Kathryn P. Lowry, Laura Ichikawa, Rebecca A. Hubbard, Diana S. M. Buist, more

Cancer > 129 > 8 > 1173 - 1182

Background In women with previously treated breast cancer, occurrence and timing of second breast cancers have implications for surveillance. The authors examined the timing of second breast cancers by primary cancer estrogen receptor (ER) status in the Breast Cancer Surveillance Consortium. Methods Women who were diagnosed with American Joint Commission on Cancer stage I–III breast cancer were...

A. Halicki, M. Specht, A. Stateczny, C. Specht, more

TransNav : International Journal on Marine Navigation and Safety of Sea... > 2023 > Vol. 17 No. 2 > 445--453

This article explores the use of Light Detection And Ranging (LiDAR) derived point clouds to extract the shoreline of the Lake Kłodno (Poland), based on their geometry properties. The data collection was performed using the Velodyne VLP-16 laser scanner, which was mounted on the HydroDron Unmanned Surface Vehicle (USV). A modified version of the shoreline extraction method proposed by Xu et al. was...

There are many manufacturers on the market offering various types of Unmanned Aerial Vehicles (UAV). The multitude of drones available on the market means that the choice of a UAV for a specific application appears to be a decision problem to be solved. The aim of this article is a comparative analysis of drones used in photogrammetric surveys. The criteria for evaluating the UAVs were: availability...

Impact of hydrotechnical structures on forming the tombolo oceanographic phenomenon in Kołobrzeg and Sopot

C. Specht, O. Lewicka, M. Specht, S. Zblewski

TransNav : International Journal on Marine Navigation and Safety of Sea... > 2021 > Vol. 15 No. 3 > 687--694

The process of global sea level rise is causing several significant changes in the coastal zone. Sea level rise and the frequency, strength and duration of storms are also occurring on the Polish coast. As a result, coastal protection measures, such as man-made engineering structure, are necessary. These engineering structures affect (among others) the marine ecosystem in different ways. Although...

Local Editing of Procedural Models

M. Lipp, M. Specht, C. Lau, P. Wonka, more

Computer Graphics Forum > 38 > 2 > 13 - 25

Procedural modeling is used across many industries for rapid 3D content creation. However, professional procedural tools often lack artistic control, requiring manual edits on baked results, diminishing the advantages of a procedural modeling pipeline. Previous approaches to enable local artistic control require special annotations of the procedural system and manual exploration of potential edit...

Polish Maritime Research > 2019 > 26 > 2

This paper is the fourth in a series of publications presenting the process of installation, testing and long-term assessment of the navigational parameters of the Polish DGPS system. This series of publications intends to present – to the general public – the accomplishments of teams of Polish scientists who have been working for years to make the DGPS the main positioning system used in the Polish...

Polish DGPS System: 1995-2018 – studies of reference station operating zones

C. Specht, M. Specht, P. S. Dąbrowski

TransNav : International Journal on Marine Navigation and Safety of Sea... > 2019 > Vol. 13, no. 3 > 581--586

The operating zone of a radio navigation system is one of its main operating features. It determines the size of a water body in which the system can be used, while guaranteeing vessels’ navigation safety. The DGPS system in the LF/MF range is now the basic positioning system in coastal waters around the world, which guarantees not only metre positioning accuracy, but it is also the only one to provide...

Use of a least squares with conditional equations method in positioning a tramway track in the Gdansk agglomeration

K. Czaplewski, C. Specht, P. Dąbrowski, M. Specht, more

TransNav : International Journal on Marine Navigation and Safety of Sea... > 2019 > Vol. 13. no. 4 > 895--900

Satellite measurement techniques have been used for many years in different types of human activity, including work related to staking out and making use of rail infrastructure. First and foremost, satellite techniques are applied to determine the tramway track course and to analyse the changes of its position during its operation. This paper proposes using the least squares with conditional equations...

Banding age ratios reveal prairie waterfowl fecundity is affected by climate, density dependence and predator–prey dynamics

Hannah M. Specht, Todd W. Arnold, Silke Bauer

Journal of Applied Ecology > 55 > 6 > 2854 - 2864

Fecundity estimates for demographic modelling are difficult to acquire at the regional spatial scales that correspond to climate shifts, land use impacts or habitat management programmes. Yet they are important for evaluating such effects. While waterfowl managers have historically used harvest‐based age ratios to assess fecundity at continental scales, widely available age ratios from late summer...

Phase I/II Trial of Combined Pegylated Liposomal Doxorubicin and Cyclophosphamide in Metastatic Breast Cancer

Amy E. Chang, Qian V. Wu, Isaac C. Jenkins, Jennifer M. Specht, more

Clinical Breast Cancer > 2018 > 18 > 1 > e143-e149

Doxorubicin in combination with cyclophosphamide is active in breast cancer; however, its use in metastatic cancer is limited owing to cardiotoxicity. Pegylated liposomal doxorubicin (PLD) was formulated to decrease the toxicity of conventional doxorubicin. We evaluated the safety and efficacy of PLD with metronomic oral cyclophosphamide.We conducted a single-arm open-label phase I/II study of PLD...

Availability of the GNSS geodetic networks position during the hydrographic surveys in the ports

C. Specht, A. Makar, M. Specht

TransNav : International Journal on Marine Navigation and Safety of Sea... > 2018 > Vol. 12, no. 4 > 657--661

Geodetic network GNSS receivers are more commonly associated with positioning systems used in maritime hydrography. In terms of positioning accuracy when no terrain obstacles are present, they meet international hydrographic surveys standards (S‐44) fully. Those standards are defined as 1m (0.95) for Exclusive Order and 2m (0.95) for Special Order. It is equally as important to ensure access to position...

Application of an autonomous/unmanned survey vessel (ASV/USV) in bathymetric measurements

C. Specht, E. Switalski, M. Specht

Polish Maritime Research > 2017 > 24 > 3

The accuracy of bathymetric maps, especially in the coastal zone, is very important from the point of view of safety of navigation and transport. Due to the continuous change in shape of the seabed, these maps are fast becoming outdated for precise navigation. Therefore, it is necessary to perform periodical bathymetric measurements to keep them updated on a current basis. At present, none of the...

Fracture fixation in the operative management of hip fractures (FAITH): an international, multicentre, randomised controlled trial

Aaron Nauth, Aaron T. Creek, Abby Zellar, Abdel-Rahman Lawendy, more

The Lancet > 2017 > 389 > 10078 > 1519-1527

Reoperation rates are high after surgery for hip fractures. We investigated the effect of a sliding hip screw versus cancellous screws on the risk of reoperation and other key outcomes. For this international, multicentre, allocation concealed randomised controlled trial, we enrolled patients aged 50 years or older with a low-energy hip fracture requiring fracture fixation from 81 clinical centres...

Presentation Trainer: what experts and computers can tell about your nonverbal communication

J. Schneider, D. Börner, P. Rosmalen, M. Specht

Journal of Computer Assisted Learning > 33 > 2 > 164 - 177

The ability to present effectively is essential for professionals; therefore, oral communication courses have become part of the curricula for higher education studies. However, speaking in public is still a challenge for many graduates. To tackle this problem, driven by the recent advances in computer vision techniques and prosody analysis, multimodal tools have been designed to support the development...
