Economic performance of pyrolysis of mixed plastic waste: Open-loop versus closed-loop recycling

, 2020
In recent decades new recycling technologies for mixed plastic waste have emerged. In pyrolysis, the polymer chains are thermally broken (pyrolyzed) to obtain hydrocarbon materials of different molecular weights such as naphtha, oil or waxes, whose ...

Closing loops without places

2010 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2010
This paper proposes a new topo-metric representation of the world based on co-visibility that simplifies data association and improves the performance of appearance-based recognition. We introduce the concept of dynamic bagof-words, which is a novel form of query expansion based on finding cliques in the landmark co-visibility graph.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Penerapan Kendali Fuzzy dalam Pengembangan Stimulasi Listrik untuk Mempercepat Penyembuhan Luka

Jurnal Nasional Teknik Elektro dan Teknologi Informasi
Penyembuhan luka kronis masih menjadi tantangan medis karena keterbatasan terapi konvensional dalam mempercepat regenerasi jaringan. Stimulasi listrik (electrical stimulation, ES) dapat menjadi solusi efektif, tetapi ES open-loop belum mampu menyesuaikan

Vibration Suppression and Over-Quadrant Error Mitigation Methods for a Ball-Screw Driven Servo System With Dual-Position Feedback

IEEE Access, 2020
For high-precision control in a ball-screw driven servo system, the full-closed loop position control structure with position measurements from both the drive side and the load side are usually required.

Model-Based Reinforcement Learning for Closed-Loop Dynamic Control of Soft Robotic Manipulators

IEEE Transactions on robotics, 2019
Dynamic control of soft robotic manipulators is an open problem yet to be well explored and analyzed. Most of the current applications of soft robotic manipulators utilize static or quasi-dynamic controllers based on kinematic models or linearity in the ...

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

MODERATE-DENSITY CLOSE-CLOSED LOOP BURST ERROR DETECTING CODES

Ratio Mathematica, 2003
In this paper, we study cyclic codes detecting a subclass of close-closed loop bursts viz. moderate-density close-closed loop bursts. A subclass of CT close-closed loop bursts called CT moderate-density close-closed loop bursts is also studied.

Closed loop peer review [PDF]

EMBO reports, 2018
EMBO Reports (2019) 20: e47437[OpenUrl][1][FREE Full Text][2] When preparing for that important interview or your big night out, you might first carefully select and then lay out and check your outfit. After spending far too much time making yourself look just so, you will then probably take a final review in the mirror before legging it for your taxi,
