A comparison of posture and muscle activity during tablet computer, desktop computer and paper use by young children (2008)

Computers are now widely used by children. Tablet computers are becoming widely available and promoted for use by school children. The primary objective of this study was to compare the posture and muscle activity of children using a tablet computer to the posture and muscle activity of children using a desktop computer and paper technology. Eighteen children (mean age 5.6 years) performed a colouring-in task in tablet, desktop and paper conditions. 3-D posture and muscle activity around the neck and shoulder was assessed. Tablet computer use was similar to paper use, with less neutral spinal posture, more elevated scapular posture and greater upper trapezius and cervical erector spinae activity. This was offset by greater variability of posture and muscle activity. Tablet computer use clearly results in different musculoskeletal stresses than desktop computer use. Computer use guidelines need to be appropriate to traditional and emerging technologies. Tablet computers are being promoted for use by adults and children. However, the physical impact of using this type of technology is not known. The findings of this study provide the first tablet-specific evidence to inform guidelines on wise use of tablet computers by children.
Batch transfer of LIGA microstructures by selective electroplating and bonding (2002)

A flip-chip, batch tranfer process for LIGA microstructures has been demonstrated be selected electroplating and bonding. The bonding process is achieved by filling electroplated nickel in the gap of two bonding substrates, a LIGA and an IC (Integrated Circuit) chip. The electroplating solution is set at a temperature of 50/spl deg/C and with current density of 68.3 A/m/sup 2/. It is found that a total electroplating time of 80 minutes is required for the completion of the bonding process and that all the targeted LIGA microstructures are bonded and transferred to the IC substrate. Experimentally, a LIGA gripper based on the principle of self-heating and thermal expansion is successfully transferred and operated. When a maximum input current of 1.6 A is applied, a displacement of 90 /spl mu/m is observed. This flip-chip assembly process enables a new class of integrated electro-mechanical manufacturing for microelectromechanical devices.
A Group of Sixth Dynasty Titles Relating to Ptah and Sokar (1964)

in the Bulletin of the University Museum in Philadelphia, where it has long been exhibited,2 it remains to be pointed out that the titles on the six jambs form a rare and interesting group, which, when studied in relation to each other, contribute a surprising amount of information on the development of the local priesthoods from the Old to the Middle Kingdom. This is not to say that the false door belongs to the Intermediate Period; although its form and content show that it cannot be
Extreme learning machine with multiple kernels (2013)

Recently a novel learning algorithm called extreme learning machine (ELM) was proposed for efficiently training single-hidden layer feedforward neural networks (SLFNs). Compared with other traditional gradient-descent-based learning algorithms, ELM has shown promising results because it chooses weights and biases of hidden nodes randomly and obtains the output weights and biases analytically. In most cases, ELM is fast and presents good generalization, but we find that the stability and generalization performance still can be improved. In this paper, we propose a hybrid model which combines the advantage of ELM and the advantage of Bayesian “sum of kernels” model, named Extreme Learning Machine with Multiple Kernels (MK-ELM). This method optimizes the kernel function using a weighted sum of kernel functions by a prior knowledge. Experimental results show that this approach is able to make neural networks more robust and generates better generalization performance for both regression and classification applications.

Trust: The Social Virtues and the Creation of Prosperity (1996)

In his bestselling The End of History and the Last Man, Francis Fukuyama argued that the end of the Cold War would also mean the beginning of a struggle for position in the rapidly emerging order of 21st-century capitalism. In Trust, a penetrating assessment of the emerging global economic order after History, he explains the social principles of economic life and tells us what we need to know to win the coming struggle for world dominance. Challenging orthodoxies of both the left and right, Fukuyama examines a wide range of national cultures in order to divine the underlying principles that foster social and economic prosperity. Insisting that we cannot divorce economic life from cultural life, he contends that in an era when social capital may be as important as physical capital, only those societies with a high degree of social trust will be able to create the flexible, large-scale business organizations that are needed to compete in the new global economy. A brilliant study of the interconnectedness of economic life with cultural life, Trust is also an essential antidote to the increasing drift of American culture into extreme forms of individualism, which, if unchecked, will have dire consequences for the nation's economic health.

Studies on adjuvant‐induced polyarthritis in rats. I. Adjuvant composition, route of injection, and removal of depot site (1962)

Abstract The composition and quantity of Freund‐type adjuvant injected, the route of injection, and reaction at the depot site were studied for their roles in producing polyarthritis in rats. The intra‐dermal injection of Myobacterium butyricum in oil induced arthritis with much higher frequency than the subcutaneous or intravenous route. The minimal effective intradermal dose was 0.06 mg. M. butyricum in 0.02 ml. oil; 0.6 mg. mycobacteria in 0.1 ml. oil was required to produce polyarthritis in 100 per cent of rats. Wax fractions of mycobacteria did not induce arthritis. Neither a depot of adjuvant nor inflammation at the injection site was important as polyarthritis developed, even though amputation of the tail to remove the depot of injected adjuvant was performed within 2 hours after injection. While the mechanism of adjuvant‐induced polyarthritis remains unknown, the joint disease appeared dependent upon specific sites of dissemination of the adjuvant.
Design of a DC/DC buck converter for ultra-low power applications in 65nm CMOS Process (2012)

Switching mode DC/DC converters are critical building blocks in portable devices and hence their power efficiency, accuracy and cost are a major issue. The primary focus of this thesis is to address these critical issues.This thesis focuses on the different methods of feedback control loop which are employed in the switching mode DC/DC converters such as voltage mode control and current mode control. It also discusses about the structure of buck converter and tries to find an efficient solution for stepping-down the DC voltage level in ultra-low power applications. Based on this analysis, a 20 MHz voltage mode DC/DC buck converter with an on-chip compensated error amplifier in 65 nm CMOS process is designed and implemented.The power efficiency has been improved by sizing the power switches to have a low parasitic output and gate capacitances to reduce the capacitive and gate-drive losses. Also the error amplifier biasing current is chosen a small value (12.5 μA) to reduce the power dissipations in the control loop of the system. The maximum 84% power efficiency is achieved at 1.1 V to 500 mV conversion, above 81% efficiency can be achieved at load current from 0.5 mA to 1.26 mA. Due to wide bandwidth error amplifier and proper compensation network the fast transient response with settling time around 45 μs is achieved.
Reliability of a smartphone-based goniometer for knee joint goniometry (2012)

The aim of this study was to assess the reliability of a smartphone-based application developed for photographic-based goniometry, DrGoniometer (DrG), by comparing its measurement of the knee joint angle with that made by a universal goniometer (UG). Joint goniometry is a common mode of clinical assessment used in many disciplines, in particular in rehabilitation. One validated method is photographic-based goniometry, but the procedure is usually complex: the image has to be downloaded from the camera to a computer and then edited using dedicated software. This disadvantage may be overcome by the new generation of mobile phones (smartphones) that have computer-like functionality and an integrated digital camera. This validation study was carried out under two different controlled conditions: (i) with the participant to measure in a fixed position and (ii) with a battery of pictures to assess. In the first part, four raters performed repeated measurements with DrG and UG at different knee joint angles. Then, 10 other raters measured the knee at different flexion angles ranging 20-145° on a battery of 35 pictures taken in a clinical setting. The results showed that inter-rater and intra-rater correlations were always more than 0.958. Agreement with the UG showed a width of 18.2° [95% limits of agreement (LoA)=-7.5/+10.7°] and 14.1° (LoA=-6.6/+7.5°). In conclusion, DrG seems to be a reliable method for measuring knee joint angle. This mHealth application can be an alternative/additional method of goniometry, easier to use than other photographic-based goniometric assessments. Further studies are required to assess its reliability for the measurement of other joints.

Synthesis of 1.4-naphthoquinones-4-aryl(aroyl)hydrazones of potential antimicrobial activity. (1976)

The isolation of phthiocol (3-hydroxy-2-methyl-1.4-naphthoquinone) from the acetone-soluble fat fraction of tubercle bacilli [1, 2] and the confirmation that it had antituberculous activity against H-37 R.V. strain [20] in vitro and in mice [12], prompted the synthesis of some 2-alkyl-3-hydroxy-1.4-naphthoquinone-4-aryl(aroyl)hydrazones as possible tuberculostatic agents.
Some Observations on Colour Fastness to Washing with Particular Reference to Disperse Dyes on Polyester (1975)

In recent years there has been a trend away from the traditional soap‐based washing tests towards methods based on commercial‐type washing powders. Experience with tests based on washing powders, and the relationship between these tests and the traditional soap‐based tests, are described. It is shown that the degree of staining of adjacent fabrics, particularly nylon, increases as the detergent concentration in the wash liquor is decreased. Post‐stentering and the quality of fabrics used as adjacents in the wash test can have a considerable influence on the results.
Improved thermal stability and mechanical properties of poly(propylene carbonate) by reactive blending with maleic anhydride (2011)

Abstract To extend the application of a carbon dioxide sourced environmental friendly polymer: poly (propylene carbonate) (PPC), a small amount of maleic anhydride (MA) was melt blended to end‐cap with PPC to improve its thermal stability and mechanical properties. Thermal and mechanical properties of end‐capped PPC were investigated by TGA, GPC, mechanical test, and DMA. TGA and titration results demonstrate that PPC can be easily end‐capped with MA through simple melt blending. TGA results show that the thermal degradation temperature of PPC could be improved by around 140°C by adding MA. GPC measurement indicates that the molecular weight of PPC can be maintained after blending with MA, where pure PPC experiences a dramatic degradation in molecular weight during melt process. More importantly, the tensile strength of PPC after blending with MA was found to be nearly eight times higher than that of pure PPC. It has approached the mechanical properties of polyolefin polymers, indicating the possibility of replacing polyolefin polymers with PPC for low temperature applications. The method described here could be used to extend the applications of PPC and fight against the well known global warming problem. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Optimum Path Planning for Multi-robot H-beam Cutting System (2011)

Optimum path planning for multi-robot H-beam cutting system is presented to improve work efficiency. According to the working and design features of the multiple robots system, the minimum time delay method is adopted to avoid collision, and collision avoidance and path planning can be abstracted to a mathematical model to be optimized. Fast collision detection for the system is put forward based on analyzing the mode of collision. The concepts of collision map and interference zones are introduced and mathematic model of optimum path planning is constructed based on interference zones to compute the minimum delay time. We use the off line programming to compute the delay time and build database of optimum paths for all of cutting types. From the simulation result of a cutting type of H-beam, we can achieve the goal of improving work efficiency through the optimized path.

Psychotic Symptoms in Adolescence Index Risk for Suicidal Behavior (2012)

CONTEXT Recent evidence from both clinical and population research has pointed to psychotic symptoms as potentially important markers of risk for suicidal behavior. However, to our knowledge, there have been no epidemiological studies to date that have reported data on psychotic symptoms and suicidality in individuals who have been clinically assessed for suicidal behavior. OBJECTIVES To explore associations between psychotic symptoms in nonpsychotic adolescents and risk for suicidal behavior in (1) the general population, (2) adolescents with psychiatric disorder, and (3) adolescents with suicidal ideation. DESIGN Two independently conducted case-control clinical interview studies. SETTING Population-based studies in Ireland. PARTICIPANTS Study 1 included 212 adolescents aged 11 to 13 years. Study 2 included 211 adolescents aged 13 to 15 years. Participants were recruited from schools. MAIN OUTCOME MEASURES Suicidal behavior and psychotic symptoms, assessed by semi-structured diagnostic clinical interview. RESULTS Psychotic symptoms were associated with a 10-fold increased odds of any suicidal behavior (ideation, plans, or acts) in both the early and middle adolescence studies (odds ratio [OR], 10.23; 95% CI, 3.25-32.26; P < .001 and OR, 10.5; 95% CI, 3.14-35.17; P < .001, respectively). Adolescents with depressive disorders who also experienced psychotic symptoms were at a nearly 14-fold increased odds of more severe suicidal behavior (suicide plans and suicide acts) compared with adolescents with depressive disorders who did not experience psychotic symptoms (OR, 13.7; 95% CI, 2.1-89.6). Among all adolescents with suicidal ideation, those who also reported psychotic symptoms had a nearly 20-fold increased odds of suicide plans and suicide acts compared with adolescents with suicidal ideation who did not report psychotic symptoms (OR, 19.6; 95% CI, 1.8-216.1). CONCLUSIONS Psychotic symptoms are strongly associated with increased risk for suicidal behavior in the general adolescent population and in adolescents with (nonpsychotic) psychiatric disorder. In both studies, an absolute majority of adolescents with more severe suicidal behavior (suicidal plans and acts) reported psychotic symptoms when directly questioned about this as part of a psychiatric interview. Assessment of psychotic symptoms should form a key part of suicide risk assessment.
Robot eye-hand coordination learning by watching human demonstrations: a task function approximation approach (2019)

We present a robot eye-hand coordination learning method that can directly learn visual task specification by watching human demonstrations. Task specification is represented as a task function, which is learned using inverse reinforcement learning(IRL [1]) by inferring a reward model from state transitions. The learned reward model is then used as continuous feedbacks in an uncalibrated visual servoing(UVS [2]) controller designed for the execution phase. Our proposed method can directly learn from raw videos, which removes the need for hand-engineered task specification. Benefiting from the use of a traditional UVS controller, the training on real robot only happens at initial Jacobian estimation which takes an average of 4-7 seconds for a new task. Besides, the learned policy is independent from a particular robot, thus has the potential of fast adapting to other robot platforms. Various experiments were designed to show that, for a task with certain DOFs, our method can adapt to task/environment changes in target positions, backgrounds, illuminations, and occlusions.
Breaking Barriers: Racism @ Iowa State (2013)

Let’s take a stride through the stained history of America together. Imagine skipping through your last history textbook—the cover is hard and thick, a little worn on the edges and the thin plastic casing is engraved with scratches and marks from past owners. The books are worn because of the idealism behind learning history—that those who learn history will not repeat it.
Impaired fast-spiking interneuron function in a genetic mouse model of depression (2015)

Rhythmic neuronal activity provides a frame for information coding by co-active cell assemblies. Abnormal brain rhythms are considered as potential pathophysiological mechanisms causing mental disease, but the underlying network defects are largely unknown. We find that mice expressing truncated Disrupted-in-Schizophrenia 1 (Disc1), which mirror a high-prevalence genotype for human psychiatric illness, show depression-related behavior. Theta and low-gamma synchrony in the prelimbic cortex (PrlC) is impaired in Disc1 mice and inversely correlated with the extent of behavioural despair. While weak theta activity is driven by the hippocampus, disturbance of low-gamma oscillations is caused by local defects of parvalbumin (PV)-expressing fast-spiking interneurons (FS-INs). The number of FS-INs is reduced, they receive fewer excitatory inputs, and form fewer release sites on targets. Computational analysis indicates that weak excitatory input and inhibitory output of FS-INs may lead to impaired gamma oscillations. Our data link network defects with a gene mutation underlying depression in humans.
On the Late Plays of Eugene O‘Neill (1958)

Death has not lessened Eugene O’Neill’s dominance over the serious American theatre. He towers over other American dramatists with a gigantism almost equal to that with which his characters tower over ordinary mortals. He died in 1953 at the age of 65, having had only one Broadway production in nineteen years, and none thoroughly successful in twenty years. Yet anyone who would evaluate the American theatre since the second World War is obliged to reckon with Eugene O’Neill, and that hardly at all because of the 1946 production of The Iceman Cometh but rather because of the amazing concentration of his works which began to be produced in 1956. In May of that year, the off-Broadway group at The Circle-in-the-Square gave The Iceman Cometh its first successful performance in New York.

This paper illustrates the concept of ''Mii & You'' workshop which is under the framework of ''The Monumental Data project'' that aims to empower cultural memory via the usage of Information & Communication Technologies and especially with sensor type communication and mobile devices. Such practice has to include a set of aesthetic information covering a person's cultural data. We are using Wii console as an interface and we are working on Wii's Mii Plaza editor in order to formulate cultural identities which are moving perpetually and arbitrarily into an abstract/digital place via wireless systems.
Orlistat, a New Lipase Inhibitor for the Management of Obesity (2000)

Orlistat, a weight-loss agent with a novel mechanism of action, recently was approved by the Food and Drug Administration for the treatment of obesity. It inhibits gastric and pancreatic lipases in the lumen of the gastrointestinal tract to decrease systemic absorption of dietary fat. In several trials lasting up to 2 years, orlistat was more effective than diet alone for weight reduction and maintenance of lost weight. Orlistat treatment also results in modest improvements in total cholesterol, low-density lipoprotein, blood pressure, and fasting glucose and insulin concentrations. The major adverse effects are gastrointestinal, usually occur early in therapy, and tend to decrease with continued treatment. Because orlistat may decrease the absorption of fat-soluble vitamins, a standard multiple-vitamin supplement is recommended daily during therapy to prevent abnormalities in vitamin serum concentrations. The potential for severe gastrointestinal discomfort and the modest degree of weight loss may limit the agent's clinical utility. Its long-term safety and effectiveness for weight maintenance, cost-effectiveness of treatment, and overall reduction in obesity-related morbidity and mortality remain to be determined.
