About 40% of the proteins encoded in eukaryotic genomes are proteins of unknown function (PUFs). Their functional characterization remains one of the main challenges in modern biology. In this study we identified the PUF encoding genes from Arabidopsis (Arabidopsis thaliana) using a combination of sequence similarity, domain-based, and empirical approaches. Large-scale gene expression analyses ...

A polyurethane foam (PUF) sponge was mounted in a cassette sampler and evaluated as a sorbent for the collection of hexamethylene diisocyanate (HDI) monomer and HDI-based oligomers. Recovery studies indicated 112 +/- 34% average recovery of HDI monomer and 92 +/- 9% and 97 +/- 25% average recovery of HDI-based oligomers when using impregnated PUF sponges. The PUF sponge was also evaluated durin...

BACKGROUND The purpose of this study was to investigate possible healing effects of intraperitoneal (IP) mesenchymal stem cell (MSC) transplantation on ultrafiltration failure (UFF) in a chronic rat model of peritoneal dialysis (PD). METHODS Rats were initially divided into two groups. The APUF group received once-daily IP injections of 20 mL of 3.86% glucose PD solution for 6 weeks to stimul...

A PUF is a chip-unique challenge-response mechanism exploiting manufacturing process variation inside integrated circuits (ICs). It has many useful applications such as device authentication and secure, memory-less key storage. A mobile device can be authenticated using a PUF challenge-response pair. Moreover, a cryptographic key can be securely embedded in a mobile device using a PUF without a...

A novel strong physical unclonable function (PUF), called Probability-based PUF (Prob-PUF), is proposed using the stochastic process of trap emission in nano-scaled transistors. For first time, information probability used design. This new approach offers ideal immunity to machine learning (ML) attacks. Since Prob-PUF only stores a mathematical model, it naturally avoids dilemma between require...

Signals that promote germ cell self-renewal by preventing premature meiotic entry are well understood. However, signals that control mitotic proliferation to promote meiotic differentiation have not been well characterized. In Caenorhabditis elegans, GLP-1 Notch signalling promotes the proliferative fate by preventing premature meiotic entry. The germline niche cell, which is the source of the ...

A silicon physically unclonable function (PUF) using ring oscillators (ROs) has the advantage of easy application in both an application specific integrated circuit (ASIC) and a field-programmable gate array (FPGA). Here, we provide a RO-PUF using the initial waveform of the ROs based on 65 nm CMOS technology. Compared with the conventional RO-PUF, the number of ROs is greatly reduced and the t...

A Physical Unclonable Function (PUF) is a die specific random function that can be used in a number of secure IC applications including die identification/authentication and key generation. At the core of a silicon PUF is a circuit (the PUF core) that generates random bits. These bits are like a silicon biometric, unique across dies, but can be reliably reproduced multiple times on a die across...

Wireless sensors attracts increasingly attention from both academia and industry owing to emerging applications built upon them such as Internet of Things, smart home, E-Health, and etc. It becomes a concern that the sensed value should be trusted in such applications scenarios. The security of the sensor used to resort to traditional cryptographic techniques, which, however, only provides limi...

Weak uncloneable function (PUF) encryption key means that the manufacturer of the hardware can clone the key but anybody else is unable to so that. Strong uncloneable function (PUF) encryption key means that even the manufacturer of the hardware is unable to clone the key. In this paper, first we introduce an "ultra"-strong PUF with intrinsic dynamical randomness, which is not only not cloneabl...
