AbstractSmall bowel malignancies are rare, though colorectal cancers are common. This article reviews the current imaging recommendations for small bowel and colorectal malignancies. Contrast-enhanced computed tomography (CT) is the imaging modality of choice for diagnosis/staging/response evaluation/follow-up of the small bowel and colonic tumors. Magnetic resonance imaging of the pelvis with high-resolution T2-weighted images in sagittal, oblique axial, and coronal planes is the imaging modality of choice for staging/response evaluation of anorectal tumors. CT colonography may be utilized as a tumor screening modality, alternative to colonoscopy.

AbstractCervical cancer is the fourth most common cancer in women globally and the second most common cancer in Indian women, more common in lower socioeconomic strata. Improvement in survival and decrease in morbidity reflect the earlier detection with screening and imaging, as well as multifactorial multimodality therapy integrating surgery, and concurrent chemoradiation therapy providing superior therapeutic benefits. Imaging plays a vital role in assessing the extent of disease and staging of cervical cancer. The appropriateness criteria of a modality are different from its availability based on infrastructure, medical facilities, and resource status. Although in an ideal situation, magnetic resonance imaging (MRI) would be of greatest value in locoregional assessment of extent of disease and fluorodeoxyglucose positron emission tomography-computed tomography for distant staging; often, an ultrasonography, chest radiograph, and bone scans are utilized, with contrast-enhanced computed tomography representing a fair superior diagnostic accuracy, and can be reported as per the RECIST 1.1 criteria. MRI is also of good utility in the assessment of residual disease, predicting response and detecting small volume recurrence. MRI offers the highest diagnostic accuracy in determining parametrial invasion and hence surgical planning; so also, MRI-guided radiation planning helps in more accurate graded radiation dose planning in radiation therapy. Stage and therapy-based surveillance imaging should be encouraged and recommended.

AbstractRenal cell carcinomas accounts for 2% of all the cancers globally. Most of the renal tumors are detected incidentally. Ultrasound remains the main screening modality to evaluate the renal masses. A multi -phase contrast enhanced computer tomography is must for characterizing the renal lesions. Imaging plays an important role in staging, treatment planning and follow up of renal cancers. In this review , we discuss the imaging guidelines for the management of renal tumors.
A bibliometric analysis of cultural heritage research in the humanities: The Web of Science as a tool of knowledge management
Authors: Vlase Ionela , Lähdesmäki Tuuli 
Published: March 2023

AbstractSubstantial research on the topic of cultural heritage has been conducted over the past two decades. At the same time, the overall output volume of journals and citation metrics have become important parameters in assessing and ranking researchers’ performance. Even though the scholarly interest in cultural heritage has recently increased world-wide, a comprehensive analysis of the publication output volume and its correlation to the shift in the cultural heritage regime starting in 2003 is still lacking. The article aims to understand the role of Web of Science (WOS) as a tool of knowledge management in academia by drawing on the scholarly output volume, the patterns displayed by this volume, and the intellectual structure of cultural heritage research based on WOS-indexed journal articles. The data include 1843 journal articles published between 2003 and 2022 and indexed in the WOS Core Collection. The article draws on a bibliometric analysis by using WOS tools and employing VOSviewer software to map and visualize hidden patterns of research collaboration and avenues of knowledge progress. The cultural heritage research indexed in WOS was found to be Eurocentric, corresponding to the increasing funding provided by European national and supranational agencies for research funding. Although the indexed research has grown significantly, the bulk of studies on cultural heritage in WOS is concentrated in a reduced number of European institutions and countries, written by a small number of prolific authors, with relatively poor collaborative ties emerging across time between authors, institutions, and countries. The central themes reflect the development of digital technologies and increased participatory emphasis in cultural heritage care. This article brings new insights into the analysis of the cultural heritage research in correlation with the emergence of international heritage governance with new institutional actors, professional networks, and international agreements, which are all constitutive elements of scientific production. The article seeks to critically assess and discuss the results and the role of WOS as a tool of knowledge management in academia.
Power relations are central to shaping collaborative governance of the urban sharing economy
Authors: Cao Jun , Prior Jason , Giurco Damien , Gu Dasong 
Published: March 2023

AbstractSince its rise in the early 2000s, the sharing economy has expanded and developed rapidly worldwide. While the sharing economy can boost resource-use efficiency and encourage sustainable urban living, it also challenges urban governance. Recently, a collaborative governance (CG) approach involving public and private partnerships has been adopted in various global cities to address these governance dilemmas. However, the influence of stakeholder power relations on the CG of the sharing economy remains inadequately explored in the literature. This article argues that multi-actor collaboration can be enhanced by clarifying how power relations shape effective governance, actor engagement, shared motivation, and capacity for joint actions. This article draws on practical insights by discussing examples of the governance practices of urban bike-sharing programs to demonstrate how the nature of public-private power relations can result in specific (and quite different) forms of CG. This article will help CG researchers, policymakers, urban planners, and communities understand CG practices in the new era of shared cities and global cities.

Published: March 2023

Piezoelectric acoustic emission sensors can be used detect the sound emitted by the target structure when it is damaged and have important applications in the field of structure health monitoring. However, due to the mismatch of the interface acoustic impedance, it is hard for the conventional ultrasonic sensor to monitor the acoustic emission in a pipe structure. In this work, a flexible sensor by the deposition of a Pb(Zr0.52,Ti0.48)O3 thin film on a mica substrate was fabricated, and the acoustic emission generated by the partial discharge of a 110 kV power cable was detected by using the flexible sensor. The flexible sensor was designed with an electromagnetic shielding structure and, therefore, can screen most of the electromagnetic interference. The flexible sensor shows a relatively flat response in the frequency range from 100 to 1000 kHz with a sensitivity over 47.5 dB, which is beneficial for pattern recognition studies of acoustic emission. This work not only provides a flexible, anti-electromagnetic interference and broadband sensor for acoustic emission detection but also promotes the development and application of flexible ferroelectric materials.
Analysis of sampling methods for imaging a periodic layer and its defects
Authors: Boukari Yosra , Haddar Houssem , Jenhani Nouha 
Published: March 2023

Abstract
We revisit the differential sampling method introduced in (Haddar and Nguyen 2017 Comput. Math. Appl.
74 2831–55) for the identification of a periodic domain and some local perturbation. We provide a theoretical justification of the method that avoids assuming that the local perturbation is also periodic. Our theoretical framework uses functional spaces with continuous dependence with respect to the Floquet–Bloch variable. The corner stone of the analysis is the justification of the generalized linear sampling method in this setting for a single Floquet–Bloch mode.
Innovations in nanosynthesis: emerging techniques for precision, scalability, and spatial control in reactions of organic molecules on solid surfaces
Authors: Lipton-Duffin Josh , MacLeod Jennifer 
Published: March 2023

Abstract
The surface science-based approach to synthesising new organic materials on surfaces has gained considerable attention in recent years, owing to its success in facilitating the formation of novel 0D, 1D and 2D architectures. The primary mechanism used to date has been the catalytic transformation of small organic molecules through substrate-enabled reactions. In this Topical Review, we provide an overview of alternate approaches to controlling molecular reactions on surfaces. These approaches include light, electron and ion-initiated reactions, electrospray ionisation deposition-based techniques, collisions of neutral atoms and molecules, and superhydrogenation. We focus on the opportunities afforded by these alternative approaches, in particular where they may offer advantages in terms of selectivity, spatial control or scalability.
25.7% efficient PERC solar cell using double side silicide on oxide electrostatically doped (SILO-ED) carrier selective contacts: process and device simulation study
Authors: Kashyap Savita , Pandey Rahul , Madan Jaya 
Published: March 2023

Abstract
Passivating contacts have recently considered as a superior carrier-selective contact approach for high-efficiency silicon-based photovoltaic devices. However, the conversion efficiencies of the silicon-based passivated emitter and rear cell (PERC) are limited by contact recombination losses that reduce their performance. Therefore, we investigated a new manufacturable silicide on oxide-based electrostatically doped (SILO-ED) carrier-selective contact to suppress the contact recombination losses and reduce the saturation current density (j
0). For the first time, double side electrostatic doping is introduced to the PERC devices to form the carrier selective passivating contacts. First, a conventional PERC device was designed and the effects of surface recombination velocity (SRV) at both contacts were studied. After that, single and double SILO-ED based contacts are introduced into the device and a systematic analysis is performed to understand the tunneling phenomena and improve the conversion efficiency compared to existing PERC cells. The front SILO-ED based device with back contact SRV of 10 cm s−1 showed a power conversion efficiency of 25.4% with j
0 (14.3 fA·cm−2). In contrast, the double SILO-ED device delivered 25.7% conversion efficiency by further suppressing the j
0 to 11.8 fA·cm−2 by implementing SILO-ED approach with two different metal silicides such as erbium silicide (ErSi2) and palladium silicide (Pd2Si) on front and rear contact surface. The champion double SILO-ED PERC solar cell delivered a conversion efficiency of 25.7% with an open circuit voltage (V
OC) of 742 mV. The results reported in this study would help to develop superior passivating contact-based PERC solar cells for higher efficiencies.
Self-sensing synchronized switch damping based on zero-crossing detection with voltage decay compensation
Authors: Zhang Lin , Li Ming , Deng Pengcheng , Cheng Wei 
Published: March 2023

Abstract
Synchronized switch damping (SSD) techniques have been developed for structural vibration suppression in recent years. In SSD control, a self-sensing approach can invert the voltage on piezoelectric materials at displacement extrema without sensors or real-time controllers. However, tracing extrema from the voltage on piezoelectric materials has become challenging since the voltage generated by the vibration of controlled mode is minor compared with noises as the increase of damping performance. Furthermore, the voltage decay caused by the current leakage is dominant when the host structure vibrates at a low frequency. This paper proposes a self-sensing approach based on the zero-crossing detection technique with voltage decay compensation. The switching delay and voltage decay are considered in the electromechanical model of the SSD system. Accordingly, a band-limited proportional-differential circuit is implemented to offset the voltage decay and generate zero-crossings at displacement extrema simultaneously. Experiments show that the proposed method is still effective when the voltage decay in the SSD control is dominant.
Experimental study on the critical pressure of converging ferrofluid seal with alternating pole teeth
Authors: Yang Xiaolong , Jiang Lei , Li Decai 
Published: March 2023

Abstract
For the improvement of pressure capability in ferrofluid seal with a small gap, a structure of converging ferrofluid seal (CFS) with alternating pole teeth is proposed in this study. Distribution of magnetic field in this structure is analyzed by using finite element method, and then theoretical values of withstanding gas pressure are calculated. The influence of ferrofluid volume, sizes of radial and axial sealing gap, numbers of radial and axial pole teeth on the critical pressure of CFS with alternating pole teeth is studied on the test bench. Then experimental results are compared and analyzed with the experimental pressure resistance of ordinary stepped ferrofluid seal. It is demonstrated that the calculated value of pressure resistance of the CFS with alternating pole teeth fits well with the experimental data. The volume of the injected ferrofluid can reach saturation. The sealing performance of CFS with alternating pole teeth is related not only to the clearance between pole teeth and stepped shaft, but also to the number of radial and axial pole teeth. The sealing performance of CFS with alternating pole teeth is better than that of ordinary stepped ferrofluid seal.

Halo-independent bounds on the non-relativistic effective theory of WIMP-nucleon scattering from direct detection and neutrino observations
Authors: Kang Sunghyun , Kar Arpan , Scopel Stefano 
Published: March 2023

Abstract
We combine experimental constraints from direct detection searches and from neutrino
telescopes looking for WIMP annihilations in the Sun to derive halo-independent bounds on each of
the 28 WIMP-proton and WIMP-neutron couplings of the effective non-relativistic Hamiltonian
that drives the scattering process off nuclei of a WIMP of spin 1/2. The method assumes that the
velocity distribution is normalized to one and homogeneous at the the solar system scale, as well
as equilibrium between WIMP capture and annihilation in the Sun, and requires to fix the WIMP
annihilation channels (we assume bb̅). We consider a single non-vanishing coupling at a
time, and find that for most of the couplings the degree of relaxation of the halo-independent
bounds compared to those obtained by assuming the Standard Halo Model is with few exceptions
relatively moderate in the low and high WIMP mass regimes, where it can be as small as a factor of
≃ 2, while in the intermediate mass range between 10 GeV and 200 GeV it can be as large as
∼ 103. An exception to this general pattern, with more moderate values of the bound
relaxation, is observed in the case of spin-dependent WIMP-proton couplings with no or a
comparatively small momentum suppression, for which WIMP capture is strongly enhanced because it
is driven by scattering events off 1H
, which is the most abundant target in the Sun. Within
this class of operators the relaxation is particularly small for interactions that are driven by
only the velocity-dependent term, for which the solar capture signal is enhanced compared to the
direct detection one, thanks to the highest speed of scattering WIMPs within the Sun due to the
larger gravitational acceleration.
Anatomy of single-field inflationary models for primordial black holes
Authors: Karam Alexandros , Koivunen Niko , Tomberg Eemeli , Vaskonen Ville , Veermäe Hardi 
Published: March 2023

Abstract
We construct an analytically solvable simplified model that captures the essential
features for primordial black hole (PBH) production in most models of single-field inflation. The
construction makes use of the Wands duality between the constant-roll (or slow-roll) and the
preceding ultra-slow-roll phases and can be realized by a simple inflaton potential of two joined
parabolas. Within this framework, it is possible to formulate explicit inflationary scenarios
consistent with the CMB observations and copious production of PBHs of arbitrary mass. We quantify
the variability of the shape of the peak in the curvature power spectrum in different inflationary
scenarios and discuss its implications for probing PBHs with scalar-induced gravitational wave
backgrounds. We find that the COBE/Firas μ-distortion constraints exclude the production of
PBHs heavier than 104
M
⊙ in single-field inflation.
Back to the features: assessing the discriminating power of future CMB missions on inflationary models
Authors: Braglia Matteo , Chen Xingang , Kumar Hazra Dhiraj , Pinol Lucas 
Published: March 2023

Abstract
Future Cosmic Microwave Background (CMB) experiments will deliver extremely accurate measurements of the E-modes pattern of the CMB polarization field.
Given the sharpness of the E-modes transfer functions, such surveys make for a powerful detector of high-frequency signals from primordial features that may be lurking in current data sets.
With a handful of toy models that increase the fit to the latest Planck data, but are of marginal statistical significance, we use a state-of-the-art forecast pipeline to illustrate the promising prospects to test primordial features in the next decade.
Not only will future experiments allow us to detect such features in data, but they will also be able to discriminate between models and narrow down the physical mechanism originating them with high statistical significance.
On the other hand, if the anomalies in the currently measured CMB spectra are just statistical fluctuations, all the current feature best fit candidates will be ruled out. Either way, our results show that primordial features are a clear target of forthcoming CMB surveys beyond the detection of tensor modes.
Nova neutrinos in the multi-messenger era
Authors: Guetta Dafne , Hillman Yael , Della Valle Massimo 
Published: March 2023

Abstract
The recently discovered high energy emission from the recurrent nova RS Ophiuchi by Fermi-LAT (> 100 MeV), H.E.S.S. and MAGIC (>100 GeV), hints towards a possible hadronic origin of this radiation component.
From the observed high energy photon flux we derive the expected number of neutrino events that could be detected by present and future neutrino telescopes in the different energy ranges.
Preliminary estimates indicate that with the “next-generation” instrument IceCube-Gen2, the expected number of neutrino detections from Galactic novae, admittedly with large uncertainty, should not exceed 1 event per decade.
The impact of inlet mach number and domain shape on subsonic nozzle flow via small disturbance equation
Authors: Qian Xuehui 
Published: March 2023

Abstract
Computational fluid dynamics (CFD) is a cross-disciplinary field that combines mathematics, fluid dynamics, and computer programming to simulate and analyze fluid flow problems using numerical methods. Nowadays, the use of CFD to conduct numerical simulations rather than costly and time-consuming ignition experiments has become an essential aspect of nozzle design. Therefore, it is significant to study the nozzle by numerical simulation. In this paper, a numerical method called small disturbance equation (SDE) is adopted to investigate the impact of inlet Mach number and domain shape on subsonic nozzle flow. Conducting the small disturbance equation via python code, the impact of the inlet Mach number and domain shape is revealed by comparing the different errors of the method, streamlines of the nozzle flow, velocity fields. It is found that with the increase of inlet Mach number, the error of the SDE method grows, and the velocity in x-direction increases while the velocity in y-direction stays the same. Besides, with the shrink of the domain shape, the error of the SDE method gets larger, meanwhile, the maximum of the velocity in each direction increases while the minimum of the velocity decreases. This research would make advantages to identify the optimal designs of a subsonic nozzle.

Published: March 2023

Abstract
To study the effect of a constant-pressure rear-spray low recoil weapon with two chambers on weapon launch performance, based on two-phase flow theory, the valve-spring type constant-pressure rear-spray low recoil weapon firing process with two chambers was studied numerically. Considering the movement of the valve-spring system, a mathematical model of the weapon launch process combining the two-phase flow of gas and solid in the front and back chambers, the movement of the projectile and the transient flow of gas in the lateral rear nozzle is established. Using a 30 mm chain gun as an example, numerical simulation was carried out, and the distribution law of the flow field in the two chambers and the lateral rear nozzle during the firing of the weapon was obtained and compared with the internal flow field of the traditional weapon chamber. The results show that by reasonably matching parameters to control the flow of gunpowder gas in the two chambers, the recoil impulse can be reduced by 81.58% under the premise that the initial velocity of the projectile does not decrease, and the purpose of making full use of gunpowder gas energy to greatly reduce arms recoil is realized.
