The Demographic Indicators of Political Distrust and Action in Hong Kong

In recent years, Hong Kong has seen massive encroachment from Mainland China, resulting in Hong Kong’s own legislature introducing policy aimed at supporting Mainland Chinese authority in Hong Kong. As a result, Hong Kong has seen two large scale acts of political dissent, The Umbrella Movement/Occupy Central Movement in 2014, and the protests in response to an Extradition Bill in 2019. These events highlight that Hong Kong’s political landscape is shifting, and shifting fast. This study employs data provided by the World Values Survey to measure how measures of trust in state institutions and willingness to take political action have changed over the years, and along what demographic lines. Quantitative analysis shows that trust in state institutions has degraded over the last decade and a half, especially amongst younger, university-educated citizens with low prospects for upward mobility. Findings also show the same people who distrust the state are more likely to take confrontational political action, especially those within this group who identify as male. These findings provide a good indication of the trajectory of Hong Kong’s political landscape and raise concerns for China’s long term re-integration plans for Hong Kong

Detection Algorithms for Molecular MIMO

In this paper, we propose a novel design for molecular communication in which both the transmitter and the receiver have, in a 3-dimensional environment, multiple bulges (in RF communication this corresponds to antenna). The proposed system consists of a fluid medium, information molecules, a transmitter, and a receiver. We simulate the system with a one-shot signal to obtain the channel's finite impulse response. We then incorporate this result within our mathematical analysis to determine interference. Molecular communication has a great need for low complexity, hence, the receiver may have incomplete information regarding the system and the channel state. Thus, for the cases of limited information set at the receiver, we propose three detection algorithms, namely adaptive thresholding, practical zero forcing, and Genie-aided zero forcing.Comment: 6 pages, 6 figures, 2015 IEEE ICC accepte

PROFIT CONSISTENCY AND MANAGEMENT CHARACTERISTICS FOR SUCCESSFUL NORTH DAKOTA FARMS, 1995-2000

Farm profitability varies widely among producers, but the reasons for those differences are not clear as it is generally not known if the same farms are in the higher profit categories every year. Characteristics of the individual producer also vary substantially. Farm size, crop yields, cost of production, debt structure, and land ownership are some of the traits which differ among farms. This study analyzed farm finance data from the North Dakota Farm and Ranch Business Management Program over the years 1996-2000 to determine if the characteristics of profitable farms were different from the characteristics of farms which were not as profitable. A secondary objective was to evaluate if farms remained in similar profit quartiles every year.North Dakota Farm and Ranch Business Management Program, farm characteristics, return on assets, costs, land ownership, debt structure, Farm Management,

Resveratrol Prevents High Fluence Red Light-Emitting Diode Reactive Oxygen Species-Mediated Photoinhibition of Human Skin Fibroblast Migration.

BackgroundSkin fibrosis is a significant medical problem that leads to a functional, aesthetic, and psychosocial impact on quality-of-life. Light-emitting diode-generated 633-nm red light (LED-RL) is part of the visible light spectrum that is not known to cause DNA damage and is considered a safe, non-invasive, inexpensive, and portable potential alternative to ultraviolet phototherapy that may change the treatment paradigm of fibrotic skin disease.ObjectiveThe goal of our study was to investigate the how reactive oxygen species (ROS) free radicals generated by high fluence LED-RL inhibit the migration of skin fibroblasts, the main cell type involved in skin fibrosis. Fibroblast migration speed is increased in skin fibrosis, and we studied cellular migration speed of cultured human skin fibroblasts as a surrogate measure of high fluence LED-RL effect on fibroblast function. To ascertain the inhibitory role of LED-RL generated ROS on migration speed, we hypothesized that resveratrol, a potent antioxidant, could prevent the photoinhibitory effects of high fluence LED-RL on fibroblast migration speed.MethodsHigh fluence LED-RL generated ROS were measured by flow cytometry analysis using dihydrorhodamine (DHR). For purposes of comparison, we assessed the effects of ROS generated by hydrogen peroxide (H2O2) on fibroblast migration speed and the ability of resveratrol, a well known antioxidant, to prevent LED-RL and H2O2 generated ROS-associated changes in fibroblast migration speed. To determine whether resveratrol could prevent the high fluence LED-RL ROS-mediated photoinhibition of human skin fibroblast migration, treated cells were incubated with resveratrol at concentrations of 0.0001% and 0.001% for 24 hours, irradiated with high fluences LED-RL of 480, 640, and 800 J/cm2.ResultsHigh fluence LED-RL increases intracellular fibroblast ROS and decreases fibroblast migration speed. LED-RL at 480, 640 and 800 J/cm2 increased ROS levels to 132.8%, 151.0%, and 158.4% relative to matched controls, respectively. These LED-RL associated increases in ROS were prevented by pretreating cells with 0.0001% or 0.001% resveratrol. Next, we quantified the effect of hydrogen peroxide (H2O2)-associated ROS on fibroblast migration speed, and found that while H2O2-associated ROS significantly decreased relative fibroblast migration speed, pretreatment with 0.0001% or 0.001% resveratrol significantly prevented the decreases in migration speed. Furthermore, we found that LED-RL at 480, 640 and 800 J/cm2 decreased fibroblast migration speed to 83.0%, 74.4%, and 68.6% relative to matched controls, respectively. We hypothesized that these decreases in fibroblast migration speed were due to associated increases in ROS generation. Pretreatment with 0.0001% and 0.001% resveratrol prevented the LED-RL associated decreases in migration speed.ConclusionHigh fluence LED-RL increases ROS and is associated with decreased fibroblast migration speed. We provide mechanistic support that the decreased migration speed associated with high fluence LED-RL is mediated by ROS, by demonstrating that resveratrol prevents high fluence LED-RL associated migration speed change. These data lend support to an increasing scientific body of evidence that high fluence LED-RL has anti-fibrotic properties. We hypothesize that our findings may result in a greater understanding of the fundamental mechanisms underlying visible light interaction with skin and we anticipate clinicians and other researchers may utilize these pathways for patient benefit

2010 North Dakota Agricultural Outlook: Representative Farms, 2010-2019

Net farm income for most representative farms in 2019 is projected to be lower than in 2009. Low-profit farms, which comprise 20% of the farms in the study, may not have financial resiliency to survive without off-farm income. Commodity prices are expected to increase slowly from current levels. Commodity yields are projected to increase at historical trend-line rates and production expenses are expected to return to normal growth rates. Debt-to-asset ratios for all farms except for the low profit farm will decrease slightly throughout the forecast period. Debt-to-asset ratios for the low-profit farms are expected to increase to about 0.70.net farm income, debt-to-asset ratios, cropland prices, land rental rates, farm operating expenses, capitalization rate, risk., Agribusiness,

2004 NORTH DAKOTA AGRICULTURAL OUTLOOK: REPRESENTATIVE FARMS, 2004-2013

Net farm income for all representative farms in 2013 will be lower than in 2004. Low-profit farms, which comprise 25% of the farms in the study, may not have financial resiliency to survive without off-farm income. Costs are projected to increase faster than yields, which will pressure net farm income downward. Cropland prices and cash rental rates are projected to increase slightly in all regions. Debt-to-asset ratios for most farms will increase slightly throughout the forecast period. Debt-to-asset ratios for the low-profit and small-size farms are higher than those for large and high-profit farms.net farm income, debt-to-asset ratios, cropland prices, land rental rates, farm operating expenses, capitalization rate, Farm Management,
