Assessment techniques to achieve learning outcomes in the speaking skill of 6th semester PINE major student at UPSE.
This thesis examines the assessment techniques used to achieve desired learning outcomes
in speaking skills among 6th-semester PINE major students at UPSE. It acknowledges the
paramount importance of effective speaking skills in language acquisition and the challenges
students face in their development. By conducting qualitative research, this study aims to shed
light on current assessment practices, identify areas for improvement, and assess their alignment
with intended learning outcomes and instructional strategies. The research objectives include
identifying existing assessment techniques, investigating perceptions of teachers and students
regarding their effectiveness, and analyzing the alignment between assessment techniques,
learning outcomes, and instructional strategies. Through these objectives, the study aims to
enhance students' oral proficiency and contribute to the improvement of assessment practices in
PINE courses. This research fills a crucial knowledge gap, providing insights into the use of
assessment techniques in promoting effective speaking skills and paving the way for enhanced
coherence and effectiveness in assessing students' oral proficiency
A Primer on Motion Capture with Deep Learning: Principles, Pitfalls and Perspectives
Extracting behavioral measurements non-invasively from video is stymied by
the fact that it is a hard computational problem. Recent advances in deep
learning have tremendously advanced predicting posture from videos directly,
which quickly impacted neuroscience and biology more broadly. In this primer we
review the budding field of motion capture with deep learning. In particular,
we will discuss the principles of those novel algorithms, highlight their
potential as well as pitfalls for experimentalists, and provide a glimpse into
the future.Comment: Review, 21 pages, 8 figures and 5 boxe
AmadeusGPT: a natural language interface for interactive animal behavioral analysis
The process of quantifying and analyzing animal behavior involves translating
the naturally occurring descriptive language of their actions into
machine-readable code. Yet, codifying behavior analysis is often challenging
without deep understanding of animal behavior and technical machine learning
knowledge. To limit this gap, we introduce AmadeusGPT: a natural language
interface that turns natural language descriptions of behaviors into
machine-executable code. Large-language models (LLMs) such as GPT3.5 and GPT4
allow for interactive language-based queries that are potentially well suited
for making interactive behavior analysis. However, the comprehension capability
of these LLMs is limited by the context window size, which prevents it from
remembering distant conversations. To overcome the context window limitation,
we implement a novel dual-memory mechanism to allow communication between
short-term and long-term memory using symbols as context pointers for retrieval
and saving. Concretely, users directly use language-based definitions of
behavior and our augmented GPT develops code based on the core AmadeusGPT API,
which contains machine learning, computer vision, spatio-temporal reasoning,
and visualization modules. Users then can interactively refine results, and
seamlessly add new behavioral modules as needed. We benchmark AmadeusGPT and
show we can produce state-of-the-art performance on the MABE 2022 behavior
challenge tasks. Note, an end-user would not need to write any code to achieve
this. Thus, collectively AmadeusGPT presents a novel way to merge deep
biological knowledge, large-language models, and core computer vision modules
into a more naturally intelligent system. Code and demos can be found at:

Egg-Phosphatidylcholine Attenuates T-Cell Dysfunction in High-Fat Diet Fed Male Wistar Rats
Obesity is associated with immune dysfunction including an impaired T-cell function characterized by a lower IL-2 (proliferation marker) production after stimulation. Phosphatidylcholine (PC), a form of choline mostly found in eggs, has been shown to beneficially modulate T-cell responses during the lactation period by increasing the production of IL-2. To determine the impact of egg-PC as part of a high-fat diet on immune function we randomly fed male Wistar rats one of three diets containing the same amount of total choline but differing in the form of choline: 1—Control low fat [CLF, 10% wt/wt fat, 100% free choline (FC)]; 2— Control high-fat (CHF, 25% wt/wt fat, 100% FC); 3— PC high-fat (PCHF, 25% wt/wt, 100% PC). After 9 weeks of feeding, rats were euthanized. Cell phenotypes and ex vivo cytokine production by splenocytes stimulated with phorbol 12-myristate 13-acetate plus ionomycin (PMA+I), lipopolysaccharide (LPS) and pokeweed (PWM) were measured by flow cytometry and ELISA, respectively. Rats fed the PCHF diet had a lower proportion of CD3+ cells when compared to both the CLF and the CHF. Following PMA+I stimulation, splenocytes from the CHF group produced less IL-2 and TNF-α compared to CLF and PCHF groups. No significant differences in cytokine production were found among groups after LPS and PWM stimulation. Our results show that feeding a high-fat diet impairs T-cell responses, as measured by ex vivo cytokine production, which can be attenuated by providing egg-PC
Plant biosystems design research roadmap 1.0
Human life intimately depends on plants for food, biomaterials, health, energy, and a sustainable environment. Various plants have been genetically improved mostly through breeding, along with limited modification via genetic engineering, yet they are still not able to meet the ever-increasing needs, in terms of both quantity and quality, resulting from the rapid increase in world population and expected standards of living. A step change that may address these challenges would be to expand the potential of plants using biosystems design approaches. This represents a shift in plant science research from relatively simple trial-and-error approaches to innovative strategies based on predictive models of biological systems. Plant biosystems design seeks to accelerate plant genetic improvement using genome editing and genetic circuit engineering or create novel plant systems through de novo synthesis of plant genomes. From this perspective, we present a comprehensive roadmap of plant biosystems design covering theories, principles, and technical methods, along with potential applications in basic and applied plant biology research. We highlight current challenges, future opportunities, and research priorities, along with a framework for international collaboration, towards rapid advancement of this emerging interdisciplinary area of research. Finally, we discuss the importance of social responsibility in utilizing plant biosystems design and suggest strategies for improving public perception, trust, and acceptance
Efficacy and safety of low-dose IL-2 in the treatment of systemic lupus erythematosus: A randomised, double-blind, placebo-controlled trial
Objectives Open-labelled clinical trials suggested that
low-dose IL-2 might be effective in treatment of systemic
lupus erythematosus (SLE). A double-blind and placebocontrolled trial is required to formally evaluate the safety and efficacy of low-dose IL-2 therapy.
Methods A randomised, double-blind and placebocontrolled
clinical trial was designed to treat 60 patients
with active SLE. These patients received either IL-2
(n=30) or placebo (n=30) with standard treatment
for 12 weeks, and were followed up for additional 12
weeks. IL-2 at a dose of 1 million IU or placebo was
administered subcutaneously every other day for 2 weeks
and followed by a 2-week break as one treatment cycle.
The primary endpoint was the SLE Responder Index-4
(SRI-4) at week 12. The secondary endpoints were other
clinical responses, safety and dynamics of immune cell
subsets.
Results At week 12, the SRI-4 response rates were
55.17% and 30.00% for IL-2 and placebo, respectively
(p=0.052). At week 24, the SRI-4 response rate of IL-2
group was 65.52%, compared with 36.67% of the
placebo group (p=0.027). The primary endpoint was not
met at week 12. Low-dose IL-2 treatment resulted in
53.85% (7/13) complete remission in patients with lupus
nephritis, compared with 16.67% (2/12) in the placebo
group (p=0.036). No serious infection was observed
in the IL-2 group, but two in placebo group. Besides
expansion of regulatory T cells, low-dose IL-2 may also
sustain cellular immunity with enhanced natural killer
cells.
Conclusions Low-dose IL-2 might be effective and tolerated in treatment of SThe work was supported by the National Natural Science Foundation
