Findings, published Jan. 17 in Cell Stem Cell, show that dopamine neurons infected with SARS-CoV-2 stop working and send out chemical signals that cause inflammation.
Normally, these neurons produce dopamine, a neurotransmitter that plays a role in feelings of pleasure, motivation, memory, sleep and movement.
Damage to these neurons is also connected to Parkinson’s disease.
“This project started out to investigate how various types of cells in different organs respond to …

SARS-CoV-2 infection causes dopaminergic neuron senescence
Yang and colleagues demonstrate that SARS-CoV-2 can infect hPSC-derived midbrain dopamine (DA) neurons and induce cellular senescence. Several drug candidates were identified to rescue SARS-CoV-2 infection and DA neuron senescence. Inflammation and cellular senescence were also identified in substantia nigra tissue of COVID-19 patients.

Near-Optimal Generalized Decoding of Polar-like Codes
We present a framework that can exploit the tradeoff between the undetected error rate (UER) and block error rate (BLER) of polar-like codes. It is compatible with all successive cancellation (SC)-based decoding methods and relies on a novel approximation that we call codebook probability. This approximation is based on an auxiliary distribution that mimics the dynamics of decoding algorithms following an SC decoding schedule. Simulation results demonstrates that, in the case of SC list (SCL) d…

I am working on a significant improvement to debug #Python code in #Jupyter notebooks:
It is based on the possibility to connect to a running Jupyter kernel from the command line and execute code in that context.
There, we can rerun the failing code and apply a custom excepthook to sta…

“Simply, there is no way to be cool,” [Pissed Jeans singer] Korvette concludes, “especially when you’ve hit a sixth album. We’re clearly not new; we’re old, we don’t care. It feels cool to not want to be cool. It’s the best. It’s the beauty of not feeling inclined to impress anyone, no need to show that you deserve anything, that you are punk or edgy. It’s embarrassing to try too hard. We're more comfortable in our own skin.”

Pissed Jeans Don’t Try Too Hard and Do Music For Fun | Feature Interview — POST-TRASH
During our 33-minute conversation, Matt Korvette, the 42-year-old vocalist of Pissed Jeans, says “fun” eleven times and “fan” six times. The Sub Pop mainstays out of Philadelphia dropped their sixth album, Half Divorced , and Korvette has it on repeat. Approaching two decades as a band, Pissed Jean

Ugh... got a call from the Vancouver honourary consul. Very nice lady. Proceeded to tell me I didn't send the right stuff... so I gotta do that over.
I just want it to be done. This not-going-to-Toronto thing is feeling a lot more complicated. It's not. But…
Ok, I'm done whining. Off to try to put everything needed together again! The right way this time!

Nebular Analysis of PNe NGC 3242
The work presented forms a part of the IASc-INSA-NASI Summer Research Fellowship (SRFP) project on the physical & chemical properties of planetary nebulae. Spectral observations of NGC3242 recorded using the VBT Observatory (IIA), Kavalur (TN) for orthogonal slit positions are used for the study. The spectral data were reduced and analyzed using the IRAF data analysis package following the standard procedure to obtain the one dimensional spectrum. Nebular Analysis is performed on the same using…

LINC: A Neurosymbolic Approach for Logical Reasoning by Combining Language Models with First-Order Logic Provers
Logical reasoning, i.e., deductively inferring the truth value of a conclusion from a set of premises, is an important task for artificial intelligence with wide potential impacts on science, mathematics, and society. While many prompting-based strategies have been proposed to enable Large Language Models (LLMs) to do such reasoning more effectively, they still appear unsatisfactory, often failing in subtle and unpredictable ways. In this work, we investigate the validity of instead reformulati…

Optimal control related to weak solutions of a chemotaxis-consumption model
In the present work we investigate an optimal control problem related to the following chemotaxis-consumption model in a bounded domain $Ω\subset \mathbb{R}^3$: $$\partial_t u - Δu = - \nabla \cdot (u \nabla v), \quad \partial_t v - Δv = - u^s v + f \,v\, 1_{Ω_c},$$ with $s \geq 1$, endowed with isolated boundary conditions and initial conditions for $(u,v)$, being $u$ the cell density, $v$ the chemical concentration and $f$ the control acting in the $v$-equation through the bilinear te…

A Review on the Analysis and Optimal Control of Chemotaxis-Consumption Models
In the present review we focus on the chemotaxis-consumption model $\partial_t u - Δu = - \nabla \cdot (u \nabla v)$ and $\partial_t v - Δv = - u^s v$ in $(0,T) \times Ω$, for any fixed $s \geq 1$, endowed with isolated boundary conditions and nonnegative initial conditions, where $(u,v)$ model cell density and chemical signal concentration. Our objective is to present an overview of the related literature and latest results on the aforementioned model concerning the following three distinct…
