Enabling technology for human collaboration. (2003)

This report summarizes the results of a five-month LDRD late start project which explored the potential of enabling technology to improve the performance of small groups. The purpose was to investigate and develop new methods to assist groups working in high consequence, high stress, ambiguous and time critical situations, especially those for which it is impractical to adequately train or prepare. A testbed was constructed for exploratory analysis of a small group engaged in tasks with high cognitive and communication performance requirements. The system consisted of five computer stations, four with special devices equipped to collect physiologic, somatic, audio and video data. Test subjects were recruited and engaged in a cooperative video game. Each team member was provided with a sensor array for physiologic and somatic data collection while playing the video game. We explored the potential for real-time signal analysis to provide information that enables emergent and desirable group behavior and improved task performance. The data collected in this study included audio, video, game scores, physiological, somatic, keystroke, and mouse movement data. The use of self-organizing maps (SOMs) was explored to search for emergent trends in the physiological data as it correlated with the video, audio and game scores. This exploration resulted in the development of two approaches for analysis, to be used concurrently, an individual SOM and a group SOM. The individual SOM was trained using the unique data of each person, and was used to monitor the effectiveness and stress level of each member of the group. The group SOM was trained using the data of the entire group, and was used to monitor the group effectiveness and dynamics. Results suggested that both types of SOMs were required to adequately track evolutions and shifts in group effectiveness. Four subjects were used in the data collection and development of these tools. This report documents a proof of concept study, and its observations are preliminary. Its main purpose is to demonstrate the potential for the tools developed here to improve the effectiveness of groups, and to suggest possible hypotheses for future exploration.
The impact of nutrient density in terms of energy and/or protein on live performance, metabolism and carcass composition of female and male broiler chickens of two commercial broiler strains (2009)

The objective of this study was to investigate the effects of diet composition on performance, slaughter yield and plasma metabolites, as different modern broiler strains show different responses to feed intake. Broilers of two commercial strains and of both sexes received one of three diets being different in energy and/or protein level [control diet, low energy/low protein diet (LM/LP) and low protein diet (LP)]. Low energy/low protein diet chickens were characterized by significantly lower body weights and feed intake compared with their LP and control counterparts. Broilers of the Cobb strain or broilers that were fed the control diet were most efficient in converting energy to body weight. No significant differences in plasma metabolites were detected due to diet composition or genotype. The diet with the lower energy and crude protein levels reached the lowest slaughter yield but the highest drumstick and wing percentages. The lowest mortality percentages were observed for broilers fed the LM/LP diet, and Cobb birds appeared to be more sensitive for metabolic disorders resulting in death. It is obvious from this study that different genotypes respond differently to changes in diet composition and therefore have adjusted nutritional requirements.
Failure-aware Runtime Verification of Distributed Systems (2015)

Prior runtime-verification approaches for distributed systems are limited as they do not account for network failures and they assume that system messages are received in the order they are sent. To overcome these limitations, we present an online algorithm for verifying observed system behavior at runtime with respect to specifications written in the real-time logic MTL that efficiently handles out-of-order message deliveries and operates in the presence of failures. Our algorithm uses a three-valued semantics for MTL, where the third truth value models knowledge gaps, and it resolves knowledge gaps as it propagates Boolean values through the formula structure. We establish the algorithm's soundness and provide completeness guarantees. We also show that it supports distributed system monitoring, where multiple monitors cooperate and exchange their observations and conclusions.
Excitation of EMIC waves detected by the Van Allen Probes on 28 April 2013 (2014)

Abstract We report the wave observations, associated plasma measurements, and linear theory testing of electromagnetic ion cyclotron (EMIC) wave events observed by the Van Allen Probes on 28 April 2013. The wave events are detected in their generation regions as three individual events in two consecutive orbits of Van Allen Probe‐A, while the other spacecraft, B, does not detect any significant EMIC wave activity during this period. Three overlapping H + populations are observed around the plasmapause when the waves are excited. The difference between the observational EMIC wave growth parameter ( Σ h ) and the theoretical EMIC instability parameter ( S h ) is significantly raised, on average, to 0.10 ± 0.01, 0.15 ± 0.02, and 0.07 ± 0.02 during the three wave events, respectively. On Van Allen Probe‐B, this difference never exceeds 0. Compared to linear theory ( Σ h &gt; S h ), the waves are only excited for elevated thresholds.
Electrical properties, texture, and microstructure of vicinal YBa2Cu3O7−δ thin films (2002)

Vicinal YBa2Cu3O7−δ (YBCO) thin films of thickness h=20–480 nm are grown by pulsed-laser deposition on 10° miscut (001) SrTiO3 substrates. The anisotropic resistivities, c-axis texture, and critical temperature drastically depend on the thickness of vicinal films. High-resolution electron microscopy reveals a defect microstructure with strong bending of the YBCO lattice near the SrTiO3 interface and improved film microstructure at larger distances to the substrate. The required layer thickness for microstructure relaxation and increase of electrical conductivity are significantly larger than the critical thickness of c-axis oriented YBCO films.
Measuring the semantic relatedness between words and images (2011)

The nurse manager's vocation of leadership derives from both the vocation of being a practicing nurse and the vocation for being a leader, positively impacting and productively contributing to the improvement of the work environment. Consequently, nurse managers with vocation for leadership should be the gold standard role in any healthcare organization. This study was retrospectively registered with the (registros-OSF-bmyvz-v1) on the (26 July 2023) registration number (10.17605/OSF.IO/BMYVZ).
Prostheses and Exoskeletons: Moving From a Mechatronics Bottleneck through a Controls Bottleneck (2016)

The human body is an amazing design that is in many ways superior to anthropometric robots, whether throwing a ball This contrast becomes clear when the person becomes injured and we attempt to augment it with a robotic interface such as a prosthetic limb or a powered exoskeleton to regain mobility. Existing robotic augmentation systems tend to be heavy and have significant inertias due to high transmission ratios But equally important, anthropometric robots tend to have difficulty rendering accurate forces (again due to their high gear ratios) or achieve stable gait in the presence of environmental perturbations, and these control challenges are amplified when the robot must coordinate activities with the user. This is a complex problem that requires an accurate understanding of interaction between the mechatronic system, the control platform, and the human.
Temperature measurement of high-density winding coils of electromagnets (2012)

In this study, the temperature of high-density winding coils of electromagnets is measured without using any temperature measurement probe. In fact, the probe cannot get access to the interior of the coil. Infrared radiometry can measure only the coil surface temperature which can be very different from the interior temperature. In the present measurement technique, the copper winding wire itself is used as the temperature-sensitive element. The current against voltage (I–V) of the coil is first measured. The electrical resistance of the coil is then obtained and plotted against dissipation power. Using the thermal coefficient of the electrical conductivity of copper at ambient temperature (20°C), the coil temperature is deduced and plotted against dissipation power. The resulting temperature is the temperature along the wire averaged over the entire wire length. This is the average interior temperature rather than surface temperature. The case temperature is measured by a precision thermometer. The difference between coil temperature and case temperature is calculated and divided by dissipation power to attain the thermal resistance from the coil to the case. For the electromagnet studied, the thermal resistance is 1.1°C/W. Electromagnets are components that are used in numerous electrical machines and electronic products. Coil temperature measurement is of critical importance because the insulating coating of the winding wire has finite temperature ratings beyond which the coating may deteriorate and get damaged. By using the pulsed mode, the technique presented here can be implemented to measure the coil temperature even while the electromagnets are in operating conditions. It should be valuable to the electricity and motor industries.
Folding free‐energy landscape of a 10‐residue mini‐protein, chignolin (2006)

Chignolin is an artificial mini-protein composed of 10 residues (GYDPETGTWG) that has been shown to cooperatively fold into a beta-hairpin structure in water. We extensively explored the conformational space of chignolin using a 180-ns multicanonical molecular dynamics (MD) simulation and analyzed its folding free-energy landscape. In the MD trajectory, we found structures that satisfy 99% of the experimental restraints and are quite close to the experimentally determined structures with C(alpha) root-mean-square-deviations of less than 0.5 Angstroms. These structures formed a large cluster in the conformational space with the largest probability of existence, agreeing well with the experiment.
Folia Medica Cracoviensia (2021)

Mucormycosis is an invasive fungal disease caused by saprophytic molds and is characterized by a fulminant course and high mortality. Reported increase of disease cases and more frequent mucormycosis superinfections in COVID-19 patients are of a serious concern. Head and neck area is the most typical location of mucormycosis and often the first symptoms are eminent in oral cavity, therefore a dentist may be the first healthcare practitioner to recognize signs of this dangerous and potentially fatal disease. Urgent diagnosis and implementation of appropriate treatment are essential for the patient's survival. The dentist's participation in postoperative care is necessary and due to the destructive nature of radical surgical treatment, prosthetic rehabilitation is required to improve the patient's function and quality of life. Furthermore the vigilance of dentists will also allow early recognition of frequent recurrences of this insidious infection.
Abstract 1612: Bitter melon juice induces apoptotic death of human pancreatic carcinoma cells (2012)

Abstract Pancreatic cancer is one of the deadliest cancers. The prognosis of this malignancy is extremely poor in general and especially at advanced stages of the disease, suggesting that newer preventive/intervention strategies are necessary to improve the outcome of this malignancy. Plant based therapies are often used as alternative and complementary treatments for various diseases including cancer. Bitter melon (Momordica Charantia) is a fruit from the perennially growing climber of Cucurbitacae family. It is a commonly consumed vegetable and is also used as a traditional medicine for treating disease conditions such as diabetes, ulcers, microbial and viral infections, etc. In recent years, the interest in its anti-cancer potential has grown considerably in the scientific community; however, literature still lacks detailed studies on this aspect. In the present study, we assessed the efficacy and associated mechanisms of bitter melon juice (BMJ) against pancreatic cancer. For this, we selected two human pancreatic cancer cell lines, BxPC-3 and MiaPaCa-2, which differ in K-ras status; a major genetic alteration in most pancreatic cancer cases. We observed that treatment of these cells with BMJ (2-4% v/v) significantly decreases the viability by 59-94% and 40-91% after 48h in case of BxPC-3 and MiaPaCa-2 cells, respectively. Decrease in cell viability was largely due to apoptosis induction as evidenced by cell death ELISA and western blot analysis for cleaved caspases-9 and -3. A significant increase in the release of cytochrome-c in the cytoplasmic fraction was also observed, thereby indicating that BMJ activates the intrinsic pathway of apoptosis in these cell lines. Additionally, BMJ significantly increased the levels of pro-apoptotic protein Bak and decreased the levels of anti-apoptotic protein Bcl-XL in both the cell lines. In other studies, BMJ treatment down-regulated XIAP and survivin, but increased p21 and Chop, and caused an activation of ERK and p38 in both cell lines without any effect on JNK. Furthermore, BMJ treatment resulted in significant up regulation in AMPK activation thereby suggesting it might be impinging on additional pathways. In tumor xenograft study, administration of lyophilized BMJ powder in diet (1.5%, w/w) to athymic nude mice for 42 days caused a significant inhibition in MiaPaca-2 xenograft growth in terms of a decrease in tumor volume by 43% (P&amp;lt;0.05) and tumor weight by 52% (P&amp;lt;0.05) without affecting body weight and food intake. Taken together, our findings demonstrate the anti-cancer efficacy of BMJ towards the human pancreatic carcinoma cells irrespective of their genetic background, suggesting that more studies are needed to establish the translational potential of BMJ in human pancreatic cancer control.

Follow a Human using a Mobile Robot Regardless of the Walking Speed (2018)

The humanity is ready to merge intelligent robots into their habitual circumstances to work together, share feelings, and make self-reliant compliance. The capability to follow a human autonomously is essential for a mobile robot to interact with humans. Existing work either requires the human to be in line-of-sight or needs a beacon to be installed, which has great constraints on the human mobility. In this paper, we propose an approach to allow a mobile robot to follow a human regardless of his walking speed. In our setup, a human carries a Tango phone that can perform motion tracking using visual inertial sensing and create a map using its RGB-D sensor. The robot localizes itself in the map by incorporating its on-board Kinect and odometry information. The map quality decreases exponentially with increasing human speed. To produce a map that is suitable for the localization and navigation of the mobile robot, we, therefore, propose a map filter algorithm to improve the map quality. Instead of just following the human path, we propose an algorithm (i.e., trajectory filter) to reduce the cost of path and follow the human simultaneously. Experiments are conducted and the capability is illustrated using ROS on a turletbot platform. We also provide a video link to demonstrate our approach at 202. 94. 70. 33/videos/icarm2018. mp4.
Structural and Secondary Relaxations in Supercooled Di-n-butyl Phthalate and Diisobutyl Phthalate at Elevated Pressure (2004)

Broadband dielectric measurements at very large hydrostatic pressures (up to 1.8 GPa) are used to investigate the effect of molecular structure on the dynamical properties of supercooled di-n-butyl phthalate (DBP) and its isomer, diisobutyl phthalate (DiBP). At atmospheric pressure, both the shape of the α-relaxation loss peak and the fragility are essentially the same for the two materials, although the behavior of their β-relaxations differs. The activation energy for the β-process in DiBP, which is independent of pressure, is larger than that for DBP, while the activation volume of the former is about an order of magnitude larger. In contrast to the similarities of the α-relaxation at low pressure, distinct differences between the two isomers become evident at elevated pressure. The activation volume for the α-relaxation and the pressure coefficient of the glass transition temperature are significantly larger for DBP than DiBP. On the other hand, the fragility of both liquids is invariant to pressure. This latter observation corroborates recent results from high-pressure viscosity measurements on DBP, and is consistent with the invariance of the α-peak breadth to pressure. Related to the large value of the Kohlrausch stretch exponent and its invariance to pressure, there is no decoupling of the α-relaxation times and the dc-conductivity over the investigated range of temperatures and pressures. This is consistent with the idea that the decoupling of dynamic variables upon approach to Tg is a consequence of increases in intermolecular cooperativity and dynamic heterogeneity. We also compare herein the characteristic temperatures, and their associated relaxation times, at which various changes in the dynamics become manifest in the DBP and DiBP.
Progress in plant-based bioelectrochemical systems and their connection with sustainable development goals (2021)

Living organisms' energy conversion is considered as an essential and sustainable green energy source and future bio-hybrid technologies. Recently, plants were used after harvesting as biomass in bio-fermentation as an energy source. In bio-electrochemical systems, microorganisms work with plants to generate electricity, hydrogen, or methane. This work discusses the simultaneous pollutant removal and electricity generation in plant-based bio-electrochemical systems (P-BES). Factors affecting the P-BES performance and the removal efficiencies of the different organic and inorganic pollutants were illustrated. Furthermore, the plant-based bioelectrochemical systems' role in achieving the sustainable development goals (SDGs) was discussed. The SDGs contribution of plant-based bioelectrochemical systems were presented and discussed to evaluate such systems' ability to achieve the three pillars of sustainable development, i.e., economic, environmental, and social.
Effects of bile acids on neurological function and disease (2016)

Bile acids are synthesized from cholesterol and are known to be involved with the emulsification and digestion of dietary lipids and fat-soluble vitamins. Outside of this role, bile acids can act as cell signaling effectors through binding and activating receptors on both the cell membrane and nucleus. Numerous reports have investigated these signaling pathways in conditions where the liver is damaged. More recently, effort has been made to investigate the role of bile acids in diseases outside of those associated with liver damage. This review summarizes recent findings on the influences that bile acids can exert in normal neurological function and their contribution to diseases of the nervous system, with the intent of highlighting the role of these metabolites as potential players in neurological disorders.-McMillin, M., DeMorrow, S. Effects of bile acids on neurological function and disease.
Trace metals intake of Nacella (P) magellanica from the Beagle Channel, Tierra del Fuego (Patagonia, Argentina) (2012)

Nacella species and Mytilus species constitute a popular food in the Beagle Channel zone as both of them are well distributed in the area. With the aim to infer the daily intake of heavy metals through the consumption of these gastropod molluscs in the diet, more than one hundred individuals of Nacella (P) magellanica were sampled, separated in viscera and muscle, and then examined with respect to the accumulation of different transition metals. Collection was performed in seven strategic locations along 170 km of the coastal area of the Beagle Channel (Tierra del Fuego, Argentina) in two campaigns during 2005 and 2007. In this study, the intake of the trace metals Cd, Cr, Cu, Ni, Pb and Zn by molluscs was calculated and evaluated in terms of the potential risks to human health derived from their consumption. Particularly, cadmium and lead presented more interest as they are non–essential and very well known toxic metals. Generally, the integrated evaluation of the results evidence that risks for humans seem unlikely for the regular consumption in the area. Further discussion will be provided on this issue.
Role of Live-coding in Learning Introductory Programming (2018)

Live-coding is an approach to teaching programming by writing actual code during class as part of the lectures. In a live-coding session, the instructor thinks aloud while writing code and the students are able to understand the process of programming by observing the thought processes of the instructor. In our study, we conducted a live-coding session to two groups of students as a part of a teaching intervention that was originally designed for studying the effects of using the native language for learning programming. We analyzed the student feedback data that was collected and found that many students have mentioned about the usefulness of live-coding for learning programming. We conducted a grounded theory analysis of the student feedback data to understand the value of live-coding for learning introductory programming. We found that live-coding (1) makes the process of programming easy to understand for novice programmers, (2) helps students learn the process of debugging, and (3) exposes students to good programming practices. We also found that students prefer to code along with the instructor during a live-coding session rather than being mere observers.
