Published: November 2022

Abstract
Single-crystalline Mg-implanted Si layers are synthesized by ion implantation followed by pulsed laser melting. The Mg doping concentration is reaching 1021 cm−3. The Raman, Rutherford backscattering spectrometry/channeling and particle induced x-ray emission measurements confirm the recrystallization of the Mg-implanted Si layer. A strong below band gap infrared absorption over the wavelength range of 1.4–6.2 µm (0.2–0.87 eV, in the mid-infrared range) has been observed in the Mg-implanted Si layers. It is associated with deep levels induced by Mg atoms at high implantation level. This work points out the potential of Mg-implanted Si for room-temperature light detection in a broad infrared range for the new generation of Si-based photonics.

Published: November 2022

Abstract
Due to the continuous downsizing of metal oxide semi-conductor field effect transistor devices, power dissipation is one of the vital issues for the integrated circuit design. As a result of voltage scaling at lower technology nodes, threshold voltage decreases which results in increase in leakage current, hence leads to increase in leakage power dissipation. In this paper, a novel low leakage technique called LCINDEP (leakage control input DEPendent) is proposed for nano-scaled circuits. The device characteristics and hence overall performance gets affected due to increased power dissipation. Proposed LCINDEP technique is extensively demonstrated for low power operation and reliability analysis. Various short gate (SG) fin type field effect transistor (FinFET) logic circuits are simulated using LCINDEP technique and comparative analysis is performed with the already available leakage reduction techniques. The proposed LCINDEP technique provides reduced leakage power by 89.71% and 91.92% in LCINDEP SG FinFET NAND and NOR gates respectively with respect to the conventional SG FinFET NAND and NOR gates. Besides this benchmark circuits like ring oscillator and ISCAS-85 C17 show decrease in power dissipation by 24.75% and 35.5% respectively with LCINDEP technique in respect to the conventional FinFET circuits. Reliability analysis in terms of process voltage and temperature variations is performed using Monte Carlo Approach for 5000 samples, which also depicts that proposed LCINDEP technique is more reliable than the available low power techniques. The normalized standard deviations (σ/µ)% is improved by 54.68% and 43.93% for power delay product metric in the proposed technique compared to the conventional one for SG FinFET NAND and NOR gates respectively. All the simulations are performed at 16 nm technology node for FinFET logic devices using predictive technology model multigate based on BSIM-CMG on HSPICE tool.

Abstract
It is challenging to equip a soft manipulator with sensors without compromising its mechanical properties. In this paper, we explain the design, analysis, and building of an innovative, low-cost soft parallel manipulator with sensing and actuation capabilities. Innovative bubble artificial muscle actuators serve as the connecting rod and contraction type actuator for the manipulator, as well as an opto-mechanical tactile sensor (TacTip) for objects detection. We propose a simulation method for the key structural design parameters of TacTip, and the influence of TacTip’s pin height, pin diameter, and surrounding pin angle on perceptual sensing has been examined via testing, which can provide a design guideline for the TacTip’s the structure. The impact of the counterweight on the soft parallel manipulator end-ascending effector’s and descending velocity, as well as its vertical and horizontal workspace, has been the topic of dynamic tests using a range of counterweights. The soft parallel manipulator’s workspace has been analyzed. In addition, an innovative, cost-effective, and simple soft-smart parallel robotic manipulator (PSM) control system has been built, and a demonstration of the detection and movement of the soft parallel manipulator is shown. The results demonstrate that the soft parallel manipulator described in this research is capable of detecting motion and collisions. It is anticipated that this soft-smart PSM would expand the employment of optical tactile sensors and artificial muscle actuators in material handling and size/shape sorting assembly lines.

Published: November 2022

AbstractWe provide an accurate comparison, against large cosmologicalN-body simulations, of different prescriptions for modelling nonlinear matter power spectra in the presence of massive neutrinos and dynamical dark energy. We test the current most widely used approaches: fitting functions (HALOFIT and HMcode), the halo-model reaction (ReACT) and emulators (baccoemuand EuclidEmulator2). Focussing on redshiftsz≤ 2 and scalesk≲ 1h/Mpc (where the simulation mass resolution provides ∼ 1% accuracy), we find that HMcode andReACTconsiderably improve over the HALOFIT prescriptions of Smith and Takahashi (both combined with the Bird correction), with an overall agreement of 2% for all the cosmological scenarios considered. Concerning emulators, we find that, especially at low redshifts, EuclidEmulator2 remarkably agrees with the simulated spectra at ≲ 1% level in scenarios with dynamical dark energy and massless neutrinos, reaching a maximum difference of ∼ 2% atz= 2.baccoemuhas a similar behaviour as EuclidEmulator2, except for a couple of dark energy models. In cosmologies with massive neutrinos, atz= 0 all the nonlinear prescriptions improve their agreement with respect to the massless neutrino case, except for the Bird and TakaBird models which, however, are not tailored tow0–wamodels. Atz> 0 we do not find a similar improvement when including massive neutrinos, probably due to the lower impact of neutrino free-streaming at higher redshifts; rather atz= 2 EuclidEmulator2 exceeds 2% agreement for some dark energy equation of state. When considering ratios between the matter power spectrum computed in a given cosmological model and its ΛCDM counterpart, all the tested prescriptions agree with simulated data, at sub-percent or percent level, depending onz. Finally, we also test how nonlinear prescriptions compare against simulations when computing cosmic shear and angular galaxy clustering spectra. For the former, we find a 2–3% agreement for HMcode,baccoemu, EuclidEmulator2 andReACT; for the latter, due to the minimum stellar mass of the simulated galaxies, shot noise highly affects the signal and makes the discrepancies as high as 5%.

Abstract
In this paper, we use a Tsallis holographic dark energy model in two forms, interacting and non-interacting cases, to acquire some parameters as the equation of state for the energy density of the Tsallis model in the FRW Universe concerning the complex form of quintessence model. We will study the cosmology of complex quintessence by revamping the potential and investigating the scalar field dynamics. Then we analyze (

Published: November 2022

Abstract
We present the estimation of solar observation with the Five-hundred-meter Aperture Spherical radio Telescope (FAST). For both the quiet Sun and the Sun with radio bursts, when pointing directly to the Sun, the total power received by FAST would be out of the safe operational range of the signal chain, even resulting in damage to the receiver. As a conclusion, the Sun should be kept at least ∼2° away from the main beam during observations at ∼1.25 GHz. The separation for lower frequency should be larger. For simplicity, the angular separation between the FAST beam and the Sun is suggested to be ∼5° for observations at 200 MHz or higher bands.

Abstract
The Cryogenic Underground Observatory for Rare Events
(CUORE) is the most sensitive experiment searching for neutrinoless
double-beta decay (0νββ) in 130Te. CUORE
uses a cryogenic array of 988 TeO2 calorimeters operated at
∼10 mK with a total mass of 741 kg. To further increase the
sensitivity, the detector response must be well understood. Here, we
present a non-linear thermal model for the CUORE experiment on a
detector-by-detector basis. We have examined both equilibrium and
dynamic electro-thermal models of detectors by numerically fitting
non-linear differential equations to the detector data of a subset
of CUORE channels which are well characterized and representative of
all channels. We demonstrate that the hot-electron effect and
electric-field dependence of resistance in NTD-Ge thermistors alone
are inadequate to describe our detectors' energy-dependent pulse
shapes. We introduce an empirical second-order correction factor in
the exponential temperature dependence of the thermistor, which
produces excellent agreement with energy-dependent pulse shape data
up to 6 MeV. We also present a noise analysis using the fitted
thermal parameters and show that the intrinsic thermal noise is
negligible compared to the observed noise for our detectors.
3D biodegradable shape changing composite scaffold with programmable porous structures for bone engineering

Published: November 2022

Abstract
This study developed a biodegradable composite porous polyurethane scaffold based on polycaprolactone and polyethylene glycol by sequential in-situ foaming salt leaching and freeze-drying process with responsive shape changing performance. Biomineral hydroxyapatite (HA) was introduced into the polyurethane matrix as inorganic fillers. Infrared spectroscopy results proved a successful synthesis, scanning electron microscopy showed that the scaffold’s porosity decreased with the addition of HA while the average pore size increased. X-ray diffraction and differential scanning calorimetry showed that the addition of HA lowered the melting point of the scaffold, resulting in a transition temperature close to the human body temperature. From the bending experiments, it could be demonstrated that PUHA20 has excellent shape memory performance with shape fixity ratio >98.9% and shape recovery ratio >96.2%. Interestingly, the shape-changing capacity could be influenced by the porous structures with variation of HA content. The shape recovery speed was further accelerated when the material was immersed in phosphate buffered saline at 37 °C. Additionally, in vitro mineralization experiments showed that the scaffold incorporating HA had good osteoconductivity, and implantation assessment proved that scaffolds had good in vivo biocompatibility. This scaffold is a promising candidate for implantation of bone defects.
Insight into synergetic effects of serum albumin and glucose on the biodegradation behavior of WE43 alloy in simulated body fluid
Authors: Imani Amin , Clifford Amanda M , Raman R K Singh , Asselin Edouard 
Published: November 2022

Abstract
The biodegradation rate of Mg alloy medical devices, such as screws and plates for temporary bone fracture fixation or coronary angioplasty stents, is an increasingly important area of study. In vitro models of the corrosion behavior of these devices use revised simulated body fluid (m-SBF) based on a healthy individual’s blood chemistry. Therefore, model outputs have limited application to patients with altered blood plasma glucose or protein concentrations. This work studies the biodegradation behavior of Mg alloy WE43 in m-SBF modified with varying concentrations of glucose and bovine serum albumin (BSA) to (1) mimic a range of disease states and (2) determine the contributions of each biomolecule to corrosion. Measurements include the Mg ion release rate, electrolyte pH, the extent of hydrogen evolution (as a proxy for corrosion rate), surface morphology, and corrosion product composition and effects. BSA (0.1 g l–1) suppresses the rate of hydrogen evolution (about 30%) after 24 h and—to a lesser degree—Mg2+ release in both the presence and absence of glucose. This effect gets more pronounced with time, possibly due to BSA adsorption on the Mg surface. Electrochemical studies confirm that adding glucose (2 g l–1) to the solution containing BSA (0.1 g l–1) caused a decrease in corrosion resistance (by around 40%), and concomitant increase in the hydrogen evolution rate (from 10.32 to 11.04 mg cm–2 d–1) to levels far beyond the tolerance limits of live tissues.
Observational evidence of intensified nocturnal urban heat island during heatwaves in European cities
Authors: Possega Marco , Aragão Leonardo , Ruggieri Paolo , Santo Marco Antonio , Di Sabatino Silvana 
Published: November 2022

Abstract
A heatwave (HW) is a large-scale meteorological event characterised by persistent and extremely high-temperature condition. At the local scale, the urban heat island (UHI) is another thermal-related phenomenon defined as an urban area warmer than its surrounding regions due to different surfaces’ capabilities to absorb and store heat. However, the assessment about the effect produced on UHI by HW events is not homogeneous. Indeed, regarding the capability of HWs to influence the urban-rural temperature difference, several studies report different conclusions describing both an exacerbation and a reduction of UHI during HW events. In this context, the present study analyses in situ long records of temperature measurements (20 years) to provide observational shreds of evidence of UHI modification under HW conditions. We examine data from the European Climate Assessment & Dataset and World Meteorological Organization computing the UHI index (UHII) to quantify the UHI effect intensity in 37 European cities during the last 20 summers. The results show an UHII intensification for 28 of the 32 cities affected by positive UHI during extremely high temperatures at night, while substantial variations are not observed during the daytime. The time evolution of UHI during a HW highlights that a more significant and persistent urban-rural temperature gradient explains the UHI intensification. Finally, the relationship between the large and local-scale temperature phenomena reveals that continental high-temperature periods are often associated with prominent temperature differences between small-scale urban and rural environments, assessing the impact of large-scale features on thermal stress at the local scale.
Quantum dynamics in a single excitation subspace: deviations from eigenstate thermalization via long time correlations
Authors: Nation Charlie , Porras Diego 
Published: November 2022

Abstract
In this work we study a scenario where unitary quantum dynamics in a many-body interacting system is restricted to a single excitation subspace. We ask how dynamics within to such a subspace may in general differ from predictions of the eigenstate thermalization hypothesis (ETH). We show that for certain initial states and observables, if thermalization occurs, it will not fulfil other key predictions of the ETH; instead following differing generic behaviours. We show this by analysing long-time fluctuations, two-point correlation functions, and the out-of-time-ordered correlator; analytically detailing deviation from ETH predictions. We derive instead an ETH-like relation, with non-random off-diagonals for matrix elements of observables, with correlations which alter long-time behaviour and constrain dynamics. Further, we analytically compute the time-dependence of the decay to equilibrium, showing it is proportional to the survival probability of the initial state. We finally note the conditions studied are common in many physical scenarios, such as under the rotating-wave approximation. We show numerically our predictions are robust to perturbations which break this approximation.
On the interoperability of Building Information Modeling for Energy Analysis: the case study of the Maritime Station of Napoli (Italy)

Published: November 2022

Abstract
This paper experiences the potential of the use of Building Information Modeling (BIM) technique as a strategy to facilitate the energy performance analysis of existing buildings with historical relevance. The relationship between BIM and sustainability is an emerging concept which is becoming more and more interesting in the construction industry. The different methods for energy modeling of buildings provided in the literature usually imply the use of dynamic simulation software, such as EnergyPlus and TRNSYS, whose graphical interfaces are essential and not particularly user-friendly, if compared to the more popular CAD. Modelling in BIM environment, on one hand, helps to speed up certification procedures and, on the other hand, to define a new work philosophy during the design of energy efficiency interventions, thanks to the software’s interoperability. This study focuses on the analysis of the energy performance of the Maritime Station of Napoli, in southern Italy, located in the Angevin wharf and hosting the port terminal. The procedure employed for the study is a BIM working procedure, therefore involving different software tools. The authors have analyzed and compared the results obtained with different tools, to verify the efficiency of their interoperability, together with the parameters that most influence the analysis. Finally, the authors evaluate the dependency of the results from climatic conditions, conducting the analysis for other two Italian cities, located in different Italian climatic zones.
Proposal and validation of a new innovative solution for green hydrogen storage, via clathrate hydrates.
Authors: Gambelli AM , Rossi F 
Published: November 2022

Abstract
According to the European Green Deal, the production of green hydrogen is gaining the growing interest of scientists and industrialists. The European Strategy for Hydrogen denotes it as one of the main contributors to achieve the carbon neutrality of Europe within 2050. In this context, the whole chain of hydrogen must be defined with accuracy: from the raw energy needed for its production, to the following crucial phases, like storage and transportation. This article aims to propose an innovative solution to store hydrogen at competitive conditions. According to it, H2 molecules are enclathrated in solid crystalline water structures and form gas hydrates. Prior than this phase, it is mixed with carbon dioxide and/or small chain hydrocarbons, in order to lower the pressures required for the process. The final product will show high energy density, safety for humans (non-toxicity and lower flammability and explosivity, compared to the known techniques), easy of transportation. Moreover, it will assume a highly competitive energy stored/energy spent ratio. Finally, being the gas molecules only physically trapped into water cages, the following separation of hydrogen from the aid gases, also due to the different sizes between them, can be easily obtained at competitive costs.
