Authors: Forcey Dana S. , Dyer Jessamy C. , Hopper Ingrid K. 
Published: October 2022

Objective To investigate demographics, clinical patterns and outcomes of rapid response reviews in hospital, reviewing indications for and outcomes of rapid response reviews initiated for clinical concern and to understand the role of clinical concern in identifying the deteriorating patient and at-risk patient populations. Method This was a retrospective analysis of General Medical inpatients at Alfred Hospital from 1 January 2018 to 31 July 2020. Data extraction from electronic medical records identified patients who had a rapid response review during admission. Demographic and clinical data, investigations and clinical outcomes from rapid response reviews were investigated. Comparisons were performed using χ2 or Fisher’s exact test where appropriate. Odds ratios and 95% confidence intervals were calculated for factors associated with rapid response reviews for clinical concern and clinical outcomes. Results There were 10 797 admissions of 7409 individual patients. There were 2359 rapid response reviews during the study period, occurring in 13% of admissions. Patients were majority female (50.4%), and the median age was 79 ± 17.6 years. Rapid response reviews were for cardiovascular (46.8%), respiratory (25.3%) and neurological (14.3%) indications. A total of 11% of rapid response reviews (n = 258) were for clinical concern. Inpatient falls accounted for a significant proportion of rapid response reviews for clinical concern. Reviews were more common in older patients, those admitted after-hours, and patients with disabilities. The latter group were more likely to have rapid response reviews for clinical concern. Rapid response reviews initiated for clinical concern were more likely than those initiated for standard criteria to change patients’ clinical status, particularly the withdrawal of active management. Conclusions Rapid response reviews for clinical concern are important triggers to identify clinical deterioration in vulnerable patients. Reviews were initiated for clinical concern were more likely than those initiated for standard criteria to result in a change in patients’ resuscitation status and care trajectory. Clinician concern, even when prompting review for parameters outside of standard clinical review criteria, remains an important factor in recognising the deteriorating patient.

Crinum flaccidum Herb. is widespread across southern and eastern Australia, but suffers from taxonomic uncertainty. This ambiguity is in part due to widespread hybridisation in the genus, but also morphological variability within and among populations. Morphological and molecular analyses of the complex using 24 morphological characters and 59 chloroplast coding and non-coding regions (~50 000 bp) provided support for the separation of C. flaccidum from C. luteolum Traub & L.S.Hannibal ex Traub, with the latter representing populations from the Flinders Ranges and Lake Eyre Basin. Within Crinum flaccidum, there was greater inferred genetic structure at the population level for New South Wales flood plain accessions, compared with South Australian populations from along the Murray River. The greater structure of the South Australian populations is theorised to be attributed to lower seed-dispersal rates leading to lower gene flow.
Same person, different platform

AbstractThe importance of digital data in forensic contexts has been increasing continuously (e.g.,Grant 2013;Layton, Watters & Dazeley 2010;Wright 2013), with individuals holding an average of 8.5 different social media accounts in 2018 (Statista 2021a). Even though numerous studies have investigated registers on social media platforms (e.g.,Seargeant & Tagg 2014;Zappavigna 2013), it has rarely been attempted to describe individual styles of one and the same person on different platforms – a research gap this paper attempts to address with the help of an exploratory hypothesis-generating study. The data is drawn from Instagram and Twitter, and comprises 1,800 posts from three media representatives and/or writers that hold accounts with both platforms. The results of the analysis suggest that the use of some features (e.g., emoji, hashtags) is strongly influenced by the respective platforms, while other features (e.g., patterns of punctuation, use of types of speech acts) remain stable and thus offer promising avenues for authorship analysis.
Solidification structures and phases in wire arc additive manufactured C250 maraging steel
Authors: Guo Lulu , Zhang Lina , Andersson Joel , Ojo Olanrewaju 
Published: October 2022

Multiple layers of C250 maraging steel were deposited into a single-wall structure by using wire arc additive manufacturing (WAAM). The microstructural characteristics of the as-deposited C250 steel, in terms of solidification structures and phases, were investigated by using optical microscopy, scanning electron microscopy, and transmission electron microscopy (TEM). The results show that lath martensite and austenite phases are formed in the as-deposited C250 steel. Apart from these two phases, Laves phase Fe2Ti particles, which have not been reported in C250 steel, are also observed in the C250 steel produced by the WAAM process. TEM analysis does not reveal the formation of strengthening precipitates in the as-built C250 steel, which is further confirmed by hardness measurement. GRAPHICAL ABSTRACT

The effect of boson–boson interaction on the bipolaron formation
Authors: Jager J , Barnett R 
Published: October 2022

Abstract
Impurities immersed into a surrounding ultra-cold Bose gas experience interactions mediated by the surrounding many-body environment. If one focuses on two impurities that are sufficiently close to each other, they can form a bipolaron pair. Here, we discuss how the standard methods based on linearizing the condensate field lead to results only valid in the weak coupling regime and for sufficiently large impurity separations. We show how those shortcomings can be remedied within the Born–Oppenheimer approximation by accounting for boson–boson interactions already on the mean-field level.
A multifunctional metasurface with broadband absorption and high-efficiency transmission polarization conversion
Authors: Fu Yang , Yang Helin , Cheng Houyuan , Liu Shanshan , Li Shangru , Zhang Aidong , Wen Dinge 
Published: October 2022

Abstract
In this paper, a polarization-sensitive absorption and transmission polarization conversion multifunctional metasurface is designed. Based on the principle of Fabry-Borot antenna, the modulation of electromagnetic waves with different polarizations is realized. Receiver-transmitter structure consisting of rectangular metal patches on the front and back sides . Cross-polarization conversion of Y-polarized waves was achieved at 8.9–15.2 GHz. In combination with the open-slit elliptical structure, selective absorption of X-polarization can be achieved, thus realizing the radar cross-section(RCS) reduction of the target. The absorption operates in the frequency band of 8.3–13.9 GHz. Electromagnetic waves of different polarizations do not affect each other in the modulation of the same structure and operate in almost the same frequency band. To verify the proposed structure, the relevant parameters were optimized and measured. The experimental results match with the simulation results, and the design can be used for radome and electromagnetic stealth.

Published: October 2022

Abstract
High-pressure structure transition of nontoxic all-inorganic MHP CsSnBr3 was fully explored up to 15 GPa using an advanced structure search technique CALYPSO combined with first-principles calculations. Besides the known orthorhombic Pnma ground state phase, two high-pressure semiconducting Cmcm and P21/m phases of CsSnBr3 were firstly uncovered above 2.37 and 6.8 GPa, respectively. Both phase transitions of the Pnma → Cmcm at 2.37 GPa and Cmcm → P21/m at 6.8 GPa were characterized as first order with a volume reduction of 4.7% and 10.8%. The occurrences of high-pressure Cmcm and P21/m phases follow the enhanced distortions of Sn–Br polyhedrons and increased coordination of Sn atoms from 6 to 8 at elevated pressures. Compared to the direct band gap of the ambient-pressure Pnma phase, the Cmcm and P21/m phases exhibit a larger indirect band gap of 2.347 and 3.143 eV, respectively, originating from the movement away from the Fermi level of conduction bands driven by the twisting of Sn–Br polyhedrons under pressure. The light absorption performances of two high-pressure phases in comparison with the Pnma phase were studied by the calculated optical absorption coefficients.
Self-tuning of the cosmological constant in brane-worlds with P(X,ϕ)
Authors: Lacombe Osmin , Mukohyama Shinji 
Published: October 2022

AbstractWe revisit the idea of self-tuning the observed cosmological constant to a vanishing value and promote it to a selection criterion of brane-world models, in which our Universe is described by a 3-brane embedded in a5dbulk. As a concrete setup, we consider a bulk scalar fieldϕdescribed by a general LagrangianP(X,ϕ) withX= -(∂ϕ)2/2. By requiring that the model enforces the4dcurvature of the maximally symmetric 3-brane world-volume to vanish independently of the4deffective vacuum energy, only two possibilities remain: one with a canonical bulk kinetic term and the other with an unconventional bulk kinetic term similar to a Cuscuton field. Further demanding the absence of bulk singularity, the latter is selected as a unique possibility within the class of models. At the background level, the solution can accommodate any warp factor profile free from bulk singularity and with a finite effective4dPlanck mass. In a cosmological context, our solution would describe our (almost) flat Universe at late times, with a bulk warp factor profile expected to be determined by the evolution of the Universe before dilution of the matter fields by cosmic expansion. Eventually, a simple analysis is performed in the bulk showing no obvious instability around the background solution. A full stability analysis taking into account brane bending modes is nevertheless necessary and left for future work.

Abstract
The continuous wave laser characteristics of a Tm:GdScO3 laser were researched in this work. Under the absorbed pump power of 19.11 W, a maximum output power of 4.41 W was obtained at 1978 nm, corresponding to the slope efficiency of 28.25%. With a quartz birefringent filter (BF), a broad wavelength tunable range from 1845 nm to 2006 nm was obtained, for the first time. Then, a long-pass filter was used to replace the quartz BF. A maximum output power of 3.21 W was obtained at 2002 nm, with the slope efficiency of 21.98%. The beam quality factors M
2 for horizontal and vertical directions were 1.14 and 1.11, respectively.
Semiconductor laser and polarization modulator for W-band signal generation
Authors: Yao Cheng-Kai , Manie Yibeltal Chanie , Huang Jun-Han , Peng Peng-Chun 
Published: October 2022

Abstract
A photonic microwave harmonic up-conversion is experimentally demonstrated using the local oscillator (LO) to directly modulate the distributed feedback laser and externally modulate the polarization modulator simultaneously. By feeding the initial radio frequency signal generated by the LO into the system, the second and fourth harmonic photonic microwaves are eventually available through the separation of the polarization beam splitter. The steady second and fourth harmonic photonic microwaves have a linewidth of about 100 Hz and a discrepancy of up to 60 dB between the central peak and the noise floor. Undesired harmonics and sidebands in the 30 GHz, 60 GHz, and 80 GHz fourth harmonic photonic microwaves can be suppressed without the use of optical amplifiers, resulting in a clear display of both tones. The single-sideband (SSB) phase noise of this proposed system adds about 6 dB of SSB phase noise in each cumulative harmonic, which is close to the ideal state.

Abstract
Since coronaviruses can remain infectious on different inanimate surfaces for several hours or even days, the possibility of indirect fomite transmission through infected objects and surfaces cannot be ruled out. We describe a method for the photodynamic disinfection of inanimate surfaces infected with severe acute respiratory syndrome coronavirus 2, Omicron variant strain. Application of only 5 µM photosensitizer octakis(cholinyl)zinc phthalocyanine followed immediately by 7 min irradiation with light emitting diode (LED) light 692 nm (12.5 mW cm−2) results in complete inactivation of the virus on polystyrene and glass surfaces, while 10 min irradiation lead to complete eradication of the virus also on Al-foil and medical mask fabric. A photodynamic technique is being considered to combat the spread of coronaviruses.
Method of dynamic resonance tuning in spintronics of nanosystems
Authors: Yukalov V I , Yukalova E P 
Published: October 2022

Abstract
A method is advanced allowing for fast regulation of magnetization direction in magnetic nanosystems. The examples of such systems are polarized nanostructures, magnetic nanomolecules, magnetic nanoclusters, magnetic graphene, dipolar and spinor trapped atoms, and quantum dots. The emphasis in the paper is on magnetic nanomolecules and nanoclusters. The method is based on two principal contrivances: First, the magnetic sample is placed inside a coil of a resonant electric circuit creating a feedback field, and second, there is an external magnetic field that can be varied so that to dynamically support the resonance between the Zeeman frequency of the sample and the natural frequency of the circuit during the motion of the sample magnetization. This method can find applications in the production of memory devices and other spintronic appliances.
Erroneous use of Statistics behind Claims of a Major Solar Role in Recent Warming
Authors: Richardson Mark T. , Benestad Rasmus E. 
Published: October 2022

Abstract
In a study that attempted to relate solar and human activity to Earth's recent temperature change, Connolly et al. committed a basic error in the choice of statistical methods and so overreported the effect of the Sun. A major theme of their study was that there are many data sets of past solar activity, and some of these allegedly provide statistical evidence of “most of the recent global warming being due to changes in solar activity.” We avoid methods that are known to give inaccurate results and show that for 1970–2005 Northern Hemisphere land the corrected solar attribution fraction is −7% to +5%, compared with values of up to 64% reported in Connolly et al. Their higher values are entirely due to mistaken application of statistics. Unfortunately, we cannot test truly “recent” global warming since most of their solar data sets end before 2015, and two finish in the 1990s, but all tested post-1970 periods show similarly small solar contributions. The solar-climate linkage is an area of fascinating and ongoing research with rigorous technical discussion. We argue that instead of repeating errors, they should be acknowledged and corrected so that the debate can focus on areas of legitimate scientific uncertainty.
Athermal fluctuations in three dimensional disordered crystals
Authors: Maharana Roshan 
Published: October 2022

Abstract
We study jammed near-crystalline materials composed of frictionless spheres in three dimensions. We analyse the fluctuations in positions and forces produced by small polydispersity in particle sizes. We generalize a recently developed perturbation expansion about the crystalline ordered state to three dimensional systems. This allows us to exactly predict changes in positions and forces as a response to the changes in particle radii. We show that fluctuations in forces orthogonal to the lattice directions are highly constrained as compared to the fluctuations along lattice directions. Additionally, we analyse the correlations in the displacement fields produced by the microscopic disorder, which we show displays long ranged behaviour.
Extreme sea level rise along the Indian Ocean coastline: observations and 21st century projections

Published: October 2022

Abstract
Anthropogenic sea-level rise poses challenges to coastal areas globally. The combined influence of rising mean sea level (MSL) and storm surges exacerbate the extreme sea level (ESL). Increasing ESL poses a major challenge for climate change adaptation of nearly 2.6 billion inhabitants in the Indian Ocean region. Yet, knowledge about past occurrences of ESL and its progression is limited. Combining multiple tide-gauge and satellite-derived sea-level data, we show that ESL has become more frequent, longer-lasting and intense along the Indian Ocean coastlines. We detect a 2–3-fold increase in ESL occurrence, with higher risk along the Arabian Sea coastline and the Indian Ocean Islands. Our results reveal that rising MSL is the primary contributor to ESL increase (more than 75%), with additional contribution from intensifying tropical cyclones. A two-fold increase in ESL along the Indian Ocean coastline is detected with an additional 0.5 °C warming of the Indian Ocean relative to pre-industrial levels. Utilizing the likely range (17th–83rd percentile as the spread) of Intergovernmental Panel on Climate Change MSL projections with considerable inter-model spread, we show that the Indian Ocean region will be exposed annually to the present-day 100 year ESL event by 2100, irrespective of the greenhouse-gas emission pathways, and by 2050 under the moderate-emission-mitigation-policy scenario. The study provides a robust regional estimate of ESL and its progression with rising MSL, which is important for climate change adaptation policies.
5G Field level measurement for human exposure assessment: A lesson for 6G
Authors: Migliore M D 
Published: October 2022

Abstract
Field level measurement for human exposure assessment is an important and sometimes underestimated problem. The aim of this work is to describe the problem of field level measurement for the assessment of human exposure from 2G to 5G, showing the growing difficulties caused by an increasing flexibility of cellular communication systems. If on the one hand this flexibility allowed higher performances, on the other hand it made the estimation of the electromagnetic field more and more complex. 5G field level measurement for human exposure assessment represents a formidable complex problem, currently under study to identify reliable and low-cost methods. Vendors have recently understood this problem and have included a control on the power density radiated by antennas in 5G systems, known as the ”power lock” function. It is worth noting that for the first time a sophisticated power control is introduced in base stations (BS) for the human exposure target. This should be a lesson for the development of 6G, suggesting a safety-on-design approach to human exposure for the next generation of personal communication systems.

Authors: Șorecău M , Șorecău E , Sârbu A , Helbet R , Bechet P 
Published: October 2022

Abstract
This paper presents preliminary research for the implementation and testing of a Software Defined Radio (SDR) sensor with electromagnetic spectrum monitoring capabilities for measuring signals specific to the Long-TermEvolution (LTE) mobile communications standard. The proposed sensor is developed on the ADALM Pluto SDR platform - and is designed to acquire a bandwidth of at least 20MHz. To determine the spatial extent of the measurements, the sensor also includes a GPS (Global Positioning System) module. The hardware control of the sensor is performed both in stationary variant using a laptop and in mobile mode using a low-cost module - Raspberry Pi. Present findings suggest that the designed SDR solution represents a reliable and low-cost alternative for real-time spectrum monitoring of wideband signals like the case of 4G-specific signals. The cost of the whole implemented monitoring system is about EUR 330.

Abstract
Infrared (IR) thermography enabled by a small camera attached to a mobile phone is used in the present research for the determination of the heating dynamics of biological liquid samples exposed to 2.3 GHz continuous wave. The methodology is presented and analysed and some relevant examples are Figured out. Differences in electromagnetic field dissipation are nicely emphasized proving that microwaves dosimetry applied to surfaces, if enough resolution and frame frequency is enabled, may represent a valuable tool in observing heating dynamics of the exposed surfaces even at the microscale.

Abstract
As conventional fossil fuel systems release toxicants into the atmosphere, humanity is increasingly moving towards sustainability, towards using products that do not cause negative effects on the environment, have a long service life and offer multiple benefits. Solar air heating systems are increasingly used in household applications, even in industrial ones at times. The principle of operation of systems of this type is established on the existence of solar radiance, without this the panels have little or no efficiency at all, so they are limited to sunny periods. One of the methods of increasing the impact and performance of these systems is the realization of hybrid systems that offer several benefits with regard to heating the air in rooms, heating water and ventilating spaces. The meaning of this article is to present a summary of the existing literature, in the sphere of solar hybrid air heating systems, on the methods of improvement and the performance achieved.
