Authors: Rodriguez-Arias H. A. , Mendoza-González A. 
Published: June 2020

Abstract
The following project presents an autonomous system of classification of objects by colors which it is applied to the caps of plastic bottles, emulating an automated work cell, which serves to students to know the operation of industrial processes, from construction, programming and even maintenance point of view. The entire project consists of the design of a conveyor system which has a sensor to identify colors, and actuators which allow the caps are correctly classified in the containers according to its color. The work cell was built in a modular way in such a way that in the future it can be adapted to other work cells and simulate flexible manufacturing cells, since it can be reprogrammed not only to identify by colors but also by sizes. Besides, the pieces were built using the 3D printer and the laser cutter in order to use the tools of the laboratories of our institution in the construction of elements for future laboratory equipment which will strengthen the electromechanical program.

Published: June 2020

Abstract
In the present document, the Cepstrum transform and the analysis of principal components were used to differentiate amplitudes in the mechanical vibrations produced by unbalance and misalignment with respect to a reference group. This document requires three stages. It begins with levelling in order to establish the control group. The unbalancing was carried out with a known mass located in the two radial distances of the first and second flywheels. The misalignment was made by running the sliding supports back 0.5, 1.0 and 1.5 degrees. In the second stage, Matlab algorithms were created for both cepsctrum and main component analysis. In the last stage the obtained data were analyzed identifying the differences that may exist in the analyzed records. The project focused on the use of Matlab to find differences at a frequency of 30 Hz. The results obtained made it possible to determine that it is possible to find differences with the proposed methodology.

Abstract
A correlational statistical analysis was carried out in two university institutions of Cartagena of India’s, which allowed us to infer whether the educational entities envision the curricula of the Law program, the inquiry as a daily activity of students and professors and if they have socio-legal research center, with lines of research that place the development of investigative processes, with identity of managerial criteria, since it is the entity that designs and arranges the curriculum of this training program so that the lawyer who graduates, orients his daily legal practice in the investigative with the support of ICT. Surveys were applied to teachers of the law program, which allowed us to determine the strength of association or correlation between variables A and B through a population sample, to make inference to the formation of a lawyer, as well as a humanist, whose discipline be the socio-legal research so that, being a lawyer, you can devote yourself to observe, collect, select, describe, classify and analyse the elements that are in a social environment or space to frame it in the legal system with the support of legal computer systems. It was obtained as a result that (ICT) have evolved in a very fast way the daily life of teachers in the surveyed universities, since young teachers are not traumatized by the use of new technologies because they are daily familiar with computers, the internet and its communication tools, while teachers at the end of the century are considered digital illiterates.
Predicting excited states from ground state wavefunction by supervised quantum machine learning
Authors: Kawai Hiroki , Nakagawa Yuya O. 
Published: June 2020

Abstract
Excited states of molecules lie in the heart of photochemistry and chemical reactions. The recent development in quantum computational chemistry leads to inventions of a variety of algorithms that calculate the excited states of molecules on near-term quantum computers, but they require more computational burdens than the algorithms for calculating the ground states. In this study, we propose a scheme of supervised quantum machine learning which predicts the excited-state properties of molecules only from their ground state wavefunction resulting in reducing the computational cost for calculating the excited states. Our model is comprised of a quantum reservoir and a classical machine learning unit which processes the measurement results of single-qubit Pauli operators with the output state from the reservoir. The quantum reservoir effectively transforms the single-qubit operators into complicated multi-qubit ones which contain essential information of the system, so that the classical machine learning unit may decode them appropriately. The number of runs for quantum computers is saved by training only the classical machine learning unit, and the whole model requires modest resources of quantum hardware that may be implemented in current experiments. We illustrate the predictive ability of our model by numerical simulations for small molecules with and without noise inevitable in near-term quantum computers. The results show that our scheme reproduces well the first and second excitation energies as well as the transition dipole moment between the ground states and excited states only from the ground states as inputs. We expect our contribution will enhance the applications of quantum computers in the study of quantum chemistry and quantum materials.

Abstract
Despite an historical connection between the arts and sciences, in the past century, the two disciplines have been greatly siloed. However, there is a renewed interest in collaboration across the arts and sciences to support conservation practice by understanding and communicating complex environmental, social, and cultural challenges in novel ways. 6&6 was created as a transdisciplinary art–science initiative to promote a deeper appreciation of the Sonoran Desert. Six artists and six scientists were paired to create work that explored conservation issues in the Sonoran Desert and the Gulf of California. In-depth interviews were conducted with the artists and scientists throughout the 4-year initiative to understand the impact of 6&6 on their personal and professional behaviors and outlook. The findings from this case study reveal the role that intensive, place-based, and transdisciplinary art–science programs can play in shaping narratives to better communicate the patterns and processes of nature and human–environment interactions.

AbstractChronic obstructive pulmonary disease (COPD) is a significant risk factor for lung cancer. One potential mechanism through which COPD contributes to lung cancer development could be through generation of an immunosuppressive microenvironment that allows tumor formation and progression. In this study, we compared the status of immune cells and immune checkpoint proteins in lung tumors induced by the tobacco smoke carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) or NNK + lipopolysaccharide (LPS), a model for COPD-associated lung tumors. Compared with NNK-induced lung tumors, NNK+LPS-induced lung tumors exhibited an immunosuppressive microenvironment characterized by higher relative abundances of PD-1+ tumor-associated macrophages, PD-L1+ tumor cells, PD-1+ CD4 and CD8 T lymphocytes and FOXP3+ CD4 and CD8 T lymphocytes. Also, these markers were more abundant in the tumor tissue than in the surrounding ‘normal’ lung tissue of NNK+LPS-induced lung tumors. PD-L1 expression in lung tumors was associated with IFNγ/STAT1/STAT3 signaling axis. In cell line models, PD-L1 expression was found to be significantly enhanced in phorbol-12-myristate 13-acetate activated THP-1 human monocytes (macrophages) treated with LPS or incubated in conditioned media (CM) generated by non-small cell lung cancer (NSCLC) cells. Similarly, when NSCLC cells were incubated in CM generated by activated THP-1 cells, PD-L1 expression was upregulated in EGFR- and ERK-dependent manner. Overall, our observations indicate that COPD-like chronic inflammation creates a favorable immunosuppressive microenvironment for tumor development and COPD-associated lung tumors might show a better response to immune checkpoint therapies.

Published: June 2020

Abstract

Background
Although Staphylococcus aureus is a leading cause of postsurgical infections, national estimates of these infections after elective surgeries based on microbiology data are limited. This study assessed cumulative 180-day postsurgical S. aureus incidence in real-world hospital settings.

Methods
A retrospective study of adults (≥18 years) undergoing inpatient or hospital-based outpatient elective surgeries from 1/7/2010–30/6/2015 at hospitals (N = 181) reporting microbiology results in the Premier Healthcare Database (PHD). 86 surgical categories were identified from the National Healthcare Safety Network procedures. We classified positive S. aureus cultures using a hierarchy (bloodstream [BSI], surgical site [SSI], and all other types [urinary tract, respiratory, other/unknown site]) and calculated incidence (number of infections divided by the number of elective surgery discharges). We estimated national infection case volumes by multiplying incidence by national inpatient elective surgical discharge estimates using the entire PHD and weights based on hospital characteristics.

Results
Following 884 803 inpatient elective surgical discharges, 180-day S. aureus infection incidence was 1.35% (0.30% BSI, 0.74% SSI no BSI, 0.32% all other types only). Among 1 116 994 hospital-based outpatient elective surgical discharges, 180-day S. aureus incidence was 1.19% (0.25% BSI, 0.75% SSI no BSI, 0.19% all other types only). Methicillin resistance was observed in ~45% of the S. aureus infections. We estimated 55 764 S. aureus postsurgical infections occurred annually in the US following 4.2 million elective inpatient surgical discharges.

Conclusions
The high burden of S. aureus infections after both inpatient and outpatient elective surgeries highlights the continued need for surveillance and novel infection prevention efforts.

Authors: Yehya Nadir , Venkataramani Atheendar , Harhay Michael O 
Published: June 2020

Abstract

Background
Social distancing is encouraged to mitigate viral spreading during outbreaks. However, the association between distancing and patient-centered outcomes in coronavirus disease 2019 (COVID-19) has not been demonstrated. In the United States, social distancing orders are implemented at the state level with variable timing of onset. Emergency declarations and school closures were 2 early statewide interventions.

Methods
To determine whether later distancing interventions were associated with higher mortality, we performed a state-level analysis in 55 146 COVID-19 nonsurvivors. We tested the association between timing of emergency declarations and school closures with 28-day mortality using multivariable negative binomial regression. Day 1 for each state was set to when they recorded ≥ 10 deaths. We performed sensitivity analyses to test model assumptions.

Results
At time of analysis, 37 of 50 states had ≥ 10 deaths and 28 follow-up days. Both later emergency declaration (adjusted mortality rate ratio [aMRR] 1.05 per day delay; 95% confidence interval [CI], 1.00–1.09; P = .040) and later school closure (aMRR 1.05; 95% CI, 1.01–1.09; P = .008) were associated with more deaths. When assessing all 50 states and setting day 1 to the day a state recorded its first death, delays in declaring an emergency (aMRR 1.05; 95% CI, 1.01–1.09; P = .020) or closing schools (aMRR 1.06; 95% CI, 1.03–1.09; P &lt; .001) were associated with more deaths. Results were unchanged when excluding New York and New Jersey.

Conclusions
Later statewide emergency declarations and school closure were associated with higher Covid-19 mortality. Each day of delay increased mortality risk 5 to 6%.
Microhabitat Variation in Egg Diapause Incidence in Summer Within a Local Population: An Adaptation to Decline in Host-Plant Suitability in Trigonotylus caelestialium (Hemiptera: Miridae)
Authors: Shintani Yoshinori , Nagamine Keisuke 
Published: June 2020

Abstract
Diapause induction in multivoltine insects is an ecophysiological event that is generally triggered by seasonal cues such as photoperiod and temperature. The rice leaf bug, Trigonotylus caelestialium (Kirkaldy), feeds on various Poaceae grasses and produces several generations a year. Previous studies have shown that adults produce diapause and nondiapause eggs under short-day and long-day conditions, respectively. However, there is a distinct mid-summer peak in diapause incidence before an autumnal increase in diapause incidence in the field, which cannot be explained by the laboratory results. The present study was performed to examine the environmental factors affecting the diapause incidence in mid-summer and the adaptive significance of this phenomenon. Seasonal trends in diapause incidence differed significantly among three sites located 150–400 m apart from each other and with different host plants. The suitability of host plants differs depending on species and seasonally. Therefore, the microhabitat difference in diapause trend is believed to be due to the difference in host plants. When field-collected female adults laying diapause eggs in late June were fed a seasonally deteriorating host (the orange foxtail, Alopecurus aequalis Sobol. [Poales: Poaceae]), they kept laying diapause eggs, whereas when fed a suitable host (the wheat, Triticum aestivum L. [Poales: Poaceae]) for 5 d, they changed oviposition mode to lay nondiapause eggs. These results indicate that host-plant suitability affects the oviposition mode of T. caelestialium. Diapause-egg oviposition in mid-summer in T. caelestialium has adaptive significance as a bet-hedging strategy against unpredictable dietary conditions.

Abstract
Glycerolized Nile tilapia skin (NTS) showed promising results when used for burn treatment in phases II and III randomized controlled trials. This pilot study aims to evaluate the effectiveness of lyophilized NTS (LNTS) as a temporary skin substitute for superficial partial-thickness burns by comparing it with silver-impregnated sodium carboxymethylcellulose dressing. This was a randomized, prospective, open-label, and controlled pilot study conducted in Fortaleza, Brazil, from April 2019 to December 2019. The 24 participants had ≥18 and ≤70 years of age and superficial partial-thickness burns affecting up to 10% of TBSA. Primary outcomes were the number of dressings performed and pain intensity, assessed via the Visual Analogue Scale and the Electronic von Frey. Secondary outcomes were the level of pain-related anxiety, assessed via the Burns Specific Pain Anxiety Scale, and analgesic consumption. In the test group, the number of dressings and the patient-reported pain after dressing-related procedures were lower. Analgesic intake, pain-related anxiety, and both patient-reported and objectively measured pain before dressing-related procedures were similar for the treatment groups. No adverse effects were detected. LNTS shares the same characteristics of an “‘ideal’” wound dressing demonstrated by glycerolized NTS in previous studies. Also, it demonstrated noninferiority for burn management when compared with silver-impregnated sodium carboxymethylcellulose dressing. The safety and efficacy of LNTS demonstrated in this pilot study may allow the development of larger phases II and III RCTs in a near future.
A Novel Head Capsule Labial Gland Lobe in the Black Field Cricket (Orthoptera: Gryllidae)
Authors: Pereira Monique Campos , Cooper Paul D 
Published: June 2020

AbstractWe describe a pair of labial gland lobes on either side of the retrocerebral complex in the head of the Australian black field cricket, Teleogryllus commodus Walker. As the retrocerebral complex includes the corpora cardiaca and corpora allata, hormones secreted by these glands can be absorbed by these lobes. These lobes of the labial gland are connected to the thoracic lobes via a relatively long duct that enters the main duct draining the thoracic lobes. Measurement of the flow rate of dye from head to thorax in the ducts is rapid, suggesting that these glands may serve as a transport system into the thoracic region. Both serotonin and adipokinetic hormone are shown to be present in the lobes near the retrocerebral complex and the ducts of the thoracic lobes, but whether this connection between the head and thorax acts as a hormone transporter is still unclear.
It’s...Complicated: A Theoretical Model of Music-Induced Harm
Authors: Silverman Michael J , Gooding Lori F , Yinger Olivia 
Published: June 2020

AbstractWhile literature exists supporting the use of music for health promotion, scholars have also noted the potential for music-induced harm and other maladaptive effects of music. Harm is a multifaceted construct that can include affective, behavioral, cognitive, identity, interpersonal, physical, and spiritual aspects. As music also represents a multifaceted experience, the relationship between music and harm is complex and can include numerous contextual-, deliverer-, music-, and recipient-based factors. Music-induced harm (MIH) also needs to be clearly defined to understand and protect against it. Therefore, the purpose of this article was to explore the numerous factors influencing how music can result in harm and develop a theoretical model that could be used to inform safe music practices. Drawing from existing models of emotional responses to music, music intervention reporting guidelines, therapeutic functions of music, and holistic wellness, we explored how the interplay between the deliverer, music, and recipient can result in various types of MIH in diverse contexts. We then developed the MIH model to integrate these factors and connect the model with the existing literature. The MIH model highlights the relevance of academic and clinical training, credentialing, occupational regulation, continuing education, and professional organizations that provide accredited curricular oversight to protect people from MIH. Implications for clinical application, limitations, and suggestions for future research are provided.

Published: June 2020

Abstract
An 8-year-old girl was admitted with four limb weakness for 2 months. Hyperactive reflexes were observed in all four limbs, and positive Hoffmann’s signs were revealed. An MRI spine with the coronal slide detected two tumors, first in the intradural and intramedullary space at the C2–C4 level and the second in the intradural and extramedullary space at the C5–C7 level. Axial T1W contrast MRI brain showed a tumor in the left parietal region. The patient underwent spine surgery first and following by brain surgery. No invasive lesions were remarked during surgery. Histological findings showed meningothelial meningioma and ependymoma from the spine and rhabdoid meningioma from the brain. Two months after the second surgery, the patient recovered fully with no symptoms and was able to participate in all regular activities in life. This work is the first report of a mixed tumor with distinct spinal meningioma and ependymoma components occurring in the cervical spinal cord at the C2–C7 level and coexisting with cranial meningioma. The remarkable result was that the patient fully recovered without any symptoms after receiving two surgeries.
