Authors: Zhou Guangbing , Luo Jing , Xu Shugong , Zhang Shunqing , Meng Shige , Xiang Kui 
Published: May 2021

Purpose
Indoor localization is a key tool for robot navigation in indoor environments. Traditionally, robot navigation depends on one sensor to perform autonomous localization. This paper aims to enhance the navigation performance of mobile robots, a multiple data fusion (MDF) method is proposed for indoor environments.

Design/methodology/approach
Here, multiple sensor data i.e. collected information of inertial measurement unit, odometer and laser radar, are used. Then, an extended Kalman filter (EKF) is used to incorporate these multiple data and the mobile robot can perform autonomous localization according to the proposed EKF-based MDF method in complex indoor environments.

Findings
The proposed method has experimentally been verified in the different indoor environments, i.e. office, passageway and exhibition hall. Experimental results show that the EKF-based MDF method can achieve the best localization performance and robustness in the process of navigation.

Originality/value
Indoor localization precision is mostly related to the collected data from multiple sensors. The proposed method can incorporate these collected data reasonably and can guide the mobile robot to perform autonomous navigation (AN) in indoor environments. Therefore, the output of this paper would be used for AN in complex and unknown indoor environments.
The team leader coaching programme (TLCP) – a programme to implement team coaching in rehabilitation clinics – a feasibility study
Authors: Küllenberg Janna Katharina , Becker Sonja , Körner Mirjam 
Published: May 2021

PurposeTeam coaching is a promising way to advance a shift from the classical leader to a coach who leads his/her interprofessional colleagues. It is acknowledged as an effective instrument to reinforce leaders’ roles but is rarely used in the health-care sector. This paper aims to present the team leader coaching programme (TLCP), designed to strengthen team leaders by implementing coaching tools into their work routine.Design/methodology/approachThe TLCP was designed based on the evaluated intervention on patient-centred team development, an expert workshop and a literature search. It addresses leadership styles, self-reflection, role clarity, attitude, moderation techniques and coaching tools with a focus on systemic questions. It was implemented as a train-the-trainer concept, in two training groups including 27 participants from 12 clinics (“multi-clinic” group) and another in-house training group (“single-clinic” group) including 15 participants from one clinic.FindingsThere were differences in the evaluation of the training between the group that received an inhouse training (“single-clinic” group) and the group that received a workshop in a group of professions from different clinics (“multi-clinic” group) with a tendency for a more positive evaluation by the “multi-clinic” group.Originality/valueThe TLCP is a promising programme to potentially improve teamwork in rehabilitation clinics, as it provides team leaders with coaching tools they can use in their work routine without being dependent on external coaches. It is characterized by a reflective stance, which seems to be highly necessary to optimally fulfil the role of a team leader.
Employee loyalty and counter-productive work behaviour among employees in the Indian hospitality sector
Authors: Rishipal  
Published: May 2021

PurposeThe purpose of this study is to identify the characteristics of employee loyalty and counter-productive work behaviour (CWB) among employees working in the Indian hospitality sector. The study also compared the status of employee loyalty among managers, who exhibit either very high and or very low traits of CWB. The study also examined the factors responsible for the high tendency of employee loyalty and for that of CWB.Design/methodology/approachPrimary data were collected by using questionnaire and interview methods from employees and managers working in hotels situated in the National Capital Region (NCR), Delhi, India. A sample of total 220 junior and middle level managers and other employees was taken and a selected sample was tested for tendencies of employee loyalty and CWB and analyzed to interpret the findings.FindingsThe findings reveal that the tendency of employee loyalty among managers in the hospitality sector was high, whereas the status of CWB was low. Results also predicted that the tendency of employee loyalty was high among the managers with low traits of counter-productive behaviour and very low among managers with a higher tendency of CWB. Factors such as compensation and benefits, job security and growth and satisfaction were found to be responsible for high tendency of employee loyalty; the controlling of factors such as ignoring or arguing with others, physically damaging organizational property, stealing organizational or employee’s property, intentionally working slowly, doing work incorrectly, neglecting to follow procedures, taking longer breaks than allowed, coming late and leaving early was responsible for a high degree of CWB.Research limitations/implicationsThis study was conducted by involving lower and middle level hospitality sector managers in the NCR Delhi region only. To generalize the findings effectively, a more comprehensive study should be conducted that also involves senior level managers.Originality/valueThere are relatively few prior studies of the factors addressed in this study which has sought to explore an under-research aspect of workplace behaviour.
A Multiyear Assessment of Irrigation Cooling Capacity in Agricultural and Urban Settings of Central Arizona

Published: May 2021

AbstractIrrigation water use associated with agricultural activities and urban green spaces provides substantial cooling effects and ameliorates heat in central Arizona. In this arid and semiarid area, evaluating the effect of irrigation on land surface temperature (LST) for different types of land use can improve decision making related to water resources management. In this work, we improved the simulation of urban and agricultural irrigation in the Variable Infiltration Capacity model through remotely sensed vegetation and irrigation parameters applied at high spatiotemporal resolution. We then conducted a multiyear (2004–2013) assessment of simulated LST with respect to ground observations and remotely sensed products finding overall good agreement. Overall, results show that irrigation of about 2 mm/day is required to reduce average daily LST by 1°C across the region. Numerical experiments with the validated model also reveal that irrigation leads to LST reductions of higher magnitude and greater spatial variability in croplands than in urban areas. Furthermore, we found that the role of interannual variations in cropping practices is more critical than year‐to‐year differences in climatic conditions for the evaluation of irrigation cooling capacity. Thus, remotely sensed vegetation products can serve a valuable purpose in quantifying LST reductions and irrigation requirements to achieve a target of heat amelioration.
The de Winter electrocardiographic pattern evolves to ST elevation in acute total left main occlusion: A case series

Published: May 2021

AbstractThe de Winter electrocardiographic (ECG) pattern was characterized by upsloping ST‐segment depressions, tall and positive symmetrical T waves in precordial leads. This rare ECG pattern was recognized as an indication of proximal left anterior descending artery occlusion. Less commonly, this ECG pattern was reported in association with occlusion of other coronary artery segments. We present three cases of the de Winter pattern associated with acute total left main occlusion. This pattern may evolve to ST elevation within hours of presentation. Widespread upsloping ST‐segment depressions from V2–V6, centered on V5 were observed in these patients.
Re‐evaluation of medical findings in alleged shaken baby syndrome and abusive head trauma in Norwegian courts fails to support abuse diagnoses

Published: May 2021

AbstractAimThe criteria for diagnosing abusive head trauma (AHT) are not well defined and this condition might be diagnosed on failing premises. Our aim was to review criminal AHT cases in Norwegian courts by scrutinising the underlying medical documentation.MethodsCases were identified in the data registry for Norwegian courts from 2004 to 2015. Documentation was obtained from relevant health institutions. The medical co‐authors first made independent evaluations of the documentation for each child, followed by a consensus evaluation.ResultsA total of 17 children (11 boys) were identified, all diagnosed as AHT by court appointed experts, 15 were infants (mean age 2.6 months). A high proportion (41.2%) was born to immigrant parents and 31.3% were premature. The medical findings could be explained by alternative diagnoses in 16 of the 17 children; 8 boys (7 infants – mean age 2.9 months) had clinical and radiological characteristics compatible with external hydrocephalus complicated by chronic subdural haematoma. Six children (five infants with mean age 2.1 months) had a female preponderance and findings compatible with hypoxic ischaemic insults.ConclusionThe medical condition in most children had not necessarily been caused by shaking or direct impact, as was originally concluded by the court experts.

AbstractThe objective of this experiment was to investigate the effects of low‐crude protein (CP) diets supplemented with rumen‐protected lysine and methionine on growth performance, nitrogen excretion, and carcass traits in Holstein steers. Steers consumed the following diets: (1) 17.2% CP on a dry‐matter basis during the early period (from 7 to 10 months of age) and 14.5% CP during the late period (from 10 to 18 months of age; CON, n = 4, initial body weight [BW] 238 kg), and (2) 14.4% CP during the early period and 11.4% CP during the late period (AA, n = 4, initial BW 243 kg). The AA diet contains rumen‐protected lysine and methionine. Except for CP intake, feed intake and body weight gain were not affected by dietary CP content. Total nitrogen excretion per metabolic BW tended to be lower (p < .10) in the early period and significantly lower (p < .05) in the late period with decreasing the feed CP content. Plasma urea nitrogen concentrations were lower in AA than CON. Carcass traits and total free amino acid contents of the longissimus thoracis muscle were not affected by dietary CP content. Adding rumen‐protected lysine and methionine to a low‐CP diet would reduce nitrogen excretion in fattening Holstein steers without affecting productivity.

AbstractObjectiveHypertension cure following adrenalectomy in unilateral primary aldosteronism is not guaranteed. Its likelihood is associated with pre‐operative parameters, which have been variably combined in six different predictive scoring systems. The relative performance of these systems is currently unknown. The objective of this work was to identify the best performing scoring system for predicting hypertension cure following adrenalectomy for primary aldosteronism.DesignRetrospective analysis in a single tertiary referral centre.PatientsEighty‐seven adult patients with unilateral primary aldosteronism who had undergone adrenalectomy between 2004 and 2018 for whom complete data sets were available to calculate all scoring systems.MeasurementsPrediction of hypertension cure by each of the six scoring systems.ResultsHypertension cure was achieved in 36/87 (41.4%) patients within the first post‐operative year, which fell to 18/71 (25.4%) patients at final follow‐up (median 53 months, P = .002). Analysis of receiver operating characteristic area under the curves for the different scoring systems identified a difference in performance at early, but not late, follow‐up. For all systems, the area under the curve was lower at early compared with late follow‐up and compared to performance in the cohorts in which they were originally defined.ConclusionsNo single scoring system performed significantly better than all others when applied in our cohort, although two did display particular advantages. It remains to be determined how best such scoring systems can be incorporated into the routine clinical care of patients with PA.
Predictors of and reasons for early discharge from inpatient withdrawal management settings: A scoping review

Published: May 2021

AbstractIssuesEarly discharges, also known as ‘against medical advice’ discharges, frequently occur in inpatient withdrawal management settings and can result in negative outcomes for patients. The purpose of this scoping review is to identify what is known about predictors of and reasons for the early discharge among adults accessing inpatient withdrawal management settings.ApproachMEDLINE, CINAHL, PsycINFO, ASSIA and EMBASE were searched, resulting in 2587 articles for screening. Title and abstract screening and full‐text review were completed by two independent reviewers. Results were synthesised in quantitative and qualitative formats.Key FindingsSixty‐two studies were included in this scoping review. All studies focused on predictors of early discharge, except one which only described reasons for the early discharge. Forty‐eight percent of studies involved retrospective review of health records data. The most frequently examined variables were demographics. Variables related to the treatment setting, such as referral source and treatment received, were examined less frequently but were more consistently associated with early discharge compared to demographics. Only six studies described patient reasons for the early discharge, which were retrieved via clinical documentation. The most common reasons for early discharge were dissatisfaction with treatment and family issues.Implications and ConclusionsMost demographic variables do not consistently predict early discharge, and reasons for early discharge are not well understood. Future studies should focus on the predictive value of non‐patient‐level variables, or conduct analyses to account for predictors of early discharge among different subgroups of people (e.g. by gender or ethnicity). Qualitative research exploring patient perspectives is needed.

Published: May 2021

AbstractMultiple stressors linked to anthropogenic activities can influence how organisms adapt and evolve. So far, a consensus on how multiple stressors drive adaptive trajectories in natural populations has not been reached. Some meta‐analysis reports show predominance of additive effects of stressors on ecological endpoints (e.g., fecundity, mortality), whereas others show synergistic effects more frequently. Moreover, it is unclear what mechanisms of adaptation underpin responses to complex environments. Here, we use populations of Daphnia magna resurrected from different times in the past to investigate mechanisms of adaptation to multiple stressors and to understand how historical exposure to environmental stress shapes adaptive responses of modern populations. Using common garden experiments on resurrected modern and historical populations, we investigate (1) whether exposure to one stress results in higher tolerance to a second stressor; (2) the mechanisms of adaptation underpinning long‐term evolution to multistress (genetic evolution, plasticity, evolution of plasticity); and (3) the interaction effects of multiple stressors on fitness (synergism, antagonism, additivity). We measure the combined impact of different levels of resource availability (algae) and biocides on fitness‐linked life‐history traits and interpret these results in light of historical environmental exposures. We show that exposure to one stressor can alter tolerance to second stressors and that the interaction effect depends on the severity of either stressor. We also show that mechanisms of adaptation underpinning phenotypic evolution significantly differ in single‐stress and multistress scenarios. These adaptive responses are driven largely by synergistic effects on fecundity and size at maturity, and additive effects on age at maturity. Exposure to multiple stressors shifts the trade‐offs among fitness‐linked life‐history traits, with a stronger effect on Daphnia populations when low‐resource availability and high biocide levels are experienced. Our study indicates that mitigation interventions based on single‐stress analysis may not capture realistic threats.
Unknown/enigmatic functions of extracellular ASC
Authors: de Souza Jean Gabriel , Starobinas Nancy , Ibañez Olga Celia Martinez 
Published: May 2021

AbstractApoptosis‐associated speck‐like protein containing a caspase recruit domain (ASC), encoded by PYCARD gene, is a 22 kDa small molecule, which aggregates into ASC specks during inflammasome activation. ASC protein is an adaptor protein present in several inflammasome complexes that performs several intra‐ and extracellular functions, in monomeric form or as ASC specks, during physiological and pathological processes related to inflammation and adaptive immunity. Extracellular ASC specks (eASC specks) released during cell death by pyroptosis can contribute as a danger signal to the propagation of inflammation via phagocytosis and activation of surrounding cells. ASC specks are found in the circulation of patients with chronic inflammatory diseases and have been considered as relevant blood biomarkers of inflammation. eASC amplifies the inflammatory signal, may induce the production of autoantibodies, transports molecules that bind to this complex, contributing to the generation of antibodies, and can induce the maturation of cytokines promoting the modelling of the adaptive immunity. Although several advances have been registered in the last 21 years, there are numerous unknown or enigmatic gaps in the understanding of the role of eASC specks in the organism. Here, we provide an overview about the ASC protein focusing on the probable roles of eASC specks in several diseases, up to the most recent studies concerning COVID‐19.
Infants' identification of gender in biological motion displays

Published: May 2021

AbstractInfants' knowledge of social categories, including gender‐typed characteristics, is a vital aspect of social cognitive development. In the current study, we examined 9‐ to 12‐month‐old infants' understanding of the categories “male” and “female” by testing for gender matching in voices or faces with biological motion depicted in point light displays (PLDs). Infants did not show voice–PLD gender matching spontaneously (Experiment 1) or after “training” with gender‐matching voice–PLD pairs (Experiment 2). In Experiment 3, however, infants were trained with gender‐matching face–PLD pairs and we found that patterns of visual attention to top regions of PLD stimuli during training predicted gender matching of female faces and PLDs. Prior to the end of the first postnatal year, therefore, infants may begin to identify gender in human walk motions, and perhaps form social categories from biological motion.

AbstractIntroductionAtrial fibrillation (AF) is the most common sustained cardiac arrhythmia, and results in significant morbidity and mortality. The Cox‐Maze IV procedure (CMP‐IV) has been shown to have excellent efficacy in returning patients to sinus rhythm, but there have been few reports of late follow‐up in sizable cohorts of patients with longstanding persistent AF, the most difficult type of AF to treat.Methods and ResultsBetween May 2003 and March 2020, 174 consecutive patients underwent a stand‐alone CMP‐IV for longstanding persistent AF. Rhythm outcome was assessed postoperatively for up to 10 years, primarily via prolonged monitoring (Holter monitor, pacemaker interrogation, or implantable loop recorder). Fine‐Gray regression was used to investigate factors associated with atrial tachyarrhythmia (ATA) recurrence, with death as a competing risk. Median duration of preoperative AF was 7.8 years (interquartile range: 4.0–12.0 years), with 71% (124/174) having failed at least one prior catheter‐based ablation. There were no 30‐day mortalities. Freedom from ATAs was 94% (120/128), 83% (53/64), and 88% (35/40) at 1, 5, and 7 years, respectively. On regression analysis, preoperative AF duration and early postoperative ATAs were associated with late ATAs recurrence.ConclusionDespite the majority of patients having a long‐duration of preoperative AF and having failed at least one catheter‐based ablation, the stand‐alone CMP‐IV had excellent late efficacy in patients with longstanding persistent AF, with low morbidity and no mortality. We recommend consideration of stand‐alone CMP‐IV for patients with longstanding persistent AF who have failed or are poor candidates for catheter ablation.

AbstractThe present study aims to explore rapid method for the detection of flavor substances in Ningxiang pork. Collect the longissimus dorsi samples of Ningxiang pigs with a left carcass weight 25–30 kg. After pretreatment, five factors affecting the volatile flavors of Ningxiang pork were detected: heat treatment time, the amount of saturated NaCl solution added, sample weight, equilibrium time and equilibrium temperature. The results showed that among the five factors, the heat treatment time had the greatest influence on the volatile flavors of Ningxiang pork and the equilibrium time had the least influence. The volatile substances of Ningxiang pork showed a trend of first increasing and then decreasing with the heat treatment time going on, the addition of saturated NaCl solution and the change of the sample weight. The overall flavor of Ningxiang pork increased with the increase of equilibrium temperature, and after equilibrating for 15 min, the overall flavor of Ningxiang pork was basically not affected by the equilibrium time. The optimal combination of conditions for rapid detection of Ningxiang pork flavor substances using electronic nose is sample weight 3 g, saturated NaCl solution 0.5 mL/g, heat treatment time 3 min and equilibrium time 15 min at 55°C.Practical ApplicationsTo establish an experimental method for the rapid detection of volatile flavor compounds in Ningxiang pork using an electronic nose, and to initially construct a fingerprint of Ningxiang pork flavor, with a view to providing more efficient and accurate ideas and methods for evaluating the quality and authenticity of Ningxiang pork.
