Context. The detections of narrow channels of accretion toward protostellar disks, known as streamers, have increased in number in the last few years. However, it is unclear whether streamers are a common feature around protostars that were previously missed, or if they are a rare phenomenon.Aims. Our goals are to obtain the incidence of streamers toward a region of clustered star formation and to trace the origins of their gas to determine whether they originate within the filamentary structure of molecular clouds or from beyond.Methods. We used combined observations of the nearby NGC 1333 star-forming region, carried out with the NOEMA interferometer and the IRAM 30m single dish. Our observations cover the area between the systems IRAS 4 and SVS 13. We traced the chemically fresh gas within NGC 1333 with HC3N molecular gas emission and the structure of the fibers in this region with N2H+emission. We fit multiple velocity components in both maps and used clustering algorithms to recover velocity-coherent structures.Results. We find streamer candidates toward 7 out of 16 young stellar objects within our field of view. This represents an incidence of approximately 40% of young stellar objects with streamer candidates in a clustered star-forming region. The incidence increases to about 60% when we only considered embedded protostars. All streamers are found in HC3N emission.Conclusions. Given the different velocities between HC3N and N2H+emission, and because by construction, N2H+traces the fiber structure, we suggest that the gas that forms the streamers comes from outside the fibers. This implies that streamers can connect cloud material that falls onto the filaments with protostellar disk scales.

Published: April 2024

AbstractDepression is a mood disorder associated with cognitive decline. To
self-medicate, people use medicinal herbs to limit the side effects associated
with taking antidepressants, such as addiction, hallucinations, and dizziness.
Current research consists of ethnobotanical studies of medicinal plants used to
improve depression-related mood disorders, and the socio-economic profiles of
people with depression (gender, age, education level…) and information about the
listed antidepressant plants (common name, part used…). 129 individuals
belonging to some regions of Algeria answered our questionnaire among which 82%
are women and 98% are academics. The informants cited 44 species (Mentha
spicata with a relative frequency of citation (RFC) =0.69, Chamomilla
nobilis RFC=0.49, Aloysia citrodora RFC=0.19, Lavandula
officinalis, Melissa officinalis RFC=0.17, Foeniculum
vulgare RFC=0.1, Pimpinella anisum RFC=0.09 and Hypericum
perforatum RFC=0.07…) belonging to 25 botanical families represented
mainly by the Lamiaceae family (38%). Infusion remains the most common method of
preparation, and the leaves are the most used part. These plants modulated the
depressive state of informants in a similar way to synthetic antidepressants.
These plants deserve to be studied for the development of new herbal drugs with
acceptable side effects.
Quantitative ultrasound radiomics analysis to evaluate lymph nodes in patients with cancer: a systematic review
Authors: Guerrisi Antonio , Miseo Ludovica , Falcone Italia , Messina Claudia , Ungania Sara , Elia Fulvia , Desiderio Flora , Valenti Fabio , Cantisani Vito , Soriani Antonella , Caterino Mauro 
Published: April 2024

AbstractThis systematic review aims to evaluate the role of ultrasound (US) radiomics in assessing
lymphadenopathy in patients with cancer and the ability of radiomics to predict metastatic
lymph node involvement. A systematic literature search was performed in the PubMed (MEDLINE),
Cochrane Central Register of Controlled Trials (CENTRAL), and EMBASE (Ovid) databases up to
June 13, 2023. 42 articles were included in which the lymph node mass was assessed with a US
exam, and the analysis was performed using radiomics methods. From the survey of the selected
articles, experimental evidence suggests that radiomics features extracted from US images can
be a useful tool for predicting and characterizing lymphadenopathy in patients with breast,
head and neck, and cervical cancer. This noninvasive and effective method allows the
extraction of important information beyond mere morphological characteristics, extracting
features that may be related to lymph node involvement. Future studies are needed to
investigate the role of US-radiomics in other types of cancers, such as melanoma.
Challenges and Strategies in Colorectal Surgery among Patients with Morbid Obesity
Authors: Dualeh Shukri H.A. , Howard Ryan 
Published: April 2024

AbstractThis chapter explores the interplay between morbid obesity and the challenges encountered in colorectal surgery. Understanding the unique considerations in preoperative and intraoperative management along with weight optimization tools such as bariatric surgery emerges as potential mitigators, demonstrating benefits in reducing colorectal cancer risk and improving perioperative outcomes. Furthermore, the pervasive stigma associated with morbid obesity further complicates patient care, emphasizing the need for empathetic and nuanced approaches. Recommendations for minimizing stigma involve recognizing obesity as a medical diagnosis, fostering respectful communication, and actively dispelling misconceptions. Colorectal surgeons are pivotal in navigating these complexities, ensuring comprehensive and tailored care for patients with morbid obesity.

Authors: Li Wai Ip , Ng Koon Kiu , Au Yong Ting Kun , Kung Boom Ting 
Published: April 2024

AbstractPhyllodes tumor is a rare fibroepithelial neoplasm of the breast. This tumor tends to spread by hematogenous route, with common metastatic sites in the lungs, bones, and liver. Metastases to the pleura, stomach, pancreas, kidneys, and adrenal gland are rare. We present a case of a 52-year-old lady with malignant phyllodes tumor of breast undergone local tumor resection, followed by solitary lung metastasis with lobectomy, and subsequently diagnosed of multiple new metastatic sites in pleura, stomach, pancreas, kidneys, adrenal gland, and bone detected on 2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography/computed tomography within 2 years.
An attempt to plot the source languages of village names on a map of Kachin State, Myanmar
Authors: Sawada Hideo 
Published: April 2024

Abstract
The Kachin State of Myanmar is home to a variety of ethnic groups, including Kachin, Tai, and Burmese. This is a result of the ethnic migrations and expansions that have occurred in the area. Determining the source language of a village name and plotting it on a map could provide clues to the present and past distribution of the ethnic groups, and also supporting evidence for presumed ethnic migrations and expansions. In this paper, I will outline methods for determining the source languages of village names in Kachin State based on the resources such as descriptions on maps, information gathered through interviews, names of families and clans and so on. I will also present the results of an attempt to plot the source languages on a map at the current stage.
Latin <XS>: Seeing double
Authors: Senesi Rosso Manuel 
Published: April 2024

Abstract
We can observe a systematic reorganization of the Latin Spelling System in the II and I centuries BC. We will
focus on the etiology and diffusion of <XS> spelling for the /ks/ cluster instead of <X>, highlighting the interplay
between centripetal and centrifugal forces in the standardization process. Its etiology and further diffusion will be compared to
the emergence of other spelling innovations in the Latin writing system of the second century BC. We will propose that the
progressive integration of <XS> spelling in the systematic orthography of Latin was favored by both morpho-graphemic and
phono-graphemic factors. Moreover, we will take into consideration the complex social network of the Roman Republic to trace back
<XS> diffusion path. We will propose that, alongside the leading role of the urban elites in its diffusion, also local
communities independently developed such a spelling variant, probably as a consequence of Greek systematic orthography’s
influence.
The standardisation of spelling in Middle English
Authors: Cahill Lynne 
Published: April 2024

Abstract
The standardisation of English spelling is widely assumed to have happened, or at least started, during the fifteenth century, with a variety of theories about the location and spread of the process. This paper provides an in-depth analysis of a single spelling feature: the vowel in the word said. It demonstrates that there were four main variants used across the country during the fifteenth and early sixteenth century, with preference for the modern standard form 〈ai〉 in Cambridgeshire, Middlesex and the Northern counties but for 〈ei〉 elsewhere. The analysis further raises serious questions about the claim that standardisation of the spelling system was well underway by the end of the fifteenth century, clearly showing that there was no reduction in either intra- or inter-document variation during the period covered by the MELD corpus, 1399–1525.
The experiences and needs of dog-‘owners’ affected by dog-theft
Authors: Venaktramanan Akaanksha , Roberts Lindsey 
Published: April 2024

Abstract
Objectives: Pet ‘ownership’ is empirically evidenced to improve mental and physical health, with research suggesting an anthropomorphic bond between ‘owners’ and dogs that equal familial relationships, including children. However, bereavement of dogs, and especially dog-theft, garner scarce interest, leaving a huge population to suffer disenfranchised grief unsupported. This study aims to validate the overlap of emotional value in familial and ‘owner’-dog relationships, and grief between dog-theft victims and those with missing loved ones. The study explores the needs of guardians suffering ambiguous loss, how they cope with it, and the role of social media in this process, to grow existing literature on the topic and guide psychological support resources. Design: Qualitative semi-structured interviews were conducted, and secondary data was collected from participants’ Facebook and Instagram posts. Methods: Four primary caregivers for their dog who had experienced dog-theft were recruited through social media. Hour-long interviews were conducted over Teams and social media posts were collated post informed consent. Audio recordings were transcribed, and primary and secondary data were separately analysed through a critical-realist onto-epistemological approach, using reflexive thematic analysis. Results: Five superordinate themes from primary data, and two from secondary were extracted that evidenced an anthropomorphic relationship and associated intensity of grief among victims of dog-theft. Correlations were found between grief and coping with missing loved ones and dogs, and additionally feelings of disenfranchisement. Social media is reported as safe and popular for expressing and processing complex emotions. Conclusions: Dog-theft is traumatic for guardians and causes suffering without knowledgeable support. Psychological research should aim to inform best-practice resources providing suitable help managing grief, social disenfranchisement, and other psychological or physiological consequences of this trauma.
Enhance the detection of surface micro/nanostructures by SPPs generated from silver film covered hemi-microsphere
Authors: Ren Wenyue , Huang Zhuozhuo , Wen Yangdong , Li Wen Jung 
Published: April 2024

Abstract
Surface plasmon polaritons (SPPs) are widely used for surface micro/nanostructures detection. However, because of the limitations of the common SPPs excitation conditions, it is difficult to flexibly detect surface micro/nanostructures in the air without being limited by the substrate structure. In this paper, a new SPPs excitation structure is developed. This structure is a silver film covered hemi-microsphere. SPPs could be excited on the surface of the Ag film, and induce collective oscillations of free electrons on the substrate surface to generate periodic electromagnetic waves. The periodic electromagnetic waves can enhance the electromagnetic field around the surface micro/nanostructures, which could benefit the detection of those surface micro/nanostructures. This method could work in the air, and requires less of the sample structure, but also could move above the sample to achieve a large range of detection. Simulation experiment results demonstrate that this structure has a good detection effect. The maximum enhancement achieved for nanoparticles is 113-fold. This structure holds great potential for medical detection and biosensing.
Cluster-based multidimensional scaling embedding tool for data visualization
Authors: Hernández-León Patricia , Caro Miguel A 
Published: April 2024

Abstract
We present a new technique for visualizing high-dimensional data called cluster MDS (cl-MDS), which addresses a common difficulty of dimensionality reduction methods: preserving both local and global structures of the original sample in a single 2-dimensional visualization. Its algorithm combines the well-known multidimensional scaling (MDS) tool with the k-medoids data clustering technique, and enables hierarchical embedding, sparsification and estimation of 2-dimensional coordinates for additional points. While cl-MDS is a generally applicable tool, we also include specific recipes for atomic structure applications. We apply this method to non-linear data of increasing complexity where different layers of locality are relevant, showing a clear improvement in their retrieval and visualization quality.
On the entropy corrected thermal features of black holes
Authors: Shababi Homa , Bandyopadhyay Tanwi , Debnath Ujjal 
Published: April 2024

Abstract
In this work, we investigate the thermal properties of black holes using a new class of generalized entropy functions [K Ourabah, Class. Quantum Grav., 41, 015 010 (2024)]. At the fundamental level, these entropic forms are associated with alternative gravitational laws, within an entropic gravity framework. Our investigation revolves around three distinct entropy functions associated with the Yukawa Potential Correction, Non-local Gravity Correction, and Gradient Field Gravity Correction. Through comparative analysis, we study how such entropic constructs impact the thermodynamic behavior of black holes. For each case, we derive the stability thermodynamic conditions associated with the respective entropic constructs.

Authors: Sharma Preeti , Tiwari Rakesh N , Singh Prabhakar 
Published: April 2024

Abstract
This paper investigates a small size 2 × 2 wideband multiple input multiple output (MIMO) antenna covering frequency band of 2.61 to 5.52 GHz. The antenna structure consists of elliptical ring patch with multiple circumferential slots. The edge-to-edge separation between the patches are kept 3.6 mm with volumetric dimensions of 30 × 46 × 1.6 mm3. The narrow slits are etched in the tapered ground plane to obtain the wideband characteristics. The electromagnetic coupling is improved more than 16 dB by employing the neutralization technique. The measured average gain and radiation efficiency of the proposed antenna are above 2.61dBi and 83.54%, respectively across the operating band. In addition to that, the important MIMO diversity parameters are investigated. The group delay and signal analysis in different orientations are also studied to ensure the quality performance of the antenna. The proposed MIMO antenna is simulated using CST microwave studio and further validated with the measurements. In addition to that, the parallel and orthogonal configuration of 4 × 4 MIMO antennas are analyzed by extending the proposed 2 × 2 MIMO design. The 4-port MIMO antennas exhibit the operating frequency bands varying from 2.80 to 5.58 GHz and 3.4 to 5.52 GHz, respectively for parallel and orthogonal MIMO configurations. The diversity parameters of 4-port MIMO antennas are calculated and compared with the measured results to verify its practical applications. Finaly, the SAR analysis of the antenna is presented at 3.08 and 5.20 GHz for 1/10 g tissues and are found 0.111/0.106 and 0.079/0.063 W K−1g−1, respectively. The proposed MIMO antenna designs are suitable for modern high-speed communication for 5G and sub-6 GHz frequency bands.

Abstract
A cross section evaluation of neutron induced reactions on 48Ti is undertaken using the Unified Monte Carlo-B (UMC-B) approach. The evaluation concentrates on estimating the covariance and the use of the UMC-B allows avoiding the deficiencies of linear regression brought by the traditional least squares method. Eight main neutron and charged particle emission reactions from n+48Ti in the fast neutron energy region below 20 MeV are studied in this work. The posterior probability density function (PDF) of each neutron cross section is obtained in a UMC-B Bayesian approach by convoluting the model PDFs sampled based on model parameters and the likelihood functions for the experimental data. Nineteen model parameters including level density, pair corrections, optical model and Kalbach matrix element parameter are stochastically sampled with the assumption of normal distributions to estimate the model uncertainty. The Cholesky factorization approach is applied to consider potential parameter correlations. Finally, the posterior covariance matrices are generated using the UMC-B generated weights. The new evaluated results are compared with the CENDL-3.2, ENDF/B-VIII.0, JEFF-3.3, TENDL-2021 and JENDL-5 evaluations and differences are discussed.

Abstract
The detrimental effect of imprint, which can cause misreading problem, has hindered the application of ferroelectric HfO2. In this work, we present results of a comprehensive reliability evaluation of Hf0.5Zr0.5O2-based ferroelectric random access memory. The influence of imprint on the retention and endurance is demonstrated. Furthermore, a solution in circuity is proposed to effectively solve the misreading problem caused by imprint.
Effect of annealing on the electrical performance of N-polarity GaN Schottky barrier diodes

Published: April 2024

Abstract
A nitrogen-polarity (N-polarity) GaN-based high electron mobility transistor (HEMT) shows great potential for high-frequency solid-state power amplifier applications because its two-dimensional electron gas (2DEG) density and mobility are minimally affected by device scaling. However, the Schottky barrier height (SBH) of N-polarity GaN is low. This leads to a large gate leakage in N-polarity GaN-based HEMTs. In this work, we investigate the effect of annealing on the electrical characteristics of N-polarity GaN-based Schottky barrier diodes (SBDs) with Ni/Au electrodes. Our results show that the annealing time and temperature have a large influence on the electrical properties of N-polarity GaN SBDs. Compared to the N-polarity SBD without annealing, the SBH and rectification ratio at ±5 V of the SBD are increased from 0.51 eV and 30 to 0.77 eV and 7700, respectively, and the ideal factor of the SBD is decreased from 1.66 to 1.54 after an optimized annealing process. Our analysis results suggest that the improvement of the electrical properties of SBDs after annealing is mainly due to the reduction of the interface state density between Schottky contact metals and N-polarity GaN and the increase of barrier height for the electron emission from the trap state at low reverse bias.

Published: April 2024

Abstract
High-speed solar-blind short wavelength ultraviolet radiation detectors based on κ(ε)-Ga2O3 layers with Pt contacts were demonstrated and their properties were studied in detail. The κ(ε)-Ga2O3 layers were deposited by the halide vapor phase epitaxy on patterned GaN templates with sapphire substrates. The spectral dependencies of the photoelectric properties of structures were analyzed in the wavelength interval 200–370 nm. The maximum photo to dark current ratio, responsivity, detectivity and external quantum efficiency of structures were determined as: 180.86 arb. un., 3.57 A/W, 1.78 × 1012 Hz0.5∙cm∙W−1 and 2193.6%, respectively, at a wavelength of 200 nm and an applied voltage of 1 V. The enhancement of the photoresponse was caused by the decrease in the Schottky barrier at the Pt/κ(ε)−Ga2O3 interface under ultraviolet exposure. The detectors demonstrated could functionalize in self-powered mode due to built-in electric field at the Pt/κ(ε)-Ga2O3 interface. The responsivity and external quantum efficiency of the structures at a wavelength of 254 nm and zero applied voltage were 0.9 mA/W and 0.46%, respectively. The rise and decay times in self-powered mode did not exceed 100 ms.
The influence of spheroid maturity on fusion dynamics and micro-tissue assembly in 3D tumor models
Authors: Pan Rong , Lin Chenyu , Yang Xiaoyan , Xie Yuanyuan , Gao Lixia , Yu Ling 
Published: April 2024

Abstract
Three-dimensional (3D) cell culture has been used in many fields of biology because of its unique advantages. As a representative of the 3D systems, 3D spheroids are used as building blocks for tissue construction. Larger tumor aggregates can be assembled by manipulating or stacking the tumor spheroids. The motivation of this study is to investigate the behavior of the cells distributed at different locations of the spheroids in the fusion process and the mechanism behind it. To this aim, spheroids with varying grades of maturity or age were generated for fusion to assemble micro-tumor tissues. The dynamics of the fusion process, the motility of the cells distributed in different heterogeneous architecture sites, and their reactive oxygen species profiles were studied. We found that the larger the spheroid necrotic core, the slower the fusion rate of the spheroid. The cells that move were mainly distributed on the spheroid’s surface during fusion. In addition to dense microfilament distribution and low microtubule content, the reactive oxygen content was high in the fusion site, while the non-fusion site was the opposite. Last, multi-spheroids with different maturities were fused to complex micro-tissues to mimic solid tumors and evaluate Doxorubicin’s anti-tumor efficacy.
