“…This biphasic behavior is explained by the initially rapid desorption of the drug that coats the surface of the NPs . After that, the slower release is a result from the hydrolysis of PLGA in the aqueous environment, a complex process comprising the polymeric erosion of NPs and/or relaxation of polymer chains, along with the diffusion of the drug from within the NPs . In comparison to Run 08, Run 01 was able to release higher amounts of CUR at each time, variation that increased noticeably after the 12 h burst; thereby reassuring that greater EE is of interest for therapies that demand administration of greater net doses of drugs.…”

Curcumin (CUR) is one natural bioactive compound acknowledged for diverse therapeutic activities, but its use is hindered by its poor bioavailability, fast metabolism, and susceptibility to pH variations and light exposure. Thus, the encapsulation in poly(lactic-co-glycolic acid), or PLGA, has been successfully used to protect and enhance CUR absorption in the organism, making CUR-loaded PLGA nanoparticles (NPs) promising drug delivery systems. However, few studies have focused beyond CUR bioavailability, on the environmental variables involved in the encapsulation process, and whether they could help obtain NPs of superior performance. Our study evaluated pH (3.0 or 7.0), temperature (15 or 35 °C), light exposure, and inert atmosphere (N2) incidence in the encapsulation of CUR. The best outcome was at pH 3.0, 15 °C, without light incidence, and without N2 usage. This best nanoformulation showed NP size, zeta potential, and encapsulation efficiency (EE) of 297 nm, −21 mV, and 72%, respectively. Moreover, the CUR in vitro release at pH values 5.5 and 7.4 suggested different potential applications for these NPs, one of which was demonstrated by the effective inhibition of multiple bacteria (i.e., Gram-negative, Gram-positive, and multi-resistant) in the minimal inhibition concentration assay. Besides, statistical analyses confirmed a significant impact of temperature on the NP size; in addition, temperature, light, and N2 affected the EE of CUR. Thus, the selection and control of process variables resulted in higher CUR encapsulation and customizable outcomes, ultimately enabling more economical processes and providing future scale-up guidelines.

“…Below, we study robustness of 1687 networks with respect to the changes in access scenario (i.e., change in the number of accesses and the access schedule), and compare seven network design approaches regarding OAT, hardware overhead, and robustness. The complete study can be found in [6].…”

“…That is, when the sensor and debugging instruments are not needed, their corresponding shift-registers and dedicated SIBs are excluded by programming SIB 2 to be closed. To construct a hierarchical network optimized for multiple scenarios, [6] uses an adaptation of the method in [5] (which was proposed for a single scenario with sequential access schedule).…”

Abstract-IEEE 1687 (IJTAG) has been developed to enable flexible and automated access to the increasing number of embedded instruments in today's integrated circuits. These instruments enable efficient post-silicon validation, debugging, wafer sort, package test, burn-in, bring-up and manufacturing test of printed circuit board assemblies, power-on self-test, and in-field test. Current paper presents an overview of challenges as well as selected examples in the following topics around IEEE 1687 networks: (1) design to efficiently access the embedded instruments, (2) verification to ensure correctness, and (3) fault management at functions performed in-field through the product's life time.

“…This involved, for example, the analysis if the network topology of an ICL network is functionally correct and conclusive (related to IEEE 1687 standards). New efficient and scalable approaches for sophisticated network analysis have been developed [ZAD14a], [ZAD14b], [ZAD16a]. The set of subtasks addressed contained, for example, the adaption of network topologies and mechanisms to support modular test as well as optimizing IEEE 1687 topologies with respect to requirements coming from the monitoring tasks and fault tolerant operation [JUT16a].…”

This is an overview paper that motivates and describes performed work done in the European Commission funded research project BASTION, which focuses on two critical problems of modern electronics: the No-Fault-Found (NFF) and CMOS ageing. New defect classes contributing to NFF have been identified, including timing related faults (TRF) at board level and intermittent resistive faults (IRF) at IC level. BASTION has addressed the mechanisms of ageing and developed several techniques to improve the longevity of electronic products. Embedded Instrumentation, monitors, and IEEE 1687 standard for reconfigurable scan networks (RSN) are seen as an important leverage that helped mitigating the impact of the above listed problems by facilitating a low-latency, scalable online system health monitoring and error localization infrastructure as well as integration of all heterogeneous technologies into a homogeneous demonstration platform. This paper helps the reader to get a general overview of the work performed and provides a collection of references to publications where the respective research results are described in detail.
