Authors: Vimarlund Vivian , Borycki Elizabeth M. , Kushniruk Andre W. , Avenberg Kerstin 
Published: April 2021

Background: The ambient assisted living (AAL) market is rapidly becoming fundamental to the delivery of health and social care services for the elderly. Worldwide many different steps have been taken to increase the engagement of older adults with these technologies. Much of this work has focused on the development of novel digital services that increase wellbeing or tackle social challenges.
Aim: The aim of the study was to identify and describe the demands for AAL-services from the perspective of older adults. We also examine the challenges and needs of the ambient assisted living market using a needs based approach.
Method: An exploratory case study was conducted with an aim to capture information about older adults’ demands for AAL services. A survey was used to collect the data. The survey study respondents validated the results.
Results: The results of the study indicate that the area of AAL needs be studied from a multiple-sided market perspective. Our research suggests there is a need to describe and understand the factors that facilitate or constrain the implementation of services with focus on health and social care. There is also a need to describe and analyze the relationship between policy and practice and its effects on the AAL market. It is necessary to capture expressed demand, to identify market challenges at the macro level and to be able to understand how services should operate and serve older adults in practice. Such research is critical to the development of guidance for policy makers, suppliers and service providers.
Discussion: Older adults are asking for intelligent, assistive living solutions that help them to continue to live independent lives and remain socially included in their networks, associations, and communities. The elderly need services that stimulate and maintain their physical and intellectual capital. The development of innovative AAL environments is, however, a complex social process that involves the use and delivery of innovative ICT–based services. The implementation and use of AAL to support older adults involve service providers and elderly consumers.
Conclusions: The results of the study may be of interest to policy makers, entrepreneurs, technology suppliers, service providers and health and social care organizations, who are willing to innovate and influence the development of the AAL market through their choices and decisions.
Hollywood survival strategies in the post-COVID 19 era
Authors: Johnson Michael 
Published: April 2021

AbstractSince the arrival of the Coronavirus in the United States, Americans have been forced to quarantine themselves at home in dramatic fashion, unlike almost any other time in the nation’s history. Moreover, the American workforce has been equally impacted by virtue of state-imposed shutdowns that have affected innumerable businesses, including the Hollywood entertainment industry, which is the subject of this research. I examine how commercial entertainment conglomerates like AT&T, Comcast, Disney, ViacomCBS, and Fox have responded to mandatory closures for businesses that employ a human workforce upon whom they rely for their labor, and to human consumers they seek to distribute their film and television commodities to for profit. Using historical and discourse analyses in a political economic theoretical framework, I review contemporary reports about the economic conditions which have influenced the industry’s technological adaptation and innovation and argue that the Hollywood television and film industries will capitalize upon this current public health crisis as a motivator to adopt streaming platforms as the new preferred distribution mechanism of entertainment long after COVID 19 is a memory. This qualitative research examines the technological adaptations employed by these entertainment conglomerates to analyze (1) how the transition to streaming video on demand has occurred, and evaluates (2) what the adoption of these survival strategies mean for Hollywood’s long-term economic future and survival in a “digitally competitive” (Smith and Telang, 2017) marketplace.

SignificanceCancer therapies often fail to cure patients because a proportion of tumor cells withstand the toxic effects of chemotherapy. How surviving cancer cells recover from sublethal drug-induced stress is not known, but given that cellular resources are finite, stress resolution may come at the expense of less essential systems. Here, we studied the global cellular events of stress buildup and resolution in the bone marrow cancer, multiple myeloma, after proteasome inhibition, a commonly used therapeutic approach. Using a temporal multiomics approach, we delineate the unexpectedly complex and protracted changes myeloma cells undergo during stress resolution and demonstrate that recovering cells are more vulnerable to specific insults than acutely stressed cells. Thus, the findings may provide avenues for optimizing cancer therapies.
Taking it too far

Abstract
While teasing can cause offence, participants on television variety or game shows are generally expected to tolerate it. In this paper, we examine comments posted on YouTube in response to reports of a leaked recording of a television host in Taiwan swearing at and insulting a guest who teased the host about his “inability to take a defeat”. In so doing, we examine both the perceived limits of teasing (i.e. what is considered allowable and what goes too far), and the perceived limits of taking offence in response to teasing (i.e. what ways of indicating offence are considered allowable and what goes too far). We conclude that instances where there are disputes about whether taking offence is warranted by the teasing in question provides us with a useful lens to examine the role ideological discourses play in (re-)constituting the underlying moral fabric of social interaction.
Shrimp-mangrove integrated farming system in the Mekong Delta, Vietnam.
Authors: Tran Ngoc Hai 
Published: April 2021

Abstract

The integrated shrimp-mangrove system is one of the most important farming systems in the Mekong Delta, especially in the buffer zone of Ca Mau province, Vietnam. According to Decision No. 116/1999/QD-TTg of the Vietnam Central Government, farms could use up to 40% of the total area of the buffer zone along the coast for aquaculture, with 60% reserved for mangrove plantation and environmental protection. Currently the mangrove-shrimp farming system in Ca Mau occupies a total area of 47,500 ha, of which ponds (ditches) cover about 19,000 ha. Shrimp culture is based mainly on improved extensive methods that give productivities in the range of 200-400 kg ha-1 yr-1. In addition to shrimps, several other species such as mud crab, fish, and blood cockle are also stocked to diversify aquaculture production and ensure regular incomes. With newly issued policies and regulations for shrimp-mangrove farming systems, new opportunities are being created for further improvement and development of the system.
Amaranthus palmeri (Palmer amaranth).
Authors: Vélez-Gavilán Jeanine 
Published: April 2021

Abstract

Amaranthus palmeri is an annual herbaceous plant that is spreading rapidly beyond its native range in North America. It is considered the most invasive species of the dioecious amaranths and is ranked as one of the most troublesome weeds of various crops in the United States. The seeds are accidentally dispersed mainly though agriculture and the crop trade. This species is reported as causing serious impacts to the growth and yield of various crops, cotton, maize, soybean and sweet potatoes being among the most affected. A. palmeri is reported as invasive in the USA, Argentina and Brazil, due to the negative impact it has on agriculture. Although the native habitat of A. palmeri is arid desert areas of the southwest USA and the north of Mexico, it is spreading fast into higher latitudes and milder climates. Its success is attributed to a combination of high fecundity, fast and season-long germination, fast initial growth, high rates of photosynthesis, phenotypic plasticity, the vast amount of seeds produced per plant (up to 600,000), the ability to produce a large biomass and the development of herbicide resistance, including to the widely used glyphosate. The range of A. palmeri is also expected to expand due to climate change that will create suitable conditions for its establishment.
Diversifying Indian diets - challenges and opportunities.
Authors: Narayanan Rama 
Published: April 2021

Abstract
This review reiterates the lack of diversity in Indian diets, especially with regard to fruits, vegetables and pulses, resulting in a deficient intake of essential micro-nutrients. It also highlights the variations in nutrient intake across the life cycle determined by gender and other socioeconomic factors and life styles. It conceptualizes that issues of production, availability, affordable access, knowledge of nutrition and a balanced diet along with awareness be simultaneously addressed to help households to diversify diets. It suggests that a comprehensive district level quinquennial diet survey be undertaken across the country to help understand food choices, preferences and intake against the backdrop of existing policies. It postulates that adult nutrition literacy should take a problem-solving approach and address both men and women. Specific suggestions include increasing productivity of pulses, access to fruits and vegetables by way of better distribution and price control, support to farming households for production of food crops, diversifying the food basket in the public distribution system, increasing allocation for fruits and vegetables in direct feeding programmes and addressing the needs of adolescent boys in Government programmes.

Published: April 2021

ABSTRACT

Context:
East Asia is a crucial region in the global methane (CH4) budget, with significant contributions from the livestock sector. However, the long-term trend and spatial pattern of CH4 emissions from livestock in this region have not been fully assessed.
Methods:
Here, we estimate CH4 emissions from 10 categories of livestock in East Asia during 1961 – 2019 following the Tier 2 approaches suggested by the 2019 Refinement to the IPCC 2006 Guidelines.
Results:
livestock-sourced CH4 emission in 2019 was 13.22 [11.42 – 15.01] (mean [minimum%maximum of 95– confidence interval] Tg CH4 yr-1, accounting for an increase of 231% since 1961. The contribution of slaughtered populations to total emissions increased from 3% in 1961 to 24% in 2019. Spatially, the emission hotspots were mostly distributed in eastern China, South Korea, and parts of Japan, but they tend to shift northward after 2000.
Conclusion:
It is necessary to use dynamic emission factors and include slaughtered populations in the estimation of livestock CH4 emissions. Regions including Northern China, Mongolia, and South Korea deserve more attention in future CH4 mitigation efforts.

The effect of in situ oxygen and vacuum annealings on the low bandwidth manganite Gd1−x
Ca
x
MnO3 (GCMO) thin film with x = 0.4 was investigated. Based on the magnetic measurements, the AFM–FM coupling is suppressed by the vacuum annealing treatment via destroying the double exchange interaction and increasing the unit cell volume by converting the Mn4+ to the Mn3+. Consequently, resistance increases significantly compared to pristine film. The results are explained by a model obtained from the positron annihilation studies, where the vacuum annealing increased the annihilation lifetime in A and B sites due to the formation of vacancy complexes V
A,B–V
O, which was not the case in the pristine sample. The positron annihilation analysis indicated that most of the open volume defects have been detected in the interface region rather than on the subsurface layer and this result is confirmed by detailed x-ray reflection analysis. On the other hand, the effect of oxygen annealing on the unit cell volume and magnetization was insignificant. This is in agreement with positron annihilation results which demonstrated that the introduction of oxygen does not change the number of cation vacancies significantly. This work demonstrates that the modification of oxygen vacancies and vacancy complexes can tune magnetic and electronic structure of the epitaxial thin films to provide new functionalities in future applications.

Abstract
Polypyrrole (PPy) has high electrochemical activity and low cost, so it has great application prospects in wearable supercapacitors. Herein, we have successfully prepared polypyrrole/reduced graphene oxide (PPy/rGO) nanocomposite cotton fabric (NCF) by chemical polymerization, which exhibits splendid electrochemical performance compared with the individual. The addition of rGO can block the deformation of PPy caused by the expansion and contraction. The as-prepared PPy-0.5/rGO NCF electrode exhibits the brilliant specific capacitance (9300 mF cm−2 at 1 mA cm−2) and the capacitance retention with 94.47% after 10 000 cycles. At the same time, the superior capacitance stability under different bending conditions and reuse capability have been achieved. All-solid-state supercapacitor has high energy density of 167 μWh cm−2 with a power density of 1.20 mW cm−2. Therefore, the PPy-0.5/rGO NCF electrode has a broad application prospect in high-performance flexible supercapacitor fabric electrode.

Abstract
Core–shell gold nanorod (AuNR)@silver (Ag) nanostructures with their unique properties have gained enormous interest and are widely utilized in various applications including sensor systems, catalytic reactions, diagnosis, and therapy. Despite the recent progress, simple, effective, low-cost, and easy-to-tune strategies are heavily required to fabricate these nanoparticles (NP) systems. For this, we propose the employment of the polymer of 3,4-dihydroxyphenyl-L-alanine (L-DOPA) as a ligand molecule. A conformal thin layer of polymer of L-DOPA (PLDOPA) with its various functional groups enabled the reduction of silver ions onto the AuNRs and stabilization of the resultant NPs without using any surfactant, reducing agent, and seed material. The shape and growth model of the AuNR@Ag nanostructures was manipulated by simply tuning the amount of silver ions. This procedure created different NP morphologies ranging from concentric to acentric/island shape core–shell nanostructures. Also, even at the highest Ag deposition, the PLDOPA layer is still conformally present onto the Au@Ag core–shell NRs. The unique properties of NP systems provided remarkable characteristics in surface-enhanced Raman spectroscopy, catalytic activity, and cell viability tests.
On a fusion chain reaction via suprathermal ions in high-density H–11B plasma
Authors: Belloni Fabio 
Published: April 2021

AbstractThe11B(p,3α) fusion reaction is particularly attractive for energy production purposes because of its aneutronic character and the absence of radioactive species among reactants and products. Its exploitation in the thermonuclear regime, however, appears to be prohibitive due to the low reactivity of the H–11B fuel at temperatures up to 100 keV. A fusion chain sustained by elastic collisions between theαparticles and fuel ions, this way scattered to suprathermal energies, has been proposed as a possible route to overcome this limitation. Based on a simple model, this work investigates the reproduction process in an infinite, non-degenerate H–11B plasma, in a wide range of densities and temperatures which are of interest for laser-driven experiments (1024≲ne≲1028 cm−3,Te≲100 keV,Ti∼1 keV). In particular, cross section data for theα–p scattering which include the nuclear interaction have been used. The multiplication factor,k∞, increases markedly with electron temperature and less significantly with plasma density. However, even at the highest temperature and density considered, and despite a more than twofold increase by the inclusion of the nuclear scattering,k∞turns out to be of the order of 10−2only. In general, values ofk∞very close to 1 are needed in a confined scheme to enhance the suprathermal-to-thermonuclear energy yield by factors of up to 103or 104.
Robust and ultrafast state preparation by ramping artificial gauge potentials

Published: April 2021

Abstract
The implementation of static artificial magnetic fields in ultracold atomic systems has become a powerful tool, e.g. for simulating quantum-Hall physics with charge-neutral atoms. Taking an interacting bosonic flux ladder as a minimal model, we investigate protocols for adiabatic state preparation via magnetic flux ramps. Considering the fact that it is actually the artificial vector potential (in the form of Peierls phases) that can be experimentally engineered in optical lattices, rather than the magnetic field, we find that the time required for adiabatic state preparation dramatically depends on which pattern of Peierls phases is used. This can be understood intuitively by noting that different patterns of time-dependent Peierls phases that all give rise to the same magnetic field ramp, generally lead to different artificial electric fields during the ramp. As an intriguing result, we find that an optimal choice allows for preparing the ground state almost instantaneously in the non-interacting system, which can be related to the concept of counterdiabatic driving. Remarkably, we find extremely short preparation times also in the strongly-interacting regime. Our findings open new possibilities for robust state preparation in atomic quantum simulators.
Searching for spin-2 ULDM with gravitational waves interferometers
Authors: Armaleo Juan Manuel , López Nacir Diana , Urban Federico R. 
Published: April 2021

Abstract
The detection of gravitational waves from merging binaries has ushered in the era of gravitational wave interferometer astronomy. Besides these strong, transient, calamitous events, much weaker signals can be detected if the oscillations are nearly monochromatic and “continuous”, that is, coherent over a long time.
In this work we show that ultra-light dark matter of spin two, owing to its universal coupling α to Standard Model fields, generates a signal that is akin to but distinct from a continuous gravitational wave. We show that this signal could be detected with current and planned gravitational wave interferometers. In the event of a null detection, current facilities could constrain the coupling to be below α ∼ 10-7 for frequencies of tens of Hz, corresponding to dark matter masses around the 10-13 eV mark. Future facilities could further lower these upper limits and extend them to smaller masses down to 10-18 eV. These limits would be the most stringent bounds on the spin-2 Yukawa fifth force strength, parametrised by α, in the frequency ranges accessible by gravitational wave interferometers. The implementation of this type of searches for gravitational wave interferometers would therefore further our grasp of both dark matter and gravity.
On filaments, prolate halos and rotation curves
Authors: Zatrimaylov K. 
Published: April 2021

Abstract
We propose a simple geometrical mechanism for the flattening of galactic rotation curves, the local compression of field lines around their planes induced either by the presence of thin string-like objects at the centers of galaxies or by elongated dark-matter halos, and elaborate on its possible role in Nature. We fit 83 rotation curves from the SPARC database with logarithmic potentials produced by a thin "wire" at the origin and then, after selecting 2 galaxies that yield the most interesting fits, analyze them with an alternative model, deformed versions of two popular models of dark-matter halos. Our conclusion is that the presence of a filament clearly improves the fit quality in a number of cases, while bulged dark matter profiles have a lesser effect. If taken at face value, these results would imply the presence of elongated mass distributions away from the galactic plane in a number of galaxies, and may also have some indirect impact on the controversy between cold dark matter (CDM), self-interacting dark matter (SiDM), and modified Newtonian dynamics (MOND).
