Tracking multiple pedestrians across multi-camera scenarios is an important part of intelligent video surveillance and has great potential application for public security, which has been an attractive topic in the literature in recent years. In most previous methods, artificial features such as color histograms, HOG descriptors and Haar-like feature were adopted to associate objects among different cameras. But there are still many challenges caused by low resolution, variation of illumination, complex background and posture change...

Although there is no remarkable change of anesthetics or anesthesia methods in recent years, several new technologies are used for safety management of cardiac, lung or thoracic surgery. Stroke volume variation (SVV) monitoring indicates SVV, a parameter to optimize fluid infusion and is used to avoid edema or congestive heart damage due to over hydration. SmartPilot View, a pharmacokinetic simulator during anesthesia, represents the measured effective site concentration of anesthetics and contributes the optimization of induction and maintenance of anesthesia...

There is limited evidence of how Australian low-to-middle income (AUD $40,000⁻$80,000) households maintain food security. Using a sequential explanatory mixed methods methodology, this study explored and compared the food security (FS) and insecurity (FIS) experiences of these households. An initial quantitative survey categorised participants according to food security status (the 18-item United States Department of Agriculture Household Food Security Survey Module) and income level to identify and purposefully select participants to qualitatively explore food insecurity and security experiences...

Mitigating greenhouse gases (GHGs) emissions from rice paddy (Oryza sativa L.) and balancing the trade-offs between reducing emission and sustaining food security have raised global concerns. A global meta-analysis of rice experimental data was conducted to assess changes in emissions of GHGs (CH4 and N2 O) and global warming potential (GWP) in response to improvements through 12 field management practices. The results indicated that changes in GWP were mainly attributed to CH4 emission even though N2 O emission was significantly affected by conversion of field management practices...

To date, numerous methods have been reported for the detection of organophosphorus pesticides (OP) due to their severe potential hazard to the environment, public health and national security. However, very few works have ever found that the signal loss of thiocholine (TCh) during electrochemical processing is a key factor leading to the low sensitivity of acetylcholinesterase (AChE)-based OP electrochemical sensing platforms. Herein, we propose an ultrasensitive detection method for multiple OPs including parathion-methyl, paraoxon, dimethoate and O,O-dimethyl-O-2,2-dichlorovinyl-phosphate using N-carbamoylmaleimide-functionalized carbon dots (N-MAL-CDs) as a nano-stabilizer...

Fungal pathogens are a growing worldwide concern. Declines in a number of economically and agriculturally important plant and animal species pose a significant threat to both biodiversity and food security. Although many effective antifungal agents have been identified, their toxicity often precludes their use with food products or sensitive animal species. This has prompted the exploration of natural products as effective treatment compounds. In the present study, several essential oils were tested for their capacity to limit the growth of the fungal pathogens Ascosphaera apis and Pseudogymnoascus destructans, the causative agents of chalkbrood disease among honey bee larvae and white-nose syndrome among bats, respectively...

Resuscitative hysterotomy is a daunting and rarely performed procedure in the emergency department (ED). Given the paucity of clinical exposure to this intervention, resuscitative hysterotomy is an ideal opportunity for simulation-mediated deliberate practice. The authors propose a novel training program using a homegrown, realistic, simulation device as a means to practice resuscitative hysterotomy. Two high-fidelity, tissue-based task-trainer models were constructed and tested on a convenience sample of 14 emergency medicine (EM) residents...

Background: An increase in self-harm emergencies after bariatric surgery have been documented, but understanding of the phenomenon is missing. Case presentation: The following case report describes a 26-year-old woman with obesity, who initiated self-harm behaviour after bariatric surgery. The patient reported that the self-harm was a substitute for binge eating, which was anatomically impeded after bariatric surgery.Pre-surgical psychosocial assessment revealed Anorexia Nervosa in youth, which had later migrated to Binge Eating Disorder...

Introduction: Robotic surgery is used in Europe and the US for oropharyngeal/hypopharyngeal cancers. Although robots can successfully perform procedures that are too delicate for surgeons and quickly learn accurate techniques, robotic surgery is not still authorized for the craniocervical region in Japan. In Japan, endoscopic laryngopharyngeal surgery (ELPS) is widely performed. Because oropharyngeal/hypopharyngeal cancer can be resected at an early stage, we have contributed to an improvement in the survival rate...

Nowadays, there is an increasing number of cameras placed on mobile devices connected to the Internet. Since these cameras acquire and process sensitive and vulnerable data in applications such as surveillance or monitoring, security is essential to avoid cyberattacks. However, cameras on mobile devices have constraints in size, computation and power consumption, so that lightweight security techniques should be considered. Camera identification techniques guarantee the origin of the data. Among the camera identification techniques, Physically Unclonable Functions (PUFs) allow generating unique, distinctive and unpredictable identifiers from the hardware of a device...

The development of crops with better growth under suboptimal phosphorus availability would improve food security in developing countries while reducing environmental pollution in developed countries. We tested the hypothesis that maize (Zea mays) phenotypes with greater lateral root branching density have greater phosphorus acquisition from low phosphorus soils. Recombinant inbred lines with either 'many short' (MS) or 'few long' (FL) lateral root phenotypes were grown under high and low phosphorus conditions in greenhouse mesocosms and in the field...

Food insecurity-the lack of consistent access to adequate amounts of food-remains a reality for many American families. Although children are usually protected from reductions in food intake even in households with low food security, about 8 percent of all households with children also experienced reduced food intake and disrupted eating patterns. The research on child food insecurity and family structure is limited and the findings are mixed. Given the increasing complexity of families in the U.S., combined with sustained high levels of food insecurity during the last decade, a closer examination of this relationship is warranted...

In this work, real life reclaimed plastic solid waste (PSW) secured from the municipal sector was mechanically recycled and compounded with virgin linear low density polyethylene (LLDPE). The compounding of the plastic film samples utilised the means of extrusion and blown filming to produce various formulations of the blends containing up to 100% (by weight) of the PSW in the examined specimens. The film samples were compared to market products used in the State of Kuwait where PSW accumulation presents a major obstacle...

We investigate various group-size distributions occurring in a situation where each group's resource is exposed to appropriation by other groups. The amount of appropriation depends on the size difference between groups. Our work focuses on the cases where the entire community isolates a small group or even an individual to maximize its gain. While people's basic motivation to form a group can be understood based on the group-size effect on multiplying a collective asset, sensitive factors that induce a asymmetric group distribution are the group efficiency and the ratio of secured assets to assets pending in a competition...

The Internet of Things (IoT) paradigm envisions a world where everyday things interchange information between each other in a way that allows users to make smarter decisions in a given context. Even though IoT has many advantages, its characteristics make it very vulnerable to security attacks. Ciphers are a security primitive that can prevent some of the attacks; however, the constrained computing and energy resources of IoT devices impede them from implementing current ciphers. This article presents the stream cipher Generador de Bits Pseudo Aleatorios (GBPA) based on Salsa20 cipher, which is part of the eSTREAM project, but designed for resource-constrained IoT devices of Class 0...

Objective To explore predictors of portal use by patients (registered portal users) with multiple chronic conditions according to demographic characteristics and use of specific features hypothesized to support self-management. Methods Two data sources were used in this analysis: electronic health records and 12 months of data from web server log files. Patients ( n = 500) included in the analysis were 45 years or older, registered portal users, and diagnosed with at least two chronic conditions. We fit a negative binomial regression model to predict portal use (number of logins) based on practice size and location, demographic characteristics, and use of specific portal features (secure messaging and patient-entered data)...

Optical characteristics of luminescent materials, including emission color (wavelength), lifetime, and excitation mode, play crucial roles in data communication and information security. Conventional luminescent materials generally display unicolor, unitemporal, and unimodal (occasionally bimodal) emission, resulting in low-level readout and decoding. The development of multicolor, multitemporal, and multimodal luminescence in a single material has long been considered to be a significant challenge. In this study, for the first time, the superior integration of colorful (red-orange-yellow-green), bitemporal (fluorescent and delayed), and four-modal (thermo-/mechano-motivated and upconverted/downshifted) emissions in a particular piezoelectric particle via optical multiplexing of dual-lanthanide dopants is demonstrated...
