This study aims to analyze the factors that can influence people’s perceptions of intention to search for mobile banking information to support daily activities, as well as the influence of mobile banking on public interest or Depositor’s Islamic banking and conventional banking. We use the Google Search Volume Index from one of the popular Islamic banking and conventional banking “Mobile banking” keywords in Google Trends to estimate the relationship between individual interest in Islamic banks and Convensional banks, and Islamic bank deposits and Conventional banks. This study shows that the keyword “mobile banking” coefficient has a non-significant correlation with Islamic bank deposits and conventional banks, which cannot be concluded. Although the number of deposits of Islamic banks and conventional banks is determined by many determinants. This investigation proves that the factors that have not been exploited to date, such as variables that cannot be quantified or not measurable (eg, popularity and curiosity), can be examined with the help of Google Trends.

Authors: Insani D S , Muflih M
Published: November 2019

The purpose of this study is to investigate the determinants of Islamic banks performance using quarterly time series data from 2013 to 2017 of 12 Islamic commercial banking in Indonesia. Data analysis used Panel Least Square model with E-views that examined the impact of Banks specific (size, capital adequacy, liquidity Risk and operating cost), Income diversification and macro-economic (Gross Domestic Product and inflation) on bank performance (Return on Assets). The result shows that ROA is negatively related to liquidity risk, Operating Cost and inflation. This research is expected to be able to add information and references about the performance of Islamic banks and to develop short-term and long-term plans and strategies for management to optimize financial bank performance that can contribute to economic growth.
E-creative Industry Based on Japanese Food
Authors: Tawami T , Sopyana P T
Published: November 2019

This study aims at proving that the Indigenous Japanese food is demanded by various circles of society in Indonesia. The food is very influenced by the geographical location of the area and historical differences, therefore the food is a cultural element of a State. The method used in the study was a survey method. The results of the research show that there are a lot of typical Japanese foods that do not exist in Indonesia and is expected to give it a try. So, the chances of Japanese food in Indonesia is quite large. Thus, making a business of Japanese restaurant in Indonesia with a different menu and more variety would be advantageous. In addition, special food can become the Pull of a country to attract foreign tourists to come visit.

Computation of Kazhdan-Lusztig polynomials and some applications to finite groups
Authors: Lübeck Frank
Published: November 2019

We discuss a practical algorithm to compute parabolic Kazhdan-Lusztig polynomials. As an application we compute Kazhdan-Lusztig polynomials which are needed to evaluate a character formula for reductive groups due to Lusztig.

Some coefficients of these polynomials have interesting interpretations for certain finite groups. We find examples of finite dimensional modules for finite groups with much higher dimensional first cohomology group than in all previously known cases.

Some of these examples lead to the construction of finite groups with many maximal subgroups, contradicting an old conjecture by G. E. Wall.
Single-Stage Augmentation Mastopexy With Composite Reverse Inferior Muscle Sling Technique for Autologous Reinforcement of the Inferior Pole: Technical Refinements and Outcomes
Authors: Munhoz Alexandre Mendonça , Neto Ary Marques , Ferrari Orlando
Published: November 2019

Background

Single-stage augmentation mastopexy (SAM) is a common procedure, but revision rates are high. Muscle slings have been used in SAM, but despite satisfactory outcomes, most studies do not include objective or accurate measurements of implant/breast position. This article describes a surgical technique for SAM employing a composite reverse inferior muscle sling (CRIMS).

Objectives

The authors sought to assess outcomes from primary SAM procedures utilizing the CRIMS technique in a cohort of patients operated on by a single surgeon.

Methods

Thirty-two patients (60 breasts) aged a mean of 43.1 ± 6.8 years underwent primary CRIMS mastopexy to treat severe ptosis (grade III-IV) in 25 patients (78.1%). The average implant volume was 255 cc (range, 215-335 cc). Three-dimensional imaging obtained from the Divina scanner system was employed to evaluate lower pole stretch and lower pole arc and to determine long-term ptosis.

Results

Four cases of complications were observed in 3 patients (9.3%), minor dehiscence in 2 and capsular contraction in 1, during a mean follow-up of 42 months. The value for lower pole stretch was 5.5% (P < 0.0001) between 10 days and 1 year, with the majority occurring early in the first 6 months, indicating that lower pole arc remained steady during the last months of follow-up.

Conclusions

Advances in techniques have led to improvements in aesthetic outcomes following SAM, and CRIMS can play a helpful role. Our results show this procedure is suitable for patients with breast ptosis, with acceptable complication rates and the added bonus of implant stabilization within the pocket.

Enable Traditional Laptops with Virtual Writing Capability Leveraging Acoustic Signals

Human–computer interaction through touch screens plays an increasingly important role in our daily lives. Besides smartphones and tablets, laptops are the most prevalent mobile devices for both work and leisure. To satisfy the requirements of some applications, it is desirable to re-equip a typical laptop with both handwriting and drawing capability. In this paper, we design a virtual writing tablet system, VPad, for traditional laptops without touch screens. VPad leverages two speakers and one microphone, which are available in most commodity laptops, to accurately track hand movements and recognize writing characters in the air without additional hardware. Specifically, VPad emits inaudible acoustic signals from two speakers in a laptop and then analyzes energy features and Doppler shifts of acoustic signals received by the microphone to track the trajectory of hand movements. Furthermore, we propose a state machine-based trajectory optimization method to correct the unexpected trajectory and employ a stroke direction sequence model based on probability estimation to recognize characters users write in the air. Experimental results show that VPad achieves the average error of 1.55 cm for trajectory tracking and the accuracy over 90% of character recognition merely through built-in audio devices on a laptop.
