Axial load-settlement (P-S) curves govern pile serviceability checks and support performance-based foundation decisions, yet full static load tests to high load levels remain expensive and are often unavailable. This paper presents PILE-STACK, a physics-guided, monotone stacked ensemble that predicts the complete P-S r…

Text4baby (T4b), a free nation-wide mobile health information service, delivers health-related text messages (SMS) to pregnant women. The objective of this study was to determine the effectiveness of physical activity (PA) specific SMS to improve PA in pregnant women (vs standard T4b) and the most effective dose/timing…

Supporting data entry by clinicians is considered one of the greatest challenges in implementing electronic health records. In this paper we describe a formative evaluation study using three different methodologies through which we identified obstacles to point-of-care data entry for eye care and then used the formativ…

High Impedance Surfaces (HIS) have recently shown the ability to support leaky waves, and to excite plasmonic and HIS resonance frequency modes for use as an antenna. In this paper, we analyzed, designed, and fabricated a true metasurface antenna (TMA) by directly feeding edge-located HIS cells through a microstrip fee…

Pulmonary artery dissection and aneurysms ruptures are rare events, occasionally reported as a cause of sudden death. We report a 27-year-old man who was admitted to the hospital with history of a loss of consciousness and died soon after resuscitation was performed. On autopsy macroscopic examination, 2500 ml partiall…

OBJECTIVES: Authors evaluate diagnosis, surgery and results in the implantees with malformed inner ear. METHODS: Four children with the inner ear malformations were included in this series (one child with common cavity, two children with narrow internal auditory meatus and one child with lateral semicircular canal apl…

PURPOSE: To assess radiology researchers' perceptions of whether, and to what extent, the political context during the current Trump administration (2025-present) affected their research activities, collaborations, work environment, motivation, mobility, and overall research progress. METHODS: Corresponding authors wh…

CONTEXT: Independent validation of published scientific results through study replication is a pre-condition for accepting the validity of such results. In computation research, full replication is often unrealistic for independent results validation, therefore, study reproduction has been justified as the minimum acce…

Despite the fact that replantation of the thumb is at present a common procedure, occasionally due to the different reasons replantation is unsuccessful. We present a case where we have to cope with complete thenar loss and following reconstruction was done in an unusual way. Primarily we have covered the thenar defect…

Most of medical journals now has it's electronic version, available over public networks. Although there are parallel printed and electronic versions, and one other form need not to be simultaneously published. Electronic version of a journal can be published a few weeks before the printed form and must not has identic…

Individual processive molecular motors, of which conventional kinesin is the most studied quantitatively, move along polar molecular tracks and, by exerting a force F = (F(x),F(y),F(z)) on a tether, drag cellular cargoes, in vivo, or spherical beads, in vitro, taking up to hundreds of nanometre-scale steps. From observ…

The aim of our study was to optimise current therapy of gastric tumours. The studied population consisted of 92 patients treated at the 1st Department of Surgery, St. Anne's Teaching Hospital, Brno, Czech Republic, and at the Department of Radiation Oncology of the same hospital during 1994-2000. We have proven that, n…

Sequence specific cleavage of RNA can be achieved by hammerhead ribozymes as well as DNAzymes. They comprise a catalytic core sequence flanked by regions that form double strands with complementary RNA. While different types of ribozymes have been discovered in natural organisms, DNAzymes derive from in vitro selection…

This article brings the biomechanical analysis of sport--Nordic walking--for patients with osteoporotic fractured vertebrae and shows that it is suitable for them. Based on the biomechanical model of skeletal load we have developed a method of walking movement for patients, different from the method of walking movement…

OBJECTIVES: To determine advantages and specific problems of film-free digital hospital focused on radiology department. BACKGROUND: In the St. Elisabeth Oncology Institute in Bratislava we have more than 6-year experience with digital modalities and the PACS system. During this period many difficulties occurred and a…

The authors have gained their experience in psychostereotactic operations during the past 50 years. The operations were indicated in psychiatric patients on the basis of their clinical pictures. The results gained in operations of the hypothalamus, limbic system and neocortical structures of the brain were logically an…

The availability of Internet-enabled computers in the operating room (OR) facilitates unparalleled physician access to current peer reviewed research, either in abstract or full text format, a development that provides physicians with an exciting opportunity to incorporate such findings into clinical practice at the po…

BACKGROUND: Google Scholar linked more visitors to biomedical journal Web sites than did PubMed after the database's initial release; however, its usefulness in locating primary literature articles is unknown. OBJECTIVE: To assess in both databases the availability of primary literature target articles; total number o…

The aim of the present study was to define more accurately the necessary health care in patients with the primary Sjogren's syndrome and to compare it to those necessary for patients with another autoimmune disease--rheumatoid arthritis without a concomitant Sjogren's syndrome (Tab. 1, Ref. 5).
