A Recommender for the Management of Chronic Pain in Patients Undergoing Spinal Cord Stimulation

Spina1 cord stimulation (SCS) is a therapeutic approach used for the management of chronic pain. It involves the delivery of electrical impulses to the spinal cord via an implanted device, which when given suitable stimulus parameters can mask or block pain signals. Selection of optimal stimulation parameters usually happens in the clinic under the care of a provider whereas at-home SCS optimization is managed by the patient. In this paper, we propose a recommender system for the management of pain in chronic pain patients undergoing SCS. In particular, we use a contextual multi-armed bandit (CMAB) approach to develop a system that recommends SCS settings to patients with the aim of improving their condition. These recommendations, sent directly to patients though a digital health ecosystem, combined with a patient monitoring system closes the therapeutic loop around a chronic pain patient over their entire patient journey. We evaluated the system in a cohort of SCS-implanted ENVISION study subjects (Clinicaltrials.gov ID: NCT03240588) using a combination of quality of life metrics and Patient States (PS), a novel measure of holistic outcomes. SCS recommendations provided statistically significant improvement in clinical outcomes (pain and/or QoL) in 85% of all subjects (N=21). Among subjects in moderate PS (N=7) prior to receiving recommendations, 100% showed statistically significant improvements and 5/7 had improved PS dwell time. This analysis suggests SCS patients may benefit from SCS recommendations, resulting in additional clinical improvement on top of benefits already received from SCS therapy.
An Extremely Low-profile Dual-band Antenna Based on Miniaturized Metasurface for 5G Mobile Applications

In this paper, we propose a dual-band metasurface (MTS)-based antenna with an extremely low-profile for 5G mobile applications. The MTS is miniaturized and suitable to be placed on the back cover of the mobile phone. Compared with the conventional patch-based MTS, the area of the proposed one has decreased by 61.7%. With an extremely low-profile of 0.008 $\lambda_{0} (>\lambda_{0}$ is the vacuum wavelength at 3.5 GHz), the proposed antenna can partially cover two 5G bands of N78 (7.9%, 3.37-3.65 GHz) and N79 (5.3%, 4.77-5.03 GHz) The lower band is produced by the feeding-slot on the ground layer, while the upper band is mainly generated by MTS. The MTS-based antenna is also suitable to be expanded into a 4 × 4 MIMO system without additional space. The simulated results show that the isolations among the ports are all above 20 dB in the two operating bands.
An xAI Approach for Data-to-Text Processing with ASP

The generation of natural language text from data series gained renewed interest among AI research goals. Not surprisingly, the few proposals in the state of the art are based on training some system, in order to produce a text that describes and that is coherent to the data provided as input. Main challenges of such approaches are the proper identification of"what"to say (the key descriptive elements to be addressed in the data) and"how"to say: the correspondence and accuracy between data and text, the presence of contradictions/redundancy in the text, the control of the amount of synthesis. This paper presents a framework that is compliant with xAI requirements. In particular we model ASP/Python programs that enable an explicit control of accuracy errors and amount of synthesis, with proven optimal solutions. The text description is hierarchically organized, in a top-down structure where text is enriched with further details, according to logic rules. The generation of natural language descriptions' structure is also managed by logic rules.
Cognitive Load Study Using Increasingly Immersive Levels of Map-based Information Portrayal on the End User Device

Abstract : This study was an investigation of the effect of the four different types of maps (2-D north up [2D-NU] map; 2-D rotating [2D-R], course up map; third-person perspective [3PP] map; and an augmented reality [AR] display) on map-based task performance and cognitive load. Thirty-one Soldiers from the Officer Candidate School (OCS) at Fort Benning, GA, and one Staff Sergeant participated in the study. Each Soldier completed four scenarios; one with each of the four different types of maps. Performance was evaluated based on objective performance data, data collector observations, and Soldier questionnaires. Although the 2D-NU map was preferred by the most Soldiers, generally their performance and self-reported cognitive workload ratings with the 2D-R and the 3PP maps were not significantly worse than with the 2D-NU. All four maps types offered certain advantages, depending on the situation and terrain and should be further examined in a live experiment. It is possible that all four map types should be included on an end user device (EUD) so that Soldiers can choose the map based upon the situation and their preferences or so that they can move between maps when the situation warrants.
Scoping Conceptions of Equity: Reviewing a Decade of Physical Activity Research

Lee and Cubbin’s (2009) call for a “socially just” Ecological Model of Physical Activity (EMPA) prompted an inquiry into physical activity (PA), active living (AL) research that advances social justice framed as a set of equity-centered principles for research. In response to the call, we conducted a scoping review to explore how PAAL research has operationalized equity to advance a socially-just EMPA. We searched for original research, published between 2010 and 2020, using key terms for ‘physical activity’ and ‘equity’ that produced 5,152 non-duplicated records. Title-abstract screening for exclusion/inclusion criteria disqualified 4,392 records. A review protocol and coding guide was developed, piloted, and revised by team members. The remaining 760 abstracts were reviewed and consensus coded for PA Variable (dependent or independent) and Factor (individual outcome or contextual exposure), Equity (population demographic or social-environmental determinant), and Social Ecological Milieu (SEM) (PAAL-specific or SEM-general policy, system, or environment (PSE) operations. Of the 463 studies selected, PA codified as an individual outcome (67%) more often than as a contextual-exposure (33%) factor. Equity codified more frequently as a population demographic (69%) rather than as a social-environmental determinant (31%). The SEM codified as PAAL-specific (44%) or as SEM-general (56%) PSE factors. Based on multistep study abstract reviews, the selected studies more often missed the opportunity to center equity in PAAL research by examining social, environmental, political, and systemic factors as institutionalized inequities at the root of PAAL disparities. We will not achieve a socially-just EMPA without shared conceptualizations of equity followed by intentional action.
Circularly Arranged Six Element Cavity Backed SIW Arc Shape Slot Antenna

In this research work, cavity backed antenna (CBA) with arc shape slot and circularly arranged six element cavity backed arc shape slot antenna are proposed by incorporating Substrate Integrated Waveguide (SIW) technology. Initially, a single element CBA having arc shaped slot in opposite layer to feedline, is considered. The cavity boundaries are constructed with the technique used under SIW technology. The antenna offered high gain and low cross polarization (X-Pol) behavior in operating frequency bands. The designed cavity backed SIW arc shape antenna offers twin operational band in the operating frequency range of 10.12 GHz to 10.34 GHz (1st band) and 13.58 GHz to 13.96 GHz (2nd band). The found mid operating frequencies are 10.21 GHz, and 13.79 GHz, while at mid operating frequencies achieved antenna gain is 12.01 dBi and 12.50 dBi, respectively in the direction of intended communication. Furthermore, six elements circularly arranged assembly is created such that arc slots are oriented along the transversal direction along with longitudinal orientation to feedline (tapered microstrip line). The design of circularly arranged six element CBA achieves a greater bandwidth, enhanced gain and overall reduced amount of cross polarization value. The designed array of the cavity backed SIW are shape slot antenna also offers twin band outcome in the operating radio frequency (RF) band of 10.26 GHz to 10.61 GHz (1st band) and 13.71 GHz to 14.16 GHz (2nd band), and the achieved mid operating frequencies are 10.41 GHz and 13.96 GHz, respectively. At these frequencies antenna gain is 20.10 dBi and 20.50 dBi, in the direction of communication. The proposed model has achieved an overall antenna efficiency of 93%.
Same-Day Discharge vs Inpatient Robotic-Assisted Radical Prostatectomy: Complications, Time-Driven Activity-Based Costing, and Patient Satisfaction

Purpose: Historically, robotic-assisted radical prostatectomy is accompanied by an inpatient hospital admission. The COVID-19 pandemic necessitated a transition to same-day discharge robotic-assisted radical prostatectomy in some centers to free up critically needed inpatient beds. This study aims to compare complications, total health care costs, and patient satisfaction for same-day discharge vs inpatient robotic-assisted radical prostatectomy. Materials and Methods: We compared 392 consecutive robotic-assisted radical prostatectomies performed as same-day discharge (n = 206) vs inpatient (n = 186) from February 2020 to November 2022 at 2 academic medical centers. We utilized propensity score analysis to assess the impact of same-day discharge vs inpatient robotic-assisted radical prostatectomy on 30-day complications (primary outcome). Time-driven activity-based costing analysis was applied to compare total costs of robotic-assisted radical prostatectomy care, and we administered a validated Patient Satisfaction Outcome Questionnaire to compare satisfaction scores. Results: Inpatient robotic-assisted radical prostatectomy patients were more likely to be older, self-reported Black race or Hispanic ethnicity, and have higher American Society of Anesthesiologists classification. Complication rates were nonsignificantly lower for same-day discharge vs inpatient robotic-assisted radical prostatectomy (OR 0.87, 95% CI 0.35 to 2.21; P = .8). Same-day discharge vs inpatient robotic-assisted radical prostatectomy demonstrated a $2106 (19%) overall cost reduction. Median satisfaction survey scores were similar, and a clinically significant difference can be excluded. Conclusions: Same-day discharge robotic-assisted radical prostatectomy is cost-effective and should be the preferred approach in appropriately selected patients.
Alternatives for the Valorization of Avocado Waste Generated in the Different Links of the Value Chain Based on a Life-Cycle Analysis Approach

This work evaluates the sustainability of small-scale biorefineries as a potential enterprise alternative to be introduced in rural areas based on experimental and simulation data. Four scenarios were evaluated: the first scenario involves the production of guacamole, the second involves the production of animal feed, and the third and fourth scenarios involve the extraction of bioactive compounds and the production of avocado oil or animal feed, respectively. In addition, all scenarios produce biogas and fertilizer. Each of the scenarios were evaluated considering the technical, economic, environmental, and social aspects. As a main result, the first scenario showed the lowest operating and investment costs, as well as the lowest economic profitability (profit margin 35%). On the other hand, the third and fourth scenarios present the highest investment and operating expenses (OpEx USD 6.2 million per year and CapEx USD 1.0 million), but their profit margins are in the 60–70% range. Furthermore, a life-cycle assessment (LCA) was carried out and allows inferring that the transformer link presents the highest environmental impact of the entire value chain and that the carbon footprint for all scenarios ranges between 1.01–2.41 kg CO2 eq per kg avocado. Similarly, the social impact methodology shows that the proposed scenarios do not present any social risk. Thus, the biorefinery for animal feed, bioactive compounds, biogas, and fertilizer was selected as the best option to be implemented in Caldas.
Dynamique océanique et transport de la matière particulaire dans le Golfe du Lion : crue, tempête et période hivernale

Des observations in situ et la modelisation ont ete conjointement utilisees pour mieux comprendre les processus physiques qui controlent les echanges cote-large et etudier les transferts de matiere particulaire gouvernes par l'effet des courants et des vagues dans le Golfe du Lion. Cette etude montre que les tempetes de vent marin induisent une circulation cyclonique sur le plateau et un processus de downwelling dans les canyons sous-marins. En periode automnale, lorsque la colonne d'eau est stratifiee et que l'eau du plateau est legere, le downwelling est limite en profondeur. En revanche, en hiver, les plongees d'eaux denses, formees lors des vents de nord froids sur le plateau, intensifient ce processus. D'autre part, les tempetes de vent marin sont responsables de fortes remises en suspension sur l'ensemble du plateau (> 5 M t) et d'une exportation massive dans la partie ouest du Golfe. Le canyon du Cap Creus apparait comme une voie d'exportation privilegiee vers le large.

Preventing co-infection: a viral strategy with short-term benefits and long-term drawbacks

Viral co-infection occurs when multiple distinct viral particles infect the same host. This can impact viral evolution through intracellular interactions, complementation, reassortment and recombination. In nature many viral species are found to have a wide range of mechanisms to prevent co-infection, which raises the question of how viral evolution is impacted by this strategic choice. Here, we address this question in a model viral system, the ubiquitous bacteriophage and its host bacteria. Using a stochastic model of phage-host interactions in agent-based simulations, we first characterise the behaviour of neutral mutants and find that co-infection decreases the strength of genetic drift. We then quantify how variations in the phage life history parameters affect viral fitness. Importantly, we find that the growth rate (dis)advantage associated with variations in life history parameters can be dramatically different from the competitive (dis)advantage measured in direct-competition simulations. Additionally, we find that co-infection facilitates the fixation of beneficial mutations and the removal of deleterious ones, suggesting that selection is more efficient in co-infecting populations. We also observe, however, that in populations which allow co-infection, a mutant that prevents it displays a substantial competitive advantage over the rest of the population, and will eventually fix even if it displays a much lower growth rate in isolation. Our findings suggest that while preventing co-infection can have a negative impact on the long-term evolution of a viral population, in the short-term it is ultimately a winning strategy, possibly explaining the prevalence of phage capable of preventing co-infection in nature.
Plant Hormone and Fatty Acid Screening of Nicotiana tabacum and Lilium longiflorum Stigma Exudates

Pollen germination in vivo on wet stigmas is assisted by the receptive fluid—stigma exudate. Its exact composition is still unknown because only some components have been studied. For the first time, hormonal screening was carried out, and the fatty acid (FA) composition of lipid-rich (Nicotiana tabacum) and sugar-rich (Lilium longiflorum) exudates was studied. Screening of exudate for the presence of plant hormones using HPLC-MS revealed abscisic acid (ABA) in tobacco stigma exudate at the two stages of development, at pre-maturity and in mature stigmas awaiting pollination, increasing at the fertile stage. To assess physiological significance of ABA on stigma, we tested the effect of this hormone in vitro. ABA concentration found in the exudate strongly stimulated the germination of tobacco pollen, a lower concentration had a weaker effect, increasing the concentration did not increase the effect. GC-MS analysis showed that both types of exudate are characterized by a predominance of saturated FAs. The lipids of tobacco stigma exudate contain significantly more myristic, oleic, and linoleic acids, resulting in a higher unsaturation index relative to lily stigma exudate lipids. The latter, in turn, contain more 14-hexadecenoic and arachidic acids. Both exudates were found to contain significant amounts of squalene. The possible involvement of saturated FAs, ABA, and squalene in various exudate functions, as well as their potential relationship on the stigma, is discussed.

Photocatalytic and Photothermal Antimicrobial Mussel-Inspired Nanocomposites for Biomedical Applications

Bacterial infection has traditionally been treated with antibiotics, but their overuse is leading to the development of antibiotic resistance. This may be mitigated by alternative approaches to prevent or treat bacterial infections without utilization of antibiotics. Among the alternatives is the use of photo-responsive antimicrobial nanoparticles and/or nanocomposites, which present unique properties activated by light. In this study, we explored the combined use of titanium oxide and polydopamine to create nanoparticles with photocatalytic and photothermal antibacterial properties triggered by visible or near-infrared light. Furthermore, as a proof-of-concept, these photo-responsive nanoparticles were combined with mussel-inspired catechol-modified hyaluronic acid hydrogels to form novel light-driven antibacterial nanocomposites. The materials were challenged with models of Gram-negative and Gram-positive bacteria. For visible light, the average percentage killed (PK) was 94.6 for E. coli and 92.3 for S. aureus. For near-infrared light, PK for E. coli reported 52.8 and 99.2 for S. aureus. These results confirm the exciting potential of these nanocomposites to prevent the development of antibiotic resistance and also to open the door for further studies to optimize their composition in order to increase their bactericidal efficacy for biomedical applications.
