Spindle cell variant of papillary thyroid carcinoma: A diagnostic challenge - A rare case report with brief review of literature
Authors: Khan Sabina , Hassan Mohammad Jaseem , Hameed Sayika , Jetley Sujata 
Published: December 2023

ABSTRACT

Objective:
Primary Spindle cell tumors of the thyroid are very rare and comprise a myriad of differential diagnoses ranging from reactive proliferations to neoplastic processes. Differentiation amongst these rare entities is of utmost importance as it defines the prognosis and also guides future therapy.

Case Report:
Hereby, we present a rare case of spindle cell variant of papillary thyroid carcinoma in a sixty-four-year-old female which posed a diagnostic challenge on histology. Microscopy showed a well-circumscribed spindle cell lesion with areas of infiltration and entrapment of colloid-filled thyroid follicles. There were no characteristic features of papillary carcinoma. A panel of immunohistochemistry markers was advised which clinched the diagnosis as the spindle tumor cells were positive for thyroid papillary carcinoma markers. Although papillary carcinoma usually has an indolent course, however interestingly this patient presented with lymph node metastasis one month after surgery which cytologically showed features of malignant spindle cell neoplasm.

Conclusion:
Through this case report we wish to highlight the cytological, histopathological as well as immunohistochemical features of this rare variant of papillary carcinoma.
Subcutaneous cellular angiofibroma of arm: A case report
Authors: Garach Niharika R. , Arora Khushboo C. , Waghoo Shazia , Kammar Praveen S. 
Published: December 2023

ABSTRACT
Cellular angiofibroma is a rare benign mesenchymal tumor reported in genital region in middle-aged patients. We report a rare presentation of the tumor in an extragenital location—the arm of a young male patient. After biopsy, an en bloc excision of the mass was done and diagnosis was confirmed. No adjuvant treatment was required. Our patient had an unusual location for this rare tumor at an age younger than reported in literature so far. Imaging can only predict the mesenchymal nature of the tumor but histopathology and immunohistochemistry (IHC) is the cornerstone of diagnosis. Cellular angiofibroma has a good prognosis. Histopathology and IHC are needed to confirm the diagnosis, hence emphasizing the role of a good and experienced pathologist. The pathogenesis of the cellular angiofibroma is still not fully determined and current hormonal and immunotherapy suppression regimes will need further evaluation.
Clique factors in pseudorandom graphs

Published: December 2023

An

n

-vertex graph is said to to be

(p,\beta)

-bijumbled
if for any vertex sets

A,B\subseteq V(G)

, we have

e(A,B)=p|A|\,|B|\pm \beta \sqrt{|A|\,|B|}.

We prove that for any

r\in {\mathbb N}_{\ge3}

and

c>0

there exists an

\varepsilon>0

such that any

n

(p,\beta)

-bijumbled graph with

n\in r \mathbb{N}

,

p>0

,

\delta(G)\geq cpn

and

\beta \leq \varepsilon p^{r-1}n

contains a

K_{r}

-factor. This implies a corresponding result for the stronger pseudorandom notion of

(n,d,\lambda)

-graphs. For the case of triangle factors, that is, when

r=3

, this result resolves a conjecture of Krivelevich, Sudakov and Szabó from 2004 and it is tight due to a pseudorandom triangle-free construction of Alon. In fact, in this case even more is true: as a corollary to this result and a result of Han, Kohayakawa, Person and the author, we can conclude that the same condition of

\beta=o(p^{2}n)

actually guarantees that a

(p,\beta)

G

contains every graph on

vertices with maximum degree at most 2.
Cohomology of the moduli of Higgs bundles on a curve via positive characteristic
Authors: de Cataldo Mark Andrea , Maulik Davesh , Shen Junliang , Zhang Siqing 
Published: December 2023

For a curve of genus

g

and any two degrees coprime to the rank, we construct a family of ring isomorphisms parameterized by the complex Lie group

\mathrm{GSp}(2g),

between the cohomology of the moduli spaces of stable Higgs bundles which preserve the perverse filtrations. As a consequence, we prove two structural results concerning the cohomology of Higgs moduli which are predicted by the P = W Conjecture in Non-Abelian Hodge Theory: (1) Galois conjugation for character varieties preserves the perverse filtrations for the corresponding Higgs moduli spaces. (2) The restriction of the Hodge–Tate decomposition for a character variety to each piece of the perverse filtration for the corresponding Higgs moduli space also gives a decomposition. Our proof uses reduction to positive characteristic and relies on the non-abelian Hodge correspondence in characteristic

Thinking ‘out of the box’ When Designing Formative Assessment Activities for the E-Portfolio
Authors: Majola Xolani Moffat 
Published: December 2023

E-Portfolios of on-line scholars are integral to instructional planning and the design of authentic, engaging, and active tutoring for periodic self/peer-and-instructor formative assessments. In addition, the formative assessment in open distance and e-learning (ODeL) is meant to provide and facilitate contact, support, and structure to the learning experiences of students who are often unfamiliar and alienated by the distance learning experience. Previous research has focused on formative assessment strategies, results, and feedback in distance learning, but little has been studied on how to design suitable formative assessment activities in this format. This article, therefore, presents findings of how lecturers can the design a formative assessment for e-portfolio activities for online learning. Ten lecturer participants were purposively sampled from three colleges within the ODeL university. These semi-structured interviews, together with an e-portfolio checklist formed the basis for the interpretative analysis of how formative assessment activities are designed for the e-portfolios. The lecturers are guided by the student’s learning outcomes and use sequential activities for students to do via the e-portfolio. This, therefore, involves the lecturer’s consideration of graded and non-graded formative assessment activities of individual and group work e-portfolios to provide evidence and make judgments about each student’s progress. This study’s findings emphasize the importance of designing formative assessment activities to help students learn the content and develop their understanding which further deepens their knowledge and acquisition of the module outcomes. The research shows that the benefits of optimal student engagement, performance, and learning are the result of the creative design of formative assessment activities.
Foundation Phase Educators’ Views on the Management of Professional Development in Historically Disadvantaged Schools

Published: December 2023

Foundation Phase (FP) educators are deemed productive when cohorts of learners who pass through their hands cope well with learning beyond the initial three grades of schooling. In South Africa, despite empirical evidence showing that FP educators in historically disadvantaged schools contend with overcrowded classes, low parental involvement and a shortage of teaching and learning resources, are still perceived as the primary source of poor learner achievement. The other point of view is that teacher underperformance and poor learner achievement are a legacy of the apartheid-engineered Bantu education policies that left the schooling system with poorly trained Black educators. To reverse these challenges, post-apartheid educational policies mandate that every school continuously conduct teacher professional development (TPD). Situated in the theory of change (ToC), this qualitative interpretivist study used interviews of a semi-structured nature to purposefully interact with a sample of six FP educators. They each characterised their HoDs’ management of TPD in two primary schools in Emalahleni Circuit 2, Mpumalanga Province. The second method of data collection entailed the analysis of a range of documents, namely the educators’ files, school performance improvement plans, and national education policy documents, to cross-check the findings of the thematic analysis. The findings revealed that HoDs were sufficiently collegial towards educators, showed commitment towards rendering professional support to educators, and adhered to a tight schedule of class visits to develop and appraise educators and monitor their implementation of inclusive education practices. Barriers stemmed from educators’ apprehension towards HoD’s class visits, especially the randomly conducted ones. The second barrier was the school management teams’ (SMTs’) inefficiency of professionalism, support for HoDs and understanding of curriculum leadership policy. The study recommends that communication around HODs’ scheduled and random class visits needs to take a more inclusive approach to scale down the panic caused by them, and SMTs must be equally prioritised for continuous professional development.

Authors: Терентьева А.Н. , Барабанов С.И. 
Published: December 2023

По опубликованным данным была рассмотрена популяция 39 метеоритообразующих тел. Из них были выбраны 4 объекта, орбиты которых расположены внутри орбиты Земли. Динамический параметр Тиссерана T j (возмущающая планета — Юпитер) указывает на их астероидное происхождение. Из астероидов NEO были отобраны те, что рас- положены внутри орбиты Земли. Таких оказалось 26 астероидов. Из популяции 26 астероидов, согласно критерию Саутворда-Хоккинса, найдены астероиды, которые могут быть связаны с метеоритообразующими телами. Предпола- гается, что эти тела могут быть осколками соответствующих астероидов. Делается вывод, что внутри орбиты Земли возможен постоянный источник образования метеоритообразующих тел.
According to the published data, the population of 39 meteorite producing bodies was considered. Of these, 4 objects were selected, whose orbits are located inside the Earth’s orbit. The dynamic parameter of the Tisserand T j (perturibing planet — Jupiter) indicates their asteroid origin. From near-Earth asteroids those were selected that reside inside the Earth’s orbit. There were 26 such asteroids. Of this population of 26 asteroids, according to the Southward-Hawkins criterion, asteroids have been found that may be associated with meteorite producing bodies. It is suggested that these bodies could be fragments of the corresponding asteroids. It is concluded that a constant source of formation of meteorite producing bodies is possible inside the Earth’s orbit.
Study of the impact of using the AOD1B model on the processing accuracy of DORIS measurements
Authors: Кузин С.П. 
Published: December 2023

В работе исследовано влияние применения модели AOD1B, учитывающей неприливные атмосферные и океанические возмущения, на точность обработки DORIS измерений. Для решения указанной задачи были обработаны DORIS данные в формате RINEX для десяти миссий системы DORIS (Cryosat2, HY2A, HY2C, HY2D, Jason2, Jason3, Saral, Sentinel3a, Sentinel3b, Sentinel6a), восемь из которых являются действующими и две миссии (Jason2 и HY2A) завер- шили свою работу. Интервал обработки для каждой действующей миссии составляет промежуток времени от начала миссии до конца 2022 г. Для проекта Jason2 интервал обработки составлял 2008.5–2019.8 гг., для проекта HY2A — 2011.8–2020.7 гг. Результаты исследования показывают, что использование модели AOD1B для всех десяти миссий совсем незначительно (менее 1%) уменьшает среднюю остаточную погрешность DORIS измерений. Таким образом, применение модели AOD1B при обработке DORIS измерений не оказывает существенного влияния на точность по- лучаемого решения в используемой стратегии обработки.
The paper investigates the effect of using the AOD1B model, which takes into account non-tidal atmospheric and oceanic disturbances, on the accuracy of processing DORIS measurements. To solve this problem, DORIS data were processed in RINEX format for ten missions of the DORIS system (Cryosat2, HY2A, HY2C, HY2D, Jason2, Jason3, Saral, Sentinel3a, Sentinel3b, Sentinel6a), eight of which are active and two missions (Jason2 and HY2A) have completed their work. The processing interval for each active mission is the time interval from the beginning of the mission to the end of 2022. For the Jason2 project, the processing interval was 2008.5–2019.8, for the HY2A project — 2011.8–2020.7. The results of the study show that using the AOD1B model for all ten missions reduces the mean residual error of DORIS measurements quite slightly (less than 1 percent). Thus, the application of the AOD1B model when processing DORIS measurements does not significantly affect on the accuracy of the resulting solution in the processing strategy used.

В работе выполнено исследование применения кватернионов при обработке DORIS измерений формата RINEX и про- ведена оценка влияния использования кватернионов на точность результатов обработки. Обработка данных с ис- пользованием кватернионов применялась для измерений спутников Jason2 и Jason3. Для проекта Jason2 интервал обработки составлял 2008.5–2019.8 гг., для проекта Jason3 — 2016.0–2023.0 гг. Результаты вычисления радиальной скорости между передатчиками и приемниками указанных миссий показывают незначительное уменьшение сред- ней остаточной погрешности радиальной скорости при использовании кватернионов (менее 1%). Таким образом, при используемой стратегии обработки DORIS измерений, использование кватернионов не оказывает существенного влияния на точность получаемого решения.
The paper investigates the use of quaternions in processing DORIS measurements of RINEX format and evaluates the impact of using quaternions on the accuracy of processing results. Data processing using quaternions was used for measurements of the Jason2 and Jason3 satellites. For the Jason2 project, the processing interval was 2008.5–2019.8, for the Jason3 project — 2016.0–2023.0. The results of the radial velocity calculation between the transmitters and receivers of these missions show a slight decrease in the average residual radial velocity error when using quaternions (less than 1 percent). Thus, with the DORIS measurement processing strategy used, the use of quaternions does not significantly affect on the accuracy of the resulting solution.

Published: December 2023

The study examined the impact of core competencies on organizational performance in Nigeria. It empirically investigated whether industrial goods firms in Nigeria enjoy sustained success by focusing on core competencies like their counterparts in developed economies as documented in some prior literature. Specifically, the study determined whether strong brand name, strong sales force, innovation, agility, and strong creative thinking as dimensions of core competencies impact on organizational performance. To address this objective, primary data was collected using structured questionnaire measured on Likert summated rating scale. A sample size of 200 employees drawn from selected industrial goods firms was used for the study. Descriptive statistics, correlation analysis, and multiple regression analysis were used to illuminate the data and test hypotheses. The results revealed that strong brand name, strong sales force, and strong creative thinking positively and significantly impact on organizational performance. Though innovation and agility have positive influence, but were not significant. Against this backdrop, it was recommended that management of industrial goods firms should leverage on core competencies to remain competitive in the global market space.
