Behind the Book Publishing Miracle of Taiwan: An Analysis of Book-distribution Systems and Commerce Circuits of Publishing in Taiwan

While Taiwan’s book market is not a big one, but the number of new books published annually is rather startling. According to the statistics from International Publishers Association, there are 42,118 new book titles published in 2013, which means 1,831 new titles for every million people, just less than the 2,875 new titles figure for the UK in the same year. This research is intended to analyze the “book publishing miracle” and book distribution systems in Taiwan, and to explore the rationale operated in these circulation systems. I will argue that, due to the distinct historical and social context, Taiwan’s book publishing industry developed a distinguished model, which I call “compressed growth”, and this model leads to a “path dependency” of the growth pattern of this industry. Besides that, the over-production strategies and habits of publishers, and some peculiar institutions of the book distribution system, such as return privilege, checkout and payment system between the suppliers and booksellers, all of them have reinforced the publishers’ old tactics of “publishing to raise cash for the next book” (以書養書), and contributed to the high volumes of new books of our book market. In addition to the production conventions of the publishers, the inefficient midstream distributors and the powerful chain bookstore also contributed to the oversupply of the book market. All of these constituted a vicious circle of this industry, and cheapen the value of the
TECHNOLOGY OF PRODUCING, STRUCTURE AND OPTICAL PROPERTIES OF TiO2 AND Ag-TiO2 THIN FILMS OBTAINED BY ION-PLASMA SPUTTERING

Thin TiO2 films and Ag-TiO2 film nanocomposites were obtained by ion-plasma sputtering of a titanium target and a combined titanium and silver target in argon. Raman spectroscopy showed that as-grown TiO2 films have the anatase structure. Subsequent annealing at of 500 С transforms anatase structure of the TiO2 films into rutile one. Ag-TiO2 films structure differs from TiO2 ones and during annealing also tends to the rutile structure. As-grown TiO2 films are characterized by high transparency in the visible region of the spectrum, which is weakly dependent on annealing. Optical transparency of Ag-TiO2 film nanocomposites is much less than that in TiO2 films and increases significantly during annealing, which may be due to the atomization of silver nanoparticles and their subsequent diffusion beyond the film.
COUETTE FLOW IN A PARTIALLY POROUS CURVED CHANNEL WHICH IS SLIGHTLY ECCENTRIC

This paper presents analytical solutions of the flow and temperature distributions in a configuration similar to the polar Couette flow except that a porous layer is inserted on top of the lower curved surface and the upper sliding surface is allowed to slightly displace. The solution is obtained through the use of the perturbation method with the eccentricity ratio being the perturbation parameter that is no greater than 0.1. With the end effects close to both ends of the curved surface being neglected, a slight displacement of the upper sliding surface either compresses or decompressed the flow. With the presence of the porous layer, the velocity profile is further compressed within the fluid layer leading to a greater shear stress experienced on the upper sliding surface. If viscous dissipation is more important than the heat conduction in the fluid, the relative motion of fluid particles close to the sliding surface heats up the fluid.
Eager to Take Part in the Global AI Race? Better, Look for Traps Waiting There for You

—The concept of Artificial Intelligence (AI) was introduced about 60 years ago. At the same time, Artificial Neural Networks (ANNs) were devised as a means for AI implementation. They were conceived as a collection of small interconnected computational units (called artificial neurons), which are supposed to imitate the biological neurons of the human brain. Essentially, ANNs were devised as data processing units – 60 years ago, all things in the world were considered computational. But today, the brain is thought as an information processing system. Therefore, biological neurons (and their artificial analogs) should be considered as information-processing units. This shift in the underlying assumptions is overlooked by almost all AI designers. I think it will be nice to find someone, who will be ready to share with me my understanding of these new and challenging issues.

Stroke is one of the most disabling diseases that mankind has experienced. The disability caused after stroke can be effectively reduced when the patient is encouraged to undergo regular rehabilitation therapy. This paper studies the use of quantitative electroencephalogram (QEEG) feedback to motivate the patient during his rehabilitation phase by providing progressive information on neurological recovery. Two different parameters are considered: 1. The alpha asymmetry of hemispheric stroke patients 2. The relative mean alpha band power and the delta alpha band power ratio (DAR). QEEG can serve as a non-invasive, low cost alternative that can be used to measure the brain activity as the recovery progresses. It is not intended to replace the current gold standard of brain activity measurement (e.g. fMRI). The therapists can also use these parameters to design or modify therapy for specific patients. This paper explores the real-time monitoring of these parameters.
Algal Content Of Freshwater Sponges: A Comparison Of The Two Sponge Types From Two Lakes In Western Montana

Earlier studies have indicated particle selection as a means of controlling interspecific competition between freshwater sponges. Thus, an attempt was made to observe differences in two sponge types, Ephydatia muelleri and a possible ecotype, from two different lakes, Salmon Lake and Coopers Lake, in the same drainage system. The results support particle selection but the means of selection remains unclear. A comparison of the algae found in the two lakes is also made showing significant differences.
IS THERE ECONOMIC CONVERGENCE IN THE EU?

One of the main objectives of the European Union is the economic convergence between member countries. In the following paper we examine how this objective has been met in the case of two of the most recent expansions of the union (in 2004 and 2007) for the periods 2001-2006 and 2001-2012. The model developed in this paper aims to find evidence for convergence, as well as determine some important causing factors of it. Furthermore, we look at the different speeds of convergence between the more recent and the older EU members. Our empirical work shows that convergence is present in the European Union in both periods discussed in the paper and has been faster in the group of new member states in the period 2001-2006. Moreover, we have concluded that migration turnover is significant factor fostering convergence, while the effect of corruption is ambiguous.
R A ] 7 N ov 2 01 9 QUIVER MUTATIONS AND BOOLEAN REFLECTION MONOIDS

In 2010, Everitt and Fountain introduced the concept of reflection monoids. The Boolean reflection monoids form a family of reflection monoids (symmetric inverse semigroups are Boolean reflection monoids of type A). In this paper, we give a family of presentations of Boolean reflection monoids and show how these presentations are compatible with quiver mutations of orientations of Dynkin diagrams with frozen vertices. Our results recover the presentations of Boolean reflection monoids given by Everitt and Fountain and the presentations of symmetric inverse semigroups given by Popova respectively. Surprisingly, inner by diagram automorphisms of irreducible Weyl groups and Boolean reflection monoids can be constructed by sequences of mutations preserving the same underlying diagrams. Besides, we show that semigroup algebras of Boolean reflection monoids are cellular algebras.
Space Debris Identification and Characterization via Deep Meta-Learning

We describe a new class of deep learning algorithms that can discriminate debris from non-debris objects using light curve real and simulated data. Recently our team demonstrated that deep neural networks (e.g. Convolutional Neural Networks or CNN), trained on real and simulated light curves can be effectively employed in discriminating between active satellites, debris and rocket bodies. However, such algorithms are computationally expensive to train and require a large number of available labeled data. The latter are generally time consuming to obtain. Recently, a new paradigm within the machine learning community emerged, where deep networks are designed with procedures that can teach the system to “learn-tolearn. ” Named Meta-Learning, it relies on the assumption that a deep learning system can mimic the ability of humans to efficiently learn to recognize objects from a few examples. Indeed, metalearning is implemented by defining a learning procedure that can be carried along a distribution of the multiple tasks, each with a limited number of examples. Here, we train deep networks with meta-learning (e.g. Model-Agnostic MetaLearning, MAML) to show that such class of algorithms can effectively solve the debris/non-debris problem by processing light curves. Preliminary results show that meta-learning framework can efficiently and quickly learn to discriminate debris from nondebris object under a variety of observational conditions.
Outbreaks of Aflatoxicoses in India

Mycotoxins particularly aflatoxins are gaining increasing importance due to their deleterious effects on human and animal health and also due to ubiquitous presence of aflatoxigenic fungi in all the agricultural commodities under field and storage conditions. In general, aflatoxins occur more frequently in tropical countries because of high temperature, moisture, unseasonal rains and flash floods. Poor harvesting practices, improper storage and less than optimal conditions during transport and marketing can also contribute to mycotoxin production. Chronic health risks are particularly prevalent in India where the diets of people are highly prone to aflatoxigenic fungi and aflatoxins. The present paper reviews the disease outbreaks of aflatoxicoses in India due to the ingestion of contaminated food and feed with aflatoxins. One of the first outbreaks of aflatoxicosis was reported from western India during 1974 with 106 deaths of indigenous people whose staple food was maize. This is perhaps the first report directly incriminating aflatoxin in food as a human health hazard at the indigenous community level. An independent study of the same outbreak was carried out subsequently also indicated that the aflatoxins were the major cause of the outbreak. Indian childhood cirrhosis, a clinical condition mainly confined to the Indian subcontinent has been attributed to aflatoxin contamination. They also found a correlation between aflatoxin contamination and fungal load on the one hand and hepatomegaly in children on the other in south Canara district of Karnataka. Another outbreak of toxic hepatitis affecting both humans and dogs was reported in India during 1974. Heavy mortality in chicks in Chittoor district of Andhra Pradesh was reported in 1982 due to aflatoxicosis. Another outbreak of aflatoxicosis in commercial poultry farms was also reported in the same district with hundred percent mortality. A case of aflatoxicosis in Murrah buffaloes from Andhra Pradesh was also reported. Occurrence of aflatoxicosis in poultry in Mysore state was first recognized in 1966 where 2219 chicks died in one week. Subsequently, several sporadic incidences were found in various poultry farms in Karnataka. Most of the outbreaks of aflatoxicoses described here are a consequence of ingestion of food that is contaminated with aflatoxins. Disease outbreaks due to aflatoxins continue to be problems of significant public health concern in India as long as people will consume contaminated food. The strict control of food quality is therefore necessary to avoid such incidences.
N ov 2 01 9 NONLOCAL CAHN-HILLIARD-BRINKMAN SYSTEM WITH REGULAR POTENTIAL : REGULARITY AND OPTIMAL CONTROL

In this paper we study optimal control problem for non local Cahn-HilliardBrinkman system which models phase separation of binary fluids in porous media. We consider the system in two dimensional bounded domain with regular potential. We extend recently proved existence of weak solution results for such a system and prove the existence of strong solution under certain assumptions on the forcing term and initial datum. Further using our regularity results, we study the tracking type optimal control problem. We prove the existence of an optimal control and establish the first order optimality condition. Lastly, we characterize optimal control in terms of the solution of corresponding adjoint system. The existence of solution for the adjoint system is also established.
Uniqueness of solutions of linear relay systems1

Conditions are given for uniqueness of solutions of linear time-invariant systems under relay feedback. From a hybrid dynamical point of view this entails the deterministic specification of the discrete transition rules. The results are based on the formulation of relay systems as complementarity systems, and use the constructive theory of the Linear Complementarity Problem. ( 1999 Elsevier Science Ltd.

Social Media Collaboration in Software Project Management

Social media has become part and parcel of the world of today. These days, it’s still the most talked about thing. It cannot be overlooked because it plays a key role in our business functions such as marketing and advertising. Social Media is all about collaboration on files, ideas and projects that help users and stakeholders to successfully complete the project. It influences how people communicate, develop relationship, build trust, increase transparency and provide cultural context. The fundamental aim of this research is to investigate the capacity for project management in social media. This paper explains how social media is used for project management knowledge areas and process groups. Also this research aims to identify SM tools that can be suitable for project management processes. Two studies Delphi Study of three rounds and structured case study interview are used to investigate the impact on the performance of the project team and process robustness. These studies support social media use by accessing the contribution to relationship building, trusts, coordination and cohesion.
Comparison of the Usability of the ReWalk, Ekso and HAL Exoskeletons in a Clinical Setting

Since the 1970s, research has been conducted to design exoskeletons to help paraplegics overcome limited mobility. Three different devices (ReWalk*, Ekso**, and HAL***) were tested in the following study. Two of these systems (Ekso and HAL) have been an integral part of the treatment of paraplegic patients at our centre Bergmannstrost in Halle (Saale) since April 2014. The Ekso is used to treat complete and incomplete paraplegic patients; with a device called Variable Assist it is possible to use remaining muscle function when paraplegia is incomplete. The HAL is used for therapy of paraplegic patients with a Janda strength level of at least 3/5 for hip flexion and knee extension. The results show that while exoskeletons can be used as therapy aids to supplement existing options, they are not an alternative to a wheelchair and should not be prescribed as orthopaedic devices. The systems require further optimisation to make them safe enough to be used as orthopaedic devices.
Cerebrovascular and systemic haemodynamic parameters during passive exercise

Abstract Passive range of motion exercises (PROM) are often used in immobilized patients but are scarcely investigated. The aim of this study was therefore to investigate the safety of PROM with respect to intracranial, cerebrovascular and systemic haemodynamic parameters in critically ill patients at a neurosurgical intensive care unit (NICU). Twelve consecutively enrolled NICU patients underwent monitoring of their intracranial (ICP) and systemic blood pressures (BP), heart rate, cerebral blood flow velocities (CBFV) and pulsatility index (PI) during PROM treatment. Cerebral perfusion pressure (CPP) was calculated. For comparison, 12 healthy age- and gender-matched controls underwent similar testing except for ICP and CPP assessments. Patients had a lower ICP after PROM (p=0.006) but unaffected BP. Control subjects had lower BP during and after PROM (p=0.01). CBFV data and PI remained unchanged during PROM in both patients and controls, but with a significantly higher PI in the patient group than the controls. PROM can safely be used in critically ill NICU patients.
PREVENTING VISION LOSS FROM AGE-RELATED MACULAR DEGENERATION: OPPORTUNITIES AND INVESTIGATIONS *

Nutritional supplementation as demonstrated in the Age-Related Eye Disease Study has helped to delay the progression of age-related macular degeneration (AMD), but it is not curative. Therefore, prevention of advanced AMD (choroidal neovascularization or geographic atrophy) is desirable for avoiding or minimizing the central vision loss that may progress to blindness in patients with AMD. Epidemiological investigations have identified certain risk factors for AMD, including some that are modifiable. These findings suggest certain behaviors that may help to delay disease progression. This article reviews epidemiological findings and summarizes continuing clinical investigations of the role of antioxidants and laser treatment in preventing disease progression.

Analyzing 100 Billion Measurements: A NILM Architecture for Production Environments

An architecture for Non-Intrusive Load Monitoring is presented along with a software implementation in the Java language. Various characteristics of the architecture that make it suitable for production deployments are discussed. In particular, a streamlined interface allows load monitoring algorithms to be developed by third parties without full source code access, supports both online and offline appliance recognition, integrates with an adaptive scheduler, and is agnostic with respect to the recognition approach. The Java implementation has been fieldtested in a commercial, customer-facing application where it continues to manage NILM operations on more than 100 billion individual energy measurements.
The Challenges of Cell Transplantation and Genetic Engineering for the Treatment of Diabetes

I n the past decade there has been a great deal of enthusiasm and high expectations for cell transplantation and genetic engineering. Many excellent laboratories have studied experimental protocols but unfortunately most have unveiled substantial difficulties. With the exception of bone marrow transplantation and blood transfusion cell transplants have been disappointing but the early good results of pancreatic islet transplants led to increased activity to turn this into acceptable therapy. In the meantime gene therapy has for the most part been disappointing. It is difficult to get appropriate expression for prolonged periods of the gene in question and the use of viral vectors has exposed certain important dangers. In this review I have discussed these matters and also pointed towards more encouraging avenues that are recently being pursued.

Methodological Perspectives on Second Language Prosody

In the first part, the paper offers a review of models, hypotheses and methods found in the literature on the perception of L2 phonemes and of L1 intonation categories. The goal of the review is to point out which methods and hypotheses can be useful for investigating the perception of intonation in L2 and if they need to be adapted for such purpose. In the second part of the paper, a brief summary is offered of an experiment to check if Italian-L1 subjects detect functional differences in English-L2 in the case such differences are conveyed by pitch accents phonetically, but not functionally, similar to L1 pitch accents. The description of main aspects concerning experimental design and results aims to show that: 1) integrating methods and usual practices found in the literature on perception of L2 phonemes and L1 intonation gives interesting results in the investigation of L2 intonation (as shown by reaction time measurements), although, in some cases, methodological adjustments are needed (e.g., splitting oddity discrimination tests); 2) results are consistent with the predictions of degrees of difficulties in discrimination that depend on the phonetic (and functional) features of L1 and L2 intonational patterns, similarly to what proposed by Best’s PAM model for phonemes.
Role of a Food Box Program: In Fruit and Vegetable Consumption and Food Security

Purpose: We examined whether participation in a food box program has a positive effect on fruit and vegetable consumption and food security. Methods: Participants and nonparticipants in a food box program were surveyed to determine differences between the two groups and change over time. Results: Fruit and vegetable intake declined in those who left the program after several months, and intake of fruit, carrots, and vegetables was lower among those who had left than among those who remained in the program. Food insecurity was associated with lower intakes of fruit and vegetables. Conclusions: Participation in a food box program can provide some benefit in terms of increased fruit and vegetable consumption for those who use the program regularly. Increasing the frequency of the box and encouraging continued use may improve these effects.
