Experimental study of the shear strength of a snow-mortar interface
No full textWithin the wide field of snow mechanics the shear strength of snow is paramount. In the scientific literature a wide number of experimental and theoretical works exist with reference to the progressive shear failure of snow-snow interfaces under different conditions of internal and external actions. On the contrary, to our knowledge, few studies are devoted to the shear behaviour at the contact between a snow layer and a solid stiff material, although this topic could have various fields of application (e.g., glide avalanches, snow removal, snow-structure interaction, etc.). Here, we analyze results of experimental direct shear tests carried out in displacement control on a snow-mortar interface at given conditions of temperature and sintering times. We additionally use the Mohr-Coulomb failure criterion to represent shear strength along the interface both in failure and post-failure conditions
Essays on market microstructure
No full textThe first essay analyzes the market microstructure of the European Climate Exchange (ECX), the largest European Union Emissions Trading Scheme trading venue. Spreads range from 2 to 6 times the minimum tick increment on European Union Allowances (EUA) futures. Market impact estimates imply that an average trade will move the EUA market by 1.08 euro centimes. Information shares imply that approximately 90% of price discovery is taking place in the ECX futures market. We find imbalances in the order book help predict returns for up to three days. A simple trading strategy that enters the market long or short when the order imbalance is strong is profitable even after accounting for spreads and market impact. The second essay provides a case that the Thompson-Waller (TW) estimator would have downward bias, which has not been carefully discussed in the literature. Such case is that (i) the buy (sell) order tends to follow buy (sell) order and (ii) the price changes associated to such orders are small. The upward bias of the TW estimator would be canceled out by the downward bias, and in such case the estimator would perform better than the other absolute price change methods. The application to the EUA futures contract trading implies that its trading pattern and the price change provide the conditions that reduce the bias of the TW estimator. The Madhavan, Richardson and Roomans model is applied to examine the spread component of the market. A dominance of asymmetric information component in the spread is found. The fraction of the spread attributable to that component increases gradually during the observation period. The final essay examines price discovery of Japanese companies' Tokyo-New York cross-listed shares. Kalman filter is utilized to estimate partial price adjustment model. By employing Kalman filter, the present research can deal with missing values problem researchers has to confront in order to analyze non-overlapping markets such as Tokyo and New York. I find that events with larger magnitude of efficient price change occur during Tokyo opening hours. Dynamic measure shows that New York Stock Exchange is more efficient in price discovery.Ph.

Espace et Révolution : enquête, grande peur et fédérations
No full textThis study proposes an initial approach to the metamorphosis of the consciousness of space as it was experienced during the Revolution. First it analyzes the structure of the space in which villagers lived on the eve of the Revolution by the computer data processing of the answers to an inquiry made in the Dauphiné en 1789 concerning contacts and connections of all sorts (markets, food supplies, doctors and mid-wives). The author then examines the ways in which space as experienced was disrupted and analyzes the structure of the communication networks disclosed through La Grande Peur. Finally Yoichi Uriu studies the efforts made to reestablish the disrupted space relations through an analysis of the Federations movement, and the turning point they represented in the formation of a national space.Cette recherche propose une première approche de la métamorphose de la conscience de l'espace vécu à travers la Révolution. Elle s'attache d'abord à une étude de la structure de l'espace dans lequel vivaient les villageois à la veille de la Révolution en analysant grâce à un traitement informatique les réponses données à une enquête menée en Dauphiné en 1789 sur les contacts et relations de tous genres (marchés, subsistances, médecins et sages-femmes). On examine ensuite comment cet espace vécu a été bouleversé, et quelle est la structure des réseaux de communications qui se sont révélés dans la Grande Peur. Enfin, on étudie quels efforts ont été faits pour reconstruire cet espace bouleversé en analysant le mouvement des Fédérations et le tournant qu'ils représentent dans la constitution d'un espace national.Uriu Yoichi.

Assessing the current utilization status of wearable devices in clinical research
No full textBackground/Aims Information regarding the use of wearable devices in clinical research, including disease areas, intervention techniques, trends in device types, and sample size targets, remains elusive. Therefore, we conducted a comprehensive review of clinical research trends related to wristband wearable devices in research planning and examined their applications in clinical investigations. Methods As this study identified trends in the adoption of wearable devices during the planning phase of clinical research, including specific disease areas and targeted number of intervention cases, we searched ClinicalTrials.gov—a prominent platform for registering and disseminating clinical research. Since wrist-worn devices represent a large share of the market, we focused on wrist-worn devices and selected the most representative models among them. The main analysis focused on major wearable devices to facilitate data analysis and interpretation, but other wearables were also surveyed for reference. We searched ClinicalTrials.gov with the keywords “ActiGraph,”“Apple Watch,”“Empatica,”“Fitbit,”“Garmin,” and “wearable devices” to obtain studies published up to 21 August 2022. This initial search yielded 3214 studies. After excluding duplicate National Clinical Trial studies (the overlap was permissible among different device types except for wearable devices), our analysis focused on 2930 studies, including simple, time-series, and type-specific assessments of various variables. Results Overall, an increasing number of clinical studies have incorporated wearable devices since 2012. While ActiGraph and Fitbit initially dominated this landscape, the use of other devices has steadily increased, constituting approximately 10% of the total after 2015. Observational studies outnumbered intervention studies, with behavioral and device-based interventions being particularly prevalent. Regarding disease types, cancer and cardiovascular diseases accounted for approximately 20% of the total. Notably, 114 studies adopted multiple devices simultaneously within the context of their clinical investigations. Conclusions Our findings revealed that the utilization of wearable devices for data collection and behavioral interventions in various disease areas has been increasing over time since 2012. The increase in the number of studies over the past 3 years has been particularly significant, suggesting that this trend will continue to accelerate in the future. Devices and their evaluation methods that have undergone thorough validation, confirmed their accuracy, and adhered to established legal regulations will likely assume a pivotal role in evaluations, allowing for remote clinical trials. Moreover, behavioral intervention therapy utilizing apps is becoming more extensive, and we expect to see more examples that will lead to their approval as programmed medical devices in the future
