Gemella morbillorum Promotes Colorectal Carcinogenesis: LPBDCP‐Mediated Invasion Activates Ras Signaling and Destabilizes p53

Advanced Science, EarlyView.
ABSTRACT Gut microbiota dysbiosis promotes colorectal cancer (CRC) tumorigenesis. A global fecal metagenomic analysis identified Gemella morbillorum as a key contributor to the CRC‐associated microbiota. Fluorescence in situ hybridization revealed that Gemella morbillorum is enriched in CRC tumor tissues compared to adjacent normal tissues.

Leveraging Artificial Intelligence and Large Language Models for Cancer Immunotherapy

Advanced Science, EarlyView.
Cancer immunotherapy faces challenges in predicting treatment responses and understanding resistance mechanisms. Artificial intelligence (AI) and machine learning (ML) offer powerful solutions for cancer immunotherapy in patient stratification, biomarker discovery, treatment strategy optimization, and foundation model development.

Multi-Party Computation with Omnipresent Adversary [PDF]

, 2009
Secure multi-party computation (MPC) protocols enable a set of n mutually distrusting participants P 1 , ..., P n , each with their own private input x i , to compute a function Y = F (x 1 , ..., x n ), such that at the end of the protocol, all participants learn the correct value of Y , while secrecy of the private inputs is maintained.

Large‐Scale Genomics Reveals Three‐Source Ancestry and Layered Adaptation to High Altitude in Tibetan Chickens

Advanced Science, EarlyView.
Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...

On Security Notions for Multi-Party Computation

, 2022
Die meisten Sicherheitsbegriffe, die heutzutage benutzt werden, stammen aus den 1980ern. Doch durch ein seitdem besseres Verständnis der Theorie stellt sich die Frage, ob sie nicht weiterentwickelt werden können. Ein begrenzender Faktor sind hierbei sogenannte Unmöglichkeitsbeweise, die mathematisch beweisen, welche Sicherheitsgarantien nicht erfüllt ...

Selective Interfacial Barriers Drive High‐Performance GeTe Thermoelectrics

Advanced Science, EarlyView.
Carrier‐phonon decoupling is the key to developing high‐performance thermoelectric materials. Here, we demonstrate that selective interfacial barriers can decouple carrier and phonon transport, thus achieving an exceptional peak ZT of ∼2.7 at 773 K, along with a record‐high average ZT of 1.9 across 300–773 K in the (Ge0.82Mn0.04Bi0.04Pb0.1Te)0.99(VSe2 ...

Modes of Operation Suitable for Computing on Encrypted Data

IACR Transactions on Symmetric Cryptology, 2017
We examine how two parallel modes of operation for Authenticated Encryption (namely CTR+PMAC and OTR mode) work when evaluated in a multiparty computation engine. These two modes are selected because they suit the PRFs examined in previous works.

Do Tax Incentives for Farmland Leases Increase Farm Supply? Evidence From Iowa's Beginning Farmer Tax Credit

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT In recent decades, agriculture has become increasingly concentrated through horizontal mergers and acquisitions via corporate entities, and policy makers are concerned this will be exacerbated by the aging population of farm operators. To reduce market concentration in agriculture, many states have enacted policies to entice new prospective ...
