Enhanced power supply circuitry with long duration and high‐efficiency charging for indoor photovoltaic energy harvesting internet of things end device
Authors: Wang Chung‐Hsiang , Huang Kuo‐Hsuan , Wu Chung‐Yen 
Published: March 2024

AbstractLight is a popular choice as an indoor energy source for Internet of Things (IoT) end devices. However, indoor light sources are intermittent, which can disrupt the operation of IoT end devices, potentially leading to safety concerns or inaccurate data. Therefore, there is a growing need to develop a long‐duration power supply for IoT end devices. The energy from ambient light is harnessed to charge a supercapacitor through an energy manager chip. This supercapacitor serves as the power source for IoT nodes when the ambient light is unavailable. Nevertheless, as the voltage of the supercapacitor drops below the operating threshold, the IoT end node will eventually shut down. This paper proposes a circuit that utilizes a Joule Thief circuit, booster converter, and capacitor stack‐up circuit to extract the remaining energy from the supercapacitor and boost the voltage, thereby extending the operational lifespan of IoT end nodes. Additionally, capacitor stack‐up circuits significantly enhance charging efficiency. PSpice design and simulations confirm circuit feasibility. High‐efficiency charging and long‐duration IoT nodes suggest replacing traditional batteries with supercapacitors, reducing environmental impact.
A new born‐approximation approach to compute the effects of motion on the solution of electromagnetic problems involving moving materials with stationary boundaries
Authors: Raffetto Mirco , Clemente Vargas Mario Rene , Zeyde Kirill 
Published: March 2024

AbstractThe non‐relativistic motion of media induces very weak effects on electromagnetic fields. For this reason, it is extremely difficult to compute such effects with traditional techniques. To overcome this difficulty, a novel approach is introduced in this work. It is based on the Born approximation of the solution of electromagnetic problems involving media in motion. The formulation of these problems makes use of equivalent field sources and is specifically tailored to find the effects of motion on the electromagnetic field. The new methodology exploits traditional simulators able to deal with media at rest. The motion of the materials has to be managed by specific programs performing simple algebraic calculations. The simplest of the methods proposed does not present any additional complexity with respect to more traditional approaches to the same problems. All methods deal with time‐harmonic electromagnetic fields and, for this reason, they can manage materials in motion with stationary boundaries. A complete set of simulations for cylinders moving in the axial direction show that the new methods outperform traditional numerical approaches and, in some significant cases, traditional approaches based on semi‐analytical techniques. The good features of the new methodology are shown to hold true for a range of velocity values spanning 11 decades; such a range covers most of the applications of practical interest.
Fast fitting of spectral lines with Gaussian and hyperfine structure models
Authors: Juvela Mika , Tharakkal Devika 
Published: March 2024

Context. The fitting of spectral lines is a common step in the analysis of line observations and simulations. However, the observational noise, the presence of multiple velocity components, and potentially large data sets make it a non-trivial task.
Aims. We present a new computer program Spectrum Iterative Fitter (SPIF) for the fitting of spectra with Gaussians or with hyperfine line profiles. The aim is to show the computational efficiency of the program and to use it to examine the general accuracy of approximating spectra with simple models.
Methods. We describe the implementation of the program. To characterise its performance, we examined spectra with isolated Gaussian components or a hyperfine structure, also using synthetic observations from numerical simulations of interstellar clouds. We examined the search for the globally optimal fit and the accuracy to which single-velocity-component and multi-component fits recover true values for parameters such as line areas, velocity dispersion, and optical depth.
Results. The program is shown to be fast, with fits of single Gaussian components reaching on graphics processing units speeds approaching one million spectra per second. This also makes it feasible to use Monte Carlo simulations or Markov chain Monte Carlo calculations for the error estimation. However, in the case of hyperfine structure lines, degeneracies affect the parameter estimation and can complicate the derivation of the error estimates.
Conclusions. The use of many random initial values makes the fits more robust, both for locating the global χ2 minimum and for the selection of the optimal number of velocity components.

Obstetric and Neonatal Outcomes Following Hospital Transfers of Home Births and Births in Midwife-led Units in Austria
Authors: Schildberger Barbara , Riedmann Marina , Leitner Hermann , Stelzl Patrick 
Published: March 2024

AbstractHome births and births in midwife-led units and the associated potential risks are still
being debated. An analysis of the quality of results of planned home births and births in
midwife-led units which require intrapartum transfer of the mother to hospital provides
important information on the quality of processes during births which occur outside hospital
settings. The aim of this study was to analyze neonatal and maternal outcomes after the
initial plan to deliver at home or in a midwife-led unit had to be abandoned and the mother
transferred to hospital.The method used was an analysis of data obtained from the Austrian Birth Registry. The
dataset consisted of singleton term pregnancies delivered in the period from 1 January 2017
to 31 December 2021 (n = 286056). For the analysis, two groups were created for comparison
(planned hospital births and hospital births recorded in the Registry as births originally
planned as home births or births in midwife-led units but which required a transfer to
hospital) and assessed with regard to previously defined variables. Data were analyzed using
frequency description, bivariate analysis and regression models.In Austria, an average of 19% of planned home births have to be discontinued and the
mother transferred to hospital. Home births and births in midwife-led units which require
transfer of the mother to hospital are associated with higher intervention rates
intrapartum, high rates of vacuum delivery, and higher emergency c-section rates compared to
planned hospital births. Multifactorial regression analysis showed significantly higher
risks of poorer scores for all neonatal outcome parameters (Apgar score, pH value, transfer
rate).If a birth which was planned as a home delivery or as a delivery in a midwife-led unit
fails to progress because of (possible) anomalies, the midwife must respond and transfer the
mother to hospital. This leads to a higher percentage of clinical interventions occurring in
hospital. From the perspective of clinical obstetrics, it is understandable, based on the
existing data, that giving birth outside a clinical setting cannot be recommended.

Abstract
Background The European Society of Plastic, Reconstructive and Aesthetic
Surgery (ESPRAS) comprises 40 national societies across Europe. In addition to
ESPRAS, there are 8 different European Plastic Surgery societies representing
Plastic Surgeons in Europe. The 4th European Leadership Forum (ELF)
of ESPRAS, held under the motto “Stronger together in Europe” in Munich in 2023,
aimed to collect and disseminate information regarding the national member
societies of ESPRAS and European societies for Plastic Surgeons. The purpose was
to identify synergies and redundancies and promote improved cooperation and
exchange to enhance coordinated decision-making at the European level.
Material and methods An online survey was conducted regarding the
organisational structures, objectives and challenges of national and European
societies for Plastic Surgeons in Europe. This survey was distributed to
official representatives (Presidents, Vice Presidents and General Secretaries)
and delegates of national and European societies at the ELF meeting. Missing
information was completed using data obtained from the official websites of the
respective European societies. Preliminary results were discussed during the
4th ELF meeting in Munich in March 2023.
Results The ESPRAS survey included 22 national and 9 European Plastic
Surgery societies representing more than 7000 Plastic Surgeons in Europe. Most
national societies consist of less than 500 full members (median 182 members
(interquartile range (IQR) 54–400); n=22). European societies, which covered the
full spectrum or subspecialities, differed in membership types and congress
cycles, with some requiring applications by individuals and others including
national societies. The main purposes of the societies include research,
representation against other disciplines, specialisation and education as well
as more individual goals like patient care and policy regulation.
Conclusion This ESPRAS survey offers key insights into the structures,
requirements and challenges of national and European societies for Plastic
Surgeons, highlighting the relevance of ongoing close exchange between the
societies to foster professional advancement and reduce redundancies. Future
efforts of the ELF will continue to further explore strategies for enhancing
collaboration and harmonisation within the European Plastic Surgery
landscape.
Cephalometric Evaluation in Patients with Obstructive Sleep Apnea undergoing Lateral Pharyngoplasty
Authors: Zanco Stephanie Regiane Prata Ferreira , Duarte Bruno Bernardo , Almeida Aurélio Rochael , Mendonça José Alexandre 
Published: March 2024

Abstract
Introduction Lateral pharyngoplasty (LP) has shown promising results. Craniofacial deformity reduces the pharyngeal space, contributing to the etiopathogenesis. The analysis of craniofacial features can be performed using cephalometry.
Objective To verify if craniofacial deformity is associated with worse polysomnographic data in patients with obstructive sleep apnea (OSA), and to verify if the preoperative cephalometric parameters can interfere with the surgical success of the LP.
Methods The study included 21 patients with OSA aged between 18 and 65 years who underwent LP in a university hospital from 2015 to 2019. Polysomnography was performed postoperatively, after a minimum period of 6 months from the surgical procedure. In addition, a cephalometric evaluation was performed to assess craniofacial deformity, and to correlate it with the polysomnographic results.
Results The mean and median of all polysomnographic respiratory parameters improved postoperatively, especially the apnea-hypopnea index (AHI), which went from 40.15 to 16.60 events per hour (p = 0.001). Of the 21 patients, 15 showed improvements in the AHI postoperatively. As for the cephalometric evaluations, we found that the longer the distance between the hyoid bone and the mandibular plane, the greater the patient's preoperative AHI (p = 0.011). When assessing whether cephalometric changes related to craniofacial deformities influence the surgical outcome of LP, no correlation was found for any cephalometric measurement.
Conclusion The longer the distance between the hyoid bone and the mandibular plane, the greater the preoperative AHI, and LP was an effective OSA treatment. Cephalometric variables are not able to modify or determine the success of LP in apneic patients in the population assessed.

Median cleft of mandible and lower lip with ankyloglossia and ectopic minor salivary gland on tongue
Authors: Rana Roshani E. , Puri Vinita A. , Thakkur Rahul K. , Baliarsing A. S. 
Published: March 2024

ABSTRACTMedian cleft of lower lip and mandible is a rare anomaly. This Cleft has also been described as Cleft No. 30 of Tessier's classification. In minor forms only lower lip is cleft. Frequently, the cleft extends into the mandibular symphysis and the tongue is attached to the cleft alveolar margin. At times the tongue may be bifid or absent, hyoid absent, thyroid cartilage underdeveloped, strap muscles atrophic, manubrium sterni absent, clavicles widely spaced etc. The earliest report of this anomaly was by Couronne' in 1819. Since then very few cases have been reported in literature with variations. We describe a male child who presented at the age of 6 months with an ectopic salivary gland on the dorsum of the tongue in addition to median cleft of lower lip, ankyloglossia and notching of the mandible. Excision of mass on dorsum of tongue, release of ankyloglossia and lip from the alveolus followed by repair was done. No bony work was done since the mandible was only notched. On post-operative follow-up at 18 months, dentition was delayed in both maxillary as well as mandibular teeth and there was a gap between the lower central incisors. At the age of 2 years 4 months, the dentition is still not complete and the gap between the lower central incisors is very apparent. There is a supernumerary upper central incisor on right side. There is no mobility between the two segments of mandible. Speech is normal. A regular follow-up will be done to study the eruption of permanent central incisors at the age of 7 years and till eruption of all permanent teeth to assess the occlusion and to decide whether any bony work is needed or not.
Closed rupture of the flexor digitorum profundus tendon of little finger: A case report
Authors: Agarwal Pawan 
Published: March 2024

ABSTRACTClosed rupture of the FOP tendon is rare. However, whenever they occur the most common site of rupture is the tendon-bone insertion, less frequent site is at the musculo-tendinous junction. Midsubstance ruptures are even more unique and are usually due to underlying pathology such as fracture, cystic degeneration, rheumatoid arthritis, or sequel following local steroid injection. This report describes a closed rupture of FOP tendon of little finger. Mechanism of injury, diagnosis and management are discussed.
Macromastia of pregnancy: A unique presentation of this rare clinicohistopathological entity

Published: March 2024

ABSTRACTThe present case is a unique presentation of a patient who developed a small lump in her breast during her first pregnancy but it was only during her third pregnancy that it increased in size and became a huge fungating mass. Although, gigantic sizes of this pathologic entity have been reported, the present case had the involved breast hanging till below the inguinal ligament and required sling to support the breast. Since the pre-operative diagnosis was suggestive of cystosarcoma phylloides, no attempt at reconstructive surgery was contemplated.
Vibrational signatures of dynamic excess proton storage between primary amine and carboxylic acid groups

Published: March 2024

Ammonium and carboxylic moieties play a central role in proton-mediated processes of molecular recognition, charge transfer or chemical change in (bio)materials. Whereas both chemical groups constitute acid–base pairs in organic salt-bridge structures, they may as well host excess protons in acidic environments. The binding of excess protons often precedes proton transfer reactions and it is therefore of fundamental interest, though challenging from a quantum chemical perspective. As a benchmark for this process, we investigate proton storage in the amphoteric compound 5-aminovaleric acid (AV), within an intramolecular proton bond shared by its primary amine and carboxylic acid terminal groups. Infrared ion spectroscopy is combined with ab initio Molecular Dynamics (AIMD) calculations to expose and rationalize the spectral signatures of protonated AV and its deuterated isotopologues. The dynamic character of the proton bond confers a fluxional structure to the molecular framework, leading to wide-ranging bands in the vibrational spectrum. These features are reproduced with remarkable accuracy by AIMD computations, which serves to lay out microscopic insights into the excess proton binding scenario.
Study on condensation of oily particles under the influence of water vapor phase transition
Authors: Wang Xin , Zhang Qi , Yang Luying , Li Tian , Yang Yang 
Published: March 2024

To address the problem that oily fine particles are too small to be easily captured by traditional dust removal equipment, which hinders improving the purification efficiency, this paper proposes using the technical principle of water vapor phase transition to conduct experiments and simulations. A set of water vapor experimental devices for fine particles of oil mist is designed, and the data are analyzed by a Grimm spectrometer. The experimental results show the phase change of water vapor has a remarkable effect on the agglomeration of oily fine particles. Phase change condensation makes the particle size of fine particles increase by 5–10 times in a truly brief time, and the polymerization and removal efficiency are greatly improved. To analyze the changes of the coalescence characteristics in a larger range of parameter changes, the Euler multiphase flow model is adopted, the particle condensation growth rate function is introduced by a user-defined function to establish a coalescence model and the heterogeneous condensation growth characteristics of oily particles are analyzed in a supersaturated water vapor environment. The simulation results show that the condensing chamber temperature of the condensing chamber is 283 K, and the lower the air flow rate of the condensing chamber, the more favorable the heterogeneous condensation growth of oil particles. The change rule of agglomeration characteristics of oily particles obtained by experiment and simulation proves the feasibility of improving the removal efficiency of oily fine particles.
A fence of opportunity
Authors: Olivas Osuna José Javier 
Published: March 2024

Abstract
This article deconstructs the parliamentary discourses regarding two migratory incidents in Ceuta, May 2021, and
Melilla, June 2022, when hundreds of people attempted to cross the fences that separate Morocco from Spain. Most of them were
immediately deported, many injured, and several died. This analysis compares the density of populist, anti-populist, re-bordering,
and de-bordering references in forty-five speeches at the Spanish Congress regarding both tragic events. Vox speakers articulate a
distinct discourse that instrumentalises these incidents to convey a sense of existential crisis and to (re)define a populist
right-wing political identity based on moral hierarchies, a homogenising conception of society and the exclusion of a dangerous
“other.” Meanwhile some parties applied a populist logic to promote de-bordering views and others combined re-bordering and
de-bordering claims without imposing a populist frame. This was an opportunity to exhibit a progressive sense of place in
borderlands contrasting with Vox’s reactionary one.
