Body dysmorphic features among Snapchat users of “Beauty-Retouching of Selfies” and its relationship with quality of life

Abstract Within the history of social networking applications the use of Snapchat has risen rapidly. Users of Snapchat can apply filters to change their appearance before they share photos. The present study aimed at assessing body dysmorphic features among Snapchat users of “Beauty-Retouching of Selfies” and its relationship with quality of life. A total of 507 Arab females participated in this study by responding to the Quality of Life (QOL) and Body Dysmorphic Features (BDF) scales as well as some demographic questions. Results showed that the mean of the body dysmorphic features was slightly above the theoretical mean of the BDF scale, which indicates that females who use Snapchat Beauty-Retouching features have a high tendency toward body dysmorphic features. Additionally, the quality of life mean was clearly above the theoretical mean of the QOL, which means that participants in general have a good quality of life. The study found a fundamental relationship between the two variables, QOL and BDF, and the relationship is in the negative direction. The results indicated that the relationship between BDF and QOL changes with age, educational levels, and social status. This study proposes further research to focus on identifying the most noteworthy factors influencing body image and QOL.
Language models for the prediction of SARS-CoV-2 inhibitors

The COVID-19 pandemic highlights the need for computational tools to automate and accelerate drug design for novel protein targets. We leverage deep learning language models to generate and score drug candidates based on predicted protein binding affinity. We pre-trained a deep learning language model (BERT) on ∼9.6 billion molecules and achieved peak performance of 603 petaflops in mixed precision. Our work reduces pre-training time from days to hours, compared to previous efforts with this architecture, while also increasing the dataset size by nearly an order of magnitude. For scoring, we fine-tuned the language model using an assembled set of thousands of protein targets with binding affinity data and searched for inhibitors of specific protein targets, SARS-CoV-2 Mpro and PLpro. We utilized a genetic algorithm approach for finding optimal candidates using the generation and scoring capabilities of the language model. Our generalizable models accelerate the identification of inhibitors for emerging therapeutic targets.
Exclusive breastfeeding practice and sources of support during COVID-19 pandemic in Indonesia

In 2018, the national coverage of exclusive breastfeeding among infants aged 0-5 months in Indonesia was still low. The COVID-19 pandemic can be a challenge to increase the coverage of exclusive breastfeeding. This study investigated the association between sources of breastfeeding supports and exclusive breastfeeding practices among mothers with infants aged under 6 months during the COVID-19 pandemic in Indonesia. This study used a cross-sectional study design through an online survey from November 2, 2020, to February 8, 2021. A total of 248 subjects were obtained through convenience sampling. Data analysis was done by bivariate analysis using Chi-square or Fisher’s exact test. Most of the subjects were aged 18-34 years old (90.7%), had higher education level (86.7%), had household income range Rp.3,000,000 – Rp.7,199,999 (39.2%), lived in Java Island (83.1%), had an infant aged ≤ 4 months (76.2%), and had a baby boy (51.2%). The proportion of exclusive breastfeeding was 79.0%. The most common sources of breastfeeding support were obtained from husband (91.1%) and health workers (65.7%), followed by family (62.9%). No significant association was found among all support sources on breastfeeding with exclusive breastfeeding. However, the proportion of exclusive breastfeeding among mothers who received husband support (80.1%) was higher than those who did not (68.2%). The most convenient and feasible breastfeeding supports that mother could obtain during pandemics were home-based supports. Mothers, their husbands, and families should be the priority target for health professionals to provide preventive and promotive breastfeeding intervention.
ULTRASOUND GUIDED HYDROSTATIC REDUCTION OF INTUSSUSCEPTION USING SALINE ENEMA IN PEDIATRIC POPULATION, DOES IT WORTH?

Background: Intussusception is an occlusive-strangulation form of intestinal obstruction, and all required precautions should be adopted as soon as possible to guarantee quick diagnosis and treatment in order to avoid intestinal ischaemia and necrosis. When facilities are available, nonoperative reduction is the first line of treatment; if that fails, operative management is the next logical step. Aim of work: The purpose of this study is to see how successful and safe it is to reduce intussusception with normal saline enema under guidance of ultrasound. Patients and methods: Our study comprised 37 children and was carried out at Benha Children's Hospital. Their ages varied from 4 to 36 months, with an 8-month median. Intussusceptions were diagnosed in all of them. Under ultrasound guidance, we used a sustained pressure of 100–120 cm H2O of saline enema per rectum and waited until the intussusceptum decreased or the retrograde movement ceased for up to 15 minutes. Results: The successful reduction rate was 89.2%. However, the recurrence rate was 18.7%, with successful non-operative reduction of all recurred cases. Only two of them required additional scheduled surgery due to pathological lead points. In the series, no procedure-related problems occurred. There were also no deaths. Conclusion: Because USGHR is a safe, effective procedure with a high success rate that does not require radiation exposure, we advocate it as the standard procedure and a suitable alternative to surgical surgery for managing paediatric intussusception.
Squamous Cell Carcinoma of the Oropharynx and the Effect of Botanicals

Context: Complementary and alternative medicines are currently being investigated for their usefulness in preventing, inhibiting, and reversing the progression of oropharyngeal squamous cell carcinoma (OSCC). Botanicals have great potential in cancer prevention because of their safety, low cost, and oral bioavailability. Objective: In this review, potential natural OSCCs' preventive botanicals and their mechanisms of action will be discussed. Methods: A brief bibliometric overview was conducted to obtain the available information of possible relevance to the issue. To this end, PubMed, Google and Google Scholar were interrogated for articles published in English between January 1, 2000, and December 31, 2010, that discuss botanicals and which could possibly be used in treating OSCC. The search was done to identify reports of botanicals' chemoprevention of OSCC. The study outcomes were evaluated and mechanisms of action were identified whenever possible. Results: A wide range of such botanicals had been shown to prevent 7, 12-dimethylbenz[a]anthracene or 4-nitroquinoline 1-oxide induced OSCC in animal model systems. However, only a few have been tested for their efficacy in humans. Animal model and cell culture studies have clarified that botanicals act by several mechanisms at various stages of OSCC. Discussion and Conclusions: By utilizing botanicals demonstrating potential mechanisms for efficacy, it is possible to maximize the chances of favorable outcomes while minimizing discomfort associated with conventional therapies.
Numerical optimization of broadband nonlinear microwave circuits

The implementation of extensive optimization capabilities in a general-purpose harmonic-balance simulator is described. Two different optimizers suitable for autonomous and forced circuits, respectively, are discussed in detail, and their merits and limitations are compared. The efficient numerical optimization of nonlinear microwave circuits specified over a finite frequency band is demonstrated. An example is given, showing that the procedure is very efficient, thus opening the way to the straightforward design of some modern monolithic microwave integrated circuit (MMIC) devices such as multioctave distributed mixers and power amplifiers. <<ETX>>
Multifunctional Non-Coding RNAs Mediate Latent Infection and Recurrence of Herpes Simplex Viruses

Abstract Herpes simplex viruses (HSVs) often cause latent infection for a lifetime, leading to repeated recurrence. HSVs have been engineered as oncolytic HSVs. The mechanism of the latent infection and recurrence remains largely unknown, which brings great challenges and limitations to eliminate HSVs in clinic and engineer safe oHSVs. Here, we systematically reviewed the latest development of the multi-step complex process of HSV latency and reactivation. Significantly, we first summarized the three HSV latent infection pathways, analyzed the structure and expression of the LAT1 and LAT2 of HSV-1 and HSV-2, proposed the regulation of LAT expression by four pathways, and dissected the function of LAT mediated by five LAT products of miRNAs, sRNAs, lncRNAs, sncRNAs and ORFs. We further analyzed that application of HSV LAT deletion mutants in HSV vaccines and oHSVs. Our review showed that deleting LAT significantly reduced the latency and reactivation of HSV, providing new ideas for the future development of safe and effective HSV therapeutics, vaccines and oHSVs. In addition, we proposed that RNA silencing or RNA interference may play an important role in HSV latency and reactivation, which is worth validating in future.

The corresponding cooling efficiencies were 80%, 90%, 90% and 83%.
Exploring the Synergy Between Industrial Ecology and System of Systems to Understand Complexity

Two objectives are pursued in this article. First, from a methodological perspective, we explore the relationships among the constructs of complex adaptive systems, systems of systems, and industrial ecology. Through examination of central traits of each, we find that industrial ecology and system of systems present complementary frameworks for posing systemic problems in the context of sociotechnical applications. Furthermore, we contend that complexity science (the basis for the study of complex adaptive systems) provides a natural and necessary foundation and set of tools to analyze mechanisms such as evolution, emergence, and regulation in these applications. The second objective of the article is to illustrate the use of two tools from complexity sciences to address a network transition problem in air transportation framed from the system‐of‐systems viewpoint and shaped by an industrial ecology perspective. A stochastic simulation consisting of network theory analysis combined with agent‐based modeling to study the evolution of an air transport network is presented. Patterns in agent behavior that lead to preferred outcomes across two scenarios are observed, and the implications of these results for decision makers are described. Furthermore, we highlight the necessity for future efforts to combine the merits of both system of systems and industrial ecology in tackling the issues of complexity in such large‐scale, sociotechnical problems.
Analog study of dead-beat posicast control

A method is presented which eliminates the oscillations and overshoot in a lightly damped servomechanism in a time of considerably less than one cycle of the uncompensated oscillation. The frequency response of a resonant system compensated in this manner can be made flat up through and beyond the resonant frequency of the system. For dead-beat response in one-half period, the frequency response is down only 3 db at the resonant frequency. Systems designed to have dead-beat responses in much less than one-half period have correspondingly wider bandwidths. The posicast method involves splitting up the input excitation into several fragments. Each fragment is applied at such a time that the sum of all the transient terms is equal to zero after the last excitation. The method is general and can be applied to electrical, mechanical, and even pneumatic systems.
Gate-induced drain leakage current enhanced by plasma charging damage

Correlation between gate-induced drain leakage (GIDL) current I/sub GIDL/ and plasma charging damage is investigated for p-MOSFETs. I/sub GIDL/ and maximum charge pumping current show the same trend as a function of antenna area ratio (AAR) and cell location. Enhancement of I/sub GIDL/ is mainly attributed to the increase of Si/SiO/sub 2/ interface traps generated in the plasma processes and is not related to the small amount of trapped charge in the oxide.
Mapping land cover using a developed U-Net model with weighted cross entropy

Abstract High-quality and high-productivity land cover data as a critical proxy are urgently needed for various communities. Although efforts in mapping projects had been made, various architectures to answer the challenges of Big Data of remote sensing are still needed. Therefore, this paper developed an improved U-Net model with weighted cross entropy (WCE) to map land covers. The accuracy was assessed by confusion matrix, and compared with the other two alternative cross-entropy loss functions. The comparisons highlighted an issue that unbalanced sample space of training dataset is a major cause of lower mapping accuracy. Also, the higher accuracy of U-Net with WCE implied its ability to handle the issue. This paper suggests an alternative solution for mapping land cover to address the challenges.
Factores que influyen en la decisión de licitar o no licitar en la Franja de Gaza – perspectivas de los contratistas

To bid or not to bid for a certain project is considered to be a crucial decision for contractors' survival. The objective of this paper is to identify and rank the factors that affect the bid/no bid decision according to their relative importance from the perspective of the local contractors operating in the Gaza Strip, Palestine. A total of seventy-eight factors were identified through a comprehensive literature review to evaluate the most important factors that affect the contractors' decisions to bid or not in the Gaza strip. A survey was conducted on a sample of seventy three contractors classified under the building category, and sixty five of them responded with response rate 89%. The results illustrate that, the financial capability of the contractors, the reputation of the clients, the financial capability of the clients, the financial values of the project, the availability of construction raw materials in the local markets, and the stability of the construction industry were the most critical factors affecting the contractors bid-no bid decisions. This study suggests that contractors and clients should improve their financial systems and capabilities in order to stay in business.
Early Track NEP system options for SEI missions

A development option for nuclear electric propulsion, the 'Early Track' option, is considered from system and mission application viewpoints. The intent of this development option is to address demanding missions of the future, such as robotic outer planet exploration or the Space Exploration Initiative. The 'Early Track' scheme utilizes existing technologies, such as the SP-100 space reactor and radiator components, as well as subsystems scalable from existing programs, such as 50 to 100 kWe ion thrusters. Up to 1.5 MWe of powder can be generated by the existing 2.4 MWt SP-100 reactor through the use of dynamic Rankine or Brayton power conversion. The performance characteristics of these systems are projected, and assessed for SEI missions currently under consideration.
Optimal operation of residential fuel cell system with rapidly fluctuating energy demand

Household cogeneration systems using proton exchange membrane fuel cells (PEMFC systems) have attracted attention due to their high energy efficiency. To bring out a PEMFC system's performance, it is crucial to use effectively both the electric power and hot water produced from a PEMFC system. Therefore, the optimal scheduling problem of a PEMFC system is very important. However, there are difficulties due to uncertainty of household energy demand. A difficulty to which little attention has been paid so far lies in the difference between the scheduled electric power output and the actual electric power output of a PEMFC system caused by rapid fluctuations in electric power demand. In this paper, we propose a new method of dealing with this problem. In our method, we treat the energy demand as a random variable and calculate its probability density at each time step. Then a constraint that takes account of the energy demand fluctuations is defined through the probability density and is incorporated into the original optimal scheduling problem of the PEMFC system. Using our method, we can deal with rapid energy demand fluctuations in settings of the scheduling problem with long time intervals. © 2011 Wiley Periodicals, Inc.

Instantaneous power compensation in three-phase systems by using p-q-r theory

This paper proposes a novel power compensation algorithm in three-phase four-wire power systems by using p-q-r theory. P-q-r theory is compared with two previous instantaneous power theories, p-q theory and cross-vector theory. P-q-r theory provides two-degrees of freedom to control the system currents by only compensating the instantaneous imaginary power without using any energy storage element. The definition of powers maintains conservatism, and agrees well with the general understanding of power. Simulation results show the superiority of p-q-r theory both in definition and compensation.
Experimentelle und numerische Untersuchungen zum Beulen von dünnen Scheiben aus UHPFRC unter Druckbeanspruchung

Ultrahochfester faserbewehrter Beton (UHPFRC) ermöglicht das Bauen mit äußerst dünnwandigen Elementen, die sowohl in der Architektur als auch im Konstruktiven Ingenieurbau viele Vorteile mit sich bringen. Die Schlankheit derartiger Bauteile übersteigt den gewohnten Bereich. Dies führt zu stark erhöhter Beulgefahr, weshalb neue Bemessungsregeln erarbeitet werden müssen. Der hier vorgestellte Beitrag zielt darauf ab, die grundsätzlichen Zusammenhänge im Tragverhalten von dünnwandigen UHPFRC‐Scheiben unter Druckbeanspruchung systematisch darzustellen, um eine Grundlage für die Ableitung geeigneter Ansätze für Berechnungsmodelle zu erhalten. Im Mittelpunkt der Arbeit stehen umfangreiche, experimentelle Untersuchungen, die einen großen Schlankheitsbereich abdecken. Um verlässliche Traglastergebnisse zu bekommen, wird eine spezielle Regelungstechnik entwickelt, mit der das an sich plötzlich eintretende Stabilitätsversagen so langsam abläuft, dass es sowohl messtechnisch als auch visuell über die Traglast hinaus erfasst werden kann. Für die Erleichterung der Auswertung und der Ergebnisinterpretation werden die Versuche mit detaillierten FE‐Simulationen untermauert und ergänzt.

A circuit topology for microwave modeling of plastic surface mount packages

A circuit topology is described for modeling a class of plastic surface mount packages. The model consists of three pieces each of which is circuit modeled based on an electromagnetic simulation. The resulting parts of the model can then be interconnected with each other and with the model of the monolithic microwave/millimeter wave integrated circuit (MMIC) to be packaged. Various interconnections and grounding schemes can be investigated without resorting to further electromagnetic simulation. The circuit model topology is verified by circuit simulating two simple packaged test circuits and comparing the results to a full electromagnetic simulation. The resulting S parameters are in good agreement over a wide range of frequencies and for a variety of grounding configurations.
MIlkabIlITy Of The IMpROveD v alaChIaN ewes DURINg MaChINe MIlkINg

The objective of this study was to evaluate the reaction of improved valachian ewes to machine milking and also to assess their milking characteristics. Bimodality is one of the most important indicators of milk ejection reflex during milking without the udder stimulation. The milk ejection reflex is an essential component for complete milk removal during milking. The trial was performed with 107 improved valachian ewes. Ewes were milked twice daily for two consecutive days in april at rotary milking machine with 36 milking stalls. The equipment for graduated electronic milk recording in jar was used. a computer was used for record ing the level of milk in jar at the second intervals. a total of 83 milk flow curves were evaluated. These curves were classified into five groups: 1 peak (1P), 2 peaks, bimodal curves (2P), plateau i (PLi, peak flow over 0.4 l/min), plateau ii (PLii, peak flow less than 0.4 l/min) and additional milk flow PL with bimodality (PLB). The ratio of different curve types (1P:2P:PLi:PLii:PLB) was 27:51:11:6:5%. The highest milk production was found in ewes with PLi (0.767 ± 0.053 l) as compared with PLB (0.497 ± 0.079 l), 2P (0.433 ± 0.024 l), 1P (0.250 ± 0.033 l) and the lowest milk production was measured in ewes with PLii (0.237 ± 0.070 l). obtained results indicate relatively high percentage of 1P milk flow pattern but more measurements is required to specify the ability of improved valachian to machine milking.
