Achieving snaky [PDF]

open access: yes, 2007
We prove that the polyomino generally known as snaky is a three-dimensional winner, that it loses on an 8 × 8 board, and that its handicap number is at most ...

Modified mean curvature flow of star-shaped hypersurfaces in hyperbolic space

open access: yes, 2010
We define a new version of modified mean curvature flow (MMCF) in hyperbolic space $\mathbb{H}^{n+1}$, which interestingly turns out to be the natural negative $L^2$-gradient flow of the energy functional defined by De Silva and Spruck in \cite{DS09}. We

Exploration and Practice of Carbon Sequestration Realized by CO2 Waterless fracturing

open access: yesEnergy Procedia, 2019
Carbon sequestration is an important measure to reduce greenhouse gas emissions. This paper introduces a new method of carbon sequestration using CO2 waterless fracturing technology. Based on the supporting technology system with independent intellectual

DOES THE VAT TAX EXPORTS?

open access: yesEconomic Inquiry, 2019
While a VAT should in principle be neutral with respect to international trade, it may in practice function as a tax on exporters' input purchases if firms receive incomplete VAT refunds.

Metabolic Recoding of NSUN2‐Mediated m5C Modification Promotes the Progression of Colorectal Cancer via the NSUN2/YBX1/m5C‐ENO1 Positive Feedback Loop

open access: yesAdvanced Science, Volume 11, Issue 28, July 24, 2024.
The RNA modification, 5‐methylcytosine (m5C), has recently gained prominence in regulating gene expression and tumorigenesis. This study identifies NSUN2 and YBX1 as the m5C “writer” and “reader” of ENO1 in colorectal cancer, culminating in a positive feedback loop involving the NSUN2/YBX1/m5C‐ENO1 signaling axis, thereby bridging the connection ...

Molecular basis of ribosome recognition and mRNA hydrolysis by the E. coli YafQ toxin

open access: yesNucleic Acids Research, 2015
Bacterial type II toxin-antitoxin modules are protein–protein complexes whose functions are finely tuned by rapidly changing environmental conditions. E. coli toxin YafQ is suppressed under steady state growth conditions by virtue of its interaction with

KMT2D‐mediated H3K4me1 recruits YBX1 to facilitate triple‐negative breast cancer progression through epigenetic activation of c‐Myc

open access: yesClinical and Translational Medicine, Volume 14, Issue 7, July 2024.
YBX1 is a “reader” of KMT2D‐mediated H3K4me1 mark. YBX1 and KMT2D activate the expression of SENP1 and c‐Myc. YBX1 is recruited by H3K4me1 mark to facilitate breast cancer progression. Abstract Background Lysine methyltransferase 2D (KMT2D) mediates mono‐methylation of histone H3 lysine 4 (H3K4me1) in mammals.

Hawaiian Volcanic Ash, an Airborne Fomite for Nontuberculous Mycobacteria

open access: yesGeoHealth, Volume 8, Issue 1, January 2024.
Abstract Nontuberculous mycobacteria (NTM) are environmentally acquired opportunistic pathogens that can cause chronic lung disease. Within the U.S., Hawai'i shows the highest prevalence rates of NTM lung infections. Here, we investigated a potential role for active volcanism at the Kīlauea Volcano located on Hawai'i Island in promoting NTM growth and ...

Toward a hybrid integrated translation environment [PDF]

open access: yes, 2002
In this paper we present a model for the future use of Machine Translation (MT) and Computer Assisted Translation. In order to accommodate the future needs in middle value translations, we discuss a number of MT techniques and architectures.

BMSSM Higgs Bosons at the Tevatron and the LHC [PDF]

open access: yes, 2010
We study extensions of the Minimal Supersymmetric Standard Model (MSSM) with new degrees of freedom that couple sizably to the MSSM Higgs sector and lie in the TeV range.
