SLITRK5 is differentially expressed in central nervous system metastasis in human breast cancer.
Authors: Mamoor Shahan
Published: September 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer (1-3). We mined published RNA-sequencing and microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that SLIT- and NTRK-like family member 5, encoded by SLITRK5, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. SLITRK5 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of SLITRK5 in primary tumors was correlated with overall, distant metastasis-free and recurrence-free survival. Modulation of SLITRK5 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.

The Silence of the LLMs: Cross-Lingual Analysis of Political Bias and False Information Prevalence in ChatGPT, Google Bard, and Bing Chat
Authors: Urman Aleksandra , Makhortykh Mykola
Published: September 2023

This article presents a comparative analysis of political bias in the outputs of three Large Language Model (LLM)-based chatbots - ChatGPT, Bing Chat, and Bard - in response to political queries concerning the authoritarian regime in Russia. We investigate whether safeguards implemented in these chatbots contribute to the censorship of information that is viewed as harmful by the regime, in particular information about Vladimir Putin and the Russian war against Ukraine, and whether these safeguards enable the generation of false claims, in particular in relation to the regime's internal and external opponents. To detect whether LLM safeguards reiterate political bias, the article compares the outputs of prompts focusing on Putin's regime and the ones dealing with the Russian opposition and the US and Ukrainian politicians. It also examines whether the degree of bias varies depending on the language of the prompt and compares outputs concerning political personalities and issues across three languages: Russian, Ukrainian, and English. The results reveal significant disparities in how individual chatbots withhold politics-related information or produce false claims in relation to it. Notably, Bard consistently refused to respond to queries about Vladimir Putin in Russian, even when the relevant information was accessible via Google Search, and generally followed the censorship guidelines that, according to Yandex-related data leaks, were issued by the Russian authorities. In terms of false claims, we find substantial variation across languages with Ukrainian and Russian prompts generating false information more often and Bard being more prone to produce false claims in relation to Russian regime opponents (e.g., Navalny or Zelenskyy) than other chatbots. This research aims to stimulate further dialogue and research on developing safeguards against the misuse of LLMs outside of democratic environments.

Communicated priors tune the perception of control
Authors: Blackburne George , Frith Chris D. , Yon Daniel
Published: September 2023

Action allows us to shape the world around us. But to act effectively we need to accurately sense what we can and cannot control. Classic theories across cognitive science suppose that this ‘sense of agency’ is constructed from the sensorimotor signals we experience as we interact with our surroundings. But these sensorimotor signals are inherently ambiguous, and can provide us with a distorted picture of what we can and cannot influence. Here we investigate one way that agents like us might overcome the inherent ambiguity of these signals: by combining noisy sensorimotor evidence with prior beliefs about control acquired through explicit communication with others. Using novel tools to measure and model control decisions, we find that explicit beliefs about the controllability of the environment alter both the sensitivity and bias of agentic choices; meaning that we are both better at detecting and more biased to feel control when we are told to expect it. These seemingly paradoxical effects on agentic choices can be captured by a computational model where expecting to be in control exaggerates the sensitivity or ‘gain’ of the mechanisms we use to detect our influence over our surroundings – making us increasingly sensitised to both true and illusory signs of agency. In combination, these results reveal a cognitive and computational mechanism that allows public communication about what we can and cannot influence to reshape our private sense of control.
Face and voice identity matching accuracy is not improved by multi-modal identity information
Authors: Smith Harriet M J , Ritchie Kay L. , Baguley Thom , Lavan Nadine
Published: September 2023

Identity verification from both faces and voices can be error-prone. Previous research has shown that faces and voices signal concordant information and cross-modal unfamiliar face-to-voice matching is possible, albeit often with low accuracy. In the current study, we ask whether performance on a face or voice identity matching task can be improved by using multimodal stimuli which add a second modality (voice or face). We find that overall accuracy is higher for face matching than for voices matching. However, contrary to predictions, presenting one unimodal and one multimodal stimulus within a matching task did not improve face or voice matching compared to presenting two unimodal stimuli. Additionally, we find that presenting two multimodal stimuli does not improve accuracy compared to presenting two unimodal face stimuli. Thus, multimodal information does not improve accuracy. However, intriguingly, we find that cross-modal face-voice matching accuracy predicts voice matching accuracy but not face matching accuracy. This suggests cross-modal information can nonetheless play a role in identity matching, and face and voice information combine to inform matching decisions. We discuss our findings in light of current models of person perception, and consider the implications for identity verification in security and forensic settings.

Quantifying the Flynn Effect in Spain, 1991–2022
Authors: Lasker Jordan
Published: September 2023

The Flynn effect is a topic of perennial interest to intelligence researchers, and it is one of the few pieces of intelligence research that has enjoyed considerable acclaim among the broader public. A recent study (Colom et al., 2023) purported to find a positive Flynn effect in Spain alongside considerable psychometric bias with respect to intercohort comparisons, suggesting that the Flynn effect based on observed score increases was misestimated. A reanalysis and reconsideration of that study’s data and results is performed and proffered. Modern methods for correcting scores for psychometric bias suggest that, depending on the choice of model, the Flynn effect in Spain has either been underestimated or reversed. At the same time, problems with sample selection make any conclusions about the Flynn effect or its reversal dubious.
Deficits, Crowding Out and Inflation in Monetarily Sovereign Nations
Authors: Dubey Rohan Ajay
Published: September 2023

Government deficits are often viewed negatively by mainstream economic theory. They are believed to lead to higher interest rates, inflation, and crowding out of private investment. This paper aims to evaluate the validity of these conventional beliefs about deficits. To do so, a Modern Monetary Theory and Keynesian theoretical framework have been used. These theories have then been analysed in the context of empirical data from the United States and Japan over the last three decades. I find that deficits have not directly led to higher interest rates, crowding out or inflation in these two nations. The findings emphasise the importance for monetarily sovereign governments to prioritise addressing socio-economic issues faced by citizens rather than being overly concerned about deficits on their own. The findings also indicate the need for a more pluralistic approach to macroeconomic policy that involves considering various schools of thought - such as Modern Monetary Theory - apart from mainstream economics, that may offer a more suitable framework for understanding fiscal policy choices and their respective outcomes.

Equilibrium Optimizer Based FOPID Control of BLDC Motor
Authors: TEMİR Ali , DURMUŞ Burhanettin
Published: September 2023

The main challenges of proportional integral derivative (PID) control are sudden set-point changes and parameter changes, which leads to poor response. It can be taken into account that this control unit can be replaced by another similar control unit, but it differs from it in the degree of integration and differentiation, and this is what is known as fractional-order PID (FOPID), which improves the performance of the system in the transient state. To choose the FOPID constants, various methodologies, including optimization algorithms, are used to obtain the best possible performance. In this paper, the speed of brushless DC motor (BLDC) was regulated using (FOPID), where the equilibrium optimizer (EO) algorithm was used to find the values of the controller constants, and the performance of this algorithm was compared with several other optimization algorithms such as particle swarm optimization (PSO), differential evolution (DE), and golden jackal optimization (GJO). Simulation results in Matlab-Simulink 2016a showed the effectiveness of the proposed algorithm (EO) in achieving response time, overshot, and lower steady state error compared with the rest of the algorithms.

This research was conducted to determine the exposure perceptions of employees working in a food production facility in Çanakkale to physical risk factors that they may encounter in their workplaces and to examine the relationship between these risk factors and the descriptive characteristics of employees. A questionnaire including sociodemographic characteristics and occupational risk factors was administered to a total of 400 business employees. SPSS 27.0 statistical package program was preferred in the analysis of the data. Statistical methods such as frequency, percentage, mean, standard deviation, t-test and ANOVA test were used to evaluate the data. The results were evaluated at 95% confidence interval and 5% significance level. The results show that employees have a high level of exposure perceptions regarding the physical risk factors they encounter in the workplace. Despite the training and precautions taken, it has been revealed that adequate measures are not taken for occupational risks in the working environment. It has been determined that the risk factors that the employees are exposed to differ according to age, gender, education level, education about occupational risks, knowledge about occupational risks and the level of precautions taken. However, it was concluded that the unit is not related to the working time.

Abstract
The problem behind this research is that there are still many Indonesian language teachers in Class X SMA Negeri 15 Padang having difficulty in analyzing the level of validity of the learning model that will be tested on Class X students at SMA Negeri 15 Padang. Besides that, the Indonesian Class X teacher of SMA Negeri 15 Padang has never conducted an analysis of the validity of the learning model that was tested on students. So that the Class X Indonesian teacher of SMA Negeri 15 Padang never knew what the support system was in implementing the learning model that would be tested on his students. So that the learning objectives cannot be achieved properly and optimally. This study aims to see the form of validity of the Sharing Reading Literacy Model and the level of validity of the valid Sharing Reading Literacy model that will be applied by the teacher to Class X students of SMA Negeri 15 Padang. This research is a development research that uses a Dick and Carey model. However, in this research, only up to the development stage (develop). The subject of this research is the validator team. Based on data analysis and discussion, it can be concluded that the content validation results are valid, namely . Content validation 60 with quite valid category. Meanwhile, the results of construct validation are classified as very valid, namely 100.

Reflecting Experiences on Using Blended Learning: A Self Narrative Inquiry Research
Authors: Farani Rizki
Published: September 2023

Blended learning (BL) has widely implemented in higher education setting. However, the application of BL presents a wide range of variation. BL is conducted based the consideration of modalities, methods and instruction. As the impact, each instructor has different strategies in applying BL. Therefore, it is important to explore BL practices in order to recognize strength and weakness of BL in different context. In this self-narrative inquiry research, I would like to narrate my personal experience in implementing BL on some theoretical courses in a bachelor program. The stories cover my BL practices from 2015 until 2019 which explain about modalities, methods and instructions selections. In narrating my stories, I highlight benefit and challenges of every BL practice to emphasize personal reflection from past, present and future events. By connecting three life events, I offer a reflection on how to select effective BL practice based on technical considerations, teaching strategies and instructional design. The reflection is expected to provide a reference for educators in designing blended learning for higher education.

OBJECTIVE

Meningiomas invading the intracranial venous sinuses may cause intracranial venous hypertension, papilledema, and visual compromise. Sinus resection and graft reconstructions, however, add significant complexity to tumor surgery, with the potential for increased morbidity. In this study, the authors explored whether venous sinus stenting might provide an alternative means of controlling venous hypertension that would be sustainable over the long term.

METHODS

The authors performed a retrospective review of all 16 patients with intracranial meningiomas who underwent stenting at their institution for venous sinus compromise. At presentation, all had headache and 9 had papilledema. Thirteen patients had 1 meningioma and 3 had 2 or more. Three patients had had previous tumor resection and radiotherapy. One patient had been treated with a lumboperitoneal shunt and radiotherapy. The median length of clinical follow-up was 8 years (range 4 months–18 years).

RESULTS

Venous sinus narrowing was often not confined to the site of meningioma, and bilateral transverse sinus narrowing, reminiscent of that seen in idiopathic intracranial hypertension, was present in 7 patients with sagittal sinus meningiomas. Eleven patients had stents placed solely across sinus narrowing caused by meningioma. Five patients had additional stents placed at other sites of venous narrowing at the same time: in one of these patients, a stent was placed across a defect in the sagittal sinus caused by previous surgery, and in the 4 other patients, stents were placed across nontumor narrowings of the transverse sinuses. In 1 patient, the jugular vein was also stented. Nine patients developed symptomatic in-stent restenosis at the meningioma site. Eight had further stenting procedures with variable success in restoring the in-stent lumen. The remaining patient, with a late partial relapse, is being reinvestigated. Papilledema resolved in all patients after stenting. Six patients experienced prolonged and very substantial relief of all symptoms. Five patients had persistent headache despite restoration of the sinus lumen. Five had persistent symptoms associated with resistant in-stent stenosis. There were no significant complications from any of the diagnostic or therapeutic procedures.

CONCLUSIONS

In patients who are symptomatic with meningiomas obstructing the venous sinuses, successful stenting of the affected segment can give a good outcome, especially in terms of relieving papilledema. However, further procedures are often necessary to maintain stent patency, other areas of venous compromise frequently coexist, and some patients remain symptomatic despite apparently successful treatment of the index lesion. Long-term surveillance is a requirement.
