Understanding Code Semantics: An Evaluation of Transformer Models in Summarization
This paper delves into the intricacies of code summarization using advanced
transformer-based language models. Through empirical studies, we evaluate the
efficacy of code summarization by altering function and variable names to
explore whether models truly understand code semantics or merely rely on
textual cues. We have also introduced adversaries like dead code and commented
code across three programming languages (Python, Javascript, and Java) to
further scrutinize the model's understanding. Ultimately, our research aims to
offer valuable insights into the inner workings of transformer-based LMs,
enhancing their ability to understand code and contributing to more efficient
software development practices and maintenance workflows.Comment: Accepted at GenBench, EMNLP 2023. All authors are co-first authors

PHOTOCATALYTICDEGRADATION OF RHODAMIN-B USING METAL COMPLEXES AND HYDROGEN PEROXIDE
ABSTRACT
The photocatalytic degradation has been considered to be an efficient process for degradation of organic
pollutants, which are present in the effluents released by industries. Thephotocatalytic bleaching was carried out on
rhodamin-B (cationic dye) in the presence of iron (III) complex, hydrogen peroxide and was observed
spectrophotometrically. The effect of various operating variables like pH, concentration of complex and dye, amount
of HzOzand light intensity etc. was also observed on the efficiency of the reaction. A tentative mechanism has also
been proposed for this photocatalytic degradation of rhodamin-B.

On Surgical Fine-tuning for Language Encoders
Fine-tuning all the layers of a pre-trained neural language encoder (either
using all the parameters or using parameter-efficient methods) is often the
de-facto way of adapting it to a new task. We show evidence that for different
downstream language tasks, fine-tuning only a subset of layers is sufficient to
obtain performance that is close to and often better than fine-tuning all the
layers in the language encoder. We propose an efficient metric based on the
diagonal of the Fisher information matrix (FIM score), to select the candidate
layers for selective fine-tuning. We show, empirically on GLUE and SuperGLUE
tasks and across distinct language encoders, that this metric can effectively
select layers leading to a strong downstream performance. Our work highlights
that task-specific information corresponding to a given downstream task is
often localized within a few layers, and tuning only those is sufficient for
strong performance. Additionally, we demonstrate the robustness of the FIM
score to rank layers in a manner that remains constant during the optimization
process.Comment: Accepted to EMNLP 202
WHO global research priorities for antimicrobial resistance in human health
The WHO research agenda for antimicrobial resistance (AMR) in human health has identified 40 research priorities to be addressed by the year 2030. These priorities focus on bacterial and fungal pathogens of crucial importance in addressing AMR, including drug-resistant pathogens causing tuberculosis. These research priorities encompass the entire people-centred journey, covering prevention, diagnosis, and treatment of antimicrobial-resistant infections, in addition to addressing the overarching knowledge gaps in AMR epidemiology, burden and drivers, policies and regulations, and awareness and education. The research priorities were identified through a multistage process, starting with a comprehensive scoping review of knowledge gaps, with expert inputs gathered through a survey and open call. The priority setting involved a rigorous modified Child Health and Nutrition Research Initiative approach, ensuring global representation and applicability of the findings. The ultimate goal of this research agenda is to encourage research and investment in the generation of evidence to better understand AMR dynamics and facilitate policy translation for reducing the burden and consequences of AMR

The photocatalytic bleaching was carried out on rhodamin-B (cationic dye) in the presence of iron (III) complex, hydrogen peroxide and was observed spectrophotometrically.

A tentative mechanism has also been proposed for this photocatalytic degradation of rhodamin-B.

Photocatalytic degradation of sunset yellow FCF in presence of some transition metal complexes and hydrogen peroxide
397-400The photocatalytic degradation of sunset yellow FCF by thiocyanate complexes of iron, copper and cobalt and hydrogen peroxide is reported here. The effect of different parameters, such as the pH, concentration of the complexes and dye, amount of Hâ‚‚Oâ‚‚ and light intensity on the rate of photocatalytic degradation has also been studied. The mechanism for degradation of the dye is also proposed
