Summary: Mechanical computers have attracted significant research interest from nanoscale to macroscale as they can complement electronic computers, particularly in extreme environments. This study proposes a non-volatile nanomechanical bit based on the quasi-stable configurations of few-layer graphene with void defects. The researchers demonstrate multiple quasi-stable states and reprogrammability of this nanomechanical bit by deriving an analytic relationship for the void configuration. The study also explores the accuracy and stability of the nanomechanical bits based on few-layer graphene.

Summary: Dynamic symmetric searchable encryption (SSE) enables secure search and dynamic update of encrypted documents in a semi-trusted cloud server. Existing SSE schemes have privacy leaks, and none of them can preserve search pattern privacy or enhance backward privacy. In this article, a practical SSE scheme is proposed, which supports search pattern privacy and enhances backward privacy through an obfuscating technique, pseudorandom function, and pseudorandom generator. Security analysis and performance evaluations demonstrate the effectiveness and efficiency of the proposed scheme.

Summary: Embedding computation in biochemical environments using noncompetitive chemical reaction networks (NC-CRNs) has potential applications in various fields. The equilibria of NC-CRNs are robust to reaction rates and kinetic rate laws, making them suitable for rate-independent chemical computation. The translation from rectified linear unit (ReLU) neural networks to NC-CRNs is surprisingly compact, with a single bimolecular reaction corresponding to a single ReLU node. Numerical simulations demonstrate the feasibility of using NC-CRNs for tasks such as virus detection and spatial pattern formation.

Summary: This paper presents a novel and fast anti-collision algorithm called Monte-Carlo Query Tree Search (MCQTS), which combines the capabilities of traditional Monte-Carlo Tree Search and Query Tree. By applying heuristics on the tree traversal, this method increases the chance of encountering the most promising states. The collision mitigation based on MCQTS is validated in terms of time and space complexity and its performance is compared to conventional methods for multi-tag identification.

Summary: In this study, VSe2 nanosheets were synthesized using chemical vapor deposition and underwent a phase transition from 1T to 2H through annealing. The annealed VSe2 nanosheets exhibited reliable threshold switching (TS) behavior with good endurance, repeatability, and environmental stability. The VSe2 memristor demonstrated the ability to perform logic operations and simulate leaky integrate-and-fire (LIF) activity. This research provides a feasible approach to TS behaviors, expanding the applications of VSe2 materials and offering potential candidates for Boolean logic calculations and LIF functions.

Summary: Inspired by life's interaction networks, ongoing efforts are being made to increase the complexity and responsiveness of multicomponent interactions for sensing, control, and information processing. However, the easy and one-pot preparation of multimorphology nanomaterials has been overlooked. This study demonstrates that multimorphological silver nanomaterials (M-AgN) can form interaction networks with various analytes, enabling multimode and multianalyte colorimetric sensing and molecular information technology. The interaction of M-AgN with multianalytes not only induces multisignal responses but also allows for controllable reshaping of its four morphologies. By abstracting binary relationships between analytes and response signals, multicoding parallel logic operations can be performed, and molecular information encoding and hiding can be achieved.

Summary: Previous studies mainly used gas chromatography-mass spectrometry (GC-MS) to analyze volatile compounds in soy sauce. This study employed both GC-MS and headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS) to qualitatively and quantitatively analyze the volatile compounds in high-salt liquid-state fermentation soy sauce (HLFSS). The results revealed that there were 174 substances detected, with 87 detected by HS-GC-IMS and 127 by GC-MS. Aldehydes, ketones, esters, and alcohols were identified as the major compounds in HLFSS. Additionally, some compounds like ethyl pyruvate, (E)-2-pentenal, and diethyl propanedioate were newly detected using HS-GC-IMS.
