Twisted layered material junctions,and in particular twisted graphene interfaces,exhibit fascinating physical properties of diverse nature including unique structural,tribological,electronic,as well as heat and electron transport characteristics [1].These properties are intimately related to the moire superstructure formed at the twisted interface,which induces atomic lattice reconstruction patterns that balance between inter-layer registry optimization and intra-layer strain minimization [2].

Zipf’s Law, Benford’s Law, and Pareto Rule

引用

Advances in Pure Mathematics 2023年第3期13卷 174-180页

作者： oded Kafri Kafri Nihul Ltd. Tel Aviv Israel

From a basic probabilistic argumentation, the Zipfian distribution and Benford’s law are derived. It is argued that Zipf’s law fits to calculate the rank probabilities of identical indistinguishable objects and that Benford’s distribution fits to calculate the rank probabilities of distinguishable objects. i.e. in the distribution of words in long texts all the words in a given rank are identical, therefore, the rank distribution is Zipfian. In logarithmic tables, the objects with identical 1st digits are distinguishable as there are many different digits in the 2nd, 3rd… places, etc., and therefore the distribution is according to Benford’s law. Pareto 20 - 80 rule is shown to be an outcome of Benford’s distribution as when the number of ranks is about 10 the probability of 20% of the high probability ranks is equal to the probability of the rest of 80% low probability ranks. It is argued that all these distributions, including the central limit theorem, are outcomes of Planck’s law and are the result of the quantization of energy. This argumentation may be considered a physical origin of probability.

Geometric Bone Modeling:From Macro to Micro Structures

Journal of Computer Science & Technology 2010年第3期25卷 614-622页

There is major interest within the bio-engineering community in developing accurate and non-invasive means for visualizing, modeling and analyzing bone micro-structures. Bones are composed of hierarchical bio-composite materials characterized by complex multi-scale structural geometry. The process of reconstructing a volumetric bone model is usually based upon CT/MRI scanned images. Meshes generated by current commercial CAD systems cannot be used for further modeling or analysis. Moreover, recently developed methods are only capable of capturing the micro-structure for small volumes （biopsy samples）. This paper examines the problem of re-meshing a 3D computerized model of bone micro- structure. The proposed method is based on the following phases： defining sub-meshes of the original model in a grid-based structure, remeshing each sub-mesh using the neural network （NN） method, and merging the sub-meshes into a global mesh. Applying the NN method to micro-structures proved to be quite time consuming. Therefore, a parallel, grid-based approach was applied, yielding a simpler structure in each grid cell. The performance of this method is analyzed, and the method is demonstrated on real bone micro-structures. Furthermore, the method may be used as the basis for generating a multi-resolution bone geometric model.

Using the movement patterns of reintroduced animals to improve reintroduction success

Current Zoology 2014年第4期60卷 515-526页

Despite their importance to conservation, reintroductions are still a risky endeavor and tend to fail, highlighting the need for more efficient post-release monitoring techniques. Reintroduced animals are released into unfamiliar novel environments and must explore their surroundings to gain knowledge in order to survive. According to theory, knowledge gain should be followed by subsequent changes to the animal’s movement behavior, making movement behavior an excellent indicator of reintroduction progress. We aim to conceptually describe a logical process that will enable the inclusion of behavior (in particular, movement behavior) in management decision-making post-reintroductions, and to do so, we provide four basic components that a manager should look for in the behaviors of released animals. The suggested components are release-site fidelity, recurring locations, proximity to other individuals, and individual variation in movement behavior. These components are by no means the only possible ones available to a manager, but they provide an efficient tool to understanding animals’ decision-making based on ecological theory; namely, the exploration-exploitation trade-off that released animals go through, and which underlies their behavior. We demonstrate our conceptual approach using data from two ungulate species reintroduced in Israel: the Persian fallow deerDama mesopotamicaand the Arabian oryxOryx leucoryx[Current Zoology60 (4): 515–526, 2014].

Short-term results of incremental penile girth enhancement using liquid injectable silicone： words of praise for a change

引用

Asian Journal of Andrology 2007年第3期9卷 408-413页

作者： YacovYacobi Alexander Tsivian Roman Grinberg oded Kessler Department of Urologic Surgery E. Wolfson Medical Center Holon 58100 Israel Theomim Clinic Ramat-Gan 52511 Israel

Aim： To report our experience with penile girth augmentation using liquid injectable silicone. Methods： Between August 2003 and July 2006, 324 men （mean age 35 years, range 19-65 years） received a series of liquid silicone subcutaneous injections between the penile skin and the corpora cavernosa on the dorsal and lateral aspects of the penile shaft, under local anesthesia. Digital photographs taken pre- and post-procedure （n = 324）, and penile contour measurements （n = 30） yielded objective results. Subjective results were derived from patient and partner testimony of satisfaction. Follow-up averaged 20 months （range 1-36 months）. Results： Three hundred and twenty-four procedures were primary augmentations. Most men （61%） were married, 7% were accompanied by their partners, and 93% were circumcised. The mean measured penile circumference was 9.5 cm （7.5-11.5 cm） pretreatment and 12.1 cm （10.3-15.3 cm） post-treatment （mean increase of 27% in circumference and 0.84 cm in diameter）. Patient and partner satisfaction was already expressed after the first two treatments. Sexual activity could be resumed after 8 h. Complications （mild bruising） were easily resolved. Conclusion： Penile girth augmentation using liquid injectable silicone yields very satisfactory short-term results with no immediate or short-term complications.

Objective To evaluate the efficacy of preventive treatment (PT) on alveolar pulmonary edema (APE) of cardiogenic origin using a monitor based on principles of internal thoracic impedance (ITI) *** We conducted blinded clinical trials on patients with ST-elevation myocardial infarction (STEMI) and monitored whether the condition would progress to APE. ITI was measured noninvasively by the Edema Guard Monitor (EGM, model RS-207) every 30 min. The measurement threshold for the diagnosis of APE was fixed at > 12% decrease in ITI from baseline as described in our methodology. The patients were divided into one group that received standard treatment after the appearance of clinical signs of APE without considering the prediction of APE by EGM devise (Group 1), and another group of asymptomatic patients in whom development of APE was predicted by using only EGM measurements (Group 2). The latter participants’PT consisted of furosemide, intravenous nitroglycerine and supplemental oxygen. Results One-hundred and fifty patients with acute STEMI were enrolled into this study. Group 1 included 100 patients (53% males, age 64.1 ±12.6 years). Treatment was started after the clinical appearance of overt signs of APE. Group 2 included 50 patients (54% males, age 65.2 ±11.9 years) who received PT based on EGMmeasurements. Group 2 had significantly fewer cases of APE (n = 4, 8%) than Group 1 (n = 100, 100%) (P > 0.001). While APE was lethal in six (6%) Group 1 patients, PT resulted in prompt resolution of APE in all four (8%) Group 2 patients. Conclusion ITI is a usefulmodality for early diagnosis and PT of pulmonary edema of cardiogenic origin.

A Novel Approach to Probability

引用

Advances in Pure Mathematics 2016年第4期6卷 201-211页

作者： oded Kafri Kafri Nihul Ltd. Tel Aviv Israel

When P indistinguishable balls are randomly distributed among L distinguishable boxes, and considering the dense system , our natural intuition tells us that the box with the average number of balls P/L has the highest probability and that none of boxes are empty;however in reality, the probability of the empty box is always the highest. This fact is with contradistinction to sparse system (i.e. energy distribution in gas) in which the average value has the highest probability. Here we show that when we postulate the requirement that all possible configurations of balls in the boxes have equal probabilities, a realistic “long tail” distribution is obtained. This formalism when applied for sparse systems converges to distributions in which the average is preferred. We calculate some of the distributions resulted from this postulate and obtain most of the known distributions in nature, namely: Zipf’s law, Benford’s law, particles energy distributions, and more. Further generalization of this novel approach yields not only much better predictions for elections, polls, market share distribution among competing companies and so forth, but also a compelling probabilistic explanation for Planck’s famous empirical finding that the energy of a photon is hv.
