A Hybrid Control Framework for Chemical Processes with Long Time Delay: Theory and Experiments.

This paper proposes a hybrid control framework based on internal model concepts, sliding mode control methodology, and fractional-order calculus theory. As a result, a modified Smith predictor (SP) is proposed for nonlinear systems with significant delays. The particular predictive approach enhances the sliding mode control (SMC) controller's transient responses for dead-time processes, and the SMC gives the predictive structure robustness for model mismatches by combining the previous methods with fractional order concepts; the result is a dynamical sliding mode controller.

The influence of social identity on attitudes toward wildlife.

Wildlife conservation depends on supportive social as well as biophysical conditions. Social identities such as hunter and nonhunter are often associated with different attitudes toward wildlife. However, it is unknown whether dynamics within and among these identity groups explain how attitudes form and why they differ.

Embedding Fe(0) electrocoagulation in a biologically active As(III) oxidising filter bed.

Long-term consumption of groundwater containing elevated levels of arsenic (As) can have severe health consequences, including cancer. To effectively remove As, conventional treatment technologies require expensive chemical oxidants to oxidise neutral arsenite (As(III)) in groundwater to negatively charged arsenate (As(V)), which is more easily removed. Rapid sand filter beds used in conventional aeration-filtration to treat anaerobic groundwater can naturally oxidise As(III) through biological processes but require an additional step to remove the generated As(V), adding complexity and cost.

Wherever I may roam-Human activity alters movements of red deer (Cervus elaphus) and elk (Cervus canadensis) across two continents.

Human activity and associated landscape modifications alter the movements of animals with consequences for populations and ecosystems worldwide. Species performing long-distance movements are thought to be particularly sensitive to human impact. Despite the increasing anthropogenic pressure, it remains challenging to understand and predict animals' responses to human activity.

Integrating basic and applied research to estimate carnivore abundance.

A clear connection between basic research and applied management is often missing or difficult to discern. We present a case study of integration of basic research with applied management for estimating abundance of gray wolves (Canis lupus) in Montana, USA. Estimating wolf abundance is a key component of wolf management but is costly and time intensive as wolf populations continue to grow.

Evaluating the summer landscapes of predation risk and forage quality for elk ().

The recovery of carnivore populations in North American has consequences for trophic interactions and population dynamics of prey. In addition to direct effects on prey populations through killing, predators can influence prey behavior by imposing the risk of predation. The mechanisms through which patterns of space use by predators are linked to behavioral response by prey and nonconsumptive effects on prey population dynamics are poorly understood.

Short sleep duration and dementia: a narrative review.

Short sleep duration has been linked to the development of neurocognitive disorders. Still, current evidence for this relationship is conflicting. In this review, we summarize evidence regarding the relationship between short sleep duration and neurocognitive disorders, which shows that short sleep duration increases the risk of incident major neurocognitive disorders beginning as early as midlife.

Video Conferencing Dysmorphia: Assessment of Pandemic-Related Body Dysmorphia and Implications for the Post-lockdown Era.

Background: The coronavirus 2019 (COVID-19) pandemic has led to global effects on human interaction and mental health. The most drastic changes are seen in ways people continue to stay connected with each other. Video-conferencing applications like Zoom gained popularity and have become the primary means of communication for social or work events and meetings.

COVID-19 vaccine hesitancy in patients with mental illness: strategies to overcome barriers-a review.

Background: People with mental health problems are at particular risk both for infection with COVID-19 and for more severe course of illness. Understanding COVID-19 vaccine hesitancy is crucial in promoting vaccine acceptance among people with mental health diagnoses. This review aims to identify the prevalence and discuss factors associated with COVID-19 vaccine hesitancy among the mentally ill population.

Economical defence of resources structures territorial space use in a cooperative carnivore.

Ecologists have long sought to understand space use and mechanisms underlying patterns observed in nature. We developed an optimality landscape and mechanistic territory model to understand mechanisms driving space use and compared model predictions to empirical reality. We demonstrate our approach using grey wolves ().

Treatment and Management of Sexual Disinhibition in Elderly Patients With Neurocognitive Disorders.

Sexual disinhibition is uncommon but challenging symptom to address in elderly patients with neurocognitive disorders. Due to the lack of large-scale studies, there is no gold standard treatment for sexual disinhibition, and treatment is largely left up to the discretion of the provider based on the severity and onset of the patient's symptoms. A review was conducted to investigate the non-pharmacological and pharmacological interventions for treating this condition.

Emerging Needs and Viability of Telepsychiatry During and Post COVID-19 Era: A Literature Review.

The coronavirus disease 2019 (COVID-19) pandemic has resulted in nationwide stay-at-home orders in an effort to slow the spread severely impacting the healthcare sector. Telepsychiatry provides a platform bridging the gap through advanced technologies connecting mental health providers and patients who need their services, overcoming previous barriers of great distances, lack of transportation, and even time constraints. The most obvious benefit is increased accessibility to mental healthcare, especially in underserved and remote areas where there is no easy access for in-person care.

Benzodiazepine Misuse: An Epidemic Within a Pandemic.

Coronavirus disease 2019 (COVID-19) had deleterious effects on patients with mental health problems and several studies have shown a spike in the rates of depression, insomnia, and post-traumatic stress disorder. Anxiety and insomnia rates have also increased among both the general public and health care professionals. Benzodiazepines are some of the most commonly used drugs in the treatment of anxiety and insomnia.

Lithium-Associated Hyperparathyroidism Followed by Catatonia.

Objective: To familiarize the medical community with the less common adverse effects of lithium on parathyroid function, we present a case of lithium-associated hyperparathyroidism followed by the development of new-onset catatonia in a patient with schizoaffective disorder.

Methods: To allow for the safe resumption of lithium, the patient received laboratory screening of serum lithium, blood urea nitrogen, serum creatinine, calcium, and thyroid-stimulating hormone levels. The hypercalcemia was evaluated by measuring parathyroid hormone (PTH), ionized calcium, and 25-hydroxy vitamin D levels.

Evidence of economical territory selection in a cooperative carnivore.

As an outcome of natural selection, animals are probably adapted to select territories economically by maximizing benefits and minimizing costs of territory ownership. Theory and empirical precedent indicate that a primary benefit of many territories is exclusive access to food resources, and primary costs of defending and using space are associated with competition, travel and mortality risk. A recently developed mechanistic model for economical territory selection provided numerous empirically testable predictions.

Elk migration influences the risk of disease spillover in the Greater Yellowstone Ecosystem.

Wildlife migrations provide important ecosystem services, but they are declining. Within the Greater Yellowstone Ecosystem (GYE), some elk Cervus canadensis herds are losing migratory tendencies, which may increase spatiotemporal overlap between elk and livestock (domestic bison Bison bison and cattle Bos taurus), potentially exacerbating pathogen transmission risk. We combined disease, movement, demographic and environmental data from eight elk herds in the GYE to examine the differential risk of brucellosis transmission (through aborted foetuses) from migrant and resident elk to livestock.

Effect of supernatant water level on As removal in biological rapid sand filters.

Current groundwater treatment facilities, mostly relying on aeration-filtration configurations, aim at the removal of iron (Fe), ammonia (NH ) and manganese (Mn). However, recently water companies expressed the ambition to also reduce arsenic (As) concentrations in these rapid sand filters. The aim of this study was to investigate the effect of the Fe oxidation state entering a biological filter bed on As removal.

As(III) removal in rapid filters: Effect of pH, Fe(II)/Fe(III), filtration velocity and media size.

In the top layer of aerated rapid sand filtration systems, uncharged As(III) is biologically converted to charged As(V). Subsequently, the main removal mechanism for As(V) is adsorption onto oxidised, flocculated Fe(III) (hydrous ferric hydroxides; HFO). The aim of this research was to understand the interactions between As and Fe in biologically active rapid filter columns and investigate the effect of different operational modes on Fe removal to subsequently promote As removal.

As(III) oxidation by MnO during groundwater treatment.

The top layer of natural rapid sand filtration was found to effectively oxidise arsenite (As(III)) in groundwater treatment. However, the oxidation pathway has not yet been identified. The aim of this study was to investigate whether naturally formed manganese oxide (MnO), present on filter grains, could abiotically be responsible for As(III) oxidation in the top of a rapid sand filter.

Fate of low arsenic concentrations during full-scale aeration and rapid filtration.

In the Netherlands, groundwater treatment commonly consists of aeration, with subsequent sand filtration without using chemical oxidants like chlorine. With arsenic (As) concentrations well below the actual guidelines of 10 μg As/L, groundwater treatment plants have been exclusively designed for the removal of iron (Fe), manganese and ammonium. The aim of this study was to investigate the As removal capacity at three of these groundwater treatment plants (10-26 μg As/L) in order to identify operational parameters that can contribute to lowering the filtrate As concentration to <1 μg/L.

Determining Occurrence Dynamics when False Positives Occur: Estimating the Range Dynamics of Wolves from Public Survey Data.

Large-scale presence-absence monitoring programs have great promise for many conservation applications. Their value can be limited by potential incorrect inferences owing to observational errors, especially when data are collected by the public. To combat this, previous analytical methods have focused on addressing non-detection from public survey data.

Prey risk allocation in a grazing ecosystem.

Understanding the behaviorally mediated indirect effects of predators in ecosystems requires knowledge of predator-prey behavioral interactions. In predator-ungulate-plant systems, empirical research quantifying how predators affect ungulate group sizes and distribution, in the context of other influential variables, is particularly needed. The risk allocation hypothesis proposes that prey behavioral responses to predation risk depend on background frequencies of exposure to risk, and it can be used to make predictions about predator-ungulate-plant interactions.

Doctor-shopping patients and users of alternative medicine among Japanese primary care patients.

To describe the clinical characteristics of patients with doctor-shopping behavior (doctor-shopping patients) and users of alternative medicine among Japanese primary care patients, 1088 patients from the general medicine outpatient clinic of a medical school hospital answered an original questionnaire and 30-item General Health Questionnaire (GHQ). A random sample of patients was questioned in accordance with the Diagnostic Interview Schedule modified for use in Japan (DIS-JM). Twenty-three percent of these patients met our criteria for doctor-shopping patients, and 7.
