The NH3 thermal annealing and decoupled plasma nitridation (DPN) processes are compared for the equivalent oxide thickness (EOT) scaling of atomic-layer-deposited hafnium zirconate (HfZrO2) gate dielectric. Detailed physical, optical, and electrical characteristics of nitrided HfZrO2 (HfZrON) film are reported. It is found that DPN can yield a thinner SiOx interfacial layer (IL) (about 0.12 nm more in terms of EOT scaling)and a more densified HfZrO2 layer compared to those obtained using NH3 thermal annealing at a 16% nitrogen dose. NH3 thermal nitridation causes a large nitrogen distribution tail at the SiOx IL/Si substrate interface and increases leakage current, which suppresses EOT scalability.

The effects of the water extracts of Millettia reticulata Benth (WEMRB) and its active compound (protocatechuic acid [PCA]) on acute hepatic injury and inflammation in CCl4-induced Sprague-Dawley rats were investigated. Sprague-Dawley rats were orally treated with WEMRB or PCA for 28 consecutive days, and then the rats were given an intraperitoneal injection with CCl4. Pretreatment with WEMRB or PCA significantly lowered the CCl4-induced serum levels of hepatic enzyme markers (aspartate and alanine aminotransferases). Liver histopathology showed that WEMRB reduced the incidence of cytoplasmic vacuolization and necrosis induced by CCl4 in rats. Pretreatment with WEMRB also showed anti-inflammation on the expression of cyclooxygenase-2, inducible nitric oxide synthase, and myeloperoxidase, as well as nitrite and nitrate levels in the CCl4-induced Sprague-Dawley rats. The results suggest that oral administration of WEMRB decreases the hepatotoxic effects by increasing glutathione-dependent antioxidant enzyme activity, thereby reducing oxidative stress and inflammation in CCl4-induced Sprague-Dawley rats.

The effects of the water extracts of Millettia reticulata Benth (WEMRB) and its active compound (protocatechuic acid [PCA]) on acute hepatic injury and inflammation in $CCl_4$-induced Sprague-Dawley rats were investigated. Sprague-Dawley rats were orally treated with WEMRB or PCA for 28 consecutive days, and then the rats were given an intraperitoneal injection with $CCl_4$. Pretreatment with WEMRB or PCA significantly lowered the $CCl_4$-induced serum levels of hepatic enzyme markers (aspartate and alanine aminotransferases). Liver histopathology showed that WEMRB reduced the incidence of cytoplasmic vacuolization and necrosis induced by $CCl_4$ in rats. Pretreatment with WEMRB also showed anti-inflammation on the expression of cyclooxygenase-2, inducible nitric oxide synthase, and myeloperoxidase, as well as nitrite and nitrate levels in the $CCl_4$-induced Sprague-Dawley rats. The results suggest that oral administration of WEMRB decreases the hepatotoxic effects by increasing glutathione-dependent antioxidant enzyme activity, thereby reducing oxidative stress and inflammation in $CCl_4$-induced Sprague-Dawley rats.
Hybrid Genetic Algorithms for Solving Reentrant Flow-Shop Scheduling with Time Windows
Chettha Chamnanlor,Kanchana Sethanan,Chen-Fu Chien,Mitsuo Gen 대한산업공학회 2013 Industrial Engineeering & Management Systems Vol.12 No.4
The semiconductor industry has grown rapidly, and subsequently production planning problems have raised many important research issues. The reentrant flow-shop (RFS) scheduling problem with time windows constraint for harddisk devices (HDD) manufacturing is one such problem of the expanded semiconductor industry. The RFS scheduling problem with the objective of minimizing the makespan of jobs is considered. Meeting this objective is directly related to maximizing the system throughput which is the most important of HDD industry requirements. Moreover, most manufacturing systems have to handle the quality of semiconductor material. The time windows constraint in the manufacturing system must then be considered. In this paper, we propose a hybrid genetic algorithm (HGA) for improving chromosomes/offspring by checking and repairing time window constraint and improving offspring by leftshift routines as a local search algorithm to solve effectively the RFS scheduling problem with time windows constraint. Numerical experiments on several problems show that the proposed HGA approach has higher search capability to improve quality of solutions.

Background: Orthotopic organ transplantation, a treatment option for irreversible organ dysfunction according to organ failure, severe damaged organ or malignancy in situ, was usually accompanied with massive blood loss thus transfusion was required. We aimed to evaluate the adverse impact of blood transfusion on solid organ transplantation. Materials and Methods: From January, 2009 to December, 2014, patients who received orthotopic organ transplantation at Far Eastern Memorial Hospital medical center were enrolled. Clinical data regarding anemia status and red blood cell (RBC) transfusion before, during and after operation, as well as patient outcomes were collected for further univariate analysis. Results: A total of 105 patients who underwent orthotopic transplantation, including liver, kidney and small intestine were registered. The mean hemoglobin (Hb) level upon admission and before operation were $11.6{\pm}1.8g/dL$ and $11.7{\pm}1.7g/dL$, respectively; and the nadir Hb level post operation and the final Hb level before discharge were $8.3{\pm}1.6g/dL$ and $10.2{\pm}1.6g/dL$, respectively. The median units (interquartile range) of RBC transfusion in pre-operative, peri-operative and post-operative periods were 0 (0-0), 2 (0-12), and 2 (0-6) units, respectively. Furthermore, the median (interquartile range) length of hospital stay (LHS) from admission to discharge and from operation to discharge were 28 (17-44) and 24 (16-37) days, respectively. Both peri-operative and post-operative RBC transfusion were associated with longer LHS from admission to discharge and from operation to discharge. Furthermore, it increased the risk of post-operative septicemia. While peri-operative RBC transfusion elevated the risk of acute graft rejection in patients who received orthotopic transplantation. Conclusions: Worse outcome could be anticipated in those who had received massive RBC transfusion in transplantation operation. Hence, peri-operative RBC transfusion should be avoided as much as possible.

Atopic dermatitis (AD) is a chronic inflammatory skin disease, and its prevalence is increasing. AD usually elicits skin barrier dysfunction, dry skin and itching. As the mechanisms of AD remain unknown, there is an urgent need to find effective therapies. Because of the diversity and complexity of marine environments, the discovery of drugs from marine organisms as novel therapeutic agents for human diseases has seen renewed interest. Dihydroaustrasulfone alcohol (WA-25), the synthetic precursor of austrasulfone, which is a natural product isolated from a Formosan soft coral, has been shown to possess many therapeutic effects in our previous studies. However, the detailed mechanisms and therapeutic effects of WA-25 on AD are incompletely understood. We performed in vitro and in vivo studies to examine the effects of WA-25 on AD. We showed that WA-25 blocks inflammation and oxidative stress. Simultaneously, we also found that WA-25 reduces the AD scores and AD-induced transepidermal water loss (TEWL), scratching behavior, and alloknesis. WA-25 is more effective in cases of AD than are the drugs that are currently used clinically. Importantly, we also found that when nucleophosmin (NPM) was inhibited or when its expression was reduced, the anti-inflammatory and anti-AD effects of WA-25 were blocked. These data suggest that NPM plays dual roles in inflammation and AD. Overall, these results suggest that WA-25 is a potential anti-inflammatory and AD therapeutic agent that is modulated by NPM.

This paper presents our new intelligent interactive robot, which is constructed to eagerly provide multi-functional services in an office environment. In order to endow a full interactive capability of our robots for realizing so-called human-robot interaction (HRI), we propose sensor fusion based human detection and tracking system and human pose estimation to deal with a number of situations which may take place in the office environment. Not only by these perceptions, human interact with the robot also by some natural way, such as touching the interface screen and talking with the robot through microphone. Finally, the effectiveness of the proposed work is tested and validated by some of experiments.
