TL;DR: A physiological signal-based emotion recognition system is reported, developed to operate as a user-independent system, based on physiological signal databases obtained from multiple subjects, and consisted of preprocessing, feature extraction and pattern classification stages.
Abstract: A physiological signal-based emotion recognition system is reported. The system was developed to operate as a user-independent system, based on physiological signal databases obtained from multiple subjects. The input signals were electrocardiogram, skin temperature variation and electrodermal activity, all of which were acquired without much discomfort from the body surface, and can reflect the influence of emotion on the autonomic nervous system. The system consisted of preprocessing, feature extraction and pattern classification stages. Preprocessing and feature extraction methods were devised so that emotion-specific characteristics could be extracted from short-segment signals. Although the features were carefully extracted, their distribution formed a classification problem, with large overlap among clusters and large variance within clusters. A support vector machine was adopted as a pattern classifier to resolve this difficulty. Correct-classification ratios for 50 subjects were 78.4% and 61.8%, for the recognition of three and four categories, respectively.

TL;DR: In this paper, the authors constructed a new set of isochrones, called the Y2 Isochrones, that represent an update of the Revised Yale IsoChrones (RYI), using improved opacities and equations of state.
Abstract: We have constructed a new set of isochrones, called the Y2 Isochrones, that represent an update of the Revised Yale Isochrones (RYI), using improved opacities and equations of state. Helium diffusion and convective core overshoot have also been taken into consideration. This first set of isochrones is for the scaled solar mixture. A subsequent paper will consider the effects of α-element enhancement, believed to be relevant in many stellar systems. Two additionally significant features of these isochrones are that (1) the stellar models start their evolution from the pre-main-sequence birthline instead of from the zero-age main sequence and (2) the color transformation has been performed using both the latest table of Lejeune et al., and the older, but now modified, Green et al. table. The isochrones have performed well under the tests conducted thus far. The reduction in the age of the Galactic globular clusters caused by this update in stellar models alone is approximately 15% relative to RYI-based studies. When the suggested modification for the α-element enhancement is made as well, the total age reduction becomes approximately 20%. When post-RGB evolutionary stages are included, we find that the ages of globular clusters derived from integrated colors are consistent with the isochrone fitting ages.

TL;DR: In Korea, elevated fasting serum glucose levels and a diagnosis of diabetes are independent risk factors for several major cancers, and the risk tends to increase with an increased level offasting serum glucose.
Abstract: ContextDiabetes is a serious and costly disease that is becoming increasingly
common in many countries. The role of diabetes as a cancer risk factor remains
unclear.ObjectiveTo examine the relationship between fasting serum glucose and diabetes
and risk of all cancers and specific cancers in men and women in Korea.Design, Setting, and ParticipantsTen-year prospective cohort study of 1 298 385 Koreans (829 770
men and 468 615 women) aged 30 to 95 years who received health insurance
from the National Health Insurance Corp and had a biennial medical evaluation
in 1992-1995 (with follow-up for up to 10 years).Main Outcome MeasuresDeath from cancer and registry-documented incident cancer or hospital
admission for cancer.ResultsDuring the 10 years of follow-up, there were 20 566 cancer deaths
in men and 5907 cancer deaths in women. Using Cox proportional hazards models
and controlling for smoking and alcohol use, the stratum with the highest
fasting serum glucose (≥140 mg/dL [≥7.8 mmol/L]) had higher death rates
from all cancers combined (hazard ratio [HR], 1.29; 95% confidence interval
[CI], 1.22-1.37 in men and HR, 1.23; 95% CI, 1.09-1.39 in women) compared
with the stratum with the lowest level (<90 mg/dL [<5.0 mmol/L]). By
cancer site, the association was strongest for pancreatic cancer, comparing
the highest and lowest strata in men (HR, 1.91; 95% CI, 1.52-2.41) and in
women (HR, 2.05; 95% CI, 1.43-2.93). Significant associations were also found
for cancers of the esophagus, liver, and colon/rectum in men and of the liver
and cervix in women, and there were significant trends with glucose level
for cancers of the esophagus, colon/rectum, liver, pancreas, and bile duct
in men and of the liver and pancreas in women. Of the 26 473 total cancer
deaths in men and women, 848 were estimated as attributable to having a fasting
serum glucose level of less than 90 mg/dL. For cancer incidence, the general
patterns reflected those found for mortality. For persons with a diagnosis
of diabetes or a fasting serum glucose level greater than 125 mg/dL (6.9 mmol/L),
risks for cancer incidence and mortality were generally elevated compared
with those without diabetes.ConclusionIn Korea, elevated fasting serum glucose levels and a diagnosis of diabetes
are independent risk factors for several major cancers, and the risk tends
to increase with an increased level of fasting serum glucose.

TL;DR: The new guidelines include general management, special indications for liver biopsy in patients with persistently normal alanine aminotransferase, time to start or stop drug therapy, choice of drug to initiate therapy, when and how to monitor the patients during and after stopping drug therapy.
Abstract: Large amounts of new data on the natural history and treatment of chronic hepatitis B virus (HBV) infection have become available since 2005. These include long-term follow-up studies in large community-based cohorts or asymptomatic subjects with chronic HBV infection, further studies on the role of HBV genotype/naturally occurring HBV mutations, treatment of drug resistance and new therapies. In addition, Pegylated interferon α2a, entecavir and telbivudine have been approved globally. To update HBV management guidelines, relevant new data were reviewed and assessed by experts from the region, and the significance of the reported findings were discussed and debated. The earlier “Asian-Pacific consensus statement on the management of chronic hepatitis B” was revised accordingly. The key terms used in the statement were also defined. The new guidelines include general management, special indications for liver biopsy in patients with persistently normal alanine aminotransferase, time to start or stop drug therapy, choice of drug to initiate therapy, when and how to monitor the patients during and after stopping drug therapy. Recommendations on the therapy of patients in special circumstances, including women in childbearing age, patients with antiviral drug resistance, concurrent viral infection, hepatic decompensation, patients receiving immune-suppressive medications or chemotherapy and patients in the setting of liver transplantation, are also included.

TL;DR: A flexible and sensitive textile-based pressure sensor is developed using highly conductive fibers coated with dielectric rubber materials that exhibits superior sensitivity, very fast response time, and high stability when applied to make smart gloves and clothes that can control machines wirelessly as human-machine interfaces.
Abstract: A flexible and sensitive textile-based pressure sensor is developed using highly conductive fibers coated with dielectric rubber materials. The pressure sensor exhibits superior sensitivity, very fast response time, and high stability, compared with previous textile-based pressure sensors. By using a weaving method, the pressure sensor can be applied to make smart gloves and clothes that can control machines wirelessly as human-machine interfaces.
