Influence of pedicle screw thread width and recovery time after surgery on fixation strength
Authors: Makaram Harikrishna , Swaminathan Ramakrishnan 
Published: December 2021

Abstract
Introduction: Pedicle screw fixation systems are widely used for treatment of various spinal pathologies, including spinal stenosis, scoliosis, spinal deformities and fractures. Stress shielding is considered to be a major factor contributing to insufficient fixation strength, leading to screw loosening. In this study, the influence of pedicle screw thread width on the displacement of pedicle screw and stress transfer is analyzed using 2-Dimensional axisymmetric finite element (FE) model. Methods: FE model consisting of cancellous and cortical bone, along with pedicle screw is developed for this study. The pedicle screw thread width is varied between 0.1 mm and 0.6 mm in steps of 0.1 mm, while the other geometric parameters, including screw half-angle, pitch, diameter, and length are kept constant. Three different contact conditions between screw and bone, such as frictionless, frictional, and bonded are considered to simulate hours, days, and months after surgery, respectively. The material properties and boundary conditions are applied based on previous studies. An axial force of 80 N is applied on the screw head to simulate axial pull-out test. Results: Similar patterns of stress distribution are observed for all screw models, with high stress concentration above the first thread. The highest displacement in screw is observed shortly after surgery, while the highest displacement in cancellous and cortical bone is observed few days and months after the surgery, respectively. The average von Mises stress in screw decreases with increase in thread width for all contact conditions. In few hours/days after the surgery, stress transfer parameter increases with increase in thread width, up to a thread width of 0.5 mm and then decreases. The changes in stress transfer parameter are negligible few months after the surgery.
Conclusion: This study highlights the influence of thread width on displacement and stress transferred to the bone, at different durations after the surgery. It is observed that a thread width of 0.5 mm exhibits the highest stress transfer, leading to reduced stress shielding and improved bone remodeling. It appears that this study might aid in developing better pedicle screws for the treatment of various spinal pathologies.

Published: December 2021

Abstract
Alzheimer’s Disease (AD) is an irreversible progressive neurodegenerative disorder. Magnetic Resonance (MR) imaging based deep learning models with visualization capabilities are essential for the precise diagnosis of AD. In this study, an attempt has been made to categorize AD and Healthy Controls (HC) using structural MR images and an Inception-Residual Network (ResNet) model. For this, T1- weighted MR brain images are acquired from a public database. These images are pre-processed and are applied to a two-layer Inception-ResNet-A model. Additionally, Gradient weighted Class Activation Mapping (Grad-CAM) is employed to visualize the significant regions in MR images identified by the model for AD classification. The network performance is validated using standard evaluation metrics. Results demonstrate that the proposed Inception-ResNet model differentiates AD from HC using MR brain images. The model achieves an average recall and precision of 69%. The Grad- CAM visualization identified lateral ventricles in the mid-axial slice as the most discriminative brain regions for AD classification. Thus, the computer aided diagnosis study could be useful in the visualization and automated analysis of AD diagnosis with minimal medical expertise.
Tracking blood pressure changes by means of non-invasive intermittent blood pressure measurements in clinical application
Authors: Huhle Robert , Richter Thorsten , Gama de Abreu Marcelo 
Published: December 2021

Abstract
Considering accuracy/precision cut-offs of 5 ± 8 mmHg and cut-off values for inter-class correlation coefficients (ICC=0.37...1, from DIN EN ISO 81060-2), absolute and relative errors in time independent measurement of blood pressure changes with non-invasive intermittent devices (NiBP) are derived mathematically for mean arterial blood pressure range of 40-180 mmHg. As a clinically relevant value for change of arterial blood pressure 20% of the baseline blood pressure is considered. The mean ratio between the change of BP measured by the NiBP and measured by the invasive reference device (TE%) were proposed as quality measure for the evaluation of NiBP device tracking capability. The proposed measure TE%is theoretically independent of absolute accuracy but depends on precision and ICC of a device. NiBP devices show considerable maximum TE% of 41% in tracking mean blood pressure changes respectively. In 10% of the measurements in the low blood pressure range TE% exceeding 100%. The mean 50th/90th TE% percentile over the whole blood pressure range were 25/61%, respectively. Furthermore, TE% was relatively insensitive to assumed blood
pressure range but sensitive to ICC. NiBP devices have high relative error in tracking blood
pressure changes that make those devices not well-suited for tracking blood pressure changes. The proposed tracking error allows the definition of reasonable accuracy/precision requirements of NBP devices.
Hemodynamics of anterior communicating artery aneurysms using combined imaging of the anterior circulation
Authors: Saalfeld Sylvia , Behme Daniel , Almizel Mahmoud , Berg Philipp 
Published: December 2021

Abstract
Intracranial aneurysms at the anterior communicating artery (AcomA) are associated with a higher rupture risk and a more challenging therapy since they are supplied with blood from both sides of the anterior vasculature. Since the standard imaging modality, i.e. digital subtraction angiography, involves the contrast agent injection into a single cerebral artery, this relationship cannot be satisfactorily considered in subsequent blood flow analysis based on the single-sided segmentation. In this study, we analysed five patients harbouring multiple intracranial aneurysms including those located at the AcomA. We virtually combined the segmentations from both sides into a single model and examined the influence on blood flow simulations based on different inlets: (1) only the left internal carotid artery, (2) only the right internal carotid artery and (3) both internal carotid arteries. Our results indicate a strong influence of the blood flow simulation for AcomA aneurysms as well as large differences between left and right side of the patient’s vasculature

Published: December 2021

Abstract
Intracranial aneurysms (IA) is not-uncommon pathology of cerebral vessels. Vessel wall magnetic resonance imaging can visualize the vascular walls of IAs. In some aneurysms, the wall-adjacent and a luminal hyperintense signal was detected. The signal was attributed to the inflammation and specific hemodynamic features of aneurysms. But, up to now, the studies investigating luminal enhancement combined with flow analysis are limited. Therefore, in this study, investigation of the luminal enhancement is further carried out by comparison to computational fluid dynamics. The latter provides the possibility of calculating hemodynamic parameters, which can give information such as velocity, pressure, and shear stress fields throughout a heart cycle. The data of the IAs is specific to each patient and builds the basis for the enhancement analysis and simulations. Specific hemodynamic parameters like kinetic energy and vortex formation evaluated in the simulations show a dependency to signal suppression recorded with vessel wall magnetic resonance imaging

Abstract
This contribution describes how to improve privacy and security for the Smart Living domain. Core elements of this approach adapt the Privacy by Design concept to the domain of smart living and extend it to enable artificial intelligence integration. To improve security, we created a minimum framework based on an existing information security management system to offer a holistic perspective on that topic. This, we think, is necessary, primarily if legacy Internet of Things devices should be supported
Visualizing the Knowledge Domain of Motor Speech Disorders: A Scientific Review (2000-2019)
Authors: Wang Huili , Zhang Shurong , Li Xueyan 
Published: December 2021

Abstract
This review visualizes the knowledge domain of motor speech disorders (MSDs) in linguistics between 2000 and 2019 by means of scientometric methods. With topic searches, the study collected 869 bibliographic records and 20, 411 references from Web of Science Core Collection (WoSCC) of Thomson Reuter. The clustered and visualized document co-citation network of the MSDs knowledge domain in CiteSpace identifies 15 research foci in different periods, including apraxia of speech, acoustics, children, technology, aphemia, childhood apraxia of speech, primary progressive aphasia, speech motor delay, Parkinson’s disease, amyotrophic lateral sclerosis, rhythm, foreign accent syndrome, phonation, phonological awareness, dose and speech perception. Revolving around linguistics, these foci could be divided into studies on speech characteristics of MSDs in terms of phonology and phonetics, remedies for MSDs in terms of neurolinguistics and acoustic phonetics, dysarthria secondary to neurological diseases based on pathological linguistics, subtypes of apraxia of speech, methods of MSDs based on auditory phonetics and a newly recognized subtype of MSDs. Meanwhile, the emerging trends of MSDs in linguistics are detected by the analysis of reference citation bursts, suggesting growing research in remedies for MSDs with the focus on assessments and effectiveness of treatments, speech characteristics and indexes of dysarthria secondary to neurological diseases and assistance to diagnose apraxia of speech. To sum up, the review has indicated that the acoustic measures to assess MSDs and acoustic remedies for dysarthria may not only be the past foci but also be future trends.
The Connections Between Founders’ Social Network and Human Capital in Technology-Based New Ventures
Authors: Zane Lee J. , DeCarolis Donna Marie 
Published: December 2021

Abstract
This research examines the relationship between a founding team’s social network and the acquisition of its critical human capital. First, explicitly dealing with technology-based firms, we disaggregate the founder(s) social network into four sub-networks: academic, industry, finance, and personal (family and community). Then, we detail the relationship between these individual sub-networks and the acquisition of both technical and business skilled human capital. Our results confirm that individual sub-networks have a differential effect on acquiring both technical and business human capital.
Methodology for the identification of economic, environmental and health criteria for road noise mitigation
Authors: D’Alessandro Francesco , Di Mascio Paola , Lombardi Lorenzo , Ridolfi Benedetta 
Published: December 2021

Abstract
The aim of the paper is to define a method for evaluating infrastructural interventions for the mitigation of noise generated by roads based on multi-criteria analysis which considers a series of parameters (environmental, social, economic and health) that could give broader evaluations than just economic convenience.
The research develops a guideline based on an already known methodology applied in other fields, which has been adapted to the above-mentioned topic: the multi-criteria analysis. The decision to use this method originates from an in-depth study of the state of the art regarding the issue of noise pollution related to transport infrastructures in Italy and at a European level.
The Multi-criteria Analysis proved to be the best solution both for completeness and versatility. In particular, the developed methodology uses the Analytic Hierarchy Process as a multi-criteria analysis method. Through its hierarchical structure, this method offers a comparison not only between possible interventions, but also between the same criteria taken into consideration for the choice of the best intervention. The model was validated by analyzing a real noise mitigation project on an Italian main road. The results showed how the model could represent a valid support to decision-making processes.
Some notes on central causal clauses in Venetian
Authors: Catasso Nicholas 
Published: December 2021

AbstractThe goal of this paper is to provide novel evidence in favor of an integration of Haegeman’s (2002) taxonomy of adverbial clause subordination by discussing some data from C-introduced causal constructs in Venetian, the Italo-Romance dialect spoken in the city of Venice. Haegeman’s model is based on a two-class categorization of adverbial structures into central clauses, in which matrix-clause phenomena (such as the licensing of some sentence-initial or sentence-final discourse particle-like items, XP-fronting) are excluded, and peripheral clauses, in which these phenomena are licit. The external-syntactic distinction predicted by this model, namely a semantic differentiation resulting from TP/VP-adjunction for central vs. CP-adjunction for peripheral adverbial clauses, has severe consequences for the internal syntax of the a/m constructions, the most striking being the absence of the upper projections of the Split CP of central constructs. The data presented in this paper, however, suggest that (at least) in Venetian, (some) main-clause phenomena may also be licensed in central adverbial clauses under specific circumstances. Additionally, it will be shown that the conclusions drawn from the observation of the Venetian data match the behavior of the same constructions in Standard Italian, as well as in other languages, under the very same conditions.

Published: December 2021

Abstract
In this paper we introduce different families of numerical and polynomial sequences by using Riordan pseudo involutions and Sheffer polynomial sequences. Many examples are given including dual of Hermite numbers and polynomials, dual of Bell numbers and polynomials, among other. The coefficients of some of these polynomials are related to the counting of different families of set partitions and permutations. We also studied the dual of Catalan numbers and dual of Fuss-Catalan numbers, giving several combinatorial identities.
Nabû, the Avenger
Authors: Schwemer Daniel 
Published: December 2021

Abstract
B 158 is a Seleucid-period manuscript of the bilingual Balaĝ prayer Ukkin-ta eš-bar til-la. The tablet, which was found at Babylon in 1902 and is edited here for the first time, contains major portions of text that have hitherto been unknown. The prayer is suffused with first-millennium Nabû theology and contains a unique literary request for revenge against the enemy in the mountain lands. The findspot of B 158 may shed light on the provenance of the Late Babylonian kalûtu library of the Nanna-utu family.
Der Flussname Inn, Ockhams Rasiermesser und moderne Indogermanistik
Authors: Bichlmeier Harald 
Published: December 2021

Abstract
Some European hydronyms (among them also the river-name Inn) have sometimes been explained based on a root PIE “ *en‑/*on‑” (modern spelling: PIE *h₁en(H)-), which has usually been given the meaning ‘flow, river’ vel sim. This root cannot even be found in Pokorny’s Indogermanisches etymologisches Wörterbuch (1959). No real proof for that root has been found in the appellative lexicon of any Indo-European language. Moreover, there aren’t any sure continuations of that root in the onymic lexicons of those languages. All names put forward as arguments can either be explained based on a root PIE *pen-/*pon- ‘swamp, (standing) water’ (because they are Celtic) or based on a root PIE *h₂en- ‘haul (water)’. As long as no proof of an appellative use of a root PIE *h₁en(H)- can be offered, which alone might tell us, what that root actually meant, the application of ‘Occam’s razor’ leaves us no other choice but to explain all regarding names from the other two roots.
Metabolically healthy obesity was significantly associated with increased risk of gallstones

Published: December 2021

Objective
The risk of gallstones among metabolically healthy obesity (MHO) individuals is largely unexplored. Therefore, the present study investigated the association between MHO and gallstones in a health check-up cohort of Chinese adults.

Design
A prospective cohort study.

Methods
Participants included 58 862 individuals from the MJ health check-up cohort aged ≥ 18 years without a history of gallstones at baseline. Gallstones were diagnosed using abdominal B-type ultrasound. Metabolically healthy was defined as not having any one of the components of metabolic syndrome. Obesity was identified by BMI and waist circumference (WC). Participants were cross-classified at baseline by metabolic health and obesity. Adjusted hazard ratios (HRs) and 95% CIs of gallstones across BMI or WC categories were estimated with Cox proportional hazard regression models.

Results
During a median follow-up of 3.0 years (interquartile range, 1.6–6.1), 1269 participants developed gallstones. Individuals with MHO (HR: 1.95, 95% CI: 1.23, 3.09 for BMI criteria; HR: 1.74, 95% CI: 1.37, 2.21 for WC criteria) had a significantly higher risk of gallstones than those with metabolically healthy normal weight. In metabolically healthy individuals, BMI and WC both displayed linear dose–response relationships with gallstones (P for non-linearity >0.05). The association between MHO and gallstones remained unchanged when using different criteria for metabolic health and obesity.

Conclusions
MHO was significantly associated with gallstones, suggesting that obesity can independently contribute to gallstones development, even among metabolically healthy individuals. These findings emphasize that metabolically healthy individuals may still benefit from maintaining normal body weight to prevent gallstones.

LITERARY AND THEOLOGICAL BACKGROUND OF THE SERMON ON LAW AND GRACE
Authors: МАЛМЕНВАЛЛ Симон 
Published: December 2021

This article studies the literary and theological background of the Sermon on Law and Grace, a famous oration by Ilarion, the (future) Metropolitan of Kyiv, from the mid-eleventh century. The author of this article focuses also on potential patristic models for Ilarion’s theological and patriotic reflection on the recent East Slavic history in the light of the official adoption of Christianity under Volodymyr Sviatoslavich, Prince of Kyiv. The main feature of the mentioned (self-)reflection, relying on the notion of history as the history of salvation, is disregarding the Byzantine political and cultural superiority and, simultaneously, emphasizing the justice of God, who brings his grace equally to all peoples, thus positioning them on the same spiritual level. This kind of reasoning was not a peculiarity of the Rus’ culture but formed a wider phenomenon defined by apologetic attitu­de and was characteristic of the entire religious-literary tradition of the East Orthodox Slavs between the tenth and sixteenth centuries. While trying to construct a theological justification of the historical value of Kyivan Rus’, Ilarion adapted patristic patterns coming from Byzantium, for example, the explanation of (dis)continuity between the Law of Moses and Christ’s mercy, particularly following Gregory Nazianzen and Patriarch Nicephorus I, or perception of a polity led by a Christian ruler, particularly following Eusebius of Caesarea.

УЯВЛЕННЯ МИХАЙЛА МАКСИМОВИЧА ПРО АВСТРІЙСЬКУ ГАЛИЧИНУ ТА ЙОГО ВЗАЄМИНИ З КРАЯНАМИ
Authors: Райківський Ігор 
Published: December 2021

У статті висвітлюється вплив М. Максимовича на національний рух в австрійській Галичині 30–70-х рр. ХІХ ст. В уявленні видатного українського дослідника-народознавця Галичина була не­від’ємною частиною русько-українського простору. Він зробив вагомий внесок в обґрунтування само­бутності та єдності української (“руської”, “малоруської”) мови і фольклорної спадщини обабіч авст­ро-російського кордону, спільності історичного минулого Галичини з підросійською Україною. М. Мак­си­мовичу так і не довелося особисто побувати в Галичині, але він підтримував багатолітні листовні сто­сунки з діячами “Руської трійці” І. Вагилевичем та Я. Головацьким, істориком Д. Зубрицьким. Ко­респон­денція мала інформаційно-науковий характер, охоплювала питання обміну книжками, відомостями про наукове й літературне життя. Галицькі народовці з 1860-х рр. використовували творчий доробок М. Макси­мовича у своїй видавничій діяльності для обґрунтування національної самобутності українського народу.
