Published: February 2023

Callicarpa subpubescens is endemic to the oceanic Ogasawara
Islands, and multiple ecotypes have been suggested to exist within
southern part of this group, the Hahajima Islands, each associated with
unique localized habitats. We determined the habitat characteristics of
each ecotype, the presence or absence of pre- and post-mating isolation,
the amount of gene flow among ecotypes in adult trees and naturally
pollinated seeds using EST-SSR markers, and discussed how ecotypes are
maintained in this species. There were four ecotypes in the Hahajima
Islands, one of which presumed to be derived from hybridization of the
remaining two ecotypes. The spatial distribution and habitat of each
ecotype showed distribution which have depended on the suitable
environment for each ecotype, i.e. local adaptation. The leaf morphology
and size distribution of each ecotype also indicated the appropriate
forms for each habitat. Flowering times more or less overlap among the
ecotypes, indicating that pre-mating isolation is not perfect.
Artificial cross-pollination showed that no post-mating isolation exists
between ecotypes. Hybridization rates in adult trees and naturally
pollinated seeds were 37.2% and 26.4%, respectively, and most of the
hybrids were backcrosses and few F1. The hybridization rates of each
ecotype and paternal correlation indicated that the flowering synchrony
and spatial distribution of ecotypes contributed to hybridization among
ecotypes. The reversion to the original ecotype which adapted to the
environment through backcrossing would contribute to the maintenance of
the ecotypes.

Published: February 2023

The simultaneous consideration of various economic, social, and
environmental factors in determining the proper location for
constructing a sports complex for traditional games is crucial to the
continuation of such events. This research takes a two-stage approach
when studying where to locate such infrastructure. In the first stage,
namely, that of ranking the locations, the criteria influencing the
evaluation are categorized based on the research literature and on
interviews with experts well-versed in social, economic, and
environmental questions. The criteria identified in this stage are
divided into two broad categories: intra-city (selecting the most
suitable city) and inter-city (identifying the most suitable geographic
area). The best geographical area for constructing a sports complex is
found using intra-city criteria based on expert opinions. These opinions
were obtained using an online questionnaire prepared according to the
Best Worst Method (BWM), giving the weights of both categories. In an
effort to assess the desirability of the cities under consideration, we
apply piecewise linear pereference functions (PLPFs) to determine the
ranges in which each of the items achieve their best score. In the
second stage, i.e., the geographical area selection stage, and according
to the weighting of inter-city criteria and the ideal distance to each
criterion (e.g., fire stations and hospitals), the best geographical
area for constructing a sports complex is selected using geographical
information system (GIS). The results of this research confirm that
social factors are more important than economic and environmental ones
in the evaluation phase of the candidates and PLPFs produce different
results vis- à-vis the existing linear methods.

Published: February 2023

As implantable medical electronics (IMEs) developed for healthcare
monitoring and biomedical therapy are extensively explored and deployed
clinically, the demand for non-invasive implantable biomedical
electronics is rapidly surging. Current rigid and bulky implantable
microelectronic power sources are prone to immune rejection and
incision, or cannot provide enough energy for long-term use, which
greatly limits the development of implantable medical devices. Herein, a
comprehensive review of the historical development of IMEs and the
applicable miniaturised power sources along with advantages and
limitations is given. Despite recent advances in microfabrication
techniques, biocompatible materials have facilitated the development of
IMEs system toward non-invasive, ultra-flexible, bioresorbable, wireless
and multifunctional, progress in the development of minimally invasive
power sources in implantable systems has remained limited. Here we
summarise three promising minimally invasive power sources, including
energy storage devices (biodegradable primary batteries, rechargeable
batteries and supercapacitors), human body energy harvesters
(nanogenerators and biofuel cells) and wireless power transfer
(far-field radiofrequency radiation, near-field wireless power,
ultrasonic and photovoltaic power). The energy storage and harvesting
mechanism, configurational design, output power and applications in vivo
are discussed. It is expected to give a comprehensive understanding of
the IMEs for painless health monitoring and biomedical therapy with
long-term stable function
Disparities and Therapeutic Advances in Cystic Fibrosis
Authors: Palla John
Published: February 2023

Cystic fibrosis has seen a multitude of therapeutic advances targeting
its downstream effects. This has led to a steady increase in survival
over the past few decades. The recent development of disease-modifying
drugs targeting the underlying CFTR mutation has revolutionized
treatment for CF. Despite these advances, individuals with CF who are
racial and ethnic minorities, from low socioeconomic status, or female
sex have worse clinical outcomes. The inequitable access to CFTR
modulators from cost and/or genetic eligibility has the potential to
further worsen the existing health disparities seen within the CF
community.
Deciphering the evolutionary mechanisms of SARS-CoV-2; Absence of ORF8 protein and its potential advantage in the emergence of viral lineages
Authors: Velazquez Lauro
Published: February 2023

To date (2/5/2023), nearly three years after the official declaration of
the COVID-19 pandemic, a total of 754, 018, 841 cases and 6,817,478
deaths have been officially reported to the world health organization
(WHO) ([https://covid19.who.int/](https://covid19.who.int/)). During
this time, the global populace has witnessed the devastating effects of
this pandemic, which can undoubtedly be considered the sanitary event of
the century. In my opinion, understanding the mechanisms associated with
the evolution of SARS-CoV-2 is the most important aspect of
understanding the course of this pandemic. In this respect, the millions
of viral sequences generated during the pandemic (1) have significantly
aided in the tracking of the pandemic, resulting in the identification
of multiple variants of concern.
Process evaluation of a pharmacist-led intervention aimed at deprescribing and appropriate use of cardiometabolic medication among people with type 2 diabetes
Authors: Baas Gert , Crutzen Stijn , Smits Sanne , Denig Petra , Taxis Katja , Heringa Mette
Published: February 2023

Background: A quasi-experimental study investigated a pharmacist-led
intervention aimed at deprescribing among patients with type 2 diabetes
at risk of hypoglycaemia. Objective: To evaluate the process of
implementing the intervention in primary care in order to understand
variations in implementation and outcomes. Methods: Mixed-methods study
based on the Grant-framework, with 10 domains, including recruitment of
patients, delivery of the intervention, and response of pharmacists and
patients. Data collected were: administrative logs, semi-structured
observations of patient consultations (n=8), interviews with pharmacists
(n=16), and patient-reported experience measure (PREM) questionnaires
(n=66; response 73%). Results: Ninety patients from 14 pharmacies were
included. Although the selection of patients based on high
hypoglycaemia-risk was considered useful, pharmacists experienced
barriers to proposing deprescribing in patients with recent medication
changes, patients without current health problems or hypoglycaemic
events, and patients treated in secondary care. The consultation aid and
deprescribing tool provided were evaluated positively by the
pharmacists. The majority of patients were satisfied with the service
and information that the pharmacists provided. Conclusion: Pharmacists
and patients were positive about the intervention. Both groups valued
the consultation on deprescribing, supported by tools. To optimise the
effect, improvements can be made to patient selection and local
agreements on proactive deprescribing.
Vertical Free-Swinging Photovoltaic Racking Energy Modelling: A Novel Approach to Agrivoltaics
Authors: Pearce Joshua M. , Hayibo Koami Soulemane
Published: February 2023

To enable lower-cost building materials, a free-swinging bifacial
vertical solar photovoltaic (PV) rack has been proposed, which complies
with Canadian building codes and is the lowest-capital-cost agrivoltaics
rack. The wind force applied to the free-swinging PV, however, causes it
to have a non-90° tilt angle and no energy performance model accurately
describes such a system. To provide a simulation model for the
free-swinging PV, where wind speed and direction govern the array tilt
angle, this study builds upon the open-source System Advisor Model (SAM)
using Python. After the SAM python model is validated, a view factor
model is used to calculate front and back irradiations. The findings
reveal that free-swinging PV generates 12% more energy than vertical
fixed-tilt PV. Free-swinging PV offers a levelized racking cost, which
is 30% lower than that of other agrivoltaics racks including commercial
fixed-tilt metal, optimized fixed-tilt wood, and seasonally-adjusted
wood PV racking.
Prevalence of ‘Atoms of Confusion’ in Open Source Java Systems: An Empirical Study
Authors: Tahsin Noshin , Fuad Nafis , Satter Abdus
Published: February 2023

Atoms of confusion, or simply “atoms,” are pieces of code that
lead to misunderstanding while being interpreted. Previous research has
shown that the presence of atoms has an effect on code readability.
Aside from simple misunderstanding in lab setting, atoms of confusion
are common and meaningful in open source C and C++ projects, and are
thus removed by bug-fix commits. However, due to syntactical differences
between language paradigms, the prevalence of atoms may vary in projects
written in other languages (e.g. Java), which is yet to be explored. In
this study, the first step is taken towards investigating the prevalence
of 12 different atoms in the 13 most popular open-source Java projects.
The relationship between the presence of atoms and aspects of code
maintainability is also studied. Results show that, atoms are 4.7 time
more prevalent in Java projects compared to open source C/C++ projects
based on occurrence per line. For a total of 1085223 atoms in our
corpus, they occur once every 4.8 lines. Some atoms are very obscure
(e.g. the Logic As Control Flow atom which occurs once in 440060 lines).
Some atoms are frequently occurring (e.g. the Infix Operator Precedence
atom which occurs once in 6.4 lines). Impact of the presence of atoms on
code maintainability is also explored. Besides, correlation between
atoms are investigated. Results indicate that object oriented metrics
contribute less in atom prevalence, whereas fine grained code-metrics
have relatively better association.
Causes and consequences of changing oxygen availability in lakes
Authors: Carey Cayelan
Published: February 2023

Changing oxygen availability in lakes and reservoirs is a fundamental
limnological challenge of our time, with massive consequences for
freshwater ecosystem functioning and water quality. Cross-lake surveys,
paleolimnological studies, and long-term monitoring records indicate
that many lakes are exhibiting declines in both surface and bottom-water
oxygen availability due to climate and land use change, though a few
lakes are exhibiting increases in oxygen. By analyzing time series of
oxygen monitoring data from ~400 lakes, I find that some
lakes may be experiencing a decoupling of surface and bottom oxygen
dynamics: variability in surface oxygen concentrations is decreasing in
some lakes while variability in bottom oxygen concentrations is
increasing. Changes in both oxygen concentrations and variability have
many implications for lake functioning because oxygen concentrations
control many ecosystem processes. Consequently, lake ecosystem
provisioning and cultural services (e.g., drinking water, fisheries,
recreation) will likely be impaired by declining oxygen, whereas the
effects of changing oxygen on regulatory and supporting ecosystem
services (e.g., nitrate removal through denitrification,

that were proven for composition operators on Bloch spaces.
Fixed point results under nonlinear Suzuki (F,R≠)-contractions with an application
Authors: Arif Mohammad , Imdad Mohammad
Published: February 2023

In this article, we introduce the idea of nonlinear Suzuki
(F,R?)-contractions, which is patterned after the contractive conditions due
to Suzuki [Nonlinear Anal. 71 (2009) 5313-5317] and Wardowski [Fixed Point
Theory Appl. (2012) 94:6]. Utilizing our newly introduced contraction, we
establish some relation theoretic fixed point theorems. Furthermore, we adopt
an example to highlight the genuineness of our newly proved results.
Finally, we use our main results to establish the existence and uniqueness
of solution for a nonlinear matrix equation.

Effects of 16% Carbamide Peroxide on Optical Properties of Thermally Aged Monolithic CAD-CAM Glass Ceramics with Different Surface Treatments
Authors: Murat Sema , Batak Burcu , Yilmaz Deniz , Öztürk Caner
Published: February 2023

This study aimed to investigate the effects of 16% carbamide peroxide (CP) on the relative translucency parameter (RTP) and color stability of thermally aged CAD-CAM glass-ceramics with glazing or polishing. Three different CAD-CAM blocks—feldspathic (VM), lithium disilicate (IPS), and zirconia-reinforced lithium silicate ceramic (VS)—were used in this study. The specimens were divided into two groups (n=10) according to surface treatments (glazing or polishing). Bleaching treatment with 16% CP was applied to the thermally aged specimens. A spectrophotometer (VITA Easyshade Advance) was used to measure the CIE L*a*b*coordinates of the specimens on white and black backgrounds, and RTP and color difference (ΔE00) values were calculated. The surface topography of the specimens and the atomic weight of the elements were analyzed with scanning electron microscopy and energy-dispersive x-ray. The data were analyzed by using the two-way ANOVA test for ΔE00 values and two-way repeated measures ANOVA test for RTP and color parameters values (a=0.05) and the Tukey post-hoc test was used for multiple comparisons of the groups. RTP values were statistically influenced by material type, bleaching, and finishing technique, and the interaction among these factors was found to be significant (p<0.05). ΔE00 values were statistically influenced by material type, finishing technique, and the interaction among these factors was also found to be significant (p<0.05). IPS presented significantly lower RTP and ΔE00 values for both glazed and polished surfaces (p<0.05). 16% CP bleaching agent caused changes in translucency of aged VM and IPS at different levels. Glazed surfaces presented higher color stability in comparison to mechanically polished surfaces for VS (p<0.05).
Numerical investigation of lymph flow through pumping lymphatics
Authors:   , Medina Loeiz
Published: February 2023

This thesis aims at numerically modelling the lymphatic network at different scales. A failure of this network results in an accumulation of fluid in the area concerned, which can lead to lymphoedema.With the objective to understand this network and how it develops its ca-pacity to move lymph, we are interested in a comparison between different description and models on the lymphatic network from the literature. We first study the discrete approach in zero dimension and in one dimension. In addi-tion, the different constitutive equations observed in the literature are detailed and analysed. In order to understand the interactions between the basic motile elements of the lymphatic network, different methods for coupling calculations in fluid-structure simulation are presented. Then, with the help of different recent articles, we compare different approaches and geometries for the study of a lymphangion.In this zero-dimensional approach, a new numerical formulation is used for the calculation of lymph flow in the collecting network. Equations of this model are detailed in this document, and the number of parameters generally used in the constitutive equation is reduced. Moreover, these equations allow for a variable contraction frequency depending on the load imposed by the boundary condition applied. Different specific cases such as divergent and convergent bifurcations, elementary units of a network are first studied. Furthermore, lymphangions at the end of a channel appear to deliver more pumping energy than the initial ones. The results from the simulations are compared with experimental data. Finally, a specific and realistic network geometry extracted from an anatomical drawing of a leg is used to simulate the model and show complex synchronization behaviours between lymphangions. Three different regimes of synchronization between lymphangion in a channel are identified.For the last chapter, a two-dimensional model of a lymphangion is proposed, which will then be used to study the behaviour of valves, lymphocytes and walls. The operation of the multi-physics fluid-structure code is explained, it is based on a method called: Immersed Structural Potential Method (ISPM). Initially, the equations of fluid and solid mechanics are introduced, how they are coupled, as well as the details of their implementation. Then, we study the behaviour of a group of lymphocytes in the lymphatic channel using a fluid-structure interaction code. Using the geometry of a lymphangion, we compare the displacement of the lymphocytes in different cases, first with or without valve, pulsation of the fluid and then the moving walls. We observe that a poiseuille flow is maintained across the range of lymphocite density considered here. This type of flow is similar to that of red blood cells in a blood stream.

The field experiment was conducted in the rainy (Kharif, June to October) seasons of 2019 and 2020 at ICAR-Indian Agricultural Research Institute, New Delhi, India with the objective to appraise the effect of biofortified and non-biofortified varieties and zinc fertilization strategies on the growth, productivity and profitability of rice. The biofortified variety DRR Dhan 45 recorded a higher value of dry matter accumulation, leaf area index, and crop growth rate, and the non-biofortified variety Pusa 44 recorded higher effective tillers, panicle weight, filled grain weight per panicle, number of filled grains and total grains per panicle, fertility percentage and grain yield (5.2 t ha-1), though the performance of both varieties was statistically similar. But, the higher straw yield was recorded with the non-biofortified variety, Pusa Basmati 1121 (10.8 t ha-1). Pusa Basmati 1509 recorded higher cost of cultivation, gross returns, net returns and B:C. Among zinc fertilization strategies, soil application of 2.5 kg Zn ha-1 along with the foliar application of 0.5% ZnSO4.7H2O at maximum tillering and anthesis stages recorded higher growth parameters, yield, and yield attributes and better economics. On average, the soil+foliar Zn application increased grain yield by 14% and straw yield by 10.5%, and gross returns and net returns by 15.6% and 26.7%, respectively, than the control. Cultivation of rice varieties, Pusa 44 or DRR Dhan 45, along with soil+foliar Zn fertilization enhanced growth and productivity, while the aromatic variety, Pusa Basmati 1509 enhanced the profitability.

1282-1328 yılları arasında Bizans İmparatorluğu tahtında bulunan II. Andronikos Paleologos dönemi pek çok önemli meselenin yaşandığı bir süreçtir. Uzun yıllar devam eden iç savaş, artan vergiler ve düşman saldırılarına maruz kalan halkın devletle olan bağı zayıflamıştır. Kiliselerin birliği konusunda atılan adımların hem ruhban sınıfında hem de halkta yarattığı hoşnutsuzluk ile ilgilenmek durumunda kalan imparator vaktinin çoğunu dini meselelere harcamasına rağmen tam bir sükunet sağlayamamıştır. Bu zaman zarfında özellikle Türklerin Bizans aleyhinde ilerleyişi ihmal edilmiş, ekonomik iyileşme için kara ordusunu küçültülmüş, donanma dağıtılmıştır. Deniz gücü için tamamen İtalyan devlete bağımlı hale gelen imparatorluk Türk tehdidine karşı Alan ve Katalan paralı askerlere güvenmiştir. Ancak Katalan birliğinin imparatorluk topraklarına gelişi yarardan çok zarar getirmiş, Bizanslı ahali zulme uğradığı gibi bu birliklere yapılan ödemeler iperpiron değer kaybetmesine neden olmuştur. Bizans İmparatorluğu bu sıkıntılarla uğraşırken Anadolu’da çok sayıda Türkmen kendi beyleri etrafında örgütlenmiş ve bağımsız beylikler olarak harekete etmeye başlamıştır. Bunlardan biri olan Osmanlı Beyliği de Bizans topraklarına başarılı akınlar düzenlemiş ve 1302 tarihli Bafeus Savaşında Bizans birliklerini mağlup edecek kadar güçlenmiştir. Bu çalışmada, dönemin özellikle iç siyasetinde belirleyici olan unsurlara, hanedan içindeki çekişmelere ve II. Andronikos ile III. Andronikos arasında yaşanan iç savaşa, önemli Bizans kaynaklarından Nikiforos Grigoras’ın Romaiki Istoria isimli eserinden faydalanılarak değinilmeye çalışılmıştır.

El presente trabajo expone el marco teórico-conceptual de un estudio epidemiológico de una población infantil. La Organización Mundial de la Salud estima que una quinta parte de los niños y niñas a nivel mundial, sufren algún padecimiento de salud mental. Nuestro país cuenta con escasos estudios epidemiológicos en la materia, y son casi inexistentes los datos confiables a nivel nacional. Asimismo, se observan extendidas situaciones de maltrato y de violencia sexual, registrándose una marcada diferencia por según el género. Las Estas diferencias de género se observan también en las manifestaciones clínicas sintomáticas: los varones suelen presentar síntomas más “desadaptativos” para el entorno que las niñas, quienes muestran frecuentemente signos presentan frecuentemente síntomas de ansiedad o depresión que resultan inadvertidos. Por este motivo las niñas son derivadas a la consulta en mucha menor medida que los varones, o sólo tardíamente. La pronta detección del padecimiento psíquico en la niñez permitirá realizar intervenciones psicológicas tempranas y preventivas.

Species, abundance, time of appearance of fly larvas in white rats (Rattus norvegicus Berkenhout 1769) carcass with different burnt times
Authors: Putra Ichsan Luqmana Indra , Rahmadi Muhammad Izzuddin Noor
Published: February 2023

The use of insects in determining PMI is still little. The flies during the period of laying eggs and forming larvae can estimate the time of death. This study aims to determine the type, abundance, and time of appearance of fly larvae on white rat carcasses that were treated with burning. The experiment was conducted on 12 female white rats of the wistar strain, aged 2-3 months, healthy, and weighing 150-200 g. The research was experimental which consisted of 4 treatments with 3 repetitions of each treatment. The treatment was given by first anesthetizing the rats using 10% ether, then dislocating the cervical spine. After being sacrificed, the rats were burned using stainless tongs over a fire with variations in burning time, namely A (10 minutes), B (20 minutes), and C (30 minutes). The carcasses of each treatment were placed in an open field with a distance of 2.5 meters between the carcasses. Observations were made for 5 days until the carcass underwent complete decomposition. Larvae were taken from each carcass using tweezers, then put into vials containing 70% alcohol. The larvae were then identified morphologically in the laboratory. There were types of fly larvae found in the burnt treated white rat carcasses, namely Sarcophaga argyrostoma and S. haemorrhoidalis, while the controls were Chrysomya albiceps, C. megacephala, and C. bezziana. S. argyrostoma was found with the highest abundance in the treatment (39.9 individuals), while C. albiceps was found in the control (346.2 individuals). The first fly larvae that appeared in the burning treatment were S. argyrostoma (31 hours) and those of the control C. megacephala (31 hours). The conclusion of this study is that the variation of combustion has or does not affect the type, abundance, and time of appearance of fly larvae on the carcass.
Mosquito larvicidal activity of Hyptis capitata leaves ethanolic extract and fraction against Culex quinquefasciatus
Authors: To'bungan Nelsiani , Jati Wibowo Nugroho
Published: February 2023

Larvicidal potential of Hyptis capitata grown in Indonesia has not been extensively studied. Its leaves are extracted with the maceration method using ethanol as the solvent. Furthermore, this study aims to use the ethanolic leaf extract of the H. capitata for larvicidal assays against instar III/IV larvae of Culex quinquefasciatus with different concentrations, including 1000, 500, 250, 125, and 62.5 µg/mL. Fractionation of the extract was carried out by vacuum liquid chromatography, and obtained four fractions, namely fractions F1, F2, F3, F4. Fractions were also used for the larvicidal assay. The constituents of the extract were then analyzed with the GC-MS method to predict the components involved in its toxicity. Larvicidal data obtained were analyzed using regression analysis to determine the LC50 value. Analysis of variance was carried out with one-way ANOVA using Tuckey HSD-test on the SPSS ver. 26 at 95% confidence and significance P<0.05. H. capitata ethanolic leaf extract has a higher level of toxicity than its fraction, with LC50 value 990.90 µg/mL. H. capitata ethanolic leaf extract are capable of providing a toxic effect on larvae, with a mortality percentage of up to 50% more. Some compounds that were assumed to play a role in its toxicity include pentadecanoic acid, 2,6,10,14-tetramethyl-, methyl ester; 1-heptadecyne; 9-tetradecen-1-ol, acetate; oxyrane, deodecyl-; 9,12,15-octadecatrienal; and 6,11-dimethyl-2,6,10-dodecatrien-1-ol. These finding indicate that the ethanolic leaf extract of H. capitata has the potential to be developed as a biolarvicidal agent against C. quinquefasciatus.
