belül, ezzel egy új tipológiát létrehozva az idős német utazók szegmensén belül.
ALKALMAZOTT MÓDSZERTAN
A 2019 évvégén kirobbant Covid-19 világjárvány komoly kihívások elé állította a turizmust. A lezárásokkal teli időszakokban többször is a nullához konvergált a szektor teljesítménye. Már a részleges újraindulás időszakában, 2021. július-október között személyes megkérdezésre (PAPI, in-situ, félig strukturált kérdőív segítségével) került sor, ahol a Magyarországra érkező, legalább 55 éves német beutazók kerültek kiválasztásra. A megkérdezés helyszíne Budapest, Kalocsa, Pécs volt. A végső mintát 347 fő idős német állampolgár alkotta, akik szállodahajó segítségével kerestek fel többek között hazai, Duna menti turisztikai térségeket. Megvizsgáltuk a desztinációválasztási döntéssel összefüggésben a desztináció preferenciájukat, illetve meghatározó utazási szokásaikat. A faktoranalízis alapját 49 db változó képezte, amelyek numerikusan (legalább számmal kódolható módon) értelmezhetőek. Az exploratív faktoranalízist főkomponens-elemzéssel, varimax forgatással végeztük el. Ezek alapján főkomponensek kerültek meghatározásra úgy, mint Covid-19 járvány és biztonság, Extra desztinációs elvárás, valamint az Árérzékenység és család. Klaszterezés segítségével jól elkülönülő csoportokat kerestünk. Ennek eredményeképpen 5 db klaszter került létrehozásra a vizsgált minta esetében, úgy, mint idős biztonságkeresők, igényes utazók, újgazdagok, örömutazók, valamint árérzékenyek csoportját azonosítottuk az időskorú német utazók szegmensén belül.
LEGFONTOSABB EREDMÉNYEK
Vizsgálati eredményeink kiválóan szemléltetik, hogy hibás gyakorlatnak minősül egy adott nemzet szenior utazói szegmensét egységesen, homogénnek kezelni, hiszen a szocio-gazdasági státus mellett, a desztinációs elvárások, a küldőterületi lokáció különbözősége mind-mind befolyással bírhatnak a turisztikai fogyasztás vonatkozásában.
Health-related quality of life following FDG-PET/CT for cytological indeterminate thyroid nodules

Published: June 2022

Objective
This study assessed the health-related quality of life (HRQoL) in patients undergoing 2-[18F]fluoro-2-deoxy-D-glucose (FDG)-PET/CT for an indeterminate (Bethesda III/IV) thyroid nodule. FDG-PET/CT accurately rules out malignancy and prevents 40% of futile diagnostic surgeries in these nodules.

Design
Secondary analyses of HRQoL data from a randomised controlled multicentre trial (NCT02208544) in 126 patients from 15 hospitals in the Netherlands were done.

Methods
Longitudinal HRQoL assessment was performed using the EuroQol 5-dimension 5-level (EQ-5D-5L), the RAND 36-item Health Survey v2.0 (RAND-36), and the Thyroid Patient-Reported Outcome (ThyPRO) questionnaire on baseline, 3, 6, and 12 months, relative to the date of the FDG-PET/CT scan.

Results
Patients who were randomised to active surveillance following an FDG-negative nodule instead of diagnostic surgery reported stable HRQoL scores throughout the year. Univariate analysis indicated better HRQoL for patients undergoing surveillance than surgical patients with benign histopathology on multiple physical and psychosocial domains. Univariate within-group analysis suggested both temporary and continued HRQoL deteriorations in patients with benign histopathology over time. Multivariate within-group analysis demonstrated no significant longitudinal HRQoL changes in patients undergoing active surveillance. In contrast, in patients with benign histopathology, worse HRQoL was observed with regard to ThyPRO cognitive impairment (P = 0.01) and cosmetic complaints (P = 0.02), whereas goitre symptoms (P < 0.001) and anxiety (P = 0.04) improved over time. In patients with malignant histopathology, anxiety also decreased (P = 0.05).

Conclusions
The reassurance of a negative FDG-PET/CT resulted in sustained HRQoL throughout the first year of active surveillance. Diagnostic surgery for a nodule with benign histopathology resulted in more cognitive impairment and physical problems including cosmetic complaints, but improved goitre symptoms and anxiety. Anxiety was also reduced in patients with malignant histopathology.

Published: June 2022

Summary
Pituitary apoplexy (PA) is a medical emergency with complex diagnosis and management. In this study, we describe a case of PA in a 63-year-old male treated with oral anticoagulant therapy for atrial fibrillation. In the patient, PA manifested itself with asthenia and severe headache not responsive to common analgesics. Despite the finding of a pituitary mass through CT, and in anticipation of the endocrinological evaluation and pituitary MRI, the patient’s clinical condition worsened with an escalation of headache and asthenia associated with deterioration of the visual field and impairment of consciousness level. The emergency assessments revealed an adrenal failure, whereas MRI showed a haemorrhagic pituitary macroadenoma with compression of the optic chiasm. Intravenous fluids repletion and high-dose hydrocortisone were started with a rapid improvement of the patient’s health and visual field abnormalities. Hydrocortisone was gradually reduced to a replacement dose. During the follow-up, panhypopituitarism was documented, and replacement therapies with l-thyroxine and testosterone were introduced. Three months later, a pituitary MRI showed a 50% reduction in the pituitary adenoma volume.

Learning points

Pituitary apoplexy (PA) is a medical emergency that can result in haemodynamic instability and abnormalities in the level of consciousness.

The management of PA requires a multidisciplinary team that includes endocrinologists, ophthalmologists, neuro-radiologists, and neuro-surgeons.

Pituitary MRI with gadolinium is the diagnostic gold standard for PA.

PA therapy aims to improve general conditions and treat compression symptoms, especially visual field abnormalities.

Adrenocorticotrophic hormone deficiency is a common and severe complication of PA. Thus, all patients with PA must be promptly treated with injective synthetic glucocorticoids (e.g. hydrocortisone 100 mg) and i.v. saline.

PA must be taken into consideration in case of sudden headache in patients with a pituitary macroadenoma, especially if other risk factors are recognized.
Comparative study of performances of UHPLC-MS/MS and HPLC/UV methods for analysis of ziprasidone and its main impurities

Published: June 2022

AbstractZiprasidone is the second generation antipsychotic drug with unique multipotent G-protein-coupled (GPCR) receptor binding profile. Since ziprasidone is a highly lipophilic and unstable compound, development of efficient method for a concurrent assay of ziprasidone and its main impurities was a very challenging task.The UHPLC-MS/MS method that we developed for simultaneous determination of ziprasidone and its main impurities (BITP, Chloroethyl-chloroindolinone, Zip-oxide, Zip-dimer, and Zip-BIT) was compared with some other related HPLC-UV methods of our own and other authorship. An increase of the mobile phase pH value from 2.5 to 4.7 units in the examined analytical methods influenced elution order of the investigated compounds. It was found out that the UHPLC-MS/MS method is more selective and sensitive than the earlier developed HPLC-UV method. Similar to our earlier HPLC-UV method, the UHPLC-MS/MS method is linear with a correlation coefficient (r) above 0.99 for all the analysed compounds, but with a negligibly lower precision and accuracy. Finally, with shorter analysis time, smaller column size and reduction of solvent consumption, UHPLC-MS/MS is assumed as a greener method than HPLC-UV for the ziprasidone purity assay.After transfer of the UHPLC-MS/MS method to the UHPLC-DAD system, suitability of the UHPLC-DAD method for routine control of ziprasidone and its main impurities is examined and confirmed based on the retained good selectivity, resolution and short analysis time.
