Paraneoplastic factor XIII deficiency in a pregnant female with colon cancer: a case report
Authors: Schumacher Claire , Bauer Carole , Wilde Sigrid de , Paulus Patrick
Published: February 2021

Background:

Factor XIII deficiency, which can be congenital or acquired, is a rare disorder. It can cause life-threatening bleeding. It cannot be diagnosed by usual hemostasis tests; only by specific screening tests.

Case Presentation:

We report the case of a young pregnant woman whom we discovered a paraneoplastic factor XIII deficiency with the underlying cause of colorectal cancer.

Conclusion:

A paraneoplastic context concerning hematologic malignancies as well as solid tumors must not be ignored. No other case of paraneoplastic factor XIII deficiency resulting from colorectal cancer is previously reported in the literature.
Rare subtype of hepatoblastoma in a young adult: difficulties in the histopathological differentiation from hepatocellular carcinoma
Authors: Stamou Chrysa , Mitropoulou Georgia , Pavlou Kalliopi , Trihia Helen , Provatas Ioannis
Published: February 2021

Background:

Hepatoblastoma is a primary malignant tumor of the liver usually occurring in children, whereas it is very rare in adults, affecting males slightly more.

Case Presentation:

We report a case of a 20-year old female patient with a palpable liver mass and significantly elevated alpha-fetoprotein (AFP), Serum Glutamic Oxaloacetic Transaminase, and Serum Glutamic-Pyruvic Transaminase values. The microscopic examination revealed a mixed cell population of small cells with an oval-shaped nucleus and scant relatively basophilic cytoplasm co-existing with larger cells with eosinophilic or clear cytoplasm, round nuclei, arranged in trabeculae of six or more cells separated by thin fibrous septa. The immunohistochemical assessment of the tumor cells revealed positivity for AFP, Glypican-3, Glutamate Synthetase, polyclonal Carcinoembryonic antigen, Cytokeratin (CK8/18), and Epithelial Specific Antigen/Ep-CAM, membranous and focally nuclear positivity for b-catenin, focal positivity for CK19 and vimentin and faintly focal positivity for Sal-like protein-4 and Cluster Differentiation 99. The cell proliferation rate Ki-67 was high, at about 85% and concerning the prognostic markers, there was a positive expression of Cyclin D1 at approximately 80% of the tumor cells, whereas c-myc was negative. These findings drove us to the diagnosis of hepatoblastoma, macrotrabecular subtype.

Conclusion:

Although the age, medical history, clinical findings, and the laboratory investigations of the patient suggested hepatocellular carcinoma, on the histological examination the mixed blastematous morphology of the tumor combined with the results of the immunohistochemical assay, lead to the diagnosis of hepatoblastoma.
“It Shaped Who I Am”: Reframing Identities for Justice Through Student Activism
Authors: Gutierrez Keeton Rebecca , Benavides López Corina , Aguilar-Hernández José M.
Published: February 2021

On May 6, 1993, students of California State Polytechnic University, Pomona (Cal Poly Pomona [CPP]) protested what they believed was a lack of diversity on campus. Over 25 years later, this qualitative study explores the identity development of undergraduate students who led that movement, which resulted in the founding of five cultural centers at CPP in 1995. In doing so, this study adds to the growing literature on activism and Chicana/o/x and Latina/o/x identity development. Today, student-led movements shine light on continued inequities in higher education. The reframing identities for justice (RIJ) identity development model serves as a lens to explore how six students’ historical narratives offer a unique glimpse into the impact of activism on their identity development. We found participants’ identity development was influenced by (a) experiencing meaningful interactions along their developmental journeys, (b) making sense of oppression and privilege, (c) discovering praxis between previous learning and activism at CPP, and (d) building coalitions and kinship. Findings show that students act for social justice before they explore multiple identities. We conclude that activism impacts student identity development and offer recommendations for how to enhance this development to student activists, faculty, and administrators.

Published: February 2021

The fast development of new technologies has a significant impact on the financial sector development. Digitalization leads to the development of new business models, transformation of value chains, new product delivery channels, relationships between companies in the financial sector and structural landscape of the financial sector changes to the. Although, there is no common understanding formed among scholars about the drivers of these strategic changes and the future financial sector development trends.The development of financial technologies, characterized by the emergence of alternative services and new industries, can be described as highly innovative. The functional equivalent of the commonly used terms, such as digital disruption and digital transformation is digital innovation, in one case emphasizing strategic orientation, developing new products and business models using digital technologies, infrastructures, supply chain, and ecosystems, and, in the other - transforming traditional models to address to existing loyal customers providing more usable in the digital ecosystems access channels, solutions, and products.
On Globalization and Business Competitiveness: A Panel Data Country Classification
Authors: Hameed Kamran , Arshed Dr Noman , Yazdani Dr Naveed , Munir Mubasher
Published: February 2021

Industrial competitiveness could be achieved through policies reforms favoring globalization process. The reality, however, is two-folded. Initially, government policies restrict globalization and impose barriers to trade, restrict social and political activities. Structural reforms become inevitable to remain in the competition. Local resources, human capital, infrastructure, education and health facilities should be transformed. It is done through deploying a flexible structure that is adapting social, political and economic changes coming from the globalization process in order to make the local industry competitive. This paper argues that beneficiaries of globalization earn this status through strategizing and processing their resources into a competitive position. This gap is covered by empirically investigating the U-shaped relationship between globalization and competitiveness. Furthermore, categorizing the selected countries into under or over globalized nations.
Frame-based versus frameless stereotactic brain biopsies: A systematic review and meta-analysis
Authors: Kesserwan Mohamad Ali , Shakil Husain , Lannon Melissa , McGinn Ryan , Banfield Laura , Nath Siddharth , Alotaibi Mazen , Kasper Ekkehard , Sharma Sunjay
Published: February 2021

Background:

Stereotactic brain biopsy techniques have been a focus of rapid technological innovation. The recent advent of frameless stereotaxy has invited the question of whether it can provide the same diagnostic yield as frame-based techniques, without increasing risk of harm to patients. The goal of this meta-analysis was to compare each of these techniques in terms of yield and safety.

Methods:

We independently searched four databases for English studies comparing frameless and frame-based stereotactic brain biopsies. Our primary outcome was biopsy diagnostic yield. Our secondary outcomes included mortality, morbidity (e.g., symptomatic postbiopsy intracranial hemorrhage, asymptomatic postbiopsy intracranial hemorrhage, new postbiopsy neurological deficit, and postbiopsy seizure), and frequency of repeat biopsy. We calculated pooled estimates and relative risks for dichotomous outcomes using Review Manager 5.3, with corresponding 95% confidence intervals.

Results:

A total of 3256 stereotactic brain biopsies (2050 frame based and 1206 frameless), from 20 studies, were included in our final analysis. The results did not demonstrate any significant difference between the two stereotactic systems in terms of diagnostic yield (risk ratio [RR] 1.00, 95% confidence interval [CI] 0.99–1.02, P = 0.64, I2 = 0%). The only significant difference was the increased frequency of asymptomatic hemorrhages in the frameless group (RR 1.37, 95% CI 1.06–1.75, P = 0.01, I2 = 0%). Application of Grading of Recommendations Assessment, Development, and Evaluation to the results yielded very low quality of all outcomes.

Conclusion:

Based on very low-quality evidence, both frame-based and frameless stereotaxy are safe and effective for biopsy of intracranial tumors. Further study of patient preference and cost comparing analysis is required to identify if either modality should be preferred.
Quantum algorithm for matrix functions by Cauchy's integral formula
Authors: Takahira Souichi , Ohashi Asuka , Sogabe Tomohiro , Usuda Tsuyoshi S.
Published: February 2021

For matrix A, vector b and function f, the computation of vector f(A)b arises in many scientific computing applications. We consider the problem of obtaining quantum state |f> corresponding to vector f(A)b. There is a quantum algorithm to compute state |f> using eigenvalue estimation that uses phase estimation and Hamiltonian simulation e^{\im A t}. However, the algorithm based on eigenvalue estimation needs \poly(1/\epsilon) runtime, where \epsilon is the desired accuracy of the output state. Moreover, if matrix A is not Hermitian, \e^{\im A t} is not unitary and we cannot run eigenvalue estimation. In this paper, we propose a quantum algorithm that uses Cauchy's integral formula and the trapezoidal rule as an approach that avoids eigenvalue estimation. We show that the runtime of the algorithm is \poly(\log(1/\epsilon)) and the algorithm outputs state |f> even if A is not Hermitian.
Quantum entanglement, supersymmetry, and the generalized Yang-Baxter equation
Authors: Padmanabhan Pramod , Sugino Fumihiko , Trancanelli Diego
Published: February 2021

Entangled states, such as the Bell and GHZ states, are generated from separable states using matrices known to satisfy the Yang-Baxter equation and its generalization. This remarkable fact hints at the possibility of using braiding operators as quantum entanglers, and is part of a larger speculated connection between topological and quantum entanglement. We push the analysis of this connection forward, by showing that supersymmetry algebras can be used to construct large families of solutions of the spectral parameter-dependent generalized Yang-Baxter equation. We present a number of explicit examples and outline a general algorithm for arbitrary numbers of qubits. The operators we obtain produce, in turn, all the entangled states in a multi-qubit system classified by the Stochastic Local Operations and Classical Communication protocol introduced in quantum information theory.
Quantum memory and quantum correlations of Majorana qubits used for magnetometry
Authors: Rangani H. , Haseli S.
Published: February 2021

We address how the non-local nature of the topological qubits, realized by Majorana modes and driven by an external magnetic field, can be used to control the non-Markovian dynamics of the system. It is also demonstrated that the non-local characteristic plays a key role in control and protection of quantum correlations between Majorana qubits. Moreover, we discuss how those non-local qubits help us to enhance quantum magnetometry.
On the depth overhead incurred when running quantum algorithms on near-term quantum computers with limited qubit connectivity
Authors: Herbert Steven
Published: February 2021

This paper addresses the problem of finding the depth overhead that will be incurred when running quantum circuits on near-term quantum computers. Specifically, it is envisaged that near-term quantum computers will have low qubit connectivity: each qubit will only be able to interact with a subset of the other qubits, a reality typically represented by a qubit interaction graph in which a vertex represents a qubit and an edge represents a possible direct 2-qubit interaction (gate). Thus the depth overhead is unavoidably incurred by introducing swap gates into the quantum circuit to enable general qubit interactions. This paper proves that there exist quantum circuits where a depth overhead in Omega(\log n) must necessarily be incurred when running quantum circuits with n qubits on quantum computers whose qubit interaction graph has finite degree, but that such a logarithmic depth overhead is achievable. The latter is shown by the construction of a 4-regular qubit interaction graph and associated compilation algorithm that can execute any quantum circuit with only a logarithmic depth overhead.

Published: February 2021

Here, we report a novel class of potent PD-L1/PD-1 inhibitors based on the rigidified biphenyl-inspired structure – terphenyls. Using in-silico docking, we designed and later experimentally shown the efficacy of terphenyl-based scaffolds to inhibit the PD-1/PD-L1 complex formation using various biophysical and biochemical techniques. We also report a high-resolution structure of the PD-L1 complex with our most potent inhibitors allowing the identification of key interactions with PD-L1 at the molecular level. Moreover, we show the efficacy of our most potent inhibitors at activating the antitumor response using primary T-cells derived from healthy donors. This effect was not observed even for the therapeutic antibodies. This makes our compounds prominent candidates for further optimization for anti-PD-L1 cancer treatments.
Enzymatic RNA Production from NTPs Synthesized from Nucleosides and Trimetaphosphate
Authors: Chizzolini Fabio , Kent Alexandra , Passalacqua Luiz F. M. , Lupták Andrej
Published: February 2021

A mechanism of nucleoside triphosphorylation would have been critical in an evolving “RNA world” to provide high-energy substrates for reactions such as RNA polymerization. However, synthetic approaches to produce ribonucleoside triphosphoates (rNTPs) have suffered from conditions such as high temperatures or high pH that lead to increased RNA degradation, as well as substrate production that cannot sustain replication. We demonstrate that cyclic trimetaphosphate (cTmp) can react with nucleosides to form rNTPs under mild, prebiotically-relevant conditions, with second-order rate constants ranging from 1.7 to 6.5 µM–1 s–1. The ATP reaction shows a linear dependence on pH and Mg2+, and an enthalpy of activation of 88 ± 4 kJ/mol. At millimolar nucleoside and cTmp concentrations, the rNTP production rate is sufficient to facilitate RNA synthesis by both T7 RNA polymerase and a polymerase ribozyme. We suggest that the optimized reaction of cTmp with nucleosides may provide a viable connection between prebiotic nucleotide synthesis and RNA replication.
Facilitators and Inhibitors of Mental Discrimination in the Workplace: A Traditional Review
Authors: Mellifont Damian
Published: February 2021

Discrimination can closely follow disclosure of neurodivergence in the workplace. This traditional review of the literature therefore aims to (a) critically explore factors that facilitate and inhibit mental discrimination in workplace environments, and (b) produce an evidence-based, anti-discrimination guide supporting neurodivergent employees. Applying content analysis to 64 scholarly articles retrieved from Scopus, ProQuest Central and PsycINFO (via OvidSP) databases, this traditional review offers three main messages which should be of value to HR policymakers and practitioners. First, the spirit of diversity and inclusion needs to be practically applied in recruitment processes so that neurodivergent applicants are not exposed to discrimination. Second, employees or prospective employees should not feel that they will be punished for disclosing their neurodivergence. Finally, sanist workplaces that refuse to be inclusive and accommodating of neurodivergent persons might experience lost productivity as a result.

Statistical analysis of small and medium-sized businesses in Russia for the period 2017-2019
Authors: Shumilina Vera , Kleptsov Vadim
Published: February 2021

The purpose of this article is to examine the concept of business and the role of enterprises in the economic development of society. This topic is relevant for Russia today. Business in the Russian Federation is of great importance in the development of the economy and the country as a whole. Only through the development and improvement of entrepreneurship does economic growth take place, scientific and technological progress is accelerated. Also, the business area has a huge impact on other areas of activity, such as: social, political and others. Another argument for the relevance of this work is that in Russia entrepreneurship, especially small business, does not receive proper development and only partially performs the functions inherent in it in developed market systems, because as you know, it is small business that is the engine of economic growth.

Thoughts on neurophysiological signal analysis and classification
Authors: Li Junhua
Published: February 2021

Neurophysiological signals are crucial intermediaries, through which brain activity can be quantitatively measured and brain mechanisms are able to be revealed. In particular, non‐invasive neurophysiological signals, such as electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI), are welcomed and frequently utilised in various studies since these signals can be non‐invasively recorded without harming the human brain while they convey abundant information pertaining to brain activity. The recorded neurophysiological signals are analysed to mine meaningful information for the understanding of brain mechanisms or are classified to distinguish different patterns (e.g., different cognitive states, brain diseases versus healthy controls). To date, remarkable progress has been made in both the analysis and classification of neurophysiological signals, but scholars are not feeling complacent. Consistent effort ought to be paid to advance the research of analysis and classification based on neurophysiological signals. In this paper, I express my thoughts regarding promising future directions in neurophysiological signal analysis and classification based on current developments and accomplishments. I will elucidate the thoughts after brief summaries of relevant backgrounds, accomplishments, and tendencies. According to my personal selection and preference, I mainly focus on brain connectivity, multidimensional array (tensor), multi‐modality, multiple task classification, deep learning, big data, and naturalistic experiment. Hopefully, my thoughts could give a little help to inspire new ideas and contribute to the research of the analysis and classification of neurophysiological signals in some way.

Low-frequency earthquakes reveal punctuated slow slip on the deep extent of the Alpine Fault, New Zealand
Authors: Chamberlain Calum , Shelly D , Townend John , Stern Timothy
Published: February 2021

We present the first evidence of low-frequency earthquakes (LFEs) associated with the deep extension of the transpressional Alpine Fault beneath the central Southern Alps of New Zealand. Our database comprises a temporally continuous 36 month-long catalog of 8760 LFEs within 14 families. To generate this catalog, we first identify 14 primary template LFEs within known periods of seismic tremor and use these templates to detect similar events in an iterative stacking and cross-correlation routine. The hypocentres of 12 of the 14 LFE families lie within 10 km of the inferred location of the Alpine Fault at depths of approximately 20-30 km, in a zone of high P-wave attenuation, low P-wave speeds, and high seismic reflectivity. The LFE catalog consists of persistent, discrete events punctuated by swarm-like bursts of activity associated with previously and newly identified tremor periods. The magnitudes of the LFEs range between ML - 0.8 and ML 1.8, with an average of M L 0.5. We find that the frequency-magnitude distribution of the LFE catalog both as a whole and within individual families is not consistent with a power law, but that individual families' frequency-amplitude distributions approximate an exponential relationship, suggestive of a characteristic length-scale of failure. We interpret this LFE activity to represent quasi-continuous slip on the deep extent of the Alpine Fault, with LFEs highlighting asperities within an otherwise steadily creeping region of the fault. © 2014.

The capital market is one of the economic drivers and representations for assessing the condition of companies in a country. Indonesia Stock Exchange (IDX) as one of the institutions in the capital market has 24 types of indexes that can be used as main indicators that reflect the performance of capital market, two of them are the Composite Stock Price Index (CSPI) and the Jakarta Islamic Index (JII). CSPI and JII movements are influenced by several factors, both from domestic and from foreign, such as inflation and the Dow Jones Industrial Average (DJIA). Modeling of CSPI and JII in this study was carried out using biresponses spline truncated nonparametric regression methods using Graphical User Interface (GUI) R with the intention of facilitating the analysis process. This method is used because there is a correlation between CSPI and JII and there is no specific relationship pattern between the response variable (CSPI and JII) and the predictor variable (inflation and DJIA). The best biresponses spline truncated model is determined by the order, number and location of the knots seen based on minimum GCV criteria. By using monthly data from January 2016 to December 2019, the best biresponses spline truncated model is obtained when the model for CSPI is in order 2 and the model for JII is in order 3 with 2 knots for each predictor variable. This model has a coefficient of determination of 85,54437% and MAPE of 2,65595% so that it has a very good ability in forecasting.
Milano Città d’Acqua, un debate actual en torno a la recuperación del patrimonio hidráulico

Pese a asentarse sobre un estrato hídrico que abastece de forma natural a sus habitantes y cultivos, Milán ha dedicado incansables esfuerzos a establecer una red de infraestructuras hidráulicas como conexión con otras ciudades. Un trabajo continuo de planificación ingenieril le permitió construir, a lo largo de su historia, un extenso sistema de canales navegables que salvase la distancia que la aleja de los ríos más próximos. Un gran empeño técnico por el que fue denominada por muchos la Città dell’acqua. Paradójicamente, la idea de prescindir de estas aguas antropogénicas surgió a raíz de uno de sus primeros planes urbanísticos, a finales del siglo XIX. Este artículo caracteriza la ciudad a través de un recorrido cronológico, centrándose en la hidrografía de la región y en sus principales obras hidráulicas medievales y modernas, los llamados navigli. A continuación, se exponen las circunstancias y argumentos urbanos que, tras la industrialización, llevaron a políticos, urbanistas e ingenieros a soterrar estas infraestructuras; coincidiendo con el desarrollo de las tecnologías sanitarias modernas y el auge del tráfico rodado frente a la navegabilidad. Por último, la aportación analiza la actual propuesta del gobierno municipal para recuperar las antiguas canalizaciones. Para ello, se revisan y discuten los objetivos del proyecto a escala urbana y metropolitana, junto al resto de problemáticas presentes en esta gran urbe del Norte de Italia.
Exploring Pre-Service Teachers’ Emotional Competence and Motivation for the Choice of a Teaching Career

The literature recognises the importance of teachers’ emotional competence for various aspects of the teaching profession, as well as the importance of attracting motivated and quality prospective teachers and retaining them in the profession. However, studies relating to the motivation to teach and some personal characteristics of prospective teachers are still relatively scarce. Therefore, this study aimed at contributing to this field of research by exploring the association between prospective teachers’ emotional competence and their motivation for the choice of a teaching career as proposed by the Factors Influencing Teaching (FIT)-Choice model. This study used a quantitative methodological approach. Prospective teachers who were enrolled in a primary school initial teacher education programme (N=423) participated in this study. The data were analysed using cluster analysis and multivariate analysis of variance. The results obtained revealed that the importance of almost all motives for the decision to pursue a teaching career, and the perception of demandingness of the teaching profession are rated higher by pre-service teachers with higher emotional competence. Finally, pre-service teachers with higher emotional competence also expressed a higher level of satisfaction with their career choice compared to those with a moderate level of emotional competence.

This paper focuses on assessing the immediate program graduate attributes and learning outcomes for the teacher preparation towards global competence initiatives. It describes the students' retrospection, which will serve as a basis for the program's strategic enhancement. This study employed a descriptive survey of 75 teacher candidates in the Philippines. Findings revealed that the top five highest program graduate attributes are lifelong learner, responsive teacher, ethical educator, subject matter expert, and multi-literate educator. Simultaneously, the bottom five are effective communicator, value-laden educator, instructional material developer, classroom manager, assessor and evaluator, and curriculum planner and implementer. Grade in experiential learning courses spelled the difference in the acquisition of graduate attributes. Implying that students with high academic performance perceived themselves to have a high level of acquisition of the Immediate Graduate Attributes (IGA). Retrospection of the respondents showed excellent satisfaction with the research and extension services, educational counseling program, and the instructors and professors' qualities while family and relatives were influential in choosing teaching as career preparation. Finally, parents' satisfaction and geographic locations are important factors that affect the teacher education program enrollment. This study will serve as reference in designing teacher education initiatives towards internationalization.

Con el objetivo de comparar la relación existente entre el contenido de fenoles totales, flavonoides y la capacidad antioxidante en las brácteas naranjas y moradas de Bougainvillea glabra Choisy, se obtuvieron extractos secos (ES) a partir de muestras de brácteas secas y molidas utilizando como disolvente una mezcla hidroalcohólica (50 %) y sonicación. Los contenidos promedios de fenoles totales (mg de EAG/g ES) y de flavonoides (mg EQ/g ES) resultaron ser los más altos en la variedad naranja. Se evaluó la capacidad antioxidante usando el método de la inhibición del radical libre 2,2-difenil-1-picrilhidrazilo (DPPH.), obteniéndose que las brácteas naranjas presentaron la mayor capacidad antioxidante, con una concentración inhibitoria del 50 % (CI50) promedio de 37 mg/mL, mientras que en la variedad morada el CI50 fue de 270 mg/mL. La correlación entre fenoles y flavonoides resultó ser altamente positiva, mientras que entre estos compuestos químicos y la capacidad antioxidante fue altamente negativa. Ambas muestras de B. glabra exhiben potencial antioxidante, siendo la superior en las brácteas de color naranja, y con relaciones significativas positivas (p<0,05) con los niveles de fenoles totales y flavonoides.
ARE LOCAL GOVERNMENTS OVERCONFIDENT WITH THE EFFECT OF BUDGET FORECAST ERRORS ON BUDGET DEVIATION?
Authors: Marundha Amor
Published: February 2021

This study aims to examine the effect of budget forecast errors on budget deviations moderated by local governments’ overconfidence. The research sample used regency/city governments in Indonesia during the 2017-2019 period. The analysis tool uses Eviews version 10 and SPSS version 22. The results showed that budget forecast errors had a positive and significant effect on budget deviation, but the local government’s overconfidence cannot cause an effect of budget forecast errors on the budget deviation. Additional test results of this study also showed that regency/city governments who were overconfident tend to fail in controlling their budget which could cause a surplus or deficit compared to local governments that were not overconfident. The same conditions apply to budget forecast errors. This means that regency/city governments that are overconfident tend to estimate budgets that are too high for revenue and/or budget estimates that are too low for expenditure compared to local governments that are not overconfident. Consistent with the main test results, this study shows that budget forecast errors have a significant effect on budget deviation and tend to occur in the Central Indonesian region category. Furthermore, overconfident regency/city governments cannot moderate the effect of budget forecast errors on budget deviations. Finally, these findings indicate that there is no difference between the budget forecast errors and the budget deviation in the three categories of western, central, and eastern Indonesia.
