Abstract
Molybdenum oxycarbide (MoOC) is a single-phase compound, which can serve as a potential anode for Li-ion batteries (LIBs) that integrates the merits of the high specific capacity of MoO2 and high conductivity of Mo2C. Herein, a novel architecture with N,P co-doped C nanofibers and MoOC nanodots is constructed from a one-step phosphorization of MoO
x
/aniline organic–inorganic hybrid. Ultrafine MoOC nanodots are well confined by N,P co-doped C nanofibers, which ensures fast Li+/electron transfer and good stability of the structure under repeated charge/discharge processes. When this unique hybrid is employed as an anode material for LIBs, promising Li+ storage properties are gained in terms of high specific capacity, superb rate and long-term cycling performance. The remarkable capacitive contribution facilitates the fast Li+ uptake/release. This work may shed light on the development of well-defined Mo-based anodes for advanced LIBs.
Application-specific nuclear medical in vivo imaging devices
Authors: Chaudhari Abhijit J , Badawi Ramsey D 
Published: March 2021

Abstract
Nuclear medical imaging devices, such as those enabling photon emission imaging (gamma camera, single photon emission computed tomography, or positron emission imaging), that are typically used in today’s clinics are optimized for assessing large portions of the human body, and are classified as whole-body imaging systems. These systems have known limitations for organ imaging, therefore application-specific devices have been designed, constructed and evaluated. These devices, given their compact nature and superior technical characteristics, such as their higher detection sensitivity and spatial resolution for organ imaging compared to whole-body imaging systems, have shown promise for niche applications. Several of these devices have further been integrated with complementary anatomical imaging devices. The objectives of this review article are to (1) provide an overview of such application-specific nuclear imaging devices that were developed over the past two decades (in the twenty-first century), with emphasis on brain, cardiac, breast, and prostate imaging; and (2) discuss the rationale, advantages and challenges associated with the translation of these devices for routine clinical imaging. Finally, a perspective on the future prospects for application-specific devices is provided, which is that sustained effort is required both to overcome design limitations which impact their utility (where these exist) and to collect the data required to define their clinical value.

Abstract
This study focuses on the effect of Ag2O/V2O5 substitution on the radiation shielding ability of tellurite glass system with the chemical composition of xAg2O + 40TeO2 + (60 − x)V2O5 with 0 < x < 50 mol%. FLUKA code was successfully employed for simulation the radiation interaction parameters of the glass systems. The results of the simulations were comparable with the predications of theory. Thereafter, several empirical equations were used to study the shielding ability of the glass systems against neutrons and charged particles. The results indicate that linear attenuation coefficient changes with energy and reaches maximum at 0.6 MeV (minimum at 10 MeV) with the values of 0.2806 (0.109), 0.3181 (0.121), 0.3771 (0.1498), 0.409 (0.168), 0.4588 (0.1911), and 0.5162 (0.2180) for x = 0, 10, 20, 30, 40, and 50 mol%, respectively. Beyond 5 MeV, the gamma ray constant was found in the order of

For all the charged particles, the projectile range was noted in the order of (R)x=0 > (R)x=10 > (R)x=20 > (R)x=30 > (R)x=40 > (R)x=50. Finally, we provide an extensive comparative study between AVT-glass systems and standard traditional materials. The obtained results suggest the sample of x = 50 mol% as the best photon, fast neutron and charged particle shield amongst the present glass systems. Hence, AVT6 could be used in radiation safety applications as a shield.
Invisible neutrino decay in precision cosmology
Authors: Barenboim Gabriela , Chen Joe Zhiyu , Hannestad Steen , Oldengott Isabel M. , Tram Thomas , Wong Yvonne Y.Y. 
Published: March 2021

Abstract
We revisit the topic of invisible neutrino decay in the precision cosmological context, via a first-principles approach to understanding the cosmic microwave background and large-scale structure phenomenology of such a non-standard physics scenario. Assuming an effective Lagrangian in which a heavier standard-model neutrino νH couples to a lighter one νl and a massless scalar particle ϕ via a Yukawa interaction, we derive from first principles the complete set of Boltzmann equations, at both the spatially homogeneous and the first-order inhomogeneous levels, for the phase space densities of νH, νl, and ϕ in the presence of the relevant decay and inverse decay processes. With this set of equations in hand, we perform a critical survey of recent works on cosmological invisible neutrino decay in both limits of decay while νH is ultra-relativistic and non-relativistic. Our two main findings are: (i) in the non-relativistic limit, the effective equations of motion used to describe perturbations in the neutrino-scalar system in the existing literature formally violate momentum conservation and gauge invariance, and (ii) in the ultra-relativistic limit, exponential damping of the anisotropic stress does not occur at the commonly-used rate ΓT =(1/τ0) (mνH/EνH)3, but at a rate ∼ (1/0) (mνH/EνH)5. Both results are model-independent. The impact of the former finding on the cosmology of invisible neutrino decay is likely small.
The latter, however, implies a significant revision of the cosmological limit on the neutrino lifetime τ0 from τ0
old ≳ 1.2 × 109 s (mνH/50 meV)3 to
τ0 ≳ (4 × 105 → 4 × 106) s (mνH/50 meV)5.

Abstract

Objective. To design and implement a setup for ex-vivo optical stimulation for exploring the effect of several key parameters (optical power and pulse duration), activation features (threshold, spatial selectivity) and recovery characteristics (repeated stimuli) in peripheral nerves. Approach. A nerve chamber allowing ex-vivo electrical and optical stimulation was designed and built. A 1470 nm light source was chosen to stimulate the nerve. A photodiode module was implemented for synchronization of the electrical and optical channels. Main results. Compound neural action potentials (CNAPs) were successfully generated with infrared light pulses of 200–2000 µs duration and power in the range of 3–10 W. These parameters determine a radiant exposure for stimulation in the range 1.59–4.78 J cm−2. Recruitment curves were obtained by increasing durations at a constant power level. Neural activation threshold is reached at a mean radiant exposure of 3.16 ± 0.68 J cm−2 and mean pulse energy of 3.79 ± 0.72 mJ. Repetition rates of 2–10 Hz have been explored. In eight out of ten sciatic nerves (SNs), repeated light stimuli induced a sensitization effect in that the CNAP amplitude progressively grows, representing an increasing number of recruited fibres. In two out of ten SNs, CNAPs were composed of a succession of peaks corresponding to different conduction velocities. Significance. The reported sensitization effect could shed light on the mechanism underlying infrared neurostimulation. Our results suggest that, in sharp contrast with electrical stimuli, optical pulses could recruit slow fibres early on. This more physiological order of recruitment opens the perspective for specific neuromodulation of fibre population who remained poorly accessible until now. Short high-power light pulses at wavelengths below 1.5 µm offer interesting perspectives for neurostimulation.

Published: March 2021

AbstractL-cysteine (L-cys) was used to coat ZnS quantum dots (QDs), which should benefit the improvement of water solubility and photoluminescence (PL) intensity of ZnS QDs. The impact of L-cys on the performances of ZnS QDs and the corresponding mechanism were discussed. It illustrated that L-cys modification didn’t change the crystal structure of ZnS QDs, and the mean diameter was enlarged as the content of L-cys was more. The results also displayed that the water solubility and PL intensity of samples coated with L-cys was better than that of the uncoated sample. The sample exhibited the maximal emission while the weight ratio of L-cys to QDs equaled 1.4:0.5, and it was 4.5 times as strong as ZnS sample. The result of the First-principles calculations indicated that L-cys shell layer is beneficial to prolong the lifetime of photon-generated carriers at surface location, which should lead to a reduction in the nonradiative recombination on the surface, and then the PL intensity will be enhanced. This work helps to investigate the surface modification of QDs modified by other organic compounds.

Performance evaluation of acceleration and jerk in unstable walking detection
Authors: Nurwulan N R , Selamaj G 
Published: March 2021

Abstract
Accelerometers have been widely used for human activity recognition as an early prediction of fall risk. However, acceleration data do not consider the force of gravity. Recent studies found that jerk, the derivative of acceleration, can describe the changes of body accelerations without considering the sensor orientation. This might overcome the issues caused by the displacement of the sensor, especially if a smartphone-based accelerometer is used as the sensor. This study aimed to compare the performance of acceleration and jerk in detecting postural stability using the postural stability index (PSI). Slightly different daily activity living such as walking on a flat surface, walking upstairs, and walking downstairs were chosen to compare the sensitiveness of acceleration and jerk in detecting the slight postural sway in healthy subjects. The collected data were pre-processed using the 8-modes of ensemble empirical mode decomposition (EEMD). Then, the multiscale entropy (MSE) of each intrinsic mode function (IMF) was calculated, and in the end, the PSI values were obtained. The paired t-test calculation using acceleration data showed that walking on a flat surface and walking downstairs are significantly different (p = 0.039). Whereas, the jerk dataset could not distinguish walking on a flat surface and walking downstairs (p = 0.228). From this result, it is evident that acceleration is better in recognizing human activities than jerk.
Comparative study of internal force in lecture buildings in Daerah Istimewa Yogyakarta between SNI 1726-2012 and 1726-2019 with the spectrum response method (2D)
Authors: Arifah S , Jaya D J , Widodo S 
Published: March 2021

Abstract
An earthquake is a sudden movement of the ground that comes from a wave in a place and spreads in all directions. In 2019 the Government of Indonesia has ratified a new standard on procedures for earthquake resistance planning for building and non-building structures, namely SNI 1726: 2019 as a revision of SNI 1726: 2012. The adoption of SNI 1726-2019 as a new standard has changed the scope of the procedure for calculating earthquakes to become wider so that it can follow the current developments. Earthquake loads on buildings were analyzed using dynamic response spectrum analysis. This study aims to compare the results of the calculation using the response spectrum using SNI 1726-2012 and SNI 1726-2019 in order to determine the safety of building that still use the old rules. The building structure is modeled on a lecture building with a height of 14,10 m in the Province of D.I Yogyakarta. The results of the research prove that the structure of the lecture building which still uses the old method must be rehabilitated so that it is able to withstand earthquake loads based on the new SNI 1726-2019 method. This occurs due to the discovery of new faults in Indonesia.
