Structure Functions and Parton Densities: a Session Summary
Authors: Nachman Benjamin , Wichmann Katarzyna , Zurita Pia
Published: July 2022

Studies of fragmentation and parton density functions are a core component of research in high energy particle and nuclear physics. These quantities are inherently interesting as a probe of the quantum nature of the strong force and are also essential ingredients to additional studies in high energy scattering experiments. These proceedings provide an overview of the state of the art in this area, as presented at the Deep-Inelastic Scattering Conference in the Spring of 2021.
Recent results from heavy ion collisions at LHCb
Authors: Boente García Óscar
Published: July 2022

LHCb is a fully instrumented spectrometer covering the forward
rapidity region at the LHC, which provides unique access to the small
Bjorken-xx
region inside the nucleus. In this contribution, a selection of recent
results from the LHCb heavy-ion program are presented, including a
measurement of charged hadron production in proton-proton (pp) and
proton-lead (pPb) collisions, \chi_{c2}/\chi_{c1}χc2/χc1
production in pPb collisions, and coherent
J/\psiJ/ψ
production in peripheral and ultra-peripheral PbPb collisions.
Comparisons with calculations and effects from the nuclear PDFs and
dense QCD medium are discussed.
Transverse Single-Spin Asymmetries of Midrapidity Direct Photons and Neutral Mesons at PHENIX
Authors: Lewis Nicole
Published: July 2022

Results are presented for the transverse single-spin asymmetries of
direct photons, neutral pions, and eta mesons for
|\eta|<0.35|η|<0.35
from p^\uparrow + pp↑+p
collisions with \sqrt{s} = 200s=200
GeV at PHENIX. As hadrons, \pi^0π0
and \etaη
mesons are sensitive to both initial- and final-state effects and at
midrapidity probe the dynamics of gluons along with a mix of quark
flavors. Because direct photon production does not include
hadronization, the direct photon TSSA is only sensitive to initial-state
effects and at midrapidity provides a clean probe of the gluon dynamics
in transversely polarized protons. All three of these results will help
constrain the collinear twist-3 trigluon correlation function as well as
the gluon Sivers function, improving our knowledge of spin-dependent
gluon dynamics in QCD.
Measuring single-top-associated Higgs production at the HL-LHC
Authors: Bahl Henning
Published: July 2022

Precision measurements of top-associated Higgs production are an important ingredient to unravel the CP nature of the Higgs boson. In this work, we constraint the CP nature of the top-Yukawa coupling taking into account all relevant inclusive and differential Higgs boson measurements. Based upon this fit, we show that it is crucial to disentangle single- and di-top-associated Higgs production for tightening indirect constraints on a CP-odd top-Yukawa coupling in the future. In this context, we propose an analysis strategy for measuring tH production at the HL-LHC without relying on assumptions about the Higgs CP character.

Authors: Flore Carlo , Lansberg Jean-Philippe , Shao Hua-Sheng , Yedelkina Yelyzaveta
Published: July 2022

We study inclusive J/\psiJ/ψ
photoproduction at NLO at large P_TPT
at HERA and the EIC. Our computation includes NLO QCD
leading-P_TPT
corrections, QED contributions via an off-shell photon as well as those
from J/\psiJ/ψ+charm
channels. For the latter, we employ the variable-flavour-number scheme.
Our results are found to agree with the latest HERA data by H1 and
provide, for the first time, a reliable estimate of the EIC reach for
such a measurement. Finally, we demonstrate the observability of
J/\psiJ/ψ+charm
production and the sensitivy to probe the non-perturbative charm content
of the proton at high xx,
also known as intrinsic charm, at the EIC.
PERLE - ERL Test Facility at Orsay
Authors: Bogacz S.  Alex
Published: July 2022

PERLE (Powerful ERL for Experiments)[1] is a novel Energy Recovery Linac (ERL) test facility, designed to validate choices for a 50 GeV ERL foreseen in the design of the Large Hadron Electron Collider (LHeC) and the Future Circular Collider (FCC-eh), and to host dedicated nuclear and particle physics experiments. Its main thrust is to probe high current, continuous wave (CW), multi-pass operation with superconducting cavities at 802 MHz. With very high transient beam power (10 MW), PERLE offers an opportunity for controllable study of every beam dynamic effect of interest in the next
generation of ERL design and becomes a ‘stepping stone’ between present state-of-art 1 MW ERLs and future 100 MW scale applications.
Hard color-singlet exchange in dijet events in proton-proton collisions at $\sqrt{s} = 13$ TeV
Authors: Baldenegro Barrera Cristian
Published: July 2022

We present a measurement of events with two jets separated by a
pseudorapidity gap (jet-gap-jet). The signature is expected from hard
color-singlet exchange. The jets are reconstructed with the CMS
detector. The highest p_\text{T}pT
jets have p_\text{T}^\text{jet1,2} > 40pTjet1,2>40
GeV, with 1.4 < |\eta^\text{jet1,2}| < 4.71.4<|ηjet1,2|<4.7
and \eta^\text{jet1} \eta^\text{jet2} < 0ηjet1ηjet2<0.
We measure the fraction of color-singlet exchange dijet events,
f_\text{CSE}fCSE,
and compare it to previous measurements and to predictions. We also
study jet-gap-jet events where the colliding protons remain intact and
are detected with the Roman pots of TOTEM. A larger fraction
f_\text{CSE}fCSE
is found in the latter subsample.
Sivers asymmetry in inelastic $J/ψ$ leptoproduction at the EIC
Authors: Sangem Rajesh , D'Alesio Umberto , Mukherjee Asmita , Murgia Francesco , Pisano Cristian
Published: July 2022

We study the Sivers asymmetry in inelastic
J/\psiJ/ψ
leptoproduction, ep^\uparrow \to e+ J/\psi+Xep↑→e+J/ψ+X,
within a transverse momentum dependent scheme, the so-called generalized
parton model (GPM). The effects of final-state interactions are properly
taken into account by employing the color-gauge invariant GPM (CGI-GPM).
For the J/\psiJ/ψ
formation the non-relativistic QCD (NRQCD) framework is adopted.
Predictions for unpolarized cross sections and maximized Sivers
asymmetries at EIC energies are given.
Charmonium and bottomonium spectroscopy at Belle II
Authors: Thampi Ashish
Published: July 2022

The Belle II experiment at the SuperKEKB energy-asymmetric
e^{+}e^{-}e+e−
collider is an upgrade of the BB
factory facility at KEK in Tsukuba, Japan. The experiment began
operation in 2019 and aims to record a factor of 50 times more data than
its predecessor. Belle II is uniquely capable of studying the so-called
“XYZ” particles: heavy exotic hadrons consisting of more than three
quarks. First discovered by Belle, these now number in the dozens, and
represent the emergence of a new category within quantum chromodynamics.
We present recent results obtained from Belle II data, and the future
prospects to explore both exotic and conventional quarkonium
physics.
Drell-Yan $p_{\bot}$ with NLO-matched Parton Branching TMDs at energies from fixed-target to LHC
Authors: Lelek Aleksandra
Published: July 2022

The description of the Drell-Yan (DY) transverse momentum spectrum
requires matching of fixed order QCD calculations with soft gluon
resummation up to all orders in the QCD coupling. It has been noticed in
the literature that a consistent description of DY data in a wide
kinematic regime from fixed-target to LHC energies is problematic. In
this work the predictions for transverse momentum spectrum of DY data
coming from experiments in very different kinematic ranges (NuSea, R209,
Phenix, LHC 8 TeV and 13 TeV center-of-mass energies
\sqrt{s}s)
are calculated by applying transverse momentum dependent (TMD) parton
distributions obtained from the Parton Branching (PB) method, combined
with the next-to-leading-order (NLO) calculation of the hard process in
the MCatNLO method. We discuss the problems involved in matching of the
fixed order calculation and resummation, especially in the moderate to
low mass and p_{\bot}p⊥
region accessible at fixed target experiments. We find that at low DY
mass and low \sqrt{s}s
even in the region of p_{\bot}/Q\sim 1p⊥/Q∼1
the contribution of multiple soft gluon emissions (included in the
PB-TMDs) is essential to describe the measurements, while at larger
masses and LHC energies the contribution from soft gluons in the region
of p_{\bot}/Q\sim 1p⊥/Q∼1
is small.

Published: July 2022

OBJECTIVE: The aim of this study is to evaluate the outcomes of gonadotropin-releasing hormone agonist treatment for ovarian cysts, which are developed during tamoxifen use due to breast cancer.
STUDY DESIGN: This was a retrospective cohort study including the patients who were under tamoxifen treatment due to stage I-III breast cancer and who were administered leuprolide acetate for ovarian cysts with low malignancy risk between 2012-2020.
RESULTS: Leuprolide acetate was administered to a total of 16 patients with ovarian cysts. The median age was 39.5 (33-52), the median size of the ovarian cyst was 42.5 (39-79) mm, and the median duration of tamoxifen use was 22 (7-36) months. Leuprolide acetate was administered at doses of 3.75 mg for 1 month at 10 (62.5%) patients, 7.5 mg in two months at 3 (18.75%) patients, and 11.25 mg in three months at 3 (18.75%) patients. Ovarian cysts were regressed after treatment at 13 patients, while 3 patients underwent surgery.
CONCLUSION: Leuprolide acetate can be used as an option in the treatment of ovarian cysts that develop in breast cancer patients under tamoxifen therapy. Keywords: Breast neoplasms, Gonadotropin-releasing hormone, Ovary, Ovarian cyst, Tamoxifen
Automatic model calibration of combined hydrologic, hydraulic and stormwater quality models using approximate Bayesian computation
Authors: Chowdhury Anupam , Egodawatta Prasanna
Published: July 2022

A range of automatic model calibration techniques are used in water engineering practice. However, use of these techniques can be problematic due to the requirement of evaluating the likelihood function. This paper presents an innovative approach for overcoming this issue using a calibration framework developed based on Approximate Bayesian Computation (ABC) technique. Use of ABC in automatic model calibration was undertaken for a combined urban hydrologic, hydraulic and stormwater quality model. The simulated runoff hydrograph and total suspended solid (TSS) pollutograph were compared with observed data for multiple events from three different catchments, and found to be within 95% confidence intervals of the simulated results. The R programmed model was validated by comparing simulated flow with similar commercially available modeling software, MIKE URBAN output determined using mean value of parameters obtained from the calibration exercise, and performed well by satisfying statistical criteria's such as coefficient of determination (CD), root mean square error (RMSE) and maximum error (ME). The developed framework is useful for automatic calibration and uncertainty estimation using ABC approach in complex hydrologic, hydraulic and stormwater quality models with multi-input-output systems.

Authors: Seno Eloize , Caseli Helena , Inácio Marcio , Anchiêta Rafael , Ramisch Renata
Published: July 2022

O crescente interesse pelo processamento semântico automático, especialmente por parte dos pesquisadores de Compreensão e de Geração de Língua Natural, tem levado a muitas pesquisas relacionadas ao desenvolvimento de parsers semânticos. E, nesse contexto, a AMR (Abstract Meaning Representation) é um dos formalismos de representação semântica que tem recebido mais atenção recentemente, devido à sua maneira relativamente simples de capturar o significado de uma sentença. A construção de parsers AMR é em grande parte baseada em córpus de referência anotados por humanos. Contudo, esse recurso é ainda bastante escasso para muitas línguas como o português. Por esse motivo, várias pesquisas têm explorado o uso de abordagens entre línguas (cross-lingual), que partem de córpus e parser existentes em uma língua fonte, para o desenvolvimento de recursos semânticos para outras línguas alvo. Dado esse contexto, este artigo descreve o XPTA, um parser AMR para o português (PT) que se baseia na abordagem entre línguas (cross-lingual, X). O XPTA parte de parser AMR existente para o inglês e de vários recursos linguísticos-computacionais bilíngues inglês--português e mapeia o conhecimento semântico disponível no inglês para a representação do significado equivalente em português. Uma avaliação automática do XPTA mostrou que a abordagem adotada é promissora e os valores obtidos para Smatch (66%, no melhor caso) apontaram que o modelo tem potencial para competir com os resultados apresentados na literatura para outros idiomas. Além da análise automática, uma análise qualitativa dos grafos gerados possibilitou identificar e categorizar os principais erros do modelo e suas possíveis causas.
Convergence time aware switch migration algorithm for SDN (CTSMA) cloud datacenter
Authors:   Department of Information Science and Engineering, Dr. Ambedkar Institute of Technology, Bangalore, India, et al. Deepu
Published: July 2022

Multi-controller deployment in a software-defined network improves the system's stability and scalability. However, since network traffic fluctuates, it presents a new problem for balancing loads on remote controllers. Controller Adaption and Migration Decision (CAMD) and Dynamic and Adaptive Load Balancing (DALB) frameworks are developed for efficient balancing of load on the controller to solve the problem of controller overload due to dynamic network traffic. CAMD was considered to be more efficient than DALB, but when the network is more dynamic, and the incoming traffic flow is elephant flow this leads to the overall reduction in system performance. This study proposed a Convergence Time aware Switch Migration Algorithm (CTSMA) that solved the network challenge when the network is more dynamic and incoming traffic flow is more. This research developed an enhanced switch migration algorithm to address the network difficulty of dynamically changing incoming load. Because of the imbalanced distribution of load on the controllers, processing flows will have longer response times and the controllers' throughput will be reduced. Switch migration is the best method of resolving the issue. Present techniques, on the other hand, focus solely on load balancing performance while ignoring migration efficiency, thereby leading to large migration costs and excessive control overheads. To increase the load and migration efficiency of controllers, this research work developed a convergence time aware switch migration method. To find the group of underloaded controllers in the network, the improved framework looked at controller volatility and average load status. Performance comparison indicators included controller throughput, reaction time, and convergence time. According to simulation studies, CTSMA outperforms CAMD by cutting controller reaction time by roughly 6.1%, increasing controller throughput by 8.0% on average, keeping a decent load balancing rate, lowering migration costs, and maintaining the best load balancing rate.

Objective: to evaluate the clinical efficacy of targeted therapy with omalizumab in children with moderate to severe uncontrolled bronchial asthma. Materials and methods: 7 children receiving omalizumab therapy in a hospital and polyclinic of the Ufa City Children’s Clinical Hospital No. 17 were under observation. In accordance with the instructions for use, the monoclonal antibody drug omalizumab was administered subcutaneously every 2-4 weeks. The dosage of the drug was determined based on the child’s body weight and the initial level of serum IgE. The anamnesis of life and disease, the results of instrumental and laboratory research methods, the results of AST and c-AST tests were studied in all the children studied. Results: against the background of therapy with omalizumab in children, there was a significant decrease in the frequency of daytime symptoms (p=0.0179), a decrease in the frequency of night symptoms (p=0.0233), increased physical activity (p=0.0179), a decrease in the need for bronchodilators (p=0.0179), an increase in FEV1 according to spirography (p=0.0431), a decrease in the volume of basic anti-inflammatory therapy with a decrease in the dose of IGCS in 71.43% of patients (p=0.0425), a significant increase in the number of AST and c–AST test scores: before treatment 12 [10; 13] points, against the background of treatment - 23 [20; 25] points, (p=0.0277). During the follow-up period of therapy with omalizumab, no serious adverse reactions were detected. Conclusion: thus, targeted therapy using omalizumab is clinically effective in children with moderate to severe uncontrolled bronchial asthma.
Autoinflammatory disease syndrome of hyperimmunoglobulinemia D
Authors: Somova T. M.
Published: July 2022

Objective: present a clinical case of a rare autoinflammatory disease. Materials and methods: an analysis of a clinical case of mevalonate kinase deficiency syndrome in an 8-year-old girl was carried out. Results: mevalonate kinase deficiency syndrome (SDMC) is a rare autoinflammatory disease with an autosomal recessive inheritance mechanism. The severity of the disease correlates with the residual activity of the enzyme mevalonate kinase, which is involved in the biosynthesis of cholesterol and isoprenoids, which is necessary for the conversion of mevalonate into the final product. As a result, the body accumulates mevalonic acid, especially high levels of it are found in the urine. A relatively mild SDMC phenotype is distinguished: hyperimmunoglobulinemia syndrome D (first described as HIDS in 1984) and a severe variant – mevalonic aciduria. A little more than 300 patients with SDMC have been described in the world. The disease is manifested by intermittent fever, arthralgia, pharyngitis, cervical lymphadenitis, urticarial rash resembling urticaria, less often vasculitis-like manifestations in the form of petechial-purple elements. Diagnosis is based on the activity of the mevalonate kinase enzyme in the blood or skin cells, biochemical analysis of urine (high numbers of mevalonic acid), as well as genetic confirmation of a mutation in the mevalonate kinase gene. The main principles of therapy for autoinflammatory diseases are the control of clinical symptoms and inflammation in general, as well as the prevention of amyloidosis. Conclusion: if an autoinflammatory process in the body is suspected, it is necessary to conduct a genetic study for timely diagnosis and the appointment of pathogenetic therapy to improve the quality of life and prevent complications.

Published: July 2022

Type 1 autoimmune polyglandular syndrome (APS1) is a rare disease, with an unknown prevalence in the Russian population. Due to the low awareness of doctors, it takes more time to make the accurate diagnosis and provide correct medical care. This article describes classical features of APS1 and a clinical case of a patient, who did not have one of the most common first manifestation of the disease - mucocutaneous candidiasis. Hypocalcemia was detected much later than the first clinical manifestations in the form of generalized seizures occurred. Patient also suffers from tapetoretinal abiotrophy, he completely lost vision in childhood which made it difficult for the doctor and patient to interact in the treatment of the disease.
Risk factors for the implementation of intrauterine adhesions in women of reproductive age
Authors: Orazov M. R. , Mikhaleva L. M. , Ismailzade S. Ya.
Published: July 2022

Childless marriages remain an important medical and social problem at present, both in our country and around the world. Infertility is a violation of the reproductive system, which has a wide range of conditions that affect one of the most important human functions – the ability to reproduce. The uterine factor of infertility occupies one of the leading positions in the formation of both primary and secondary infertility. Given the growth of acquired forms of uterine infertility, it is impossible not to turn to such a disease as intrauterine adhesions. Intrauterine synechiae is an acquired uterine disease that occurs after an injury to the endometrial mucosa. In the modern world, the prevalence of intrauterine adhesions in women of the reproductive period is increasing every year. However, it should be noted that despite modern technologies, it is impossible to accurately determine the number of women who have intrauterine adhesions. Taking into account the multifactorial development of intrauterine adhesions, as well as the low effectiveness of treatment methods, this problem occupies one of the leading positions in the structure of gynecological diseases and remains relevant. The asymptomatic course of the adhesive process leads to difficulty in diagnosis, and therefore the clinician needs to be aware of the risk factors for the development of intrauterine synechiae. The review presents risk factors for the formation of intrauterine synechiae.

From Supernatural to Psychological: A Historical Study of the Concept of the 'Fantastic' in Hoffmann’s ‘The Sandman’ and Poe’s ‘The Tell-Tale Heart’
Authors: Saeed Alan Ali
Published: July 2022

This research paper explores how and why the existing tradition of supernatural stories about ghosts and other fantastical creatures, which located terror as an external factor in these unnatural and malignant beings, was transformed in the early to mid-Nineteenth Century into tales that are instead focused on fear in terms of the internal psychology of the narrator and the protagonist. It investigates two well-known examples of psychological horror, E.TA. Hoffmann’s “The Sandman” (1816) and Edgar Allan Poe’s “The Tell-Tale Heart” (1843).
The research paper deploys a contextual historical approach examining the impact of Romanticism as a philosophy focusing on the individual’s mental state and extreme psychological situations, as well as developing scientific ideas about psychology in the period. In my argument it is “madness” (which could affect anyone in society) that became the new fear that haunted and fascinated society, replacing the explicitly external supernatural. I also use Tzvetan Todorov’s structuralist theory and model of “the fantastic” and suggest it is possible for a psychological tale to be fantastic in a different way than he envisages, insofar as madness is itself an experience where the victim is never sure if what they experience is real or unreal.
Hemodialysis Record Sharing: Solution for Work Burden Reduction and Disaster Preparedness
Authors: Ido Keisuke , Miyazaki Mariko , Nakayama Masaharu
Published: July 2022

Background

After the Great East Japan Earthquake in 2011, backup systems for clinical information were launched in Japan. The system in Miyagi Prefecture called the Miyagi Medical and Welfare Information Network (MMWIN) is used as a health information exchange network to share clinical information among various medical facilities for patients who have opted in. Hospitals and clinics specializing in chronic renal failure require patients’ data and records during hemodialysis to facilitate communication in daily clinical activity and preparedness for disasters.

Objective

This study aimed to facilitate the sharing of clinical data of patients undergoing hemodialysis among different hemodialysis facilities.

Methods

We introduced a document-sharing system to make hemodialysis reports available on the MMWIN. We also recruited hospitals and clinics to share the hemodialysis reports of their patients and promoted the development of a network between emergency and dialysis clinics.

Results

In addition to basic patient information as well as information on diagnosis, prescription, laboratory data, hospitalization, allergy, and image data from different facilities, specific information about hemodialysis is available, as well as a backup of indispensable information in preparation for disasters. As of June 1, 2021, 12 clinics and 10 hospitals of 68 dialysis facilities in Miyagi participated in the MMWIN. The number of patients who underwent hemodialysis in Miyagi increased by more than 40%.

Conclusions

Our backup system successfully developed a network of hemodialysis facilities. We have accumulated data that are beneficial to prevent the fragmentation of patient information and would be helpful in transferring patients efficiently during unpredictable disasters.
The Long-term Effects of Immersive Virtual Reality Reminiscence in People With Dementia: Longitudinal Observational Study
Authors: Huang Ling-Chun , Yang Yuan-Han
Published: July 2022

Background

Novel nonpharmacological therapies are being developed to prevent cognitive decline and reduce behavioral and psychological symptoms in patients with dementia. Virtual reality (VR) reminiscence was reported to improve anxiety, apathy, and cognitive function immediately after intervention in individuals at residential aged care facilities. However, its effect on elderly patients with dementia and how long this effect could last remain unknown.

Objective

The aim of this paper is to investigate the effect of immersive VR reminiscence in people with dementia both immediately after and 3-6 months after intervention.

Methods

A pilot study was conducted in 2 dementia care units. VR reminiscence therapy sessions were conducted twice per week for a 3-month period. Cognitive function, global status, depressive symptoms, and caregiver burden were assessed before and immediately after VR intervention in 20 participants. Subsequently, 7 participants were reassessed 3-6 months after the VR intervention. Wilcoxon sign-rank test was used for statistical comparisons of the changes.

Results

There were no significant changes in cognitive function, global status, and caregiver burden immediately after the VR intervention, but there was a significant reduction in depressive symptoms (P=.008). Moreover, compared with the cognitive function immediately after VR, it kept declining 3-6 months after.

Conclusions

Immersive VR reminiscence can improve mood and preserve cognitive function in elderly patients with dementia during the period of the intervention. Studies using a control group and comparing the use of VR with traditional forms of reminiscence should be conducted in the future to confirm and expand on these findings.
Development of a Noninvasive Blood Glucose Monitoring System Prototype: Pilot Study
Authors: Valero Maria , Pola Priyanka , Falaiye Oluwaseyi , Ingram Katherine H , Zhao Liang , Shahriar Hossain , Ahamed Sheikh Iqbal
Published: July 2022

Background

Diabetes mellitus is a severe disease characterized by high blood glucose levels resulting from dysregulation of the hormone insulin. Diabetes is managed through physical activity and dietary modification and requires careful monitoring of blood glucose concentration. Blood glucose concentration is typically monitored throughout the day by analyzing a sample of blood drawn from a finger prick using a commercially available glucometer. However, this process is invasive and painful, and leads to a risk of infection. Therefore, there is an urgent need for noninvasive, inexpensive, novel platforms for continuous blood sugar monitoring.

Objective

Our study aimed to describe a pilot test to test the accuracy of a noninvasive glucose monitoring prototype that uses laser technology based on near-infrared spectroscopy.

Methods

Our system is based on Raspberry Pi, a portable camera (Raspberry Pi camera), and a visible light laser. The Raspberry Pi camera captures a set of images when a visible light laser passes through skin tissue. The glucose concentration is estimated by an artificial neural network model using the absorption and scattering of light in the skin tissue. This prototype was developed using TensorFlow, Keras, and Python code. A pilot study was run with 8 volunteers that used the prototype on their fingers and ears. Blood glucose values obtained by the prototype were compared with commercially available glucometers to estimate accuracy.

Results

When using images from the finger, the accuracy of the prototype is 79%. Taken from the ear, the accuracy is attenuated to 62%. Though the current data set is limited, these results are encouraging. However, three main limitations need to be addressed in future studies of the prototype: (1) increase the size of the database to improve the robustness of the artificial neural network model; (2) analyze the impact of external factors such as skin color, skin thickness, and ambient temperature in the current prototype; and (3) improve the prototype enclosure to make it suitable for easy finger and ear placement.

Conclusions

Our pilot study demonstrates that blood glucose concentration can be estimated using a small hardware prototype that uses infrared images of human tissue. Although more studies need to be conducted to overcome limitations, this pilot study shows that an affordable device can be used to avoid the use of blood and multiple finger pricks for blood glucose monitoring in the diabetic population.
Perspectives on Ethical Issues Around the Use of Smartphone Apps for HIV Prevention in Malaysia: Focus Group Study With Men Who Have Sex With Men
Authors: Khati Antoine , Shrestha Roman , Rosen Aviana , Luces Jeffrey , Wickersham Jeffrey , Azwa Iskandar , Ab Halim Mohd Akbar
Published: July 2022

Background

The use of smartphone apps can improve the HIV prevention cascade for key populations such as men who have sex with men (MSM). In Malaysia, where stigma and discrimination toward MSM are high, app-based strategies have the potential to open new frontiers for HIV prevention efforts. However, little guidance is available to inform researchers about ethical concerns unique to the development and implementation of app-based HIV prevention programs.

Objective

This study aims to understand and characterize the attitudes and concerns of Malaysian MSM regarding HIV prevention mobile apps, particularly focusing on ethical aspects surrounding their use.

Methods

We conducted online focus group discussions with 23 MSM between August and September 2021. Using in-depth semistructured interviews, participants were asked about their perceived risks, benefits, and ethical issues associated with using mobile apps for HIV prevention. Each session was digitally recorded and transcribed. Transcripts were inductively coded using Dedoose software and analyzed to identify and interpret emerging themes.

Results

Overall, participants indicated a preference for using app-based strategies for HIV prevention efforts. Emerging themes on benefits related to app use for HIV prevention included convenience, anonymity (ability to remain anonymous while seeking care), less stigmatizing access to services (ability to avoid the burden and stigma of visiting an HIV clinic in person), readily accessible multimedia resources (eg, text, graphics, videos), and self-management portals (eg, medication adherence, appointment reminders). Prominent concerns raised by participants included privacy and confidentiality concerns, issues around personal health data storage and management, and fear of the Malaysian government accessing data.

Conclusions

The findings from this study indicate that app-based strategies for HIV prevention efforts are acceptable among Malaysian MSM. The results further highlighted the role of ethical concerns and the associated risks and benefits related to the use of app-based HIV prevention programs. Given the ever-evolving nature of such technological platforms and the complex ethical and legal landscape, such platforms must be safe and secure to ensure widespread public trust and uptake.
Prediction of Crash Risk based on Driving Behaviour
Authors: Manjunath Abhijna
Published: July 2022

Abstract: The major interest which is increasing for many kinds of applications includes human driver’s characterisation. There are different promising approaches in order to characterise the drivers by means of control theoretic driver models. The driver state is monitored by applying features of driver model from survey till real road distraction experiment. The dataset for the experiment consists of driving behavior with visuomotor and even few secondary tasks like auditory and even driving reference. The individual estimation of model parameters uses data of driving of nearly eleven drivers for error prediction identification. Few hand gestures and head movements are gentle way of getting distracted by drivers which covers many states like eye closure either short or long term. This paper represents the distraction detection system with the help of attention strategy. By matching the scaled features, the transformation of frontal face of the driver, driver recognition can be made. The severity of accident zone is found in particular area based on dataset. Driver behavior at particular hotspot location is found which is considered as the accident hotspot in order to gain better accuracy. The results help in validation of robustness and effectiveness of the model. Th

Import demand potential for Indonesian rubber products in ASEAN countries
Authors: Zainuddin Zainuddin
Published: July 2022

Increasing imports of rubber products from Indonesia is the key to the success of the downstream policy of rubber products to gain added value and job opportunities in the country. The rubber product market in ASEAN is more dynamic, and Indonesia must focus on strengthening competitiveness and exploiting potential markets. This paper aims to describe the potential demand for imports of Indonesian rubber products in ASEAN countries, especially Malaysia, Singapore, Thailand, the Philippines, and Vietnam. The flow of imports of rubber products uses the stochastic frontier panel data model to determine the potential demand for imports of Indonesian rubber products. Indonesian rubber products compete fiercely with similar industries in importing and exporting countries from East Asia. Indonesia mostly exports rubber products with HS codes 4015 and 4016 in the form of gloves, mittens, and mitts, rubber cellular, floor coverings and mats, erasers, gaskets and rings, boats, and fender docks to all markets in ASEAN countries. They were followed by rubber products with HS code 4010 in the form of conveyor belts or transmission belts from vulcanized rubber. The potential for import demand for other types of Indonesian rubber products (code HS4014, 4009, 4008) in ASEAN countries is relatively small and is growing slowly. Overall, the potential demand for imports of Indonesian rubber products tends to decline in ASEAN countries, as well as the actual imports of rubber products from Indonesia compared to their potential, which also declines slowly.

Evolutionary theory predicts that the process of range expansion will
lead to differences between core and edge populations in life-history
and dispersal traits. Selection and genetic drift can influence
reproductive ability, while spatial sorting by dispersal ability can
increase dispersal at the edge. However, the context individuals
experience (e.g., population density and mating status) also impacts
dispersal behavior. We evaluated theoretical predictions for evolution
of reproductive life-history and dispersal traits using the range
expansion of a biological control agent, Diorhabda carinulata, or
northern tamarisk beetle. We found divergence between core and edge
populations in fecundity, age at first reproduction, and female body
mass. We also show that density and mating status influence dispersal
and that dispersal increases at the edge of the range under some
conditions. We find support for most predictions about evolution during
range expansion, even across a heterogeneous environment, especially
when the ecological context is considered.

Published: July 2022

Using inequalities is a good way of studying topological indices.
Chemical graph theory is one of the nontrivial applications of graph
theory. In this paper, we examine and calculate another degree-based
topological index for silicon-carbide structures. The Sombor index,
which is a degree-based index, was introduced by Gutman in late 2020. In
this paper, we first calculate and compare the Sombor index, then the
decreasing Sombor index, and finally the mean Sombor index for a group
of silicon-carbide structures.

Ecosystem vulnerability in the Yellow River Basin (YRB) is a prominent
concern. An in-depth exploration of net primary productivity (NPP)
serves as an important aspect of assessing and protecting ecosystem
health. We explored spatiotemporal changes and influencing factors of
NPP in the YRB from 2000–2015, using a range of spatial analysis
techniques, and cutting-edge computing-intensive variable importance
decomposition methods. We found that NPP showed a fluctuating growth
trend over time, ranging from 181.0–259.1 gC∙m ∙a
, as well as a clear negative south-north spatial
gradient. Significant spatial clustering patterns were observed, with
Low-Low and High-High clusters being the dominant area classifications
at grid cell, county, and city scales in the study area. We also found
that NPP was statistically significantly affected by both natural
factors (including climate and topography), and human activities, whilst
meteorological factors were the most important factor and explained, on
average, roughly 66% of the variability in NPP. Although the impact of
human activities on NPP was relatively low when compared to natural
factors, the former tended to increase with time and accounted for
roughly 30% of the total variability explained by the model in 2015.
Overall, this study provides an improved technical framework for
undertaking a comprehensive analysis of the spatiotemporal pattern of
NPP and its influencing factors at multiple-spatial scales.
Liver-type fatty acid-binding protein: A hemodynamic index during extracorporeal membrane oxygenation

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support is
often essential for patients who experienced cardiac arrest. Although
lactate levels have been considered during hemodynamic management in
such cases, some patients with normal hemodynamics and oxygenation
exhibit elevated lactate levels due to the influence of underlying
diseases such as sepsis and malignant tumors. In contrast, urinary
liver-type fatty acid-binding protein (L-FABP), a biomarker of renal
ischemia and acute systemic ischemic injury, is less likely to be
affected by these factors, indicating that it may be a more sensitive
hemodynamic indicator than lactate. However, no previous reports have
discussed the use of L-FABP during VA-ECMO management of patients with
severe ischemic injury after cardiac arrest. Herein, we discuss a case
in which L-FABP measurements were used to manage a 46-year-old male
patient receiving VA-ECMO support. His mean blood pressure was ≥ 75 mmHg
for the first 24 h after the initiation of VA-ECMO, and he experienced a
rapid decrease in both L-FABP and lactate levels, the patterns of which
were similar. Weaning him off VA-ECMO was eventually successful based on
the combination of mechanical settings, echocardiographic parameters,
and hemodynamic indices. The current case suggests that measurement of
L-FABP levels can aid in selecting the target mean blood pressure,
determining whether to increase or decrease the flow rate of VA-ECMO,
and determining whether weaning from VA-ECMO is appropriate. As L-FABP
levels can be measured in approximately 10 minutes, they may have
substantial clinical value when rapid decision-making is required.
Canopy height, rather than neighbourhood effects, shapes leaf herbivory in a tropical rainforest

Published: July 2022

Factors shaping the interspecific variations in herbivory have puzzled
ecologists for decades and several hypotheses have been proposed. In a
tropical rain forest in Yunnan Province, China, we collected 6,732
leaves from 129 species with canopy heights ranging from 1.6 m to 65.0 m
above the ground. We tested the role of plant apparency, leaf traits and
the diversity, composition and structural heterogeneity of neighbors in
shaping the interspecific variations in herbivory. Results show that
leaf herbivory decreased with canopy height and specific leaf area and
increased with leaf size. However, neighboring species’ diversity,
composition, and structural heterogeneity showed no association with
herbivory. Therefore, neither the plant apparency hypothesis nor the
associational resistance hypothesis was supported in this hyper-diverse
tropical rainforest. Our results highlight the importance of vertical
structures and organic sizes in shaping herbivory patterns in natural
communities.
