Mutual learning in a tree parity machine and its application to cryptography

, 2002
Mutual learning of a pair of tree parity machines with continuous and discrete weight vectors is studied analytically. The analysis is based on a mapping procedure that maps the mutual learning in tree parity machines onto mutual learning in noisy ...

Structure‐Guided Engineering of a Cas12i Nuclease Unlocks Near‐PAMless Genome Editing

Advanced Science, EarlyView.
CRISPR‐Cas nucleases are limited by PAM requirements, restricting genome accessibility. Structure‐guided engineering of the compact Cas12i nuclease SF01 produced three variants with near‐PAMless, enabling efficient editing at diverse 5'‐NNTN‐3' sites. These nucleases expand the editable portion of the human genome more than fourfold, enabling efficient

Ecology and evolution of pyrazines in insects

Biological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Neural Network–Assisted Metasurface Retroreflector With Wide‐Angle Adaptivity

Electron, EarlyView.
This work proposes a wide‐angle, multi‐polarization, self‐sensing, and self‐adaptive intelligent metasurface retroreflector, with a planar profile and ultrathin thickness. By integrating a pre‐trained artificial neural network (ANN), the metasurface retroreflector can recognize the incident angle and promptly adapt to changes in the incoming wave.

Non-Repudiation in Internet Telephony

, 2007
We present a concept to achieve non-repudiation for natural language conversations over the Internet. The method rests on chained electronic signatures applied to pieces of packet-based, digital, voice communication.

Aloe vera in Food Preservation: Harnessing Bioactive Constituents for Clean‐Label Innovation and Safety Assurance

Food Safety and Health, EarlyView.
Aloe vera‐derived biopolymers and nanoformulations enhance antimicrobial, antioxidant, and barrier functions in clean‐label edible coatings and films, whereas safety‐critical anthraquinone thresholds and regulatory constraints shape their translational potential.

Employee Delight: Conceptualization, Antecedents, and Consequences

Human Resource Development Quarterly, EarlyView.
ABSTRACT This article examines the concept of employee delight as a distinct construct within organizational behavior. Based on a systematic literature review, we analyze 10 empirical studies that explicitly address this phenomenon. We propose a multidimensional conceptualization of employee delight as an affective state of highly positive valence and ...

Scale-Free Networks Generated By Random Walkers

, 2004
We present a simple mechanism for generating undirected scale-free networks using random walkers, where the network growth is determined by choosing parent vertices by sequential random walks. We show that this mechanism produces scale-free networks with

The effects of mindfulness‐based interventions on emotion regulation/dysregulation in people with mental health conditions: A systematic review and meta‐analysis

JCPP Advances, EarlyView.
Abstract Background We conducted a systematic review and meta‐analysis to examine the effects of mindfulness‐based interventions (MBIs) on emotion regulation (ER) and emotion dysregulation (ED) in people with any mental health condition. Methods Following a pre‐registered protocol (PROSPERO CRD42024618605), we searched multiple databases (Web of ...
