Synthesis of Pt Carbon Aerogel Electrocatalysts with Multiscale Porosity Derived from Cellulose and Chitosan Biopolymer Aerogels via Supercritical Deposition for Hydrogen Evolution Reaction

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The synthesis of platinumcarbon aerogel electrocatalysts with multiscale porosity derived from biopolymer aerogels via supercritical deposition is presented. The electrocatalysts demonstrate similar overpotentials to commercial alternatives with significantly higher platinum loadings, while exhibiting superior stability due to enhanced porosity ...

Photonic Crystal Fiber Based Wavelength-Tunable Optical Parametric Amplifier and Picosecond Pulse Generation

open access: yesIEEE Photonics Journal, 2014
We report a fiber optical parametric amplifier (FOPA) based on a photonic crystal fiber (PCF) with optimized dispersion and nonlinear properties pumped by a mode-locked ytterbium-doped fiber laser. Wavelength-tunable parametric gain bands can be obtained

An $L (1/3)$ Discrete Logarithm Algorithm for Low Degree Curves [PDF]

open access: yesarXiv, 2009
We present an algorithm for solving the discrete logarithm problem in Jacobians of families of plane curves whose degrees in $X$ and $Y$ are low with respect to their genera. The finite base fields $\FF_q$ are arbitrary, but their sizes should not grow too fast compared to the genus. For such families, the group structure and discrete logarithms can be

Generalised Weber Functions [PDF]

open access: yesarXiv, 2009
A generalised Weber function is given by $\w_N(z) = \eta(z/N)/\eta(z)$, where $\eta(z)$ is the Dedekind function and $N$ is any integer; the original function corresponds to $N=2$. We classify the cases where some power $\w_N^e$ evaluated at some quadratic integer generates the ring class field associated to an order of an imaginary quadratic field. We

Editorial (ENG)

open access: yesMateriales para la Historia del Deporte, 2023
Three years ago, back in December 2020, we were excited to launch the 20th issue of the journal Materials for Sports History [Spanish: Materiales para la Historia del Deporte (MHD)]. Since then, the issues from 21st to25th have been published. Among others, two monographics are included: one related to physical education, coordinated by Jean Saint ...

A Pilot Study to Evaluate Neurodevelopmental Outcomes in a Pediatric Cohort With Genodermatoses

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Our study aimed to evaluate cognitive function in individuals with genetic skin disorders involving neuroectoderm (n = 8) compared to individuals with only ectoderm or mesoderm (n = 16) involvement. We hypothesized that neuroectodermal involvement would result in poorer neurocognitive performance.

NLIP_Lab-IITH Low-Resource MT System for WMT24 Indic MT Shared Task [PDF]

open access: yesarXiv
In this paper, we describe our system for the WMT 24 shared task of Low-Resource Indic Language Translation. We consider eng $\leftrightarrow$ {as, kha, lus, mni} as participating language pairs. In this shared task, we explore the finetuning of a pre-trained model motivated by the pre-trained objective of aligning embeddings closer by alignment ...
